Nonmedical use of prescription drugs has become the fastest growing drug problem in the United States, particularly among young adults. This study examines the reasons young polydrug users misuse prescription drugs, and explores how young users employ risk reduction strategies to minimize adverse consequences. The sample was recruited during 2008 and 2009 in Los Angeles and New York, and comprised 45 nonmedical users of prescription drugs, aged 16 to 25. Data from a semistructured interview were analyzed quantitatively and qualitatively. Participants reported nonmedical use of prescription drugs to change mood, to facilitate activity, and to monitor the intake of other substances. Commonly employed risk reduction strategies included calculating pill timing, dosage, and access, and monitoring frequency of use, particularly when combining different substances. Most study participants often planned drug use to occur within socially acceptable parameters, such that prescription drug misuse was a normalized feature of their everyday lives. PMID:25477621

We estimated prevalence and identified correlates of crack-cocaine injection among young injection drug users in the United States. We analyzed data from the second Collaborative Injection Drug Users Study (CIDUS II), a 1997-1999 cohort study of 18-30-year-old, street-recruited injection drug users from six US cities. Crack-cocaine injection was reported by 329 (15%) of 2198 participants. Prevalence varied considerably by site (range, 1.5-28.0%). No participants injected only crack-cocaine. At four sites where crack-cocaine injection prevalence was greater than 10%, recent (past 6 months) crack-cocaine injection was correlated with recent daily injection and sharing of syringes, equipment, and drug solution. Lifetime crack-cocaine injection was correlated with using shooting galleries, initiating others into drug injection, and having serologic evidence of hepatitis B virus and hepatitis C virus infection. Crack-cocaine injection may be a marker for high-risk behaviors that can be used to direct efforts to prevent HIV and other blood-borne viral infections.

The authors report the results of qualitative (n = 19) and quantitative (n = 545) interviews with young injection drug users (IDUs) in San Diego, California about their experiences using drugs in Tijuana, Mexico, and associated risks for HIV infection. Young IDUs who have ever traveled to Mexico (n = 365) used a variety of injection (54%) and noninjection (30%) drugs there and appear to be heavier users than those who have never traveled to Mexico. Sociocultural themes influencing drug use in Mexico included interactions among the purpose of travel, drug preference, and route of administration; familiarity with the border region; evolving relationships with the United States and Mexican drug markets; and the experience of crossing the U.S.-Mexico border. Interventions for IDUs in border regions need to be sensitive to the ethnicity, familiarity with the border region, and life history of participants, as well as differences in national policies that could influence drug use and risk for HIV on both sides of the border.

OBJECTIVES: To assess the demographic characteristics, psychiatric symptoms, substance use patterns, and sexual risk behaviors in a sample of club drug users to identify factors associated with unprotected sex during the 12 months prior to the interview. METHODS: This cross-sectional study employed the targeted sampling and ethnographic mapping approaches via face-to-face interviews conducted at bars and electronic music festivals using an adapted, semi-structured version of the Global Appraisal of Individual Needs questionnaire. The sample comprised 240 male and female young adults who had used ecstasy and/or LSD in the 90 days prior to the interview and who were not receiving treatment for alcohol or drug abuse. RESULTS: Of the 240 subjects selected (mean age: 22.9±4.5 years), 57.9% were men; of the male subjects, 52.5% reported having had unprotected sex in the previous 12 months. Of the total sample, 63.33% reported having had unprotected sex. Multivariate regression analysis showed that anal sex (PR = 1.26; 95% confidence interval (CI): 1.044–1.543; p = 0.017) and the use of alcohol/drugs to make sex last longer (PR = 1.430; 95% CI: 1.181–1.732; p<0.001) are associated with unprotected sex. CONCLUSIONS: The implementation of intervention strategies aimed at reducing sexually risky behaviors should take into consideration the specific characteristics of drug users and should include the development of safer sex negotiation skills.

This study examined associations between mortality and demographic and risk characteristics among young injection drug users in San Francisco, California, and compared the mortality rate with that of the population. A total of 644 young (<30 years) injection drug users completed a baseline interview and were enrolled in a prospective cohort study, known as the UFO ("U Find Out") Study, from November 1997 to December 2007. Using the National Death Index, the authors identified 38 deaths over 4,167 person-years of follow-up, yielding a mortality rate of 9.1 (95% confidence interval: 6.6, 12.5) per 1,000 person-years. This mortality rate was 10 times that of the general population. The leading causes of death were overdose (57.9%), self-inflicted injury (13.2%), trauma/accidents (10.5%), and injection drug user-related medical conditions (13.1%). Mortality incidence was significantly higher among those who reported injecting heroin most days in the past month (adjusted hazard ratio = 5.8, 95% confidence interval: 1.4, 24.3). The leading cause of death in this group was overdose, and primary use of heroin was the only significant risk factor for death observed in the study. These findings highlight the continued need for public health interventions that address the risk of overdose in this population in order to reduce premature deaths.

To describe the users' drug abuse characteristics, problematic behaviors associated with addiction, the motivation of teenagers and young adults to quit cocaine and/or crack abuse, and then compare these characteristics. A cross-section study was conducted with 2390 cocaine/crack users (teenagers from 14 to 19 years of age, and young adults from 20 to 24 years of age); 1471 were young adults and 919 were teenagers who had called a phone counseling service between January 2006 and December 2013. Semi-structured interviews were performed via phone calls. The questionnaires included sociodemographic information; assessment of the characteristics of cocaine/crack abuse; assessment of the problematic behaviors; also, the Contemplation Ladder was used to evaluate the stages of readiness to cease substance abuse. Participants reported using cocaine (48.2%), crack and other smoking forms (36.7%) and combined consumption of both drugs (15%). Young adults were more prone to using crack or crack associated with cocaine (OR=1.9; CI 95%=1.05-1.57) and they were exposed to substance abuse for longer than two years (OR=3.45; CI 95%=2.84-4.18), when compared to teenagers. On the other hand, they showed higher readiness to quit. Data shows important differences in drug abuse characteristics, problematic behaviors and motivation to cease substance abuse between teenager and young adult cocaine and/or crack users. Behaviors displayed by young adults involve greater physical, mental and social health damages. These findings reinforce the importance of public policy to act on prevention and promoting health, to increase protection factors among teenagers and lower risks and losses during adult life.

Research on pregnancy and sexual health among homeless youth is limited. In this study, qualitative interviews were conducted with 41 homeless young injection drug users (IDUs) in Los Angeles with a history of pregnancy. The relationship between recent pregnancy outcomes, contraception practices, housing status, substance use, utilization of prenatal care, and histories of sexual victimization are described. A total of 81 lifetime pregnancies and 26 children were reported. Infrequent and ineffective use of contraception was common. While pregnancy motivated some homeless youth to establish housing, miscarriages and terminations were more frequent among youth who reported being housed. Widespread access to prenatal and medical services was reported during pregnancy, but utilization varied. Many women continued to use substances throughout pregnancy. Several youth reported childhood sexual abuse and sexual victimization while homeless. Pregnancy presents a unique opportunity to encourage positive health behaviors in a high-risk population seldom seen in a clinical setting. PMID:18692891

Objectives. We examined correlates of incarceration among young methamphetamine users in Chiang Mai, Thailand in 2005 to 2006. Methods. We conducted a cross-sectional study among 1189 young methamphetamine users. Participants were surveyed about their recent drug use, sexual behaviors, and incarceration. Biological samples were obtained to test for sexually transmitted and viral infections. Results. Twenty-two percent of participants reported ever having been incarcerated. In multivariate analysis, risk behaviors including frequent public drunkenness, starting to use illicit drugs at an early age, involvement in the drug economy, tattooing, injecting drugs, and unprotected sex were correlated with a history of incarceration. HIV, HCV, and herpes simplex virus type 2 (HSV-2) infection were also correlated with incarceration. Conclusions. Incarcerated methamphetamine users are engaging in behaviors and being exposed to environments that put them at increased risk of infection and harmful practices. Alternatives to incarceration need to be explored for youths. PMID:18923109

Although studies have found that young adults who sell drugs are more likely to be involved in risky behaviors than those who do not sell drugs, there has been relatively little research that has explored heterogeneity among young adults who sell drugs. Using a pooled sample of 18 to 25 year olds from the National Survey on Drug Use and Health (2006-2010) who report past-year drug selling (N = 5,373), this study employs latent profile analysis to specify latent groups and assess the correlates of group membership. Findings indicate substantial differences among young adults who sell drugs. In particular, the analysis found four groups of drug sellers: normative (49.6%), club drug users (23.6%), polysubstance users (16.0%), and criminal offenders (10.8%). Club drug users were characterized by high levels of ecstasy and hallucinogen use, polysubstance users were more likely to be depressed and anxious, White and female than the other groups. Criminal offenders were overwhelmingly male and more likely to be comprised of African-Americans and Hispanics. RESULTS indicate that drug selling in early adulthood varies substantially. Contrary to media and popular notions most drug sellers are not involved in crime and polysubstance using drug sellers are in clear need of mental health services. Further, most drug sellers in this age range are White. Findings suggest that policy efforts that operate under the assumption of homogeneity of drug selling may be misguided.

Explanations and expectations: drug narratives among young cannabis users in treatment

This article analyses how young people enrolled in drug addiction treatment in Copenhagen, Denmark, explain their cannabis careers and how they view their possibilities for quitting drug use again. Inspired by Mead and narrative studies of health and illness, the article identifies four different drug use ‘aetiologies’ drawn upon by the interviewees. These cover childhood experiences, self-medication, the influence of friends and cannabis use as a specific lifestyle. A central argument of the article is that these explanations not only concern the past but also point towards the future by assigning the interviewee a more or less agential position in relation to drugs. Further, the drug narratives are viewed as interactional achievements, related to the social context in which they were produced, namely, the institutional setting of the treatment centres. The article is based on 30 qualitative interviews with young people in drug addiction treatment. PMID:25688710

Background Ecstasy use is prevalent among young people and often co-occurs with other drug use, but little is known about the past 12-month and lifetime psychiatric comorbidity and specific additional drug abuse among young adult ecstasy users in the general population. To provide this information, we compared current ecstasy users to former users, other illicit drug users, and non-illicit drug users. Method Data were gathered in a face-to-face survey of the United States conducted in the 2001–2002 (NESARC). Participants were household and group quarters residents aged 18–29 years (n = 8666). We measured current ecstasy use defined as any use in the past year; former ecstasy use as use prior to the past year only; other lifetime drug use included any drug other than ecstasy; lifetime non-illicit drug use as no illicit drug use. Associations were determined for nine other classes of illicit drugs, eight personality disorders, and seven mood and anxiety disorders. Results Of current ecstasy users, 44% used >3 other classes of illicit drugs in the past year, compared to 1.6% of non-ecstasy drug users. Current ecstasy use was associated with current anxiety (OR = 3.7), specifically panic disorder (OR = 7.7) and specific phobia (OR = 4.1), also alcohol abuse (OR = 21.6) and dependence (OR = 4.1) and any personality disorder (OR = 5.1) compared to non-illicit drug users. Conclusions Results indicate important differences in comorbidities of current and former ecstasy users compared to other drug users and lifetime non-illicit drug users that may affect phenotype definitions and etiologic studies. Ecstasy use may represent a distinct population of drug users for which unique treatments may be necessary. PMID:18524499

Club drug use and dependence among young adults recruited through time-space sampling.

Ketamine, methylenedioxymethamphetamine (MDMA/ecstasy), cocaine, gamma-hydroxybutyrate (GHB), methamphetamine, and d-lysergic acid diethylamide (LSD/acid) have been identified as "club drugs" because of their link to club culture among young adults. Yet little is known about users' demographic differences in the prevalence of club drugs. This study sought to provide a comprehensive profile of users' demographic differences in prevalence of club drug use and dependence. Using time-space sampling, a stratified sample of 400 18- to 29-year-old club-going young adults was recruited into the Club Drugs and Health Project. Though participants reported using an array of club drugs, almost all participants (90.0%) were cocaine users. Although there were several sexual orientation and gender differences in recent drug exposure, patterns of use (measured in days) were fairly similar across gender, sexual orientation, and age. Finally, a majority of individuals (58.5%) met or exceeded criteria for club drug dependence, with most (61.7%) indicating cocaine was the one drug causing them significant problems. Cocaine is a major drug in club culture. It is essential to develop culturally appropriate drug education and prevention initiatives for young adults using club drugs.

Despite good evidence of increased availability and use of amphetamines world-wide, relatively little is known about the epidemiology of young adult amphetamine use; relationships with social functioning, other drug use and mental health at this age; nor of the adolescent predictors of such use. We examined these issues using a representative cohort of young people followed-up in Victoria, Australia. A stratified, random sample of 1943 adolescents was recruited from secondary schools across Victoria at age 14-15 years. This cohort was interviewed on eight occasions until the age of 24-25 years (78% follow-up at that age). Cross-sectional and predictive associations were assessed using logistic regression. At age 24 years, 12% of the sample had used amphetamines in the past year, with 1-2% using at least weekly. Young adult amphetamine use was predicted strongly by adolescent drug use and was associated robustly with other drug use and dependence in young adulthood. Associations were stronger for more frequent users. Among young adults who had not been using amphetamines at age 20 years, the strongest predictor of use at age 24 years was the use of other drugs, particularly cannabis, at 20 years. Psychological distress did not predict independently an increased likelihood of amphetamine use in this cohort. Young people in Australia using amphetamine at age 24 years are highly likely to be significant polydrug users. The risks for both initiation of young adult amphetamine use, and maintenance of such use, pertain to the heavy use of other drugs. Interventions for heavy amphetamine users at this age are likely to require attention to multiple drug problems.

Young injection drug users (IDUs), a highly mobile population, engage in high levels of injecting risk behavior, yet little is understood about how such risk behavior may vary by the characteristics of the cities to which they travel, including the existence of a syringe exchange program (SEP), as well as travel partner characteristics. In 2004-2005, we conducted a 6-month prospective study to investigate the risk behavior of 89 young IDUs as they traveled, with detailed information gathered about 350 city visits. In multivariable analyses, travel to larger urban cities with a population of 500,000-1,000,000 was significantly associated with injecting drugs (adjusted odds ratio (AOR) = 3.71; 95 % confidence interval (CI), 1.56-8.82), ancillary equipment sharing (AES; AOR = 7.05; 95 % CI, 2.25-22.06) and receptive needle sharing (RNS; AOR = 5.73; 95 % CI, 1.11-27.95), as compared with visits to smaller cities with populations below 50,000. Region of the country, and the existence of a SEP within the city visited, were not independently associated with injecting drugs, AES, or RNS during city visits. Traveling with more than one injecting partner was associated with injecting drugs during city visits (AOR = 2.77; 95 % CI, 1.46-5.27), when compared with traveling alone. Additionally, both non-daily and daily/almost daily alcohol use during city visits were associated with AES (AOR = 3.37; 95 % CI, 1.42-7.68; AOR = 3.03; 95 % CI, 1.32-6.97, respectively) as compared with no alcohol consumption. Traveling young IDUs are more likely to inject when traveling with other IDUs and to engage in higher risk injection behavior when they are in large cities. Risk behavior occurring in city visits, including equipment sharing and alcohol consumption, suggests further need for focused interventions to reduce risk for viral infection among this population.

To describe temporal trends in methamphetamine use among young injection drug users (IDU) in San Francisco. Secondary analysis of cross-sectional baseline data collected for a longitudinal study of young IDU from 1998 to 2004. Participants were 1445 young IDU (<30 years old) who reported injection in the previous month, English-speaking, and recruited by street outreach methods. We examined trends for: lifetime (ever) and recent (30-day) methamphetamine use, including injected and non-injected, and by age group and sexual risk behaviour [men who have sex with men injecting drug users (MSM-IDU), male IDU (non-MSM) and female IDU]. In 1998, 1999, 2000, 2001, 2003 and 2004 we interviewed 237, 276, 431, 310, 147 and 44 participants, respectively. Overall, median age was 22 years [interquartile range (IQR) 20-25], 30.3% were women and median duration of injecting was 4.4 years (IQR 2-7). Prevalence of methamphetamine use was high, with 50.1% reporting recent injection, but overall there were no temporal increases in reported 'ever' injected use. Recent methamphetamine injection (past 30 days) increased significantly, and peaked at 60% in 2003. MSM-IDU had higher methamphetamine injection ever (92.3%) and recently (59.5%) compared to heterosexual male (non-MSM) IDU (81.6% and 47.3%, respectively) and to female IDU (78.4% and 46.1%, respectively). Despite reports of ubiquitous increases in methamphetamine use, there were no significant increases in 6 years in ever injecting methamphetamine overall among young IDU. MSM-IDU who reported the highest methamphetamine use overall reported some increases in recent injected use. The methamphetamine 'epidemic' was probably under way among young IDU earlier than other populations.

Studies have shown important gender differences among drug (including crack) users related to: drug use patterns; health risks and consequences; criminal involvement; and service needs/use. Crack use is prevalent in Brazil; however, few comparative data by sex exist. We examined and compared by sex key drug use, health, socio-economic indicators and service use in a bi-city sample of young (18-24 years), regular and marginalized crack users in Brazil. Study participants (total n = 159; n = 124 males and n = 35 females) were recruited by community-based methods from impoverished neighborhoods in Rio de Janeiro and Salvador. Assessments occurred by an anonymous interviewer-administered questionnaire and serum collection for blood-borne virus testing between November 2010 and June 2011. Descriptive statistics and differences for key variables by sex were computed; in addition, a 'chi-squared automatic interaction detector' ('CHAID') analysis explored potential primary factors differentiating male and female participants. Most participants were non-white, and had low education and multiple income sources. More women had unstable housing and income from sex work and/or panhandling/begging, whereas more men were employed. Both groups indicated multi-year histories of and frequent daily crack use, but virtually no drug injection histories. Men reported more co-use of other drugs. More women were: involved in sex-for-drug exchanges; blood-borne virus (BBV) tested and HIV+. Both groups reported similar physical and mental health patterns; however women more commonly utilized social or health services. The CHAID analysis identified sex work; paid work; begging/panhandling; as well as physical and mental health status (all at p < 0.05) as primary differentiating factors by sex. Crack users in our study showed notable differences by sex, including socio-economic indicators, drug co-use patterns, sex risks/work, BBV testing and status, and service utilization

Assessment of HIV testing among young methamphetamine users in Muse, Northern Shan State, Myanmar

PubMed Central

2014-01-01

Background Methamphetamine (MA) use has a strong correlation with risky sexual behaviors, and thus may be triggering the growing HIV epidemic in Myanmar. Although methamphetamine use is a serious public health concern, only a few studies have examined HIV testing among young drug users. This study aimed to examine how predisposing, enabling and need factors affect HIV testing among young MA users. Methods A cross-sectional study was conducted from January to March 2013 in Muse city in the Northern Shan State of Myanmar. Using a respondent-driven sampling method, 776 MA users aged 18-24 years were recruited. The main outcome of interest was whether participants had ever been tested for HIV. Descriptive statistics and multivariate logistic regression were applied in this study. Results Approximately 14.7% of young MA users had ever been tested for HIV. Significant positive predictors of HIV testing included predisposing factors such as being a female MA user, having had higher education, and currently living with one’s spouse/sexual partner. Significant enabling factors included being employed and having ever visited NGO clinics or met NGO workers. Significant need factors were having ever been diagnosed with an STI and having ever wanted to receive help to stop drug use. Conclusions Predisposing, enabling and need factors were significant contributors affecting uptake of HIV testing among young MA users. Integrating HIV testing into STI treatment programs, alongside general expansion of HIV testing services may be effective in increasing HIV testing uptake among young MA users. PMID:25042697

Attitudes towards drug legalization among drug users.

Trevino, Roberto A; Richard, Alan J

2002-01-01

Research shows that support for legalization of drugs varies significantly among different sociodemographic and political groups. Yet there is little research examining the degree of support for legalization of drugs among drug users. This paper examines how frequency and type of drug use affect the support for legalization of drugs after adjusting for the effects of political affiliation and sociodemographic characteristics. A sample of 188 drug users and non-drug users were asked whether they would support the legalization of marijuana, cocaine, and heroin. Respondents reported their use of marijuana, crack, cocaine, heroin, speedball, and/or methamphetamines during the previous 30 days. Support for legalization of drugs was analyzed by estimating three separate logistic regressions. The results showed that the support for the legalization of drugs depended on the definition of "drug user" and the type of drug. In general, however, the results showed that marijuana users were more likely to support legalizing marijuana, but they were less likely to support the legalization of cocaine and heroin. On the other hand, users of crack, cocaine, heroin, speedball, and/or methamphetamines were more likely to support legalizing all drugs including cocaine and heroin.

How do researchers categorize drugs, and how do drug users categorize them?

This paper considers drug classifications and terms widely used in US survey research, and compares these to classifications and terms used by drug users. We begin with a critical review of drug classification systems, including those oriented to public policy and health services as well as survey research. We then consider the results of a pile sort exercise we conducted with 76 respondents within a mixed method study of Southeast Asian American adolescent and young adult drug users in urban Northern California, USA. We included the pile sort to clarify how respondents handled specific terms which we understood to be related to Ecstasy and methamphetamines. Results of the pile sort were analyzed using graphic layout algorithms as well as content analysis of pile labels. Similar to the national surveys, our respondents consistently differentiated Ecstasy terms from methamphetamine terms. We found high agreement between some specific local terms (thizz, crystal) and popular drug terms, while other terms thought to be mainstream (crank, speed) were reported as unknown by many respondents. In labeling piles, respondents created taxonomies based on consumption method (in particular, pill) as well as the social contexts of use. We conclude by proposing that divergences between drug terms utilized in survey research and those used by drug users may reflect two opposing tendencies: the tendency of survey researchers to utilize standardized language that constructs persons and experiences as relatively homogeneous, varying only within measurable degrees, and the tendency of drug users to utilize specialized language (argot) that reflects their understandings of their experiences as hybrid and diverse. The findings problematize the validity of drug terms and categories used in survey research. PMID:24431475

We begin with a critical review of drug classification systems, including those oriented to public policy and health services as well as survey research. We then consider the results of a pile sort exercise we conducted with 76 respondents within a mixed method study of Southeast Asian American adolescent and young adult drug users in urban Northern California, USA. We included the pile sort to clarify how respondents handled specific terms which we understood to be related to Ecstasy and methamphetamines. Results of the pile sort were analyzed using graphic layout algorithms as well as content analysis of pile labels. Similar to the national surveys, our respondents consistently differentiated Ecstasy terms from methamphetamine terms. We found high agreement between some specific local terms ( thizz , crystal ) and popular drug terms, while other terms thought to be mainstream ( crank , speed ) were reported as unknown by many respondents. In labeling piles, respondents created taxonomies based on consumption method (in particular, pill ) as well as the social contexts of use. We conclude by proposing that divergences between drug terms utilized in survey research and those used by drug users may reflect two opposing tendencies: the tendency of survey researchers to utilize standardized language that constructs persons and experiences as relatively homogeneous, varying only within measurable degrees, and the tendency of drug users to utilize specialized language (argot) that reflects their understandings of their experiences as hybrid and diverse. The findings problematize the validity of drug terms and categories used in survey research.

The present study examined patterns of recent club drug use among 400 young adults (18–29) recruited using time-space sampling in NYC. Subjects had used at least one of six club drugs (MDMA, Ketamine, GHB, Cocaine, Methamphetamine, and LSD) within the prior 3 months. We used latent class analysis (LCA) to estimate latent groups based on patterns of recent club drug use and examined differences in demographic and psychological variables by class. A 3-class model fit the data best. Patterns were: Primary cocaine users (42% of sample), Mainstream users (44% of sample), and Wide-range users (14% of sample). Those most likely to be Primary cocaine users were significantly less likely to be heterosexual males and had higher educational attainment than the other two classes. Those most likely to be Wide-range users were less likely to be heterosexual females, more likely to be gay/bisexual males, dependent on club drugs, had significantly greater drug and sexual sensation-seeking, and were more likely to use when experiencing physical discomfort or pleasant times with others compared to the other two groups. Findings highlight the utility of using person-centered approaches to understand patterns of substance use, as well as highlight several patterns of club drug use among young adults. PMID:19939585

This paper assesses mortality rate for a cohort of drug users in Puerto Rico compared with that of the Island's general population, examining causes of death and estimating relative risk of death. Date and cause of death were obtained from death certificates during 1998. Vital status was confirmed through contact with subjects, family, and friends. HIV/AIDS was the major cause of death (47.7%), followed by homicide (14.6%), and accidental poisoning (6.3%). Females had higher relative risk of death than males in all age categories. Not living with a sex partner and not receiving drug treatment were related to higher mortality due to HIV/AIDS. Drug injection was the only variable explaining relative risk of death due to overdose. Puerto Rico needs to continue developing programs to prevent HIV/AIDS among drug users. Special attention should be given to young women, who appear to be in greatest need of programs to prevent early mortality.

There have been several recent efforts in the UK and the Netherlands to describe the harms of psychoactive substances based on ratings of either experts or drug users. This study aimed to assess the perceived benefits as well as harms of widely used recreational drugs, both licit and illicit, in an international sample of drug users. The survey was hosted at https://www.internationaldrugsurvey.org/ and was available in three languages. Residents reported their experience of 15 commonly used drugs or drug classes; regular users then rated their harms and benefits. In all, 5791 individuals from over 40 countries completed the survey, although the majority were from English speaking countries. Rankings of drugs differed across 10 categories of perceived benefits. Skunk and herbal cannabis were ranked consistently beneficial, whilst alcohol and tobacco fell below many classified drugs. There was no correlation at all between users’ harm ranking of drugs and their classification in schedules of the USA or ABC system in the UK. Prescription analgesics, alcohol and tobacco were ranked within the top 10 most harmful drugs. These findings suggest that neither the UK nor US classification systems act to inform users of the harms of psychoactive substances. It is hoped the results might inform health professionals and educators of what are considered to be both the harms and benefits of psychoactive substances to young people. PMID:23438502

The number of poly-drug users who mix use heroin and synthetic drugs (SD) is increasing worldwide. The objective of this study is to measure the risk factors for being infected with hepatitis C (HCV), human immunodeficiency virus (HIV) and syphilis among SD-only users, heroin-only users and poly-drug users. A cross-sectional study was conducted in 2015 from a national HIV surveillance site in Southwest China, 447 poly-drug, 526 SD-only and 318 heroin-only users were recruited. Poly-drug users have higher drug-use frequency, higher rates of drug-sharing and unsafe sexual acts than other users (p < 0.05). About a third (36.7%) of poly-drug users experienced sexual arousal due to drug effects, which is higher than the rate among other drug users. Poly-drug users had the highest prevalence of HIV (10.5%) and syphilis (3.6%), but heroin-only users had the highest prevalence of HCV (66.0%) (all p < 0.05) among three groups. Logistic regression shows among poly-drug users, having sex following drug consumption and using drugs ≥1/day were the major risk factors for both HIV (Adjusted odds ratio (AOR) = 2.4, 95% CI [1.8-3.4]; 2.3, [1.6-3.1]) and syphilis infection (AOR = 4.1, [2.1-6.9]; 3.9, [1.8-5.4]). Elevated risk of both HIV and syphilis infection have been established among poly-drug users.

Macro Social Flaws and Intervention's Unfinished Business: A Personal Note on Young People's Drug Use in Hong Kong.

PubMed

Cheung, Yuet W

2015-01-01

This paper traces how social, economic, and cultural changes in Hong Kong in the past five decades might have affected the pattern of illicit drug use among young people in Hong Kong. The prevalence of illicit drug use by young people had been very low before the 1990s, and like adult users, young users mostly used heroin. This pattern of drug use started to change in the late 1990s, when there was a sudden upsurge of drug use among young people, and psychoactive drugs such as ketamine quickly replaced heroin as the most popular drugs among them. An attempt is made to explain the new pattern of young people's drug use with respect to the changes of the social, economic and cultural conditions of Hong Kong since the 1960s, making use of Beck's risk society perspective and Parker's concept of normalization of recreational drug use. The identification of macro social flaws points to the need to address societal factors impeding successful interventions, which will involve reducing the blockage of upward mobility for young people, and providing them with the latest scientific knowledge of the physical and mental damages of ketamine and other psychoactive drugs for their better understanding of the risk of drug use.

This study examines drug effect-enhancing behaviors practiced by young adult users of the drug, Ecstasy. Between August 2002 and August 2004, 283 face-to-face interviews were conducted with active Ecstasy users. Study participants were recruited in the Atlanta, Georgia metropolitan area using a targeted sampling approach. The large majority of study participants (87%) engaged in at least one behavior specifically designed to bolster the effects of their Ecstasy use, with 61% of the study participants reporting having engaged in at least three such behaviors during the past 30 days. Taking steps to boost one's Ecstasy-related high was associated with binging on Ecstasy and a variety of adverse outcomes, such as experiencing a greater number of negative consequences resulting from Ecstasy use and experiencing more Ecstasy-related drug dependency symptoms. Multivariate analysis revealed several factors associated with greater involvement in effects-boosting behaviors, including race (not being African American), spending time with other drug users, using Ecstasy for its touch-enhancing qualities, enjoyment of the music-and-Ecstasy-use experience, and childhood maltreatment experiences. The implications of these findings for treatment, prevention, and intervention for drug problems among Ecstasy users are discussed.

Objectives To identify the type and extent of weapons being carried among young people in Scotland, and to determine the relation between use of illegal drugs and weapon carrying. Design Questionnaire school survey. Setting Independent schools in central Scotland and schools in Lanarkshire and Perth and Kinross. Participants 3121 students aged 11 to 16 in 20 schools. Main outcome measures Self completion questionnaire reporting history of drug use and weapon carrying. Results Overall, 34.1% of males and 8.6% of females reported having carried a weapon (P<0.0001), ranging from 29.2% of boys aged 11-13 (classes S1 to S2) to 39.3% of boys aged 13-15 (S3 to S4). These values are higher than those in a recent survey of young people in England. Weapon carrying in Lanarkshire was 70% higher for males than in the rural area of Perth and Kinross. Both males and females who had taken drugs were more likely to carry weapons (63.5% of male drug users versus 20.5% of non-users and 22.8% of female drug users versus 3.7% of non-users; both P<0.0001). The proportions of males carrying weapons who used none, one, two, three or four, or five or more illegal drugs were 21%, 52%, 68%, 74%, and 92% respectively. A similar trend was found among females. Conclusions Better information is needed on the nature and extent of weapon carrying by young people in the United Kingdom, and better educational campaigns are needed warning of the dangers of carrying weapons.

Drug users suffer harm from the injecting process, and clinical services are reporting increasing numbers presenting with skin-related problems such as abscesses and leg ulcers. Skin breakdown can lead to long-term health problems and increased service costs and is often the first indication of serious systemic ill health. The extent of skin problems in injecting drug users has not previously been quantified empirically, and there is a dearth of robust topical literature. Where skin problems have been reported, this is often without clear definition and generic terms such as 'soft tissue infection' are used which lack specificity. The aim of this study was to identify the range and extent of skin problems including leg ulceration in a sample of injecting drug users. Definitions of skin problems were developed and applied to descriptions from drug users to improve rigour. Data were collected in needle exchanges and methadone clinics across Glasgow, Scotland, from both current and former drug injectors using face-to-face interviews. Two hundred participants were recruited, of which 74% (n = 148) were males and 26% (n = 52) were females. The age range was 21-44 years (mean 35 years). Just under two thirds (64%, n = 127) were currently injecting or had injected within the last 6 months, and 36% (n = 73) had previously injected and had not injected for more than 6 months.Sixty per cent (n = 120) of the sample had experienced a skin problem, and the majority reported more than one problem. Most common were abscesses, lumps, track marks and leg ulcers. Fifteen per cent (n = 30) of all participants reported having had a leg ulcer. This is an original empirical study which demonstrated unique findings of a high prevalence of skin disease (60%) and surprisingly high rates of leg ulceration (15%). Skin disease in injecting drug users is clearly widespread. Leg ulceration in particular is a chronic recurring condition that is costly to treat and has

Illicit Drug use poses a substantial public health problem around the world, mainly affecting young people. Current estimates suggest that Iran has the highest rate of opium addiction per capita in the world. It has been suggested that multiple elements contribute to the process of drug use. The aim of this study is to explore the probable components in the society that might play a role in the initiation of drug use among young adults. The study is qualitative in nature. Twenty four in-depth interviews were conducted with drug-using young men (n = 10) and women (n = 10) and their family members (n = 4). Based on our data analysis, developing a pro-drug attitude, conformist attitude of society toward treating youth and young individuals, and having weak approach toward prevention were identified as important determinants of substance use. We recommend the need for early intervention, especially for at-risk communities. The results of this research suggest that dealing with a major problem such as drug use needs a comprehensive assessment of the context in which young people live and use substances. According to our findings, exploring young drug users experiences is not only important but also useful for policy makers to develop more effective prevention and intervention programs.

To examine the effects of a permissive attitude towards regular and occasional drug use, life satisfaction, self-esteem, depression, and other psychosocial variables in the drug use of psychoactive drug users. Psychosocial factors that might affect a permissive attitude towards regular / occasional drug use and life satisfaction were further explored. We analysed data of a sample of psychoactive drug users from a longitudinal survey of psychoactive drug abusers in Hong Kong who were interviewed at 6 time points at 6-month intervals between January 2009 and December 2011. Data of the second to the sixth time points were stacked into an individual time point structure. Random-effects probit regression analysis was performed to estimate the relative contribution of the independent variables to the binary dependent variable of drug use in the last 30 days. A permissive attitude towards drug use, life satisfaction, and depression at the concurrent time point, and self-esteem at the previous time point had direct effects on drug use in the last 30 days. Interestingly, permissiveness to occasional drug use was a stronger predictor of drug use than permissiveness to regular drug use. These 2 permissive attitude variables were affected by the belief that doing extreme things shows the vitality of young people (at concurrent time point), life satisfaction (at concurrent time point), and self-esteem (at concurrent and previous time points). Life satisfaction was affected by sense of uncertainty about the future (at concurrent time point), self-esteem (at concurrent time point), depression (at both concurrent and previous time points), and being stricken by stressful events (at previous time point). A number of psychosocial factors could affect the continuation or discontinuation of drug use, as well as the permissive attitude towards regular and occasional drug use, and life satisfaction. Implications of the findings for prevention and intervention work targeted at

Energy drinks are becoming increasingly popular among young people. The purpose of this study was to determine the prevalence of energy drink consumption and its associations with socio-demographic characteristics, alcohol, cigarette and illicit drug use in a population-based sample of young adults participating in the Western Australian Pregnancy Cohort (Raine) Study. We used self-administered questionnaires to assess energy drink consumption patterns, alcohol intake, cigarette and illicit drug use at the 20-year cohort follow-up. Data was also collected on socio-demographics, physical activity, body mass index (BMI) and dietary intake. Our sample included 1234 participants (47% male, mean age 20 ± 0.5 years). We considered energy-drink consumption as a categorical (users versus non-users) variable. Overall, 48% of participants consumed energy drinks at least once per month, with an average intake of 1.31 ± 0.75 cans per day amongst energy drink users. The most significant correlates of energy drink use were being in part-time or full-time employment, being male, being a cigarette smoker, having heavier alcoholic spirit consumption patterns and being an ecstasy user (all p<0.05). No significant associations were observed with BMI or dietary intake. Australian energy drink users tend to have heavier alcohol consumption patterns be a cigarette smoker and use illicit drugs relative to non-users. More research is needed regarding the health risks associated with energy drink use in young adults, including their possible role in the development of substance abuse problems. Copyright © 2013.

This article presents the partial results of a multicenter, cross-temporal study, which was performed using multiple methods, and involved seven Latin-American countries and Canada. The results presented refer to the city center of Rio de Janeiro (n=108). The central question of the study was: 'How do illicit drug users' relatives and acquaintances describe protective and risk factors, prevention initiatives, treatment services, laws and policies regarding illicit drugs?' The quantitative data was collected using an instrument containing closed questions. In total, 108 young adults (18 years of age or older) were interviewed, who stated being affected by the drug although they were not users. For 104 interviewees (96%), negligence is the family dynamics that causes the greatest exposure to drugs, and 106 (98%) consider that parent support is what offers the greatest protection. Policies, the police and the criminal system have neither reduced drug use nor do they protect users.

Science and scepticism: Drug information, young men and counterpublic health.

PubMed

Farrugia, Adrian; Fraser, Suzanne

2017-11-01

It is perhaps no surprise that young people can be sceptical of the drug-related information they receive in school-based health education, health promotion and the media. Significant societal anxiety surrounds young people's drug consumption, so it is tempting to approach this scepticism as a problem to be solved. In this article, we look closely at a group of young Australian men (n = 25), all of whom hold deeply sceptical views about the drug information they received in schools, social marketing campaigns and public speech generally. We do not approach their scepticism as a problem to be solved in itself, however. Instead, we analyse its origins and how it relates to the way knowledge is constructed in drug education, health promotion and media accounts of drug use. To conceptualise this scepticism, we draw on Irwin and Michael's analysis of the changing relationship between science and society, Warner's theorisation of publics and counterpublics, and Race's related notion of 'counterpublic health'. The article organises the data into three key themes: scepticism about the accuracy of the claims made about drug risks and dangers, scepticism about representations of drug users, and scepticism about the motivations behind the health messages and drug policy in general. We then draw these different aspects of scepticism together to argue that the young men can be seen to constitute a health 'counterpublic', and we consider the implications of this approach, arguing for what has been described as a more diplomatic engagement between science and publics.

The extent to which young adult former cannabis users fare better than infrequent users is unclear. We investigated the association between cannabis use status at age 23 and substance use and mental health outcomes at age 27. Data were from the 20+ year cohort of the PATH Through Life Study. Lifetime cannabis users (n = 1410) at age 23 were classified as former/occasional/regular users. Multivariable logistic regression was used to estimate the association between cannabis use status at age 23 and six outcomes assessed at age 27. Compared with occasional cannabis users: (i) former users had odds of subsequent tobacco use [odds ratio (OR) = 0.67, 95% confidence interval (CI) 0.52-0.85], illicit drug use (cannabis, OR = 0.22, 95% CI 0.17-0.28; other illicit drugs, OR = 0.29, 95% CI 0.22-0.39) and mental health impairment (OR = 0.71, 95% CI 0.55-0.92) that were 29-78% lower; and (ii) regular users had odds of subsequent frequent alcohol use (OR = 2.34, 95% CI 0.67-1.34), tobacco use (OR = 3.67, 95% CI 2.54-5.30), cannabis use (OR = 11.73, 95% CI 6.81-20.21) and dependence symptoms (OR = 12.60, 95% CI 8.38-18.94), and other illicit drug use (OR = 2.95, 95% CI 2.07-4.21) that were 2-13 times greater. Associations attenuated after covariate adjustment, and most remained significant. Clear associations exist between cannabis use status in young adulthood and subsequent mental health and substance use. While early intervention remains important to prevent regular cannabis use and the associated harms, experimentation with cannabis use in the years leading into young adulthood may not necessarily determine an immutable pathway to mental health problems and illicit substance use.

Little is known about nonmedical use of prescription drugs among non-college-attending young adults in the United States. Data were drawn from 36,781 young adults (ages 18-22 years) from the 2008-2010 National Survey on Drug Use and Health public use files. The adjusted main effects for current educational attainment, along with its interaction with gender and race/ethnicity, were considered. Compared to those attending college, non-college-attending young adults with at least and less than a HS degree had a higher prevalence of past-year nonmedical use of prescription opioids [NMUPO 13.1 and 13.2 %, respectively, vs. 11.3 %, adjusted odds ratios (aORs) 1.21 (1.11-1.33) and 1.25 (1.12-1.40)], yet lower prevalence of prescription stimulant use. Among users, regardless of drug type, non-college-attending youth were more likely to have past-year disorder secondary to use [e.g., NMUPO 17.4 and 19.1 %, respectively, vs. 11.7 %, aORs 1.55 (1.22-1.98) and 1.75 (1.35-2.28)]. Educational attainment interacted with gender and race: (1) among nonmedical users of prescription opioids, females who completed high school but were not enrolled in college had a significantly greater risk of opioid disorder (compared to female college students) than the same comparison for men; and (2) the risk for nonmedical use of prescription opioids was negligible across educational attainment groups for Hispanics, which was significantly different than the increased risk shown for non-Hispanic whites. There is a need for young adult prevention and intervention programs to target nonmedical prescription drug use beyond college campuses.

Prescription Drug Misuse Among Club Drug-Using Young Adults

Nonmedical prescription (Rx) drug use has recently increased, particularly among young adults. Using time-space sampling to generate a probability-based sample of club-going young adults (18–29), 400 subjects provided data on Rx drug misuse. Club-going young adults misuse Rx drugs at high rates. An overwhelming majority of the sample indicated lifetime use of pain killers, sedatives, and stimulants. A majority indicated recent pain killer use. Variations by gender and sexuality exist in this population. Young lesbian/bisexual women emerged as the group most likely to abuse Rx drugs. Research into the contexts influencing these patterns is imperative. PMID:17994483

Studies of injection drug use cessation have largely sampled adults in drug treatment settings. Little is known about injection cessation and relapse among young injection drug users (IDU) in the community. A total of 365 HCV-negative IDU under age 30 years were recruited by street outreach and interviewed quarterly for a prospective cohort between January 2000 and February 2008. Participants were followed for a total of 638 person-years and 1996 visits. We used survival analysis techniques to identify correlates of injection cessation (> or =3 months) and relapse to injection. 67% of subjects were male, median age was 22 years (interquartile range (IQR) 20-26) and median years injecting was 3.6 (IQR 1.3-6.5). 28.8% ceased injecting during the follow-up period. Among those that ceased injecting, nearly one-half resumed drug injection on subsequent visits, one-quarter maintained injecting cessation, and one-quarter were lost to follow-up. Participating in a drug treatment program in the last 3 months and injecting less than 30 times per month were associated with injection cessation. Injecting heroin or heroin mixed with other drugs, injecting the residue from previously used drug preparation equipment, drinking alcohol, and using benzodiazepines were negatively associated with cessation. Younger age was associated with relapse to injection. These results suggest that factors associated with stopping injecting involve multiple areas of intervention, including access to drug treatment and behavioral approaches to reduce injection and sustain cessation. The higher incidence of relapse in the younger subjects in this cohort underscores the need for earlier detection and treatment programs targeted to adolescents and transition-age youth.

Despite Thailand's war on drugs, methamphetamine ("yaba" in Thai) use and the drug economy both thrive. This analysis identifies predictors of incident and recurrent involvement in the sale or delivery of drugs for profit amongst young Thai yaba users. Between April 2005 and June 2006, 983 yaba users, ages 18-25, were enrolled in a randomized behavioural intervention in Chiang Mai Province (415 index and 568 of their drug network members). Questionnaires administered at baseline, 3-, 6-, 9-, and 12-month follow-up visits assessed socio-demographic factors, current and prior drug use, social network characteristics, sexual risk behaviours and drug use norms. Exposures were lagged by three months (prior visit). Outcomes included incident and recurrent drug economy involvement. Generalized linear mixed models were fit using GLIMMIX (SASv9.1). Incident drug economy involvement was predicted by yaba use frequency (adjusted odds ratio [AOR]: 1.05; 95% confidence interval [CI]: 1.01, 1.10), recent incarceration (AOR: 2.37; 95% CI: 1.07, 5.25) and the proportion of yaba-using networks who quit recently (AOR: .34; 95% CI: .15, .78). Recurrent drug economy involvement was predicted by age (AOR: 0.81; 95% CI: 0.68, 0.96), frequency of yaba use (AOR: 1.06; 95% CI: 1.02, 1.09), drug economy involvement at the previous visit (AOR: 2.61; CI: 1.59, 4.28), incarceration in the prior three months (AOR: 2.29; 95% CI: 1.07, 4.86), and the proportion of yaba-users in his/her network who quit recently (AOR: .38; 95% CI: .20, .71). Individual drug use, drug use in social networks and recent incarceration were predictors of incident and recurrent involvement in the drug economy. These results suggest that interrupting drug use and/or minimizing the influence of drug-using networks may help prevent further involvement in the drug economy. The emergence of recent incarceration as a predictor for both models highlights the need for more appropriate drug rehabilitation programmes and

Little is known about the engagement of young people who use drugs (PWUD) in harm reduction programs (HRPs), and few studies have included non-opioid users and non-injectors. While HRPs have effectively engaged PWUD, young people are under-represented in their services. The Injection Drug Users Health Alliance Citywide Study (IDUCS) is the largest community-based study of PWUD in HRPs in the US. From 2014-2015, 2421 HRP participants across New York City (NYC) completed a cross-sectional survey. We investigated differences in socio-demographics, service utilization, and risk behaviors between young (aged 18-30) and older participants and examined factors associated with overdose among young participants. The study included 257 young participants. They were significantly more likely than older participants to be white, educated, uninsured, unstably housed or homeless, and have a history of incarceration and residential drug treatment. They were more likely to report recent overdose but less likely to report knowledge of naloxone. Young participants also had higher rates of alcohol, marijuana, benzodiazepine, and injection drug use, and related risk behaviors such as public injection. Factors associated with past year overdose among young participants included experiencing symptoms of psychological distress (AOR=9.71), being unstably housed or homeless (AOR=4.39), and utilizing detox (AOR=4.20). Young PWUD who access services at HRPs in NYC differ significantly from their older counterparts. New York City and other urban centers that attract young PWUD should consider implementing harm reduction oriented services tailored to the unique needs of young people. Copyright © 2017.

There are few studies exploring the social context of controlled drug use amongst young people in Indonesia. This qualitative study examines the experience of young people in a slum area (lorong) in Makassar, eastern Indonesia, who use drugs but are not drug dependent and who employ various forms of self regulation to control their use. Semi-structured interviews were conducted with eight controlled drug users. The study found that whilst controlled drug users lived in a drug risk environment, they were not deeply embedded in the street culture, risk-taking practises and drug scene within their locality. Their employment, albeit in the informal economy and in low-paid jobs, facilitated their perspective that the status of rewa (a local construct of masculinity) and gaul (being sociable and up-to-date) could and should be accomplished through conventional means such as jobs and halal (legitimate) income. Their employment generated both direct benefit (legitimate income) and indirect benefit, including meaningful activities, structured time, positive identity and wider social networks (bridging social capital). This enabled them to have a stake in mainstream society and provided an incentive to control drug use. All factors which are protective against escalation into problematic drug use. The study showed the importance of sociological concepts of direct and indirect benefits of employment and of social capital in understanding the social context of controlled drug use amongst young people in the lorong. Additionally, drug policy should be more cognizant of the social vulnerability in the lorong and of the need to increase access to employment amongst young people in order to potentially decrease the likelihood of problematic drug use.

To fight against the rapid growth of synthetic drugs, the Chinese government has strengthened the controls and regulation, incorporated synthetic drugs into the new detoxification system, and changed the inconsistent governance of synthetic and traditional drugs. This, however, has not stopped the spread of synthetic drugs among young urbanites. While scholars have focused on the loopholes and defects of specific drug control regulations, ethnographic inquiries illustrate how and why control does not work, or is even resisted by young drug users. In-depth qualitative interviews were conducted with 28 individuals aged between 20 and 35, recruited from a cohort of synthetic drug users in a Shanghai drug rehabilitation centre. Audio-recorded interviews elicited accounts of their daily experiences of drug use as well as their perspectives on the impact of the government's new drug control policies. The main themes voiced by our respondents include: (1) synthetic drugs are not addictive, and are used to feel 'high'; (2) synthetic drugs are used to achieve their goals, which are otherwise impossible through mainstream means; (3) users are confident that they will be able to manage the use of synthetic drugs without harm to themselves; (4) their worries concern administrative punishment rather than consequences to health. The participants of this study did not support the government's attempts to control the use of synthetic drugs. They viewed their use as rational recreation under the perceived boundaries of 'acceptable risks'. Even in the context of severe control, synthetic drugs have strong appeal to youths. Drug policy should acknowledge the experiences of users and consider the socio-cultural contexts of youth drug-taking. The personal experience of participants could help improve the Chinese Drug Control Act and regulations. Copyright © 2014 Elsevier B.V. All rights reserved.

PURPOSE Little is known about nonmedical use of prescription drugs among non-college attending young adults in the United States. METHODS Data was drawn from 36,781 young adults (ages 18–22 years) from the 2008–2010 National Survey on Drug Use and Health public use files. The adjusted main effects for current educational attainment, along with its interaction with gender and race/ethnicity, were considered. RESULTS Compared to those attending college, non-college attending young adults with at least and less than a HS degree had a higher prevalence of past-year nonmedical use of prescription opioids (NMUPO: 13.1% and 13.2%, respectively, vs. 11.3%, adjusted Odds Ratios [aORs]: 1.21 [1.11–1.33] and 1.25 [1.12–1.40]), yet lower prevalence of prescription stimulant use. Among users, regardless of drug type, non-college attending youth were more likely to have past year disorder secondary to use (e.g., NMUPO: 17.4% and 19.1%, respectively, vs. 11.7%, aORs: 1.55 [1.22–1.98] and 1.75 [1.35–2.28]). Educational attainment interacted with gender and race: 1) among nonmedical users of prescription opioids, females who completed high school but were not enrolled in college had a significantly greater risk of opioid disorder (compared to female college students) than the same comparison for men; and 2) the risk for nonmedical use of prescription opioids was negligible across educational attainment groups for Hispanics, which was significantly different than the increased risk shown for Non-Hispanic whites. CONCLUSIONS There is a need for young adult prevention and intervention programs to target nonmedical prescription drug use beyond college campuses. PMID:25427665

Despite cannabis use among adolescents has shown to be related to psychosocial and mental health problems, the demand from adolescents for professional help is very low, and determinants of motivation for change among nonclinical populations remain unknown. The purpose of this study was to assess motivation for change among young cannabis users and to identify determinants of intention to change and self-change, as well as perceived barriers to seeking professional help. 261 cannabis users aged 16-21 participated in a computerized survey in Spain. Data from this cross-sectional study indicated that few users intend to stop taking the drug. Determining factors of intention to change were the following: having more drug-related problems, paranoid symptomatology and greater concern about the consequences of use. Self-change was facilitated by lower use of cannabis, and could be hindered by tobacco smoking and cannabis dependence. Lack of awareness of the problems and the desire to solve one's problems alone constitute the main barriers to seeking professional help. Adolescent cannabis users show low motivation for change though experiencing more problems associated with its use emerges as a determinant of increased motivation. Several barriers impede this motivation from turning into treatment demand. Copyright © 2012 S. Karger AG, Basel.

2013-11-01

Cognitive impairment has been found to be reversible in people with substance abuse, particularly those using ketamine. Ketamine users are often poly-substance users. This study compared the cognitive functions of current and former ketamine users who were also abusing other psychoactive substances with those of non-users of illicit drugs as controls. One hundred ketamine poly-drug users and 100 controls were recruited. Drug users were divided into current (n = 32) and ex-users (n = 64) according to the duration of abstinence from ketamine (>30 days). The Beck Depression Inventory (BDI), the Hospital Anxiety Depression Scale (HADSA) and the Severity of Dependence Scale (SDS) were used to evaluate depression and anxiety symptoms and the severity of drug use, respectively. The cognitive test battery comprised verbal memory (Wechsler Memory Scale III: Logic Memory and Word List), visual memory (Rey-Osterrieth Complex Figure, ROCF), executive function (Stroop, Wisconsin Card Sorting Test, and Modified Verbal Fluency Test), working memory (Digit Span Backward), and general intelligence (Information, Arithmetic and Digit-Symbol Coding) tests. Current users had higher BDI and HADSA scores than ex-users (p < 0.001 for BDI and p = 0.022 for HADSA) and controls (p < 0.001 for BDI and p = 0.002 for HADSA). Ex-users had higher BDI (p = 0.006) but equal HADSA scores (p = 1.000) compared to controls. Both current and ex-users had lower scores on Logical Memory delayed recall (p = 0.038 for current users and p = 0.032 for ex-users) and ROCF delayed recall (p = 0.033 for current users and p = 0.014 for ex-users) than controls. Current users also performed worse on ROCF recognition than controls (p = 0.002). No difference was found between the cognitive functions of current and ex-users. Ketamine poly-drug users displayed predominantly verbal and visual memory impairments, which persisted in ex-users. The interactive effect of ketamine and poly-drug use on memory needs further

Female injection drug users (IDUs) represent a large proportion of persons infected with HIV in the United States, and women who inject drugs have a high incidence of hepatitis B virus (HBV) and hepatitis C virus (HCV) infection. Therefore, it is important to understand the role of gender in injection risk behavior and the transmission of blood-borne virus. In 2000-2002, 844 young (<30 years old) IDUs were surveyed in San Francisco. We compared self-reported risk behavior between 584 males and 260 female participants from cross-sectional baseline data. We used logistic regression to determine whether demographic, structural, and relationship variables explained increased needle borrowing, drug preparation equipment sharing, and being injected by another IDU among females compared to males. Females were significantly younger than males and were more likely to engage in needle borrowing, ancillary equipment sharing, and being injected by someone else. Females were more likely than males to report recent sexual intercourse and to have IDU sex partners. Females and males were not different with respect to education, race/ethnicity, or housing status. In logistic regression models for borrowing a used needle and sharing drug preparation equipment, increased risk in females was explained by having an injection partner who was also a sexual partner. Injecting risk was greater in the young female compared to male IDUs despite equivalent frequency of injecting. Overlapping sexual and injection partnerships were a key factor in explaining increased injection risk in females. Females were more likely to be injected by another IDU even after adjusting for years injecting, being in a relationship with another IDU, and other potential confounders. Interventions to reduce sexual and injection practices that put women at risk of contracting hepatitis and HIV are needed.

Background/Objectives Rampant tooth decay has been reported among methamphetamine users. We investigated the prevalence of dental disease and associated risk behaviors in methamphetamine users compared to heroin users. Methods This pilot project is a cross-sectional study of an on-going cohort of young adult injection-drug users (IDUs) in San Francisco. An oral health questionnaire was administered by a research-assistant, and two dentists performed clinical examinations to record the Decayed-Missing-Filled-Surfaces (DMFS) index, presence of residual roots, the Simplified Oral Hygiene Index, and salivary hypofunction. Results The prevalence of dental disease among 58 young adult IDUs was strikingly high compared to the U.S. general population, however, there was no difference in the level of dental disease between the methamphetamine and heroin users in this study. The mean DMFS and number of decayed surfaces exceeded 28 in both groups. Conclusions While no difference in dental disease between methamphetamine and heroin users was detected, we found a high prevalence of caries and caries-associated behaviors in this sample of young adult IDUs. Clinical Implications Given the high level of dental disease observed in this population of young adult IDUs, one next step may be to explore the feasibility and effectiveness of providing low-intensity preventative measures (e.g., distribution of chlorhexidine rinses, xylitol gum, application of fluoride varnishes) through outreach workers.

Repeated ecstasy (MDMA) use is reported to impair cognition and cause increased feelings of depression and anxiety. Yet, many relevant studies have failed to control for use of drugs other than MDMA, especially marijuana (THC). To address these confounding effects we compared behavioural performance of 11 MDMA/THC users, 15 THC users and 15 non-drug users matched for age and intellect. We tested the hypothesis that reported feelings of depression and anxiety and cognitive impairment (memory, executive function and decision making) are more severe in MDMA/THC users than in THC users. MDMA/THC users reported more intense feelings of depression and anxiety than THC users and non-drug users. Memory function was impaired in both groups of drug users. MDMA/THC users showed slower psychomotor speed and less mental flexibility than non-drug users. THC users exhibited less mental flexibility and performed worse on the decision making task compared to non-drug users but these functions were similar to those in MDMA/THC users. It was concluded that MDMA use is associated with increased feelings of depression and anxiety compared to THC users and non-drug users. THC users were impaired in some cognitive abilities to the same degree as MDMA/THC users, suggesting that some cognitive impairment attributed to MDMA is more likely due to concurrent THC use.

Aims As part of a larger study on prescription drug misuse among young adults active in urban nightlife scenes, we examined participants’ motivations for misuse. Prescription painkillers, stimulants and sedatives were the primary substances of interest. Methods Participants were recruited from nightlife venues in New York using time-space sampling. Subjects completed a mixed-methods assessment at project research offices. The data presented here are from a subsample of 70 qualitative interviews conducted during the baseline assessment. Findings We identified experimentation and a “work hard, play hard” ethos as key motivations for misusing prescription drugs and argue that these motivations are specific, though not necessarily unique, to the participants’ social location as young adults. These findings highlight the role of life stage and social context in the misuse of prescription drugs. Conclusion Future studies of prescription drug misuse should pay attention to the larger social contexts in which users are embedded and, therefore, make decisions about how and why to misuse. Moving beyond the very broad concepts of “recreation” and “self-medication” presently established in the research, policies targeting young adults may want to tailor intervention efforts based on motivations.

The language of community is ubiquitous in academic, public health, and policy discourse about drug using populations. Yet, it has been argued that in some settings, the parameters of “the drug user community” are far from self-evident. We undertook this ethnographic investigation to explore experiences and understandings of a “drug user community” (sometimes referred to more specifically as a “street youth community”) among young people entrenched in Vancouver’s inner city drug scene. Our findings revealed that in this context, conventional notions of community—that is, a social network characterized by commonality, mutual responsibility, solidarity, and/or stability—resonated with some youth. However, most questioned the value of membership within this community, in which what they had in common with other youth were ongoing experiences of poverty, marginalization, and social exclusion. Many felt membership in the drug user community precluded their ability to be responsible and productive citizens within the wider community of “mainstream society.” Experiences of resource deprivation and everyday violence on the streets led many participants to emphasize the limited possibilities for community among their peers. We argue that it is important to critically examine heretofore essentializing assumptions about the nature of inner city drug user or street youth communities in order to better understand young people’s needs and desires in these settings.

Recently, large increases have been noted in injection drug use and HIV prevalence among drug users in Indonesia. The objective of this study was to examine the experience of drug users with HIV testing in Bali, Indonesia. In-depth interviews were conducted with a sample of 40 drug users who had injected heroin in the Denpasar, Bali area. The users' experience with testing highlighted the importance of pre- and post-test counselling that provides clear information, confidentiality and assistance in developing social support.

'I guess my own fancy screwed me over': transitions in drug use and the context of choice among young people entrenched in an open drug scene

PubMed Central

2010-01-01

Background There is growing interest in describing the broader risk trajectories experienced by young people who use drugs - that is, in describing the sequences of drug use transitions experienced by youth in relation to evolving understandings of risk and harm. This study sought to examine young people's perspectives regarding the evolution of their drug use in the context of a local drug scene in Vancouver, Canada. Methods Semi-structured qualitative interviews with 38 individuals recruited from a cohort of young drug users known as the At-risk Youth Study (ARYS) were supplemented by ongoing ethnographic fieldwork (e.g., observations and informal conversations with youth) conducted within the same cohort population. Interviews were transcribed verbatim and a thematic analysis was conducted. Results The majority of youth characterized past transition events as non-exceptional, largely 'spur-of-the-moment' decisions motivated by evolving feelings of curiosity. At the same time, participants' reflections indicated that the social, structural and material contexts of drug scene entrenchment play a powerful role in shaping these decisions and transition experiences. Conclusions Importantly, as young people become increasingly entrenched in the local drug scene, drug use transitions seem to constitute increasingly relevant (and even 'inevitable') choices congruent with everyday lived experience. The implications of these findings for the development of meaningful interventions for youth are discussed. PMID:20222984

Decades of research have demonstrated the importance of social influence in initiation and maintenance of drug use, but little is known about neural mechanisms underlying social influence in young adults who use recreational drugs. To better understand whether the neural and/or behavioral response to social influence differs in young adults using illicit drugs, 20 marijuana-using young adults (MJ) aged 18-25, and 20 controls (CON) performed a decision-making task in the context of social influence, while they underwent functional magnetic resonance imaging scans. A priori analyses focused on the nucleus accumbens (NAc), with post hoc analyses in the rest of the striatum. In this task, participants could choose to either follow or go against group influence. When subjects applied social information to response choice selection (independent of following or going against group influence), we observed activation in the middle striatum (caudate), in the MJ group only, that extended ventrally into the NAc. MJ users but not CON showed greater activation in the NAc but not the caudate while making choices congruent with group influence as opposed to choices going against group influence. Activation in the NAc when following social influence was associated with amount of drug use reported. In contrast, during the feedback phase of the task we observed significant NAc activation in both MJ and CON, along with dorsal caudate activation only in MJ participants. This NAc activation did not correlate with drug use. This study shows that MJ users, but not CON, show differential brain activation across striatal subregions when applying social information to make a decision, following versus going against a group of peers, or receiving positive feedback. The current work suggests that differential neural sensitivity to social influence in regions such as the striatum may contribute to the development and/or maintenance of marijuana use.

Tobacco may mask poorer episodic memory among young adult cannabis users.

2015-09-01

Co-occurring cannabis and tobacco use has become increasingly prevalent among young adults, but it is not clear how tobacco use may alter the neurocognitive profile typically observed among cannabis users. Although there is substantial evidence citing cannabis and tobacco's individual effect on episodic memory and related brain structures, few studies have examined the effect of combined cannabis and tobacco use on memory. This investigation examined relationships between amount of past year cannabis and tobacco use on 4 different indices of episodic memory among a sample of young adults who identified cannabis as their drug of choice. Results indicated that more cannabis use was linked with poorer initial acquisition, total learning, and delayed recall on the Hopkins Verbal Learning Test-Revised, but only among cannabis users who sporadically smoked cigarettes in the past year. Conversely, the amount of past year cannabis use was not associated with episodic memory performance among individuals who more consistently smoked cigarettes in the past year. These differences could not be explained by several relevant potential confounds. These findings provide important insight into a potential mechanism (i.e., attenuation of cognitive decrements) that might reinforce use of both substances and hamper cessation attempts among cannabis users who also smoke cigarettes. Ongoing and future research will help to better understand how co-use of cannabis and tobacco affects memory during acute intoxication and abstinence and the stability of these associations over time.

2015-06-01

The objectives of this study were to (1) identify and characterize heavy users of prescription drugs among persons aged 60 years and above; (2) investigate the association of demographic, socioeconomic, and health-related variables with being a heavy drug user; and (3) study the most frequently used drugs among heavy drug users and development in use over time. This is a descriptive study. Heavy drug users were defined as the accumulated top 1 percentile who accounted for the largest share of prescription drug use measured in number of dispensed defined daily doses (DDDs). The nationwide Danish registers were used to obtain data. Multivariable logistic binary regression was used to determine which factors were associated with being a heavy drug user. Heavy drug users among persons aged 60 years and above accounted for 6.8, 6.0, and 5.5% of prescription drug use in 2002, 2007, and 2012, respectively. Male gender, those aged 60-69 years, being divorced, shorter education, low annual income, and recent hospitalization were all significantly associated with being in the top 1 percentile group of drug users (p < 0.05). The ten most frequently used drug classes among heavy drug users accounted for 75.4% of their use in 2012, and five of these were cardiovascular drugs. The development over time for the ten most used drug classes followed the same pattern among heavy drug users and in the general population. There is a skewed utilization of prescription drugs. Contrary to earlier findings, being male was associated with heavy prescription drug use both with respect to number of drugs used and drug expenditure.

Little is known about young adult medical marijuana patients (MMP) and their marijuana using patterns and practices, which includes frequency of use, sourcing of marijuana products, forms/modes of administration, and patterns of illicit/prescription drug misuse, compared to non-patient marijuana users (NPU). Young adults (N=366) aged 18-26 years old were sampled in Los Angeles in 2014-15 and segmented into NPU (n=156), marijuana users who never had a medical marijuana (MM) recommendation, and MMP (n=210), marijuana users with a current, verified MM recommendation. Differences regarding self-reported marijuana and other drug use during the past 90days are expressed as unadjusted risk ratios or differences in means. MMP reported significantly greater mean days of use (76.4 vs. 59.2, p<0.001) and mean dollars spent on marijuana products (564.5 vs. 266.9, p<0.001) than NPU. Approximately one-quarter (22.6%) of both MMP and NPU report selling marijuana obtained from a dispensary to someone else in the past 90days. MMP were more likely to report vaporization modalities for concentrates (URR=1.5, 95% C.I.=1.2, 2.0) and for marijuana (URR=1.5, 95% C.I.=1.1, 2.1) than NPU. Though not significant, trends toward lower misuse of prescription drugs in the past 90days were observed among MMP compared to NPU. MMP reported greater access to marijuana via dispensaries, more frequent and intensive use of marijuana, and greater use of non-combustible forms of marijuana compared to NPU. MMP reported less recent misuse of prescription drugs compared to NPU. Copyright © 2016. Published by Elsevier Ireland Ltd.

Drug problems in contemporary China: a profile of Chinese drug users in a metropolitan area.

Drug problems are reemerging in China since the nation implemented economic reform and an "open door" policy in the early 1980s. This is causing both national and international concern. However, knowledge and understanding of the Chinese drug problem is fairly limited because of the nation's unique social and political history. In response to this shortage of information, our study presents a profile of Chinese drug users. Data were collected from a survey of drug users attending mandatory treatment centres in a large city in 2009. We present a demographic profile of the drug users, describe their patterns of drug use, their access to drugs and their history of drug treatment. Chinese drug users, like those from the U.S., are likely to be unemployed and have a low level of education. However, they are more likely than those in the U.S. to use heroin, Bingdu (methamphetamine) and Maguo (a derivative of methamphetamine), and they pay less for their drugs. This profile of drug users is informative and valuable for drug prevention, intervention, and treatment in the Chinese setting because knowing and understanding the drug population is essential for effective control.

2017-12-01

Previous studies indicate that young people who have positive attitudes towards illicit drugs are more inclined to experiment with them. The first aim of our study was to identify the sociodemographic and risk behaviour characteristics of young people (16-24 years) with positive attitudes towards illicit drug use. The second aim was to identify the characteristics of young people with positive attitudes towards illicit drugs among those who had never tried drugs, those who had tried cannabis but no other illicit drugs, and those who regularly used cannabis and/or had tried other illicit drugs. The analysis was based on a population-based survey from 2013 ( N = 3812). Multiple logistic regression was used to analyse the association between sociodemographic and risk behaviour characteristics and positive attitudes towards illicit drugs. Young men had twice the odds of having positive attitudes towards illicit drug use compared with young women (AOR = 2.1). Also, young age, being single, being employed, smoking tobacco, practising unprotected sex, and experimental cannabis use were associated with positive attitudes towards illicit drug use. Finally, use of cannabis at least 10 times during the previous year and/or use of other illicit drugs had the strongest association with positive attitudes to illicit drug use (AOR = 6.0). Young people who have positive attitudes towards illicit drug use are characterized by a broad range of risky behaviours. These findings may help to identify young people at risk of initiating illicit drug use and thereby support the development and implementation of prevention programmes.

Background Given high rates of methamphetamine (MA) use among young people in Thailand and evidence of an association between MA and increased sexual risk behavior, we examined the association between women’s recent sexual partnerships, social network characteristics and drug and alcohol use. Methods Female participants (n=320) in an HIV behavioral trial among young (18–25 years) MA users in Chiang Mai completed a drug and sexual behavior survey and social network inventory. Multinomial regression analyses accounting for clustered data examined individual and network characteristics associated with recent sexual partnership category. We compared women with only one male partner in the past year (39%) to those with multiple male partners (37%) and those with only female partners (24%). Results Differences in levels of drug and alcohol use and social and sexual network characteristics were dependent on recent sexual partnership profiles. The multiple partner group reported an average of five male partners in the past year; 12% reported consistent condom use in the past 30 days. Compared to both groups, women with multiple male partners used MA more frequently, had larger non-sex networks with more MA users, were more likely to have an MA-using sex partner, and received less emotional support from their partners. Women with multiple male partners and only female partners reported more frequent alcohol use. Conclusions Policy and intervention efforts targeting drug use and sexual behavior among young Thai women are drastically needed and may benefit from consideration of the diversity within the population. These data point to the need for targeted prevention approaches that take into account the varying characteristics and social influences of these different groups of women. PMID:18191393

Self-Esteem and HIV Risk Practices among Young Adult “Ecstasy” Users

2013-01-01

In this paper, we examine the role that self-esteem plays in HIV-related risk taking among users of the drug, ecstasy. The first part of the analysis focuses on the relationship of self-esteem to HIV risk-taking. The second part of the analysis examines predictors of self-esteem in this population. The research is based on a sample of 283 young adult ecstasy users. The study took place between August 2002 and August 2004 and entailed face-to-face interviews that were completed with the use of computer-assisted structured interviews. Study participants were recruited in the Atlanta, Georgia metropolitan area using a targeted sampling and ethnographic mapping approach. Interviews took approximately two hours to complete. Results of multivariate analyses indicated that self-esteem is associated with a variety of risky practices, including: the number of sex partners that people reported having, individuals’ likelihood of having multiple sex partners, the number of different types of illegal drugs that people reported using, and their condom use self-efficacy. The multivariate analysis conducted to ascertain the factors that impact young adult ecstasy users’ levels of self-esteem yielded six such factors: educational attainment (positive), coming from a family-of-origin whose members got along well (positive), the extent of alcohol problems experienced recently (negative), the number of positive effects experienced recently as a result of ecstasy use (positive), the number of negative effects experienced recently as a result of ecstasy use (negative), and the extent of experiencing symptoms of post-traumatic stress disorder (negative).

Riding with a drunk and/or a drugged driver (RDD) is a risk behaviour that has received very little attention in spite of its potential dangers. Young people involved in the recreational nightlife context are especially at risk. 1363 regular users of recreational nightlife from nine European countries (mean age: 21.75; 51.5% women) filled out a self-administered and anonymous questionnaire (in 2006). 37.2% had practised RDD during the previous month. RDD is related to drunkenness and use of drugs, personality factors such as impulsivity, preferring to use a private car to get to nightlife venues, living in a southern European country and being unemployed. No significant influence was found for age, gender, educational level or socioeconomic status. It is important to raise awareness about the high prevalence of RDD. This lack of awareness can be related to its social acceptance among young people. The use of private cars for going to nightlife venues should be discouraged.

While marijuana has been legal for medical purposes in California since 1996, little is known about the health histories of young adult medical marijuana patients who are a significant proportion of medical marijuana patients. We examined whether young adult medical marijuana patients reported health conditions and motivations for use that were consistent with medical use of marijuana in California. Young adults (N = 366) aged 18 to 26 years were sampled in Los Angeles in 2014-2015 and segmented into medical marijuana 'patients' (n = 210), marijuana users with a current recommendation, and non-patient users or 'non-patients' (n = 156), marijuana users who never had a medical marijuana recommendation. Differences between patients and non-patients regarding self-reported health histories and past/current motivations for marijuana use were expressed as unadjusted risk ratios. Compared with non-patients, patients were significantly more likely to report a range of lifetime health problems, such as psychological, physical pain and gastrointestinal. In the past 90 days, patients were significantly more likely to report motivations for marijuana use than non-patients concerning sleep, anxiety, physical pain and focusing. Psychological and pain problems were the most common health conditions reported to receive a medical marijuana recommendation. Patients were significantly less likely than non-patients to report any privacy concerns about obtaining a medical marijuana recommendation. Patients were significantly more likely to report a range of health conditions and motivations associated with medical use than non-patients. A great majority of patients reported obtaining a medical marijuana recommendation for health problems in accordance with the California law.

[Users sceptical about generic drugs: an anthropological approach].

Sarradon-Eck, A; Blanc, M-A; Faure, M

2007-06-01

Since the enactment of the 2002 legislative measures favoring the prescription of generic drugs, various quantitative studies have shown that approval by prescribers and users has risen in France. Nevertheless, scepticism remains as well as distrust towards these drugs focusing on their effectiveness compared with brand-name drugs, on potential dangers, and on the interruption they cause in prescription and consumption habits. Using a comprehensive approach, this article analyzes the social and cultural logic behind the negative image of generic drugs. The materials issued from an ethnographic study on the prescription of drugs for high blood pressure. Sixty-eight interviews were undertaken between April 2002 and October 2004 with people (39 women and 29 men, between the age of 40 and 95, 52 over the age of 60) treated for over a year for high blood pressure in rural areas in the Southeast of France. Thirteen people provided unsolicited opinions about generic drugs. Analysis of the information collected shows that users have various representations of generic drugs, including the idea of counterfeited and foreign drugs. These representations interfere with the adjustment process and the development of consumer loyalty. They are part of a set of social representations about drugs which form and express the user's reality. In these representations, the drug is an ambivalent object, carrier of both biological effectiveness and toxicity; it is also the metonymical extension of the prescriber, bestowing upon the prescription a symbolic value. By placing the generic drug in its network of symbolic and social meaning, this study highlights the coherence of the scepticism towards generic drugs by consumers (and prescribers) with a system of common opinion in which drugs are everyday things, personalized and compatible with users, symbolic exchange carriers in the physician-patient relationship, and in which confidence in the drug is also that given to the health care

2015-11-01

The aim of the current study was to identify and compare the characteristics of maxillofacial trauma in alcohol and drug users with those of nonusers. A retrospective study was conducted using the medical records of patients treated for facial trauma between April 1999 and March 2012 at the Maxillofacial Surgery Division of the Piracicaba Dental School. The data were analyzed by descriptive analysis, binary logistic regression, and correlational analysis using SPSS 18.0 software. The results were considered relevant at P < 0.05. Medical records of 3724 patients with facial trauma were analyzed, of which 173 were illicit drug users and 19.36% reported alcohol intake. The use of illicit drugs was reported by 4.64%. The prevalent etiological factor among drug and alcohol users was interpersonal violence. The mandible was the face part most affected by fractures. Male patients exhibited increased odds of experiencing fractures (OR = 1.43), as did users of illicit drugs (OR = 1.62), when compared with nonusers. When faced with maxillofacial trauma, male drug users exhibited an increased chance of experiencing fractures. This knowledge should be used as a baseline to implement more efficient prevention strategies for this population.

Background Perceived risk and attitudes about the consequences of drug use, perceptions of others expectations and self-efficacy influence the intent to try drugs and continue drug use once use has started. We examine associations between adolescents’ attitudes and beliefs towards ecstasy use; because most ecstasy users have a history of marijuana use, we estimate the association for three groups of adolescents: non-marijuana/ecstasy users, marijuana users (used marijuana at least once but never used ecstasy) and ecstasy users (used ecstasy at least once). Methods Data from 5,049 adolescents aged 12–18 years old who had complete weighted data information in Round 2 of the Restricted Use Files (RUF) of the National Survey of Parents and Youth (NSPY). Data were analyzed using jackknife weighted multinomial logistic regression models. Results Adolescent marijuana and ecstasy users were more likely to approve of marijuana and ecstasy use as compared to non-drug using youth. Adolescent marijuana and ecstasy users were more likely to have close friends who approved of ecstasy as compared to non-drug using youth. The magnitudes of these two associations were stronger for ecstasy use than for marijuana use in the final adjusted model. Our final adjusted model shows that approval of marijuana and ecstasy use was more strongly associated with marijuana and ecstasy use in adolescence than perceived risk in using both drugs. Conclusion Information about the risks and consequences of ecstasy use need to be presented to adolescents in order to attempt to reduce adolescents’ approval of ecstasy use as well as ecstasy experimentation.

Values and beliefs of psychedelic drug users: a cross-cultural study.

PubMed

Lerner, Michael; Lyvers, Michael

2006-06-01

Psychedelic drugs such as LSD and psilocybin are often claimed to be capable of inducing life-changing experiences described as mystical or transcendental, especially if high doses are taken. The present study examined possible enduring effects of such experiences by comparing users of psychedelic drugs (n = 88), users of nonpsychedelic illegal drugs (e.g., marijuana, amphetamines) (n = 29) and non illicit drug-using social drinkers (n = 66) on questionnaire measures of values, beliefs and emotional empathy. Samples were obtained from Israel (n = 110) and Australia (n = 73) in a cross-cultural comparison to see if values associated with psychedelic drug use transcended culture of origin. Psychedelic users scored significantly higher on mystical beliefs (e.g., oneness with God and the universe) and life values of spirituality and concern for others than the other groups, and lower on the value of financial prosperity, irrespective of culture of origin. Users of nonpsychedelic illegal drugs scored significantly lower on a measure of coping ability than both psychedelic users and non illicit drug users. Both groups of illegal drug users scored significantly higher on empathy than non illicit drug users. Results are discussed in the context of earlier findings from Pahnke (1966) and Doblin (1991) of the transformative effect of psychedelic experiences, although the possibility remains that present findings reflect predrug characteristics of those who chose to take psychedelic drugs rather than effects of the drugs themselves.

Background & objectives: Evidence has suggested that parenting styles have peculiar characteristics in families with drug-related issues. This study was undertaken to investigate the perception of crack (smoke cocaine) users and non-users about parental bonding quality regarding care and control in Brazil. Methods: A total of 198 hospitalized crack users and 104 users of any non-illicit drug were assessed using the Parental Bonding Instrument (PBI), the sixth version of the Addiction Severity Index (ASI) and Mini International Neuropsychiatric Interview (MINI). Results: Adjusted logistic regression analysis showed that crack users were more likely (ORadj = 9.68; 95% CI: 2.82, 33.20) to perceive neglectful mothers, as well as more likely (ORadj = 4.71, 95% CI: 2.17, 10.22) to perceive controlling and affectionless fathers in comparison with non-illicit drug users who were more likely to perceive optimal parenting. Interpretation & conclusions: Our findings indicate that the perception of neglectful mothers and affectionless controlling fathers may be associated with the tendency of the children to be less resilient when facing stressful events, leading them to a greater risk to use crack.

We report the results of qualitative (n=19) and quantitative (n=545) interviews with young injection drug users (IDUs) in San Diego, California, USA about their experiences using drugs in Tijuana, Mexico, and associated risks for HIV infection. Young IDUs who have ever traveled to Mexico (n=365) used a variety of injection (54%) and non-injection (30%) drugs there, and appear to be heavier users than those who have never traveled to Mexico. Sociocultural themes influencing drug use in Mexico included: interactions amongst the purpose of travel, drug preference, and route of administration; familiarity with the border region; evolving relationships with the US and Mexican drug markets; and the experience of crossing the US/Mexico border. Interventions for IDUs in border regions need to be sensitive to the ethnicity, familiarity with the border region, and life history of participants, as well as differences in national policies that could influence drug use and risk for HIV on both sides of the border.

High risk and little knowledge: Overdose experiences and knowledge among young adult nonmedical prescription opioid users

2014-01-01

Background Opioid-involved overdoses in the United States have dramatically increased in the last 15 years, largely due to a rise in prescription opioid (PO) use. Yet few studies have examined the overdose knowledge and experience of nonmedical PO users. Methods In depth, semi-structured, audio-recorded interviews were conducted with 46 New York City young adults (ages 18–32) who reported using POs nonmedically within the past 30 days. Verbatim interview transcripts were coded for key themes in an analytic process informed by grounded theory. Results Despite significant experience with overdose (including overdose deaths), either personally or within opioid-using networks, participants were relatively uninformed about overdose awareness, avoidance and response strategies, in particular the use of naloxone. Overdose experiences typically occurred when multiple pharmaceuticals were used (often in combination with alcohol) or after participants had transitioned to heroin injection. Participants tended to see themselves as distinct from traditional heroin users, and were often outside of the networks reached by traditional opioid safety/overdose prevention services. Consequently, they were unlikely to utilize harm reduction services, such as syringe exchange programs (SEPs), that address drug users' health and safety. Conclusions These findings suggest that many young adult nonmedical PO users are at high risk of both fatal and non-fatal overdose. There is a pressing need to develop innovative outreach strategies and overdose prevention programs to better reach and serve young PO users and their network contacts. Prevention efforts addressing risk for accidental overdose, including opioid safety/overdose reversal education and naloxone distribution, should be tailored for and targeted to this vulnerable group.

Objective The purpose of this study was to evaluate the perinatal outcomes in pregnant women who use illicit drugs. Methods A retrospective observational study of patients who, at the time of delivery, were sent to or who spontaneously sought a public maternity hospital in the eastern area of São Paulo city. We compared the perinatal outcomes of two distinct groups of pregnant women - illicit drugs users and non-users - that gave birth in the same period and analyzed the obstetric and neonatal variables. We used Student's t-test to calculate the averages among the groups, and the Chi-square test or Fisher's exact test to compare categorical data from each group. Results We analyzed 166 women (83 users and 83 non-users) in both groups with a mean of age of 26 years. Ninety-five percent of the drug users would use crack or pure cocaine alone or associated with other psychoactive substances during pregnancy. Approximately half of the users group made no prenatal visit, compared with 2.4% in the non-users group (p < 0.001). Low birth weight (2,620 g versus 3,333 g on average, p < 0.001) and maternal syphilis (15.7% versus 0%, p < 0.001) were associated with the use of these illicit drugs. Conclusions The use of illicit drugs, mainly crack cocaine, represents an important perinatal risk. Any medical intervention in this population should combine adherence to prenatal care with strategies for reducing maternal exposure to illicit drugs. Thieme Publicações Ltda Rio de Janeiro, Brazil.

The objective of this article is to analyse the opinions of adolescents and young people, from gypsy and non-gypsy populations, on the relationship between recreational drug use and sexual practices that increase the risk of HIV infection. A descriptive qualitative research was undertaken. 14 focus groups were conducted with 98 adolescents and young people, and 7 semi-structured interviews with young recreational drug users. Both sort of results were triangulated. Two major discursive lines emerge in the analysis. The first one defends the notion that moderate consumption of alcohol facilitates the sexual encounter, but it does not imply risky behaviours. However, polydrug use or an elevated use of recreational drugs is related to a lack of concern for sexual risks, and in men with the loss of sexual sensitivity that sometimes justifies not using a condom. The second line argues other reasons for the non-use of condoms, such as their lack of availability, confidence in one's sexual partner, a concept of desire as something uncontrollable, infatuation and the state of mind or self-esteem. Some recommendations to prevent sexual transmission of HIV are derived from the results, such as the distribution of condoms in places where alcohol and other drugs are consumed, publicising the use of condoms and other latex barriers for oral genital sexual practices, working with young males on the optimisation of pleasure, designing preventive interventions targeting stable partners, and training adolescent girls in the social skills needed to negotiate the use of condoms.

A TYPOLOGY OF DRUG-RELATED OFFENDING AMONG YOUNG HOMELESS INJECTION DRUG USERS

PubMed Central

Sanders, Bill; Lankenau, Stephen E.; Jackson Bloom, Jennifer; Hathaz, Dodi S.

2011-01-01

Research indicates a link between drug use and offending, particularly amongst high-risk individuals, such as homeless youth. The extent to which such youth interpret their offending as being related to their drug use, though, is understudied. This manuscript investigates the interpretations of drug-related offenses offered by 151 primarily white, male, homeless IDUs aged 16–29 years. Youth were asked specific questions about their drug-related offenses during in-depth interviews as part of a larger study investigating health risks surrounding drug injection between 2004 and 2006. The first section of the manuscript outlines offenses youth revealed committing either in pursuit of or after using a variety of substances. The second part of the manuscript examines the overall context (motivation, environment), and provides a seven-tiered typology of drug-related offending based on youth's interpretations, linking certain drugs to specific offenses within particular contexts. From here, some theoretical and practical implications of the findings are discussed. PMID:21423855

Benzodiazepine Dependence among Young Adult Participants in the Club Scene Who Use Drugs.

2017-01-01

Young adults ages 18-29 report the highest rates of benzodiazepine (BZD) misuse in the United States. The majority of club drug users are also in this age group, and BZD misuse is prevalent among participants in club scenes. This article examines BZD dependence and its correlates among young adult participants in the electronic dance music (EDM) culture in Miami, Florida, who use drugs. Structured interviews were with men and women (N = 356) ages 18 to 29 who reported regular attendance at EDM venues and recent use of both club drugs and BZDs. Prevalences of BZD-related problems were 12.6% for BZD dependence, 21.1% BZD abuse, and 24.2% BZD abuse and/or dependence. In a multivariate logistic regression model, younger age (OR 0.85; 95% CI 0.76, 0.96), severe mental distress (OR 8.30; 95% CI 3.07, 22.49), daily marijuana use (OR 2.10; 95% CI 1.03, 4.27), and heavy opioid use (OR 2.33; 95% CI 1.12, 4.83) were associated with BZD dependence. BZD dependence was higher in this sample than in other populations described in the literature. The links between BZD dependence, overdose history, and heavy opioid misuse are especially worrisome among this young sample. Recommendations for intervention and research are discussed.

It discusses the opportunities and challenges that these organizations face in their search for legitimacy and political influence. The comparative perspective points at similarities and differences in national contexts that both support and challenges the existence of drug user organizations, including drug policy, social welfare policy, trends in drug use, and organizational conditions. The article also discusses the importance of international network and transnational organizations that support drug user organizations.

Drug users in contact with general practice.

Robertson, J R

1985-01-05

A group of heroin users who are in contact with a general practice in north west Edinburgh are described. The study group was younger and included more women than previous studies. These people used a large variety of drugs and mainly purchased them locally. Frequent and often prolonged abstinent periods occurred with no prescribed opiate treatment. The group had experienced a high rate of drug related medical disorders. All these points raise the possibility that opiate users who are known to general practitioners may be a distinctly different population from those who attend drug dependency clinics. The frequency of remission and the prevalence of polydrug use have profound implications for planning and evaluating an effective medical response.

Background While a significant minority of prescription drug misusers report purchasing prescription drugs, little is known about prescription drug selling. We build upon past research on illicit drug markets, which increasingly recognizes networks and nightlife as influential, by examining prescription drug market involvement. Methods We use data from 404 young adult prescription drug misusers sampled from nightlife scenes. Using logistic regression, we examine recent selling of and being approached to sell prescription drugs, predicted using demographics, misuse, prescription access, and nightlife scene involvement. Results Those from the wealthiest parental class and heterosexuals had higher odds (OR=6.8) of selling. Higher sedative and stimulant misuse (ORs=1.03), having a stimulant prescription (OR=4.14), and having sold other illegal drugs (OR=6.73) increased the odds of selling. College bar scene involvement increased the odds of selling (OR=2.73) and being approached to sell (OR=2.09). Males (OR=1.93), stimulant users (OR=1.03), and sedative prescription holders (OR=2.11) had higher odds of being approached. Discussion College bar scene involvement was the only site associated with selling and being approached; such participation may provide a network for prescription drug markets. There were also differences between actual selling and being approached. Males were more likely to be approached, but not more likely to sell than females, while the opposite held for those in the wealthiest parental class relative to lower socioeconomic statuses. Given that misuse and prescriptions of sedatives and stimulants were associated with prescription drug market involvement, painkiller misusers may be less likely to sell their drugs given the associated physiological dependence.

Are drug treatment services only for 'thieving junkie scumbags'? Drug users and the management of stigmatised identities.

PubMed

Radcliffe, Polly; Stevens, Alex

2008-10-01

This article uses qualitative interviews with 53 problematic drug users who had dropped out of treatment in England, UK to explore how they describe the stigmatisation of drug users and drug services. It discusses the construction of the category of the junkie through its association with un-controlled heroin use and criminality. It shows how some drug users carefully manage information about their discreditable identities by excluding themselves from this category, while acknowledging its validity for other drug users. The junkie identity was generally seen as shameful and therefore to be avoided, although it holds attractions for some drug users. For many of the interviewees, entry to treatment risked exposing their own activities as shaming, as they saw treatment as being a place that was populated by junkies and where it becomes more difficult to manage discreditable information. The treatment regime, e.g. the routine of supervised consumption of methadone, was itself seen by some as stigmatising and was also seen as hindering progress to the desired 'normal' life of conventional employment. Participation in the community of users of both drugs and drug services was perceived as potentially damaging to the prospects of recovery. This emphasises the importance of social capital, including links to people and opportunities outside the drug market. It also highlights the danger that using the criminal justice system to concentrate prolific offenders in treatment may have the perverse effects of excluding other people who have drug problems and of prolonging the performance of the junkie identity within treatment services. It is concluded that treatment agencies should address these issues, including through the provision of more drug services in mainstream settings, in order to ensure that drug services are not seen to be suitable only for one particularly stigmatised category of drug user.

Other drug use does not impact cognitive impairments in chronic ketamine users.

Ketamine abuse causes cognitive impairments, which negatively impact on users' abstinence, prognosis, and quality of life. of cognitive impairments in chronic ketamine users have been inconsistent across studies, possibly due to the small sample sizes and the confounding effects of concomitant use of other illicit drugs. This study investigated the cognitive impairment and its related factors in chronic ketamine users with a large sample size and explored the impact of another drug use on cognitive functions. Cognitive functions, including working, verbal and visual memory and executive functions were assessed in ketamine users: 286 non-heavy other drug users and 279 heavy other drug users, and 261 healthy controls. Correlations between cognitive impairment and patterns of ketamine use were analysed. Verbal and visual memory were impaired, but working memory and executive functions were intact for all ketamine users. No significant cognitive differences were found between the two ketamine groups. Greater number of days of ketamine use in the past month was associated with worse visual memory performance in non-heavy other drug users. Higher dose of ketamine use was associated with worse short-term verbal memory in heavy other drug users. Verbal and visual memory are impaired in chronic ketamine users. Other drug use appears to have no impact on ketamine users' cognitive performance. Copyright © 2018. Published by Elsevier B.V.

Young adults as users of adult healthcare: experiences of young adults with complex or life-limiting conditions.

Beresford, B; Stuttard, L

2014-08-01

Awareness is growing that young adults may have distinctive experiences of adult healthcare and that their needs may differ from those of other adult users. In addition, the role of adult health teams in supporting positive transitions from paediatrics is increasingly under discussion. This paper contributes to these debates. It reports a qualitative study of the experiences of young adults - all with complex chronic health conditions - as users of adult health services. Key findings from the study are reported, including an exploration of factors that help to explain interviewees' experiences. Study findings are discussed in the context of existing evidence from young adults in adult healthcare settings and theories of 'young adulthood'. Implications for training and practice are considered, and priorities for future research are identified. © 2014 Royal College of Physicians.

Characterization of Young Adult Emergency Department Users: Evidence to Guide Policy.

2016-12-01

The purpose of this study was to characterize young adult patients aged 19-25 years who are emergency department (ED) frequent users and study factors associated with frequent ED use. ED visits among 19- to 25-year olds were identified from administrative records in California, Florida, Iowa, Massachusetts, and New York, 2010. Patients were analyzed for 12 months to study the frequency of their ED utilization. ED visits were categorized according to primary diagnosis. Patients were stratified by frequency of ED use: one visit (single users), two to four visits (infrequent users), and five or more visits (frequent users) in a 1-year period. We identified 1,711,774 young adult patients who made 3,650,966 ED visits. Sixty-six percent of patients were single users, 29% were infrequent users, and 4.6% were frequent users. Frequent users accounted for a disproportionate 28.8% of visits within the population studied. Frequent users had the largest proportion of visits for complications of pregnancy (13.6%) compared to single users (6.1%) and Medicaid (42.6%) compared to private insurance (17.3%). There was an increased risk of frequent ED use associated with females (odds ratio [OR]: 1.77), Medicaid (OR: 3.21), and Medicare insurance (OR: 4.22) compared to private insurance, and diseases of the blood (OR: 3.36) and mental illness (OR: 1.99) compared to injury and poisoning. Frequent users comprise a significant portion of the young adult ED population and present with a large proportion of visits for complications of pregnancy. Policies targeting this population might focus on improved access to primary and urgent care, acute obstetric care, and better coordination of care.

This article reviews published 16PF research on drug users. It also compares the 16PF scores of a new sample of nonusers with scores of matched groups of heavy, chronic users of cocaine, amphetamine, opiates, and barbiturates/sedative hypnotics, as well as combined groups of stimulant users, depressant users, and a combined group of users of all substances. No significant differences were found among drug user groups, but the profile of the nonuser group was distinctive. K-Means Cluster Analyses, as well as Cattell's Similarity and Pearson Product Moment Correlation Coefficients, were used to compare profiles of these new samples with the 19 groups described in an earlier meta-analysis of published 16PF studies. Data from the new samples did not cluster with data from other published research, although certain specific similarities appeared in more detailed correlational analyses. Methodological problems are discussed, and it is recommended that in future studies drug user groups be more carefully selected and defined, sample descriptions be more thorough and complete, complete profile information be routinely provided, and efforts be made to explore the utility of the Cattell CAQ in studies of drug users/misusers.

Aim In light of the resurgence in MDMA use and its association with polysubstance use, we investigated the 12-month prevalence of substance use disorders (SUDs) among adult MDMA users to determine whether they are at risk of other drug-related problems that would call for targeted interventions. Methods Data were drawn from the 2006 National Survey on Drug Use and Health. Past-year adult drug users were grouped into three mutually exclusive categories: 1) recent MDMA users, who had used the drug within the past year; 2) former MDMA users, who had a history of using this drug but had not done so within the past year; and 3) other drug users, who had never used MDMA. Logistic regression procedures were used to estimate the association between respondents’ SUDs and MDMA use while adjusting for their socioeconomic status, mental health, age of first use, and history of polydrug use. Results Approximately 14% of adults reported drug use in the past year, and 24% of those past-year drug users reported a history of MDMA use. Recent MDMA users exhibited the highest prevalence of disorders related to alcohol (41%), marijuana (30%), cocaine (10%), pain reliever/opioid (8%), and tranquilizer (3%) use. Adjusted logistic regression analyses revealed that, relative to other drug users, those who had recently used MDMA were twice as likely to meet criteria for marijuana and pain reliever/opioid use disorders. They were also about twice as likely as former MDMA users to meet criteria for marijuana, cocaine, and tranquilizer use disorders. Conclusions Seven out of ten recent MDMA users report experiencing an SUD in the past year. Adults who have recently used MDMA should be screened for possible SUDs to ensure early detection and treatment. PMID:19361931

Similarity and Difference in Drug Addiction Process Between Heroin- and Methamphetamine-Dependent Users.

Wang, Ziyun; Li, Wei-Xiu; Zhi-Min, Liu

2017-03-21

This study aimed to compare the drug addiction process between Chinese heroin- and methamphetamine (MA)-dependent users via a modified 4-stage addiction model (experimentation, occasional use, regular use, and compulsive use). A descriptive study was conducted among 683 eligible participants. In the statistical analysis, we selected 340 heroin- and 295 MA-dependent users without illicit drug use prior to onset of heroin or MA use. The addiction process of heroin-dependent users was shorter than that of MA-dependent users, with shorter transitions from the onset of drug-use to the first drug craving (19.5 vs. 50.0 days), regular use (30.0 vs. 60.0 days), and compulsive use (50.0 vs. 85.0 days). However, no significant differences in the addiction process were observed in frequency of drug administration, except that heroin users reported more administrations of the drug (20.0 vs. 15.0) before progressing to the stage of compulsive drug use. A larger proportion of regular heroin users progressed to use illicit drugs recklessly than did MA users. Most heroin and MA users reported psychological dependence as their primary motivation for compulsive drug use, but more heroin users selected uncomfortable symptoms upon ceasing drug use as further reason to continue. Our results suggest that typical heroin and MA users may experience a similar four-stage addiction process, but MA users might undergo a longer addiction process (in days). More research is necessary to further explore factors influencing the drug addiction process.

Impaired cognitive performance in drug free users of recreational ecstasy (MDMA)

OBJECTIVES—Ecstasy (3,4-methylenedioxymethamphetamine (MDMA) and related congerers: MDA, MDEA) is the name given to a group of popular recreational drugs. Animal data raise concern about neurotoxic effects of high doses of ecstasy on central serotonergic systems. The threshold dose for neurotoxicity in humans is not clear and serotonin is involved in several functions including cognition. The purpose of this study was to investigate cognitive performance in a group of typical recreational ecstasy users.
METHODS—A comprehensive cognitive test battery was administered to 28 abstinent ecstasy users with concomitant use of cannabis only and to two equally sized matched groups of cannabis users and non-users. The sample consisted of ecstasy users with a typical recreational use pattern and did not include very heavy users.
RESULTS—Ecstasy users were unimpaired in simple tests of attention (alertness). However, they performed worse than one or both control groups in the more complex tests of attention, in memory and learning tasks, and in tasks reflecting aspects of general intelligence. Heavier ecstasy and heavier cannabis use were associated with poorer performance in the group of ecstasy users. By contrast, the cannabis users did not differ significantly in their performance from the non-users.
CONCLUSIONS—The present data raise concern that use of ecstasy possibly in conjunction with cannabis may lead to cognitive decline in otherwise healthy young people. Although the nature of the emerging cognitive disturbance is not yet clear, an impairment of working memory might be the common denominator underlying or contributing to declines of performance in various tasks. The cognitive disturbance is likely to be related to the well recognised neurotoxic potential of ecstasy. The data suggest that even typical recreational doses of ecstasy are sufficient to cause neurotoxicity in humans.

Background International borders are unique social and environmental contexts characterized by high levels of mobility. Among drug users, mobility increases risk for human immunodeficiency virus (HIV) in part through its effects on the social environment. However, the social dynamics of drug users living in border regions are understudied. Methods 1056 injection drug users (IDUs) residing in Tijuana, Mexico were recruited using respondent-driven sampling (RDS) from 2006 to 2007, and underwent surveys and testing for HIV, syphilis, and tuberculosis (TB). Using logistic regression on baseline data, we identified correlates of having ever injected drugs with someone from the US. Results Almost half (48%) reported ever injecting drugs with someone from the US. In RDS-adjusted logistic regression, factors independently associated with having ever injected with someone from the US included: having greater than middle school education (Adjusted Odds Ratio [AOR] 2.91; 95% Confidence Interval [C.I.] 1.52, 5.91), speaking English (AOR 3.24, 95% C.I. 1.96, 5.36), age (AOR 1.10 per year; 95% C.I. 1.07, 1.14), age at initiation of injection drug use (AOR 0.90 per year; 95% C.I. 0.86, 0.94), homelessness (AOR 2.61; 95% C.I. 1.27, 5.39), and having ever been incarcerated (AOR 11.82; 95% C.I., 5.22, 26.77). No associations with HIV, syphilis, TB, drug use, or injection risk behavior were detected. Conclusion Findings suggest that IDU networks in Mexico and the US may transcend international borders, with implications for cross-border transmission of infectious disease. Binational programs and policies need to consider the structure and geographic distribution of drug using networks. PMID:20889270

2015-01-01

Relapse is a common problem in drug user's rehabilitation program and reported in all over the country. An in-depth study on patients' experiences can be used for exploring the relapse process among drug users. Therefore, this study suggests a model for relapse process among Iranian drug users. In this qualitative study with grounded theory approach, 22 participants with rich information about the phenomenon under the study were selected using purposive, snowball and theoretical sampling methods. After obtaining the informed consent, data were collected based on face-to-face, in-depth, semi-structured interviews. All interviews were analyzed in three stages of axial, selective and open coding methods. Nine main categories emerged, including avoiding of drugs, concerns about being accepted, family atmosphere, social conditions, mental challenge, self-management, self-deception, use and remorse and a main category, feeling of loss as the core variable. Mental challenge has two subcategories, evoking pleasure and craving. Relapse model is a dynamic and systematic process including from cycles of drug avoidance to remorse with a core variable as feeling of loss.  Relapse process is a dynamic and systematic process that needs an effective control. Determining a relapse model as a clear process could be helpful in clinical sessions. RESULTS of this research have depicted relapse process among Iranian drugs user by conceptual model.

This paper describes findings from a study of young men who have sex with men (YMSM) in New York City. Using a cross-sectional design and a community-based targeted sampling approach, a total of 569 YMSM were recruited during 2000 and 2001 for a structured survey interview. High rates of lifetime exposure to a variety of club drugs (including methamphetamine, ketamine, and MDMA) are observed in the overall sample. Among those who use club drugs on a chronic basis (N=145), we found high rates of a prior suicide attempt (including high rates of multiple suicide attempts), high rates of lifetime exposure to multiple types of drugs, high rates of current poly drug use (including multiple types of club drugs), and high rates of current depressive symptoms. Chronic club drug users had a mean CES-D score of 8.5 and nearly two-thirds had a score of 7 or more. Although high rates of condom use are reported in some types of sexual exchanges, data show multiple types of sexual risk among chronic club drug users, including high rates of unprotected anal intercourse (UAI) with most frequent partners and comorbid drug use among both YMSM and their sexual partners.

Use of Protective Behavioral Strategies among Young Adult Veteran Marijuana Users.

PubMed

Pedersen, Eric R; Villarosa-Hurlocker, Margo C; Prince, Mark A

2018-01-01

Young adult veterans are at risk for problematic marijuana use and associated consequences, which is partially due to their high rates of Posttraumatic Stress Disorder (PTSD), depression, and problematic substance use. Veterans tend to endorse more severe and chronic mental health symptoms compared to their civilian counterparts and they identify marijuana use as a method to cope with their symptoms. Given the prevalence of marijuana use among veterans in the community and in clinical settings, it is important to explore the factors that may help minimize harm associated with use for those that choose to use the drug. The present study sought to examine the impact of protective behavioral strategies on the relationship between mental health symptoms and marijuana use and consequences in a sample of 180 young adult veteran marijuana users. Participants were recruited via social media advertisements and completed measures of marijuana use and consequences, protective behavioral strategies, and PTSD and depression symptoms. Findings indicated that more frequent use of protective behavioral strategies was associated with less marijuana use and consequences. Participants who screened positive for PTSD or depression reported more marijuana consequences than did those not positive on these screeners. Regression analyses revealed protective strategies moderated the relationship between PTSD and marijuana consequences such that young veterans who endorsed more PTSD symptoms and infrequent use of protective strategies reported the most marijuana consequences. No moderating effects were found for the relationship between depression and marijuana consequences. Findings have clinical implications for working with young veterans.

How do drug users define their progress in harm reduction programs? Qualitative research to develop user-generated outcomes

Ruefli, Terry; Rogers, Susan J

2004-01-01

Background Harm reduction is a relatively new and controversial model for treating drug users, with little formal research on its operation and effectiveness. In order to advance the study of harm reduction programs and our understanding of how drug users define their progress, qualitative research was conducted to develop outcomes of harm reduction programming that are culturally relevant, incremental, (i.e., capable of measuring change), and hierarchical (i.e., capable of showing how clients improve over time). Methods The study used nominal group technique (NGT) to develop the outcomes (phase 1) and focus group interviews to help validate the findings (phase 2). Study participants were recruited from a large harm-reduction program in New York City and involved approximately 120 clients in 10 groups in phase 1 and 120 clients in 10 focus groups in phase 2. Results Outcomes of 10 life areas important to drug users were developed that included between 10 to 15 incremental measures per outcome. The outcomes included ways of 1) making money; 2) getting something good to eat; 3) being housed/homeless; 4) relating to families; 5) getting needed programs/benefits/services; 6) handling health problems; 7) handling negative emotions; 8) handling legal problems; 9) improving oneself; and 10) handling drug-use problems. Findings also provided insights into drug users' lives and values, as well as a window into understanding how this population envisions a better quality of life. Results challenged traditional ways of measuring drug users based solely on quantity used and frequency of use. They suggest that more appropriate measures are based on the extent to which drug users organize their lives around drug use and how much drug use is integrated into their lives and negatively impacts other aspects of their lives. Conclusions Harm reduction and other programs serving active drug users and other marginalized people should not rely on institutionalized, provider

The generic drug user fee amendments: an economic perspective

PubMed Central

Berndt, Ernst R; Murphy, Stephen J

2018-01-01

Abstract Since the vast majority of prescription drugs consumed by Americans are off patent (‘generic’), their regulation and supply is of wide interest. We describe events leading up to the US Congress's 2012 passage of the Generic Drug User Fee Amendments (GDUFA I) as part of the Food and Drug Administration Safety and Innovation Act (FDASIA). Under GDUFA I, generic manufacturers agreed to pay approximately $300 million in fees each year of the five-year program. In exchange, the US Food and Drug Administration (FDA) committed to performance goals. We describe GDUFA I’s FDA commitments, provisions, goals, and annual fee structure and compare it to that entailed in the authorization and implementation of GDUFA II on October 1, 2017. We explain how user fees required under GDUFA I erected barriers to entry and created scale and scope economies for incumbent manufacturers. Congress changed user fees under GDUFA II in part to lessen these incentives. In order to initiate and sustain user fees under GDUFA legislation, FDA requires the submission of self-reported data on generic manufacturers including domestic and foreign facilities. These data are public and our examination of them provides an unprecedented window into the recent organization of generic drug manufacturers supplying the US market. Our results suggest that generic drug manufacturing is increasingly concentrated and foreign. We discuss the implications of this observed market structure for GDUFA II’s implementation among other outcomes. PMID:29707218

2016-02-01

The nonmedical use of prescription drugs is a widely recognized public health issue, and young adults are particularly vulnerable to their use. Behavioral economic drug purchase tasks capture an individual's strength of desire and motivation for a particular drug. We examined young adult prescription drug purchase and consumption patterns using hypothetical behavioral economic purchase tasks for prescription sedatives/tranquilizers, stimulants, and opiate pain relievers. We also examined relations between demand, use frequency, and Diagnostic and Statistical Manual of Mental Disorders (5th ed.; DSM-5) substance use disorder (SUD) symptoms, and sex differences in these relations. Undergraduate students who endorsed past-year prescription drug use (N = 393) completed an online questionnaire for course credit. Measures assessed substance use frequency and DSM-5 SUD symptoms. Hypothetical purchase tasks for sedatives, stimulants, and pain relievers assessed participants' consumption and expenditure patterns for these substances across 25 prices. Past-year prescription sedative, stimulant, and pain reliever use was endorsed by 138, 258, and 189 participants, respectively. Among these users, consumption for their respective substance decreased as a function of ascending price, as expected. Demand indices for a prescription drug were associated with each other and with use frequency and SUD symptoms, with variability across substances but largely not by sex. In addition, demand for prescription pain relievers differentially predicted symptoms independent of use, with differences for females and males. In conclusion, hypothetical consumption and expenditure patterns for prescription drugs were generally well described by behavioral economic demand curves, and the observed associations with use and SUD symptoms provide support for the utility of prescription drug purchase tasks.

Kelly, Brian C; Liu, Tieqiao; Zhang, Guanbai; Hao, Wei; Wang, Jichuan

2014-01-01

Although substance abuse treatment has been considerably scaled up in China, impediments to accessing these services remain among drug users. The authors examine the primary psychosocial barriers to drug treatment in this population and evaluate factors associated with these barriers. Barriers to accessing drug treatment were measured using the Barriers to Treatment Inventory (BTI). A Structural Equation Model was used to examine whether the internal barriers were associated with treatment history and frequent methamphetamine use as well as how demographic characteristics influence such barriers. We found four primary factors of internal barriers to drug treatment – absence of problem, negative social support, fear of treatment, and privacy concerns – to fit well. Demographic factors, notably age and employment status, indirectly influence barriers to treatment via other factors. Frequency of methamphetamine use and drug treatment history are directly associated with the absence of problem and negative social support dimensions of the BTI, and it is through these pathways that demographic factors such as age and employment status shape barriers to treatment. The findings indicate that perceived absence of a problem and negative social support are the barriers most influenced by the personal domains of Chinese drug users’ lives. Efforts to engage drug users in China about drug treatment options may consider how these barriers are differentially perceived in order to effectively reach this population. PMID:24813554

The purpose of this study is to investigate how the use of flavored e-cigarettes varies between youth (12-17 years old), young adults (18-29 years old), and older adults (30 + years old). Cross-sectional surveys of school-going youth ( n  = 3907) and young adult college students ( n  = 5482) in Texas, and young adults and older adults ( n  = 6051) nationwide were administered in 2014-2015. Proportions and 95% confidence intervals were used to describe the percentage of e-cigarette use at initiation and in the past 30 days that was flavored, among current e-cigarette users. Chi-square tests were applied to examine differences by combustible tobacco product use and demographic factors. Most e-cigarette users said their first and "usual" e-cigarettes were flavored. At initiation, the majority of Texas school-going youth (98%), Texas young adult college students (95%), and young adults (71.2%) nationwide said their first e-cigarettes were flavored to taste like something other than tobacco, compared to 44.1% of older adults nationwide. Fruit and candy flavors predominated for all groups; and, for youth, flavors were an especially salient reason to use e-cigarettes. Among adults, the use of tobacco flavor at initiation was common among dual users (e-cigarettes + combustible tobacco), while other flavors were more common among former cigarette smokers (P = 0.03). Restricting the range of e-cigarette flavors (e.g., eliminating sweet flavors, like fruit and candy) may benefit youth and young adult prevention efforts. However, it is unclear what impact this change would have on adult smoking cessation.

OBJECTIVES: This study evaluated the usefulness of vending machines in providing injection drug users with access to sterile syringes in Marseille, France. METHODS: Self-administered questionnaires were offered to 485 injection drug users obtaining syringes from 32 pharmacies, 4 needle exchange programs, and 3 vending machines. RESULTS: Of the 343 respondents (response rate = 70.7%), 21.3% used the vending machines as their primary source of syringes. Primary users of vending machines were more likely than primary users of other sources to be younger than 30 years, to report no history of drug maintenance treatment, and to report no sharing of needles or injection paraphernalia. CONCLUSIONS: Vending machines may be an appropriate strategy for providing access to syringes for younger injection drug users, who have typically avoided needle exchange programs and pharmacies.

The objective of this study was to monitor the trend of addiction drug use and its relationship with sexually transmitted infections (STIs) among female drug users (FDUs). Serial cross-sectional surveys were conducted during 2010-2014 among FDUs in Beijing to collect information on addiction drug usage, sexual behaviors, and STI prevalence. Characteristics were analyzed and compared between traditional and synthetic drug users among FDUs by logistic regression method. A total of 3859 FDUs were surveyed during 2010-2014, with the median age being 32.7 years old. The proportion of synthetic drug users among FDUs increased from 43.7% in 2010 to 70.7% in 2014. Compared with traditional drug users, synthetic drug users were younger (P < 0.001), lacked education (P < 0.001), were unmarried (P < 0.001), and were non-local residents (P < 0.001). No significant difference was found with condom usage during sexual activity between traditional and synthetic drug FDUs. However, the engagement of commercial sexual activities (P < 0.001) and syphilis prevalence (P < 0.001) among synthetic drug users were significantly higher than traditional drug users. Synthetic drug abuse appears to be correlated with commercial sex behavior and higher syphilis prevalence among FDUs. Tailored strategies on health education to curb the prevalence of synthetic drug abuse are urgently needed in Beijing.

Current research shows that overall numbers for cannabis use among adolescents and young adults dropped in recent years. However, this trend is much less pronounced in continuous cannabis use. With regard to the heightened risk for detrimental health- and development-related outcomes, adolescents and young adults with continuous cannabis use need special attention. The health services structure for adolescents and young adults with substance related problems in Germany, is multifaceted, because different communal, medical and judicial agencies are involved. This results in a rather decentralized organizational structure of the help system. This and further system-inherent characteristics make the threshold for young cannabis users rather high. Because of this, there is a need to establish evidence-based low-threshold help options for young cannabis users, which can be easily disseminated. Therefore, a training programme for young cannabis users (age 14-21) was developed in the "CAN Stop" project. Within the project, we seek to implement and evaluate the training programme within different institutions of the help system. The evaluation is sensitive to the different help systems and their specific prerequisites. Moreover, within this study, we also test the practicability of a training provision through laypersons. The CAN Stop study is a four-armed randomized wait-list controlled trial. The four arms are needed for the different help system settings, in which the CAN Stop training programme is evaluated: (a) the drug addiction aid and youth welfare system, (b) the out-patient medical system, (c) the in-patient medical system and (d) prisons for juvenile offenders.

Background Current research shows that overall numbers for cannabis use among adolescents and young adults dropped in recent years. However, this trend is much less pronounced in continuous cannabis use. With regard to the heightened risk for detrimental health- and development-related outcomes, adolescents and young adults with continuous cannabis use need special attention. The health services structure for adolescents and young adults with substance related problems in Germany, is multifaceted, because different communal, medical and judicial agencies are involved. This results in a rather decentralized organizational structure of the help system. This and further system-inherent characteristics make the threshold for young cannabis users rather high. Because of this, there is a need to establish evidence-based low-threshold help options for young cannabis users, which can be easily disseminated. Therefore, a training programme for young cannabis users (age 14-21) was developed in the "CAN Stop" project. Within the project, we seek to implement and evaluate the training programme within different institutions of the help system. The evaluation is sensitive to the different help systems and their specific prerequisites. Moreover, within this study, we also test the practicability of a training provision through laypersons. Methods/Design The CAN Stop study is a four-armed randomized wait-list controlled trial. The four arms are needed for the different help system settings, in which the CAN Stop training programme is evaluated: (a) the drug addiction aid and youth welfare system, (b) the out-patient medical system, (c) the in-patient medical system and (d) prisons for juvenile offenders. Data are collected at three points, before and after the training or a treatment as usual, and six months after the end of either intervention. Discussion The CAN Stop study is expected to provide an evidence-based programme for young cannabis users seeking to reduce or quit

HIV/AIDS and iv drug use (IVDU) are of significant multinational scope and growing. Supporting increased IVDU in many countries are countries' geographical proximity to illicit drug trafficking distribution routes, law enforcement efforts which increase the demand for more efficient drug distribution and consumption, and countries' infrastructural and social modernization. Given the failures of intensified law enforcement efforts to thwart the use and proliferation of illegal drugs, countries with substantial IVDU should look away from preventing use to preventing HIV transmission within drug user populations. With HIV seroprevalence rates rapidly reaching 40-50% in some developing country IVDU groups, a variety of prevention programs is warranted. Such programs should be supported and implemented while prevention remains feasible. This paper examines the variation in HIV seroprevalence among IVD users, rapid HIV spread among users, HIV among IVDUs in Bangkok, emerging issues in HIV transmission among IVDUs, non-AIDS manifestations of HIV infection among IVDUs, prevention programs and effectiveness, and harm reduction.

To characterize the circumstances surrounding initiation of injecting drug use, data were collected from 229 young, recently initiated injection drug users enrolled through community-based recruitment in Baltimore, Maryland. Gender differences in the pattern of initiation, the number of persons present at initiation, risky injection, and sexual behaviors at initiation, as well as behaviors after initiation, were examined. Overall, men and women were similar statistically with respect to age at initiation (19.5 years) and risk behaviors at initiation. While men were initiated by men (77%), women were more often initiated by women (65%), most of whom were friends (75%) or relatives (23%). The percentage of women infected with human immunodeficiency virus (HIV) was slightly greater than that of men, 17% versus 11% (P < .2), whether initiated by a man or a woman. Persons who self-initiated had a lower HIV prevalence and fewer HIV-related risk behaviors. Analysis of variance assessed differences in the HIV risk profiles of female and male IDUs who were initiated by someone of the same sex, of the opposite sex, or who self-initiated. These results indicated that (1) young women and men had similar patterns of injection initiation; (2) most women were initiated by female friends, running counter to earlier literature claims that women were initiated to injection drug use by male sex partners; and (3) women initiated by men had a marginally greater mean score on the HIV risk profile.

Measures to prevent and reduce drug abuse among young people in Burma.

PubMed

Khant, U

1985-01-01

Opium and to a certain extent cannabis were the only drugs of abuse in Burma until the early 1970s when heroin addiction spread rapidly among young people, reaching epidemic proportions. Heroin addiction has caused serious social and health problems that prompted the authorities to adopt new legislation in 1974, the Narcotic and Dangerous Drugs Law, which provided for compulsory treatment and severe penalties for drug-related infractions, including the death sentence for certain categories of drug trafficking. The authorities in Burma consider that legislation, drug-law enforcement, prevention, treatment and rehabilitation, and community measures are important and interrelated strategies in combating drug abuse among young people. Various forms of drug-abuse preventive programmes are carried out for such groups as youths, parents, community leaders and professionals dealing with the problems of the young. Preventive school programmes include lectures and discussions; exhibitions; essay writing and other forms of competition for students; in-service training for teachers; healthy alternatives to drug use; a scheme for talented students; and participation in a national mass movement for literacy. Young people are also encouraged to take active part in various community programmes such as the "Red Cross" and voluntary fire brigades as well as in specially designed programmes that are carried out at the local level to prevent and reduce drug abuse. As the extended family still prevails in Burma, with parents and elders being respected by the young, this important resource is utilized in coping with drug abuse among young people.(ABSTRACT TRUNCATED AT 250 WORDS)

Review of HIV and HCV infection among drug users in China.

2010-05-01

Drug abuse has resulted in a huge public health and economic burden in China, especially the rapid spread of HIV/AIDS and hepatitis C virus (HCV) infection. Multiple HIV and HCV subtypes were detected among drug users in China, this study reviews the molecular distribution of HIV and HCV among injection drug users (IDUs) and explores new epidemiologic trends of HIV and HCV among drug users in China. The 2009 National Narcotic Control Commission report showed that the percentage of users of 'new-type drugs', including amphetamine-type stimulants (ATS: methamphetamine and MDMA/ecstasy) and ketamine, was about 27% of total drug users. The pooled data from published papers showed that CRF07BC was the predominant HIV-1 subtype, which accounted for 38.8%, and it was followed by AE, which accounted for 22.7% among HIV-positive IDUs. Following these, the CRF08BC, B' and C subtypes accounted for about 10.8%, 9.9% and 9.2%, respectively. Subtype 6a was the predominant HCV subtype, accounting for 36.7%, and subtypes 3b, 1a, 3a and 1b were the next most predominant subtypes. With the increase of 'new-type drugs' use and AE HIV-1 subtype infection among IDUs, the situation regarding HIV/AIDS and HCV infection has become complicated. More comprehensive prevention and intervention strategies should be instigated for the extensive high-risk populations in China.

Economic Impacts of the Generic Drug User Fee Act Fee Structure.

A Food and Drug Administration (FDA) Generic Drug User system, Generic Drug User Fee Amendment of 2012 (GDUFA), started October 1, 2012, and has been in place for over 3 years. There is controversy about the GDUFA fee structure but no analysis of GDUFA data that we could find. To look at the economic impact of the GDUFA fee structure. We compared the structure of GDUFA with that of other FDA Human Drug User fees. We then, using FDA-published information, analyzed where GDUFA facility and Drug Master File fees are coming from. We used the Orange Book to identify the sponsors of all approved Abbreviated New Drug Applications (ANDAs) and the S&P Capital IQ database to find the ultimate parent companies of sponsors of approved ANDAs. The key differences between the previous structure for Human Drug User fees and the GDUFA are as follows: GDUFA has no approved product fee and no first-time or small business fee exemptions and GDUFA charges facility fees from the time of filing and charges a foreign facility levy. Most GDUFA fees are paid by or on behalf of foreign entities. The top 10 companies hold nearly 50% of all approved ANDAs but pay about 14% of GDUFA facility fees. We conclude that the regressive nature of the GDUFA fee structure penalizes small, new, and foreign firms while benefiting the large established firms. A progressive fee structure in line with other human drug user fees is needed to ensure a healthy generic drug industry.

2012-12-01

Physical activity could benefit drug users' physiological and mental health. Previous research has suggested that physical activity levels change when drug users enter prison. Twenty-five class A drug users who were new to prison answered physical activity and drug use cross-sectional questionnaires, took a submaximal fitness test and wore a pedometer for 1 week. Participants' mean aerobic capacity was estimated as 49 mls O2/kg/min (±12 SD). Their mean self-reported walking distance outside of prison was 4.67 miles on an average day (±4.14 SD). Pedometer data suggest they walked a mean of 1.8 miles/day in prison. Many class A drug users entering prison had high levels of fitness and physical activity before admission, often gained from walking. Walking activity reduced when they entered prison, posing a challenge to maintaining healthy activity levels.

Impact of HIV prevention programs on drug users in Malaysia.

PubMed

Kamarulzaman, Adeeba

2009-11-01

Faced with a rising HIV epidemic among injecting drug users, harm reduction policies and programs were introduced in Malaysia in 2005. The positive impact seen since the introduction of these programs comprise the inclusion of the health aspects of illicit drug use in the country's drug policies; better access to antiretroviral therapy for injecting drug users who are HIV infected; reduction in HIV-risk behavior; and greater social benefits, including increased employment. Despite these achievements, tension between law enforcement and public health persists, as harm reduction exists alongside an overall drug policy that is based on abstinence and zero tolerance. Unless there is harmonization of this policy, sustainability and scale-up of harm reduction programs will remain a challenge.

2008-02-01

The aim of this study is to identify the social psychological determinants of the use of performance-enhancing drugs by gym users who practice bodybuilding, fitness, powerlifting or combat sports. In this questionnaire-based study, 144 respondents answered questions on their actual use and intention to use such drugs and also on their background characteristics and beliefs, such as their attitudes, social influences and self-efficacy. While all social psychological determinants correlated with intention to use these drugs, the most important predictors were personal norms, beliefs about performance outcomes and the perceived behavior of others. Non-users held more restrictive norms about using performance-enhancing drugs, were less optimistic about the performance-enhancing outcomes and believed that fewer significant others used performance-enhancing drugs than users and ex-users. The results of this study indicate that users attribute advantages to performance-enhancing drugs and are inclined to overlook the risks of using them. Preventive interventions should focus on influencing personal norms and social processes.

Illicit drug use is increasing among non-medical users of prescription drugs-Results from population-based surveys 2002-2014.

Non-medical use of prescription drugs (NMUPD) is known to be associated with illicit drug use, but less is known about how illicit drug use has changed in NMUPD. We examined (1) the changes in illicit drug use among Finnish non-medical users of prescription drugs during the 2000s and (2) whether the trends of illicit drug use differ by non-medical use of prescription drugs in the general population. Data were derived from population-based (aged 15-69) Drug Surveys conducted in Finland in 2002, 2006, 2010 and 2014. The response rates varied between 63% and 48%. NMUPD during the last year was measured (n=252). Past-year illicit drug use among non-medical users of prescription drugs and the reference population not reporting NMUPD (n=10,967) was compared. Logistic regression was used to estimate the p-values for trends. Illicit drug use has increased notably among Finnish non-medical users of prescription drugs (from 21% to 70%, p for trend<0.001). This was not explained by the respondents' gender, age, employment status or alcohol use. Among the reference population, illicit drug use also increased statistically significantly, but much more moderately (from 2.5% to 5.4%). The difference between the trends was confirmed by an interaction test (p=0.022). NMUPD seems to be increasingly merging with illicit drug use. This indicates an increasing prevalence of polydrug use among non-medical users of prescription drugs, which may bring about more severe harms and worse health outcomes for users and more challenges in regard to treatment.

We assessed prevalence of suicidal ideation and plans among illicit drug users and their association with contextual factors, by gender. Cross-sectional study. In a sample of 511 illicit drug users recruited during spring 2012 in drug treatment and prevention facilities in Catalonia (Spain), the prevalence of suicidal ideation/plans in the last 12 months was assessed. Poisson regression was used to examine associations between suicidal ideation/plans and various factors (socio-demographic, psychological, illegal drug market activities and marginal income generation activities, which included any reported sex work, stealing, peddling, begging or borrowing on credit from a dealer). The average age was 37.9 years (standard deviation: 8.62); 76.3% were men. Suicidal ideation/plans were reported by 30.8% of men and 38.8% of women, with no significant differences by age or gender. Recent aggression (male prevalence ratio [PR]=2.2; female PR=1.4), psychological treatment (male PR=1.2; female PR=1.3) and illegal/marginal income generation activities (male PR=1.5; female PR=1.1) were associated with suicidal ideation/plans. Men who trafficked were more likely to have suicidal ideation/plans (PR=1.3), while prison history was positive for women (PR=1.8) and negative for men (PR=0.7). Prevalence of suicidal ideation/plans was high among illicit drug users recruited from healthcare facilities. Besides psychological variables, participation in illegal market activities and crime ought to be considered in drug users' suicidal prevention. Suicide risk needs to be evaluated in drug treatment facilities and psychological status and context contemplated. Copyright © 2017 SESPAS. Publicado por Elsevier España, S.L.U. All rights reserved.

Early childhood experiences, parenting and the process of drug dependency among young people in Tehran, Iran.

2012-06-01

Substance abuse has become a major public health problem in Iran. The process of developing an addiction is complex and multifaceted. Early childhood experiences are thought to be one of the important determinants of addictive behaviour. The aim of this qualitative study is to explore the early childhood experiences, especially the experiences within the immediate family, of current substance-using young adults in Iran. The study is qualitative in nature. In-depth interviews were conducted with 15 young men and women who were either in treatment for their addiction or were active drug users at the time of the interviews. Moreover, four interviews have been conducted with family members of participants. The majority of the participants experienced traumatic events during childhood and came from dysfunctional families. There appears to be a significant disconnect between these individuals and their families. An obedience-instilling parenting style and parents' knowledge and attitude toward drug using and prevention were also identified as important determinants of substance use. The results of this research point out the need for early interventions for at-risk families as well as at-risk individuals. © 2011 Australasian Professional Society on Alcohol and other Drugs.

2015-01-01

Objectives. We demonstrated the effectiveness of an accelerated hepatitis B vaccination schedule in drug users. Methods. We compared the long-term effectiveness of accelerated (0–1–2 months) and standard (0–1–6 months) hepatitis B vaccination schedules in preventing hepatitis B virus (HBV) infections and anti-hepatitis B (anti-HBs) antibody loss during 2-year follow-up in 707 drug users (HIV and HBV negative at enrollment and completed 3 vaccine doses) from February 2004 to October 2009. Results. Drug users in the accelerated schedule group had significantly lower HBV infection rates, but had a similar rate of anti-HBs antibody loss compared with the standard schedule group over 2 years of follow-up. No chronic HBV infections were observed. Hepatitis C positivity at enrollment and age younger than 40 years were independent risk factors for HBV infection and antibody loss, respectively. Conclusions. An accelerated vaccination schedule was more preferable than a standard vaccination schedule in preventing HBV infections in drug users. To overcome the disadvantages of a standard vaccination schedule, an accelerated vaccination schedule should be considered in drug users with low adherence. Our study should be repeated in different cohorts to validate our findings and establish the role of an accelerated schedule in hepatitis B vaccination guidelines for drug users. PMID:25880946

Electrophysiological evidence of early attentional bias to drug-related pictures in chronic cannabis users.

PubMed

Asmaro, Deyar; Carolan, Patrick L; Liotti, Mario

2014-01-01

Behavioral and electrophysiological correlates of attentional bias to cannabis-related cues were investigated in a marijuana dependent group and a non-user group employing a drug Stroop task in which cannabis-related, negative and neutral images were presented. Behaviorally, cannabis users were less accurate during drug-containing blocks than non-users. Electrophysiologically, in chronic marijuana-users, an early positive ERP enhancement over left frontal scalp (EAP, 200-350ms) was present in response to drug-containing blocks relative to negative blocks. This effect was absent in the non-user group. Furthermore, drug-containing blocks gave rise to enhanced voltage of a posterior P300 (300-400ms), and a posterior sustained slow wave (LPP, 400-700ms) relative to negative blocks. However, such effects were similar between cannabis users and non-users. Brain source imaging in cannabis users revealed a generator for the EAP effect to drug stimuli in left ventromedial prefrontal cortex/medial orbitofrontal cortex, a region active in fMRI studies of drug cue-reactivity and a target of the core dopaminergic mesolimbic pathway involved in the processing of substances of abuse. This study identifies the timing and brain localization of an ERP correlate of early attentional capture to drug-related pictures in chronic marijuana users. The EAP to drug cues may identify a new electrophysiological marker with clinical implications for predicting abstinence versus relapse or to evaluate treatment interventions. © 2013.

Conditional rights, benefit reform, and drug users: reducing dependency?

PubMed

Harris, Neville

2010-01-01

United Kingdom government policy to increase social security claimants' entry to the labour market through conditions attached to unemployed, sickness and incapacity benefits now includes additional measures to activate particular groups such as lone parents and drug users. The latter are a prime target because of their high level of dependency on benefits and because social security rules are seen as having the potential to modify the behaviour of individuals with a lifestyle regarded as being at odds with the moral obligations of citizenship and incompatible with the government's realization of its wider economic and social goals. There are strict procedures for the identification of drug-user claimants, enabling additional conditions to be attached to their benefit rights. This article discusses the general trend in benefit reform towards increased conditionality and evaluates the reforms affecting drug users, considering human rights and other implications. It concludes by reflecting on the status of conditional rights to social security as social rights.

1994-01-01

OBJECTIVES. The purpose of this study was to assess the willingness of intravenous drug users to participate in a preventive human immunodeficiency virus (HIV) vaccine efficacy trial. METHODS. Of the 347 intravenous drug users in methadone treatment who were approached for participation, 257 completed a battery of self-administered questionnaires assessing risk behaviors, interest in vaccine trials, and other vaccine-related information. Data from 16 known seropositives and 1 inconsistent responder were dropped from analyses (n = 240). RESULTS. Fifty-two percent of the subjects expressed a willingness to be one of the first individuals to participate in a preventive HIV vaccine efficacy trial. Subjects who had recently shared needles or works and subjects who trusted the government to ensure vaccine safety were both twice as likely to report interest in participation. Twenty-two percent of subjects reported that they would increase needle sharing if vaccinated. Thirty percent did not know what a vaccine was. CONCLUSIONS. These findings suggest that some in-treatment intravenous drug users would volunteer for a preventive HIV vaccine efficacy trial. Education and counseling will be required to ensure that subjects fully understand the trial's purposes, methods, risks and benefits. PMID:8179045

2004-11-01

To examine associations between resilience in children of injection drug users and children's coping strategies, parenting stress, and children's social support. Injection drug-using parents (n=91) and their children aged 6 to 11 (n=117) were recruited in Baltimore (1997-1999). Resilience was defined as scoring in the lowest quartile of the Child Behavior Checklist total psychopathology score. Coping strategies used by resilient and nonresilient children, the extent and types of social support that they received, and the level of parenting stress reported by their parents were compared and contrasted. Rates of depressive, anxiety, and disruptive behavior disorders were 15.4%, 22.2%, and 21.4%, respectively, for the entire sample. Compared with the nonresilient, resilient children were less likely to use two avoidance coping strategies (internalizing [p=.002] and externalizing [p=.017]). The level of actual support received by resilient and nonresilient children did not differ significantly (p=.202). Perceived support was greater among resilient children (as reported by their parents; p <.001), and their parents reported lower parenting stress (p=.042). A significant proportion of children of injection drug users are in need of clinical care. Interventions to help children of substance-abusing parents modify their coping style merit exploration.

We interviewed 50 current cocaine users with the aim of providing insights into cocaine use in Sydney. The study sample was obtained by one researcher using a chain referral technique. Appointments were made for interview and the interview aimed to determine the quantity, frequency, pattern and circumstances of drug use in the respondents. The study sample included people with a wide range of incomes and occupations; all but one person were employed. Extensive current drug use was reported; 78% smoked tobacco, 98% drank alcohol with 36% having more than two drinks per day, 96% used marijuana with 40% smoking marijuana at least 5 times per week, 65% used amphetamines, 36% used hallucinogens and 10% used heroin. Ten per cent were unable to name one health risk of cocaine. When asked about the image of a cocaine user, 42% thought of a rock star, film industry worker or someone involved in the arts and entertainment world. The information obtained from a study such as this provides important data for targeting of people in anti-drug campaigns.

Age of first use and ongoing patterns of legal and illegal drug use in a sample of young Londoners.

PubMed

McCambridge, Jim; Strang, John

2005-01-01

The significance of ages of first use of cigarettes, alcohol, cannabis, and stimulant drugs were investigated in a sample of young drug users entering an intervention study in London. Age of first cigarette smoking emerges as a robust predictor of age of first cannabis use, and age of first cannabis use in turn is predictive of age of first stimulant use, among those using both drugs. In this sample, ages of first use of cigarettes, alcohol, and cannabis are not predictive of whether stimulant drugs are used. In a series of regression models that take account of the influence of other factors, age of first use is found to have no relationship to levels of ongoing consumption of cigarettes, alcohol, and cannabis.

Gunn, Alana; Guarino, Honoria

2017-01-01

Background Young people from the former Soviet Union (FSU) in the U.S. are engaging in opioid and injection drug use (IDU) in substantial numbers, paralleling nationwide trends. Yet opioid-using FSU immigrants face distinctive acculturation challenges, including perceived stigmatisation as drug users within their immigrant communities, which may exacerbate the negative health and psychosocial consequences of such use. Methods This qualitative study draws on semi-structured interviews with 26 FSU immigrant young adults (ages 18–29) living in New York City who reported opioid use in the past month and/or were currently in treatment for opioid use disorder. Interviews probed youths’ drug use histories, immigration/acculturation experiences, family and peer relationships, and service utilisation. Interviews or focus groups were also conducted with 12 FSU mothers of opioid-using youth and 20 service providers familiar with the FSU population. In a content-based thematic analysis, verbatim transcripts were coded for salient themes. Results All three participant groups emphasized that stigma towards drug users within the FSU community is pervasive and acute, in contrast to the cultural acceptance of heavy drinking, and is rooted in punitive Soviet-era drug policies, fostering widespread ignorance about drugs and addiction. Young adults and service providers reported instances in which anticipation of community stigmatisation deterred youth from accessing drug treatment and harm reduction services. Similarly, stigma contributed to parents’ failure to recognize early signs of their children’s opioid problems and their reluctance to seek drug treatment for their children until opioid use had become severe. Young adults described how drug-use stigma is frequently internalized, leading to shame and loss of self-esteem. Conclusion Findings indicate an urgent need for community-wide education about drugs within FSU immigrant communities, and suggest specific service

Drug driving and the management of risk: the perspectives and practices of a sample of problem drug users.

PubMed

McIntosh, James; O'Brien, Tommy; McKeganey, Neil

2008-06-01

This paper reports on a qualitative study of the attitudes and risk management strategies of a sample of problem drug users in relation to driving while under the influence of drugs. Interviews were conducted with 26 individuals (21 men and 5 women) all of whom had been addicted to heroin and had admitted to driving while under the influence of illegal drugs. The drug users reported four main strategies for managing the risks associated with drug driving: attempting to limit their drug intake to their tolerance level; delaying driving after taking a drug until they felt safe; stopping driving if they felt unsafe while behind the wheel; and avoiding driving altogether under the influence of certain drugs. However, the interviewees' accounts of their drug driving behaviour suggest that these strategies are not only far from reliable, they may also act to encourage drug driving by creating a false sense of security. The reassurance they provide may also undermine any educational messages targeting drug driving. There was little in the problem users' accounts to suggest that media campaigns or a more effective method of detection would have much influence upon their behaviour. The paper concludes that the most realistic approach to the problem may be to incorporate drug driving interventions within drug treatment programmes.

A harm reduction programme for injecting drug users in Nepal.

PubMed

Singh, M

1997-01-01

The Lifesaving and Lifegiving Society (LALS), a street-based nongovernmental organization established in Nepal in 1991, utilizes a harm-reduction strategy to minimize the spread of HIV among injecting drug users. Community health outreach workers, many of whom are former drug addicts, work in the streets of Kathmandu, educating, counseling, and distributing bleach, sterile water, swabs, and clean needles. They demonstrate how to clean syringes and distribute condoms. LALS also provides primary health care services such as treatment for abscesses. Clients are informed about the limited drug treatment services in Nepal and are offered the option of home detoxification under LALS supervision. LALS promotes the message that drug users should be treated as victims of a disease rather than as criminals. Family involvement, fostered through home visits, is considered important to sustaining behavioral changes and family members are informed about ways of encouraging drug users to give up drug use or at least practice safe injecting techniques. Education of and networking with Narcotics Division and other police officers has been essential to LALS' success. LALS is working with the Nepali Red Cross on integrating HIV prevention into family planning programs. A current priority is to reduce dependence on funding from donor agencies and mobilize support from private businesses.

The presentation of fever in an intravenous drug user prompts diagnostic testing targeted at identifying infectious etiologies. However, an alternate diagnosis exists in "cotton fever." While few reports describe this phenomenon in the peer-reviewed literature, the diagnosis is well recognized among the intravenous drug user community. Although its etiology is not well understood, cotton fever seems to be a self-limited, febrile response to the intravenous administration of a drug filtered through cotton. Educating clinicians regarding cotton fever may limit unnecessary hospital admissions and improve our ability to care for this population. © Copyright 2016 by the American Board of Family Medicine.

HIV infection among intravenous drug users: epidemiology and risk reduction.

PubMed

Des Jarlais, D C; Friedman, S R

1987-07-01

Research on the epidemiology of HIV infection among IV drug users is still at a relatively early stage. Multilocation studies that would permit better geographic comparisons are greatly needed. Multi-method studies within single geographic areas are also needed to assess possible biases with respect to sample recruitment and data collection procedures. The continuation of the epidemic provides a changing historical context that complicates any comparisons. Despite these problems, there are some consistencies that can be seen across studies. Studies of HIV seroprevalence among IV drug users show wide variation among cities in the United States and Europe. The time that the virus was introduced into the IV drug using group within the city is one factor in explaining these differences; other cross-city factors have yet to be identified. Once HIV has been introduced into the IV drug use group within a particular geographic area, there is the possibility of rapid spread up to seroprevalence levels of 50% or greater. Thus, a currently low seroprevalence rate should not be seen as a stable situation. Frequency of injection and sharing of equipment with multiple other drug users (particularly at shooting galleries) have been frequently associated with HIV exposure. Being female, ethnicity (in the USA) and engaging in prostitution also may be associated with increased risk for HIV exposure, suggesting that prevention programs should include special consideration of sex and ethnic differences. Studies of AIDS risk reduction show that substantial proportions of IV drug users are changing their behavior to avoid exposure to HIV. This risk reduction is probably more advanced in New York, with its high seroprevalence and incidence of cases, but is also occurring in cities with lower seroprevalence and limited numbers of cases. The primary forms of risk reduction are increasing the use of sterile equipment, reducing the number of needle sharing partners, and reducing the

We examined the association between adolescent sexual debut and age at new-type drug initiation among a sample of young adult new-type drug users. A total of 276 participants were recruited using respondent-driven sampling (RDS) in Shanghai, China. The analyses were restricted to a total of 201 participants aged between 18 and 30 years. The average age at sexual debut and age at first new-type drug use were 18.8 and 20.9 years, respectively. About 94% of participants reported having sexual experience (n = 188); of those, 137 (72.9%) had sexual debut before they first used new-type drugs, while 32 (17.0%) initiated both events at the same age. After adjustment for age, income, education, and sexual orientation, adolescent sexual debut was independently associated with younger age at new-type drug initiation. Adolescent sexual debut is associated with early onset of new-type drug use. Our findings underscore the importance of implementing sex-education programs for adolescents in schools in China.

Patients and consumers have desired high quality drug information in their pharmacotherapy, and are entitled to receive it. It is desirable that the information should be aimed at shared decision-making between patients and healthcare professionals about medications. The quality of drug information available to patients should also be assured. With an aim to improve the quality of "Drug Guide for Patients", we investigated Patient Information Leaflets (PILs) which are approved by the Medicines and Healthcare Products Regulatory Agency (MHRA) in the United Kingdom (UK) with regard to the criteria of development and user testing for assuring the quality of the PILs. In the European Union (EU), these are called Package Leaflets (PLs). PILs have been a legal requirement in the UK since 1999 for all medications. The user testing of PILs has been implemented as evidence since 2005 so that people can rely on the information provided in the leaflet. Execution of PILs which follow the guidance of the user testing, according to the guidance of this user testing, would reflect the views of patients. Here, we introduce the development process and implementation of user testing of PILs. In terms of readability, accessibility and understandability of drug information for patients, we need to discuss involving the public in decisions on how its quality should be assured and how it can be made easily be comprehensible for patients, in order to make effective use of "Drug Guide for Patients" in the future in Japan.

The most high-risk population for HCV transmission worldwide today are intravenous drug users. HCV genotypes in the general population in Cyprus demonstrate a polyphyletic infection and include subtypes associated with intravenous drug users. The prevalence of HCV, HBV, and HIV infection, HCV genotypes and risk factors among intravenous drug users in Cyprus were investigated here for the first time. Blood samples and interviews were obtained from 40 consenting users in treatment centers, and were tested for HCV, HBV, and HIV antibodies. On the HCV-positive samples, viral RNA extraction, RT-PCR and sequencing were performed. Phylogenetic analysis determined subtype and any relationships with database sequences and statistical analysis determined any correlation of risk factors with HCV infection. The prevalence of HCV infection was 50%, but no HBV or HIV infections were found. Of the PCR-positive samples, eight (57%) were genotype 3a, and six (43%) were 1b. No other subtypes, recombinant strains or mixed infections were observed. The phylogenetic analysis of the injecting drug users' strains against database sequences observed no clustering, which does not allow determination of transmission route, possibly due to a limitation of sequences in the database. However, three clusters were discovered among the drug users' sequences, revealing small groups who possibly share injecting equipment. Statistical analysis showed the risk factor associated with HCV infection is drug use duration. Overall, the polyphyletic nature of HCV infection in Cyprus is confirmed, but the transmission route remains unknown. These findings highlight the need for harm-reduction strategies to reduce HCV transmission. (c) 2009 Wiley-Liss, Inc.

To understand the change of behavioral characteristics among drug users (DUS) in Tianjin and the prevalence rates of major sexually transmitted disease infections. A series of cross-sectional surveys were used. Between April and June, 2011 to 2015, a cross-sectional survey with face to face interview, was undertaken. Interview was conducted among DUS who entered the drug rehabilitation center and blood samples were drawn to test for HIV/syphilis/HCV infections. Multivariate logistic regression analysis was used to analyze the relationship between the infection of major sexually transmitted diseases and drug abuse or sexual behavior. 2 000 DUS were included during the 5-year study, with the average age of the DUS as 34.5 ± 8.7. Female accounted for 17.9% and club drug (new drugs) users accounted 45.4% of the participants, with its proportion increasing over the years. Comparing to traditional drug users, club drug users showed more sexual activities with partners, but lower proportion of condom use. Prevalence rates of HIV/Syphilis and HCV were 1.3%, 11.0%, 52.0%, respectively. The prevalence of syphilis among club drug users was significantly higher than those on traditional-drug use (χ(2)=67.778,P<0.001). Data from Binary logistic regression analysis showed that club drug use (adjusted OR=1.607, 95% CI:1.191-2.170) and females (adjusted OR=5.287, 95%CI: 3.824-7.311) were associated with syphilis infection among DUS. Drug abuse behavior changed among the drug abuse in Tianjin. Proportion of club drug use continued to increase so as the risk of infected sexually transmitted diseases.

Though research indicates a complex link between substance use and sexual risk behavior, there is limited research on the association between sexual risk behavior and prescription drug misuse. In light of alarming increases in prescription drug misuse and the role of demographic characteristics in sexual risk behavior and outcomes, the current study examined demographic differences (gender, sexual identity, age, relationship status, parental class background, and race/ethnicity) in sexual risk behavior, sexual behavior under the influence of prescription drugs, and sexual risk behavior under the influence of prescription drugs in a sample of 402 young adults (ages 18 to 29) who misused prescription drugs. Nearly half of the sexually active young adult prescription drug misusers in this sample reported recent sex under the influence of prescription drugs; more than three-quarters reported recent sex without a condom; and more than one-third reported recent sex without a condom after using prescription drugs. Zero-inflated Poisson regression models indicated that White race, younger age, higher parental class, and being a heterosexual man were all associated with sexual risk behavior, sex under the influence of prescription drugs, and sexual risk under the influence of prescription drugs. Findings have implications for the targeting of prevention and intervention efforts.

2014-01-01

The purpose of this study was to investigate the longitudinal effect of marijuana and heavy alcohol use on the productivity status of nonmetropolitan African American young adults. This analysis was based on secondary data from the Family and Community Health Study. For alcohol, the study evaluated the effects on productivity status for individuals with heavy alcohol use trajectories from adolescence into young adulthood while marijuana effects were evaluated during the period when adolescents are more likely to have initiated usage (14-16 years of age). Productivity status was measured when study participants were between 18 and 21 years, for both alcohol and marijuana. Multivariate logistic regression models were used to test the association between subjects' drug use and productivity. Bivariate analysis of the effects of marijuana use indicate that marijuana users by age 16 are 35% less likely to be productive at age 21 than those who have not initiated marijuana use (p < .005). After controlling for individual, community, and family factors, the multivariate logistic models for alcohol and marijuana use suggest that early adolescence drug use (marijuana and heavy alcohol use) do not have an impact on productivity status during early adulthood. Analyzing and understanding the different drug use trajectories in relation to a productivity outcome is important for policies and research geared to preventing drug use and in identifying its relation with micro- and macro-level labor market outcomes. © The Author(s) 2015 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.

Intracerebral haemorrhage and drug abuse in young adults.

2000-10-01

The epidemic of abuse of the so-called 'designer drugs' amphetamine, cocaine and ecstasy--is fast replacing traditional aetiological factors as the largest cause of intracerebral haemorrhage among young adults. Traditional teaching is that these represent hypertensive haemorrhages. Recent reports, however, have indicated that these patients may harbour underlying vascular malformations. We review 13 patients with a positive history of drug abuse preceding the onset of intracerebral haemorrhage. These patients presented to the National Hospital for Neurology and Neurosurgery in central London over a 7-month period. Of the 13 patients (eight male, five female), average age 31 years (19-43) years), 10 were well enough to undergo cerebral angiography. Intracranial aneurysms were demonstrated in six patients and arteriovenous malformations in three patients. In only one of the patients was the angiogram normal. A further patient was subsequently shown to have a middle cerebral artery aneurysm at autopsy. The epidemiology, pharmacology and systemic effects of these drugs are considered. The mechanisms by which these compounds cause intracerebral complications and their influence on prognosis are discussed. The incidence of intracerebral haemorrhage (ICH), ischaemic cerebral infarctions and subarachnoid haemorrhage (SAH) following drug abuse is increasing. Contrary to historical opinion, drug-related ICH is frequently related to an underlying vascular malformation. Arteriography should be part of the evaluation of most young patients with nontraumatic ICH. A thorough history focusing on the use of illicit substances and toxicological screening of urine and serum should be part of the evaluation of any young patient with a stroke.

Fertility drugs stimulate hyperovulation, which may have implications for breast cancer. We examined the association between use of fertility drugs (clomiphene citrate [CC] and follicle-stimulating hormone [FSH]) and subsequent risk of young-onset (<50 years at diagnosis) breast cancer. We conducted the Two Sister Study, a sister-matched case-control study, by enrolling 1422 women between September 2008 and December 2010, who were younger than age 50 years at diagnosis with breast cancer and were enrolled within 4 years of diagnosis, and 1669 breast cancer-free control sisters from the Sister Study. Participants reported their use of fertility drugs (CC and FSH) and ever-users reported whether a pregnancy had resulted that lasted 10 or more (10+) weeks. Conditional logistic regression was used to estimate confounder-adjusted odds ratios (ORs) and 95% confidence intervals (CIs) for fertility drug use with or without conception of a 10+ week pregnancy. A total of 288 participants reported having used ovulation-stimulating drugs (193 CC only, 29 FSH only, and 66 both). Overall, women who had used fertility drugs showed a non-statistically significantly decreased risk of breast cancer, compared with nonusers (OR = 0.82, 95% CI = 0.63 to 1.08). Women who had used fertility drugs but had not conceived a 10+ week pregnancy under treatment showed a statistically significantly decreased risk of breast cancer compared with nonusers (OR = 0.62, 95% CI = 0.43 to 0.89). Women who had used fertility drugs and conceived a 10+ week pregnancy under treatment showed a statistically significantly increased risk of breast cancer compared with unsuccessfully treated women (OR = 1.82, 95% CI = 1.10 to 3.00), although their risk was not increased compared with women who had not used fertility drugs (OR = 1.13, 95% CI = 0.78 to 1.64). In the absence of a 10+ week pregnancy under treatment, exposure to ovulation-stimulating fertility drugs was associated with reduced risk of young

OBJECTIVES: This study deter- mined human immunodeficiency virus (HIV) seroprevalence and factors associated with HIV infection among street-recruited injection drug users and crack cocaine smokers. METHODS: An analysis was performed on HIV serologies and risk behaviors of 6402 injection drug users and 3383 crack smokers in 16 US municipalities in 1992 and 1993. RESULTS: HIV seroprevalence was 12.7% among injection drug users and 7.5% among crack smokers. Most high-seroprevalence municipalities (>25%) were located along the eastern seaboard of the United States. In high-seroprevalence municipalities, but not in others, HIV seroprevalence was higher for injection drug users than for crack smokers. Among injection drug users, cocaine injection, use of speedballs (cocaine or amphetamines with heroin), and sexual risk behaviors were independently associated with HIV infection. Among crack smokers, sexual risk behaviors were associated with HIV infection. CONCLUSIONS: Injection drug users and crack smokers are at high risk for HIV infection. PMID:9584014

A pilot study of loss aversion for drug and non-drug commodities in cocaine users.

Numerous studies in behavioral economics have demonstrated that individuals are more sensitive to the prospect of a loss than a gain (i.e., loss aversion). Although loss aversion has been well described in "healthy" populations, little research exists in individuals with substance use disorders. This gap is notable considering the prominent role that choice and decision-making play in drug use. The purpose of this pilot study was to evaluate loss aversion in active cocaine users. Current cocaine users (N=38; 42% female) participated in this within-subjects laboratory pilot study. Subjects completed a battery of tasks designed to assess loss aversion for drug and non-drug commodities under varying risk conditions. Standardized loss aversion coefficients (λ) were compared to theoretically and empirically relevant normative values (i.e., λ=2). Compared to normative loss aversion coefficient values, a precise and consistent decrease in loss aversion was observed in cocaine users (sample λ≈1). These values were observed across drug and non-drug commodities as well as under certain and risky conditions. These data represent the first systematic study of loss aversion in cocaine-using populations and provide evidence for equal sensitivity to losses and gains or loss equivalence. Futures studies should evaluate the specificity of these effects to a history of cocaine use as well as the impact of manipulations of loss aversion on drug use to determine how this phenomenon may contribute to intervention development efforts.

Marijuana is the most commonly used illicit drug in the United States, but little is known about its effects on the human brain, particularly on reward/aversion regions implicated in addiction, such as the nucleus accumbens and amygdala. Animal studies show structural changes in brain regions such as the nucleus accumbens after exposure to Δ9-tetrahydrocannabinol, but less is known about cannabis use and brain morphometry in these regions in humans. We collected high-resolution MRI scans on young adult recreational marijuana users and nonusing controls and conducted three independent analyses of morphometry in these structures: (1) gray matter density using voxel-based morphometry, (2) volume (total brain and regional volumes), and (3) shape (surface morphometry). Gray matter density analyses revealed greater gray matter density in marijuana users than in control participants in the left nucleus accumbens extending to subcallosal cortex, hypothalamus, sublenticular extended amygdala, and left amygdala, even after controlling for age, sex, alcohol use, and cigarette smoking. Trend-level effects were observed for a volume increase in the left nucleus accumbens only. Significant shape differences were detected in the left nucleus accumbens and right amygdala. The left nucleus accumbens showed salient exposure-dependent alterations across all three measures and an altered multimodal relationship across measures in the marijuana group. These data suggest that marijuana exposure, even in young recreational users, is associated with exposure-dependent alterations of the neural matrix of core reward structures and is consistent with animal studies of changes in dendritic arborization.

Myonecrosis remains one of the severest manifestations of skin and soft tissue infections. Clostridia (C. perfringens, C. novyi, C. septicum, C. sordellii, C. histolyticum) are dominant and Staphylococcus aureus, Streptococcus pyogenes, Bacillus cereus, and Bacteriodes fragilis are much less in the etiology of myonecrosis. Cases of gas gangrene have recently become more frequent among injection drug users all over the world. Russia has become the largest opiate market in Europe and consumption of these narcotic drugs is annually growing. In the Russian Federation, a larger number of injection drug users uniquely results in a rise of cases of Clostridium- and mixed flora-induced myonecrosis. Gas gangrene in HIV-positive drug abusers seems to rapidly progress to multiple organ failure and to show high death rates, rather than to develop a localized form. The analyzed case of mixed flora-induced gas gangrene is of interest to physicians of any specialties who can encounter this wound infection in HIV-positive patients.

Prevalent new-user cohort designs for comparative drug effect studies by time-conditional propensity scores.

Studies of the real-world comparative effectiveness of drugs conducted using computerized healthcare databases typically involve an incident new-user cohort design for head-to-head comparisons between two medications, using exclusively treatment-naïve patients. However, the desired contrast often involves one new drug compared with an older drug, of which many users of the new drug may have switched from, seriously restricting the scope of incident new-user studies. We introduce prevalent new-user cohort designs for head-to-head comparative drug effect studies, where incident new users are scarce. We define time-based and prescription-based exposure sets to compute time-conditional propensity scores of initiating the newer drug and to identify matched subjects receiving the comparator drug. We illustrate this approach using data from the UK's Clinical Practice Research Datalink to evaluate whether the newer glucagon-like peptide-1 receptor agonists (GLP-1 analogs) used to treat type 2 diabetes increase the risk of heart failure, in comparison with the older similarly indicated sulfonylureas. Of the 170 031 users of antidiabetic agents from 2000 onwards, 79 682 used sulfonylureas (first use 2000), while 6196 used GLP-1 analogs (first use 2007), 75% of which had previously used a sulfonylurea. After matching each GLP-1 analog user to a sulfonylurea user on the time-conditional propensity scores from prescription-based exposure sets, the hazard ratio of heart failure with GLP-1 use was 0.73 (95%CI: 0.57-0.93). The proposed prevalent new-user cohort design for comparative drug effects studies allows the use of all or most patients exposed to the newer drug, thus permitting a more comprehensive assessment of a new drug's safety.

During the last decade, the veterinary anesthetics have gained popularity as recreational drugs. The aim of this study was to document the use of "anestecia de caballo" (xylazine) and its consequences among drug users in Puerto Rico. The study combined a cross-sectional survey with 89 drug users and two focus groups conducted in Mayagüez with frontline drug treatment providers. Drug users were recruited from communities of the San Juan metropolitan area using a variety of ethnographic and outreach strategies. A short questionnaire developed for the study collected information on sociodemographics, xylazine use, and its consequences. The two focus groups were conducted to discuss the details related to xylazine use, its consequences, and utilization awareness. The sample comprised 63 males (70.8%) and 26 females with a mean age of 37.2 years. The mean number of years of drug use was 14.3, with a mean frequency of drug use of 5.9 times daily. More than 65% reported speedball as the principal drug of use. The prevalence of xylazine use was 80.7%. More than 42% of the sample used xylazine in a mixture with speedball. The main route of administration of xylazine was injection but 14% reported the use of xylazine by inhalation. More than 35% of the sample reported skin lesions and 21.1% reported at least one overdose episode. Multiple logistic regression analysis revealed that males (OR = 3.47, CI = 1.10-12.00) and those who reported speedball as their main drug of use (OR = 9.34, CI = 2.51-34.70) were significantly more likely to be xylazine users. Focus groups revealed that drug users claimed to recognize the presence of xylaxine in a mixture of speedball based on its effects, taste, the color of the drug (dark brown), and its odor. In conclusion, the use of xylazine among drug users in Puerto Rico seems to be an emerging trend with potentially serious health consequences.

2015-01-01

Previous studies have reported that peer groups are one of the most important predictors of adolescent and young adult marijuana use, and yet the neural correlates of social processing in marijuana users have not yet been studied. In the current study, marijuana-using young adults (n = 20) and non-using controls (n = 22) participated in a neuroimaging social exclusion task called Cyberball, a computerized ball-tossing game in which the participant is excluded from the game after a pre-determined number of ball tosses. Controls, but not marijuana users, demonstrated significant activation in the insula, a region associated with negative emotion, when being excluded from the game. Both groups demonstrated activation of the ventral anterior cingulate cortex (vACC), a region associated with affective monitoring, during peer exclusion. Only the marijuana group showed a correlation between vACC activation and scores on a self-report measure of peer conformity. This study indicates that marijuana users show atypical neural processing of social exclusion, which may be either caused by, or the result of, regular marijuana use. PMID:26977454

Characteristics and behaviors of early-onset injection drug users are under studied topics in Iran. This study aimed to identify and compare the demographic characteristics as well as the drug using behaviors of early-onset and late-onset injection drug users in Kermanshah, West Iran. In this cross-sectional study using snowball and convenience sampling, we recruited 450 people during the Fall of 2014 from two drop in centers in Kermanshah, Iran. We collected data through face-to-face interviews. Early-onset injection is defined as whether the person reported their first injection at 22 years of age or younger. Subsequently, late-onset injection is defined as 23 years of age or older. We compared the characteristics of the two groups through both univariate and multiple logistic analyses. Overall, 54% (CI 95%: 44.3%, 62.2%) were early injectors. After controlling for low socioeconomic status, initiation of drug use at a young age, multiple drug use and methamphetamine use were all significantly associated with a higher likelihood of early-onset injection. Additionally, early-onset injection was associated with recent syringe borrowing (OR = 2.6, p = 0.001), recent syringe lending (OR = 1.4, p = 0.01), recent cooker sharing (OR = 3.2, p = 0.01) and injecting two or more times a day (OR = 2.2, p = 0.04). Early-onset injectors were more likely to report a lower socioeconomic status, initiation of first drug use at a younger age, using methamphetamine alongside polydrug use, and engaging in higher risk taking behaviors like borrowing needles. With these associations, the study emphasizes the need for drug-prevention programs to focus on the transition to injection drug use at younger ages.

Social marketing involves applying marketing principles to promote social goods. In the context of health behavior, it has been used successfully to reduce alcohol-related car crashes, smoking among youths, and malaria transmission, among other goals. Features of social marketing, such as audience segmentation and repeated exposure to prevention messages, distinguish it from traditional health promotion programs. A recent review found 8 of 10 rigorously evaluated social marketing interventions responsible for changes in HIV-related behavior or behavioral intentions. We studied 479 injection drug users to evaluate a community-based social marketing campaign to reduce injection risk behavior among drug users in Sacramento, California. Injecting drugs is associated with HIV infection in more than 130 countries worldwide.

In the context of health behavior, it has been used successfully to reduce alcohol-related car crashes, smoking among youths, and malaria transmission, among other goals. Features of social marketing, such as audience segmentation and repeated exposure to prevention messages, distinguish it from traditional health promotion programs. A recent review found 8 of 10 rigorously evaluated social marketing interventions responsible for changes in HIV-related behavior or behavioral intentions. We studied 479 injection drug users to evaluate a community-based social marketing campaign to reduce injection risk behavior among drug users in Sacramento, California. Injecting drugs is associated with HIV infection in more than 130 countries worldwide. PMID:20724686

Careers in Drug and Alcohol Research: AN Innovative Program for Young Appalachian Women

NASA Astrophysics Data System (ADS)

Noland, Melody Powers; Leukefeld, Carl; Reid, Caroline

Supported by a grant from the National Institute on Drug Abuse, the University of Kentucky's Center on Drug and Alcohol Research developed the Young Women in Science Program to encourage young women from Appalachia to pursue scientific careers гп drug and alcohol research. This 3-year program, which involved 26 young women entering the ninth grade in 13 counties in southeastern Kentucky, included a summer residential program, community educational sessions, and matching students with mentors. When participants' scores prior to and after the 3-week residential program were compared, it was found that participants increased their science knowledge and improved their scores on confidence in science. Other significant changes occurred as well. These preliminary data indicated that some positive changes resulted from the program, even though contact time with the young women has been modest to date. The program shows considerable promise for providing the encouragement and skills needed for these young women to pursue careers in drug and alcohol research.

This pilot study tested the efficacy of a brief intervention using motivational interviewing (MI) plus mindfulness meditation (MM) to reduce marijuana use among young adult female. Thirty-four female marijuana users between the ages of 18–29 were randomized to either the intervention group (n = 22), consisting of 2 sessions of MI-MM or an assessment-only control group (n = 12). Participants’ marijuana use was assessed at baseline, 1, 2, and 3 months post-treatment. Fixed-effects regression modeling was used to analyze treatment effects. Participants randomized to the intervention group were found to use marijuana on 6.15 (z = −2.42, p=.015), 7.81 (z = −2.78, p=.005), and 6.83 (z = −2.23, p=.026) fewer days at months 1, 2, and 3, respectively, than controls. Findings from this pilot study provide preliminary evidence for the feasibility and effectiveness of a brief MI-MM for young adult female marijuana users. PMID:21940136

More than 8 of 10 intravenous drug users infected with the human immunodeficiency virus (HIV) are black or Hispanic. Recognizing that sociocultural factors affect HIV transmission, public health officials have called for interventions designed for ethnic-racial minority groups. Considered in this paper are the nature and extent of AIDS among ethnic-racial minorities and the cultural aspects of drug use and sexual behavior related to HIV transmission. That drug users and their associates are practicing safer needle use is evident; that they are changing their sexual behavior is less so. Calling for rapid advances in knowledge and expanded efforts in intervention, Federal agencies have instituted numerous programs to support innovative research and demonstration projects in ethnic-racial minority communities. Needed are studies that (a) describe the phenomena of drug use and sexual behavior among ethnic-racial minority populations, (b) establish the efficacy of culturally specific AIDS prevention strategies in drug treatment and community settings, and (c) demonstrate new ways of recruiting, treating, and reducing relapse among drug users.

Most young people killed in road crashes are known as vulnerable road users. A combination of physical and developmental immaturity as well as inexperience increases the risk of road traffic accidents with a high injury severity rate. Understanding injury mechanism and pattern in a group of young road users may reduce morbidity and mortality. This study analyzes injury patterns and outcomes of young road users compared to adult road users. The comparison takes into account different transportation related injury mechanisms. A retrospective analysis using data collected between 2002 and 2012 from the TraumaRegister DGU® was performed. Only patients with a transportation related injury mechanism (motor vehicle collision (MVC), motorbike, cyclist, and pedestrian) and an ISS ≥ 9 were included in our analysis. Four different groups of young road users were compared to adult trauma data depending on the transportation related injury mechanism. Twenty four thousand three hundred seventy three, datasets were retrieved to compare all subgroups. The mean ISS was 23.3 ± 13.1. The overall mortality rate was 8.61%. In the MVC, the motorbike and the cyclist group, we found young road users having more complex injury patterns with a higher AIS pelvis, AIS head, AIS abdomen and AIS of the extremities and also a lower GCS. Whereas in these three sub-groups the adult trauma group only had a higher AIS thorax. Only in the group of the adult pedestrians we found a higher AIS pelvis, AIS abdomen, AIS thorax, a higher AIS of the extremities and a lower GCS. This study reports on the most common injuries and injury patterns in young trauma patients in comparison to an adult trauma sample. Our analysis show that in contrast to more experienced road users our young collective refers to be a vulnerable trauma group with an increased risk of a high injury severity and high mortality rate. We indicate a striking difference in terms of the region of injury and the mechanism of

From Abstinence to Relapse: A Preliminary Qualitative Study of Drug Users in a Compulsory Drug Rehabilitation Center in Changsha, China

Background Relapse among abstinent drug users is normal. Several factors are related to relapse, but it remains unclear what individuals’ actual life circumstances are during periods of abstinence, and how these circumstances facilitate or prevent relapse. Objective To illuminate drug users’ experiences during abstinence periods and explore the real-life catalysts and inhibitors contributing to drug use relapse. Method Qualitative in-depth interviews were conducted with 20 drug users recruited from a compulsory isolated drug rehabilitation center in Changsha. The interviews were guided by open-ended questions on individuals’ experiences in drug use initiation, getting addicted, treatment history, social environment, abstinence, and relapse. Participants were also encouraged to share their own stories. Interviews were digitally recorded and fully transcribed. The data of 18 participants who reported abstinence experiences before admission were included in the analyses. The data were analyzed using a thematic analysis with inductive hand coding to derive themes. Results Most drug users were able to successfully abstain from drugs. During abstinence, their lives were congested with challenges, such as adverse socioeconomic conditions, poor family/social support, interpersonal conflicts, and stigma and discrimination, all of which kept them excluded from mainstream society. Furthermore, the police’s system of ID card registration, which identifies individuals as drug users, worsened already grave situations. Relapse triggers reported by the participants focused mainly on negative feelings, interpersonal conflicts, and stressful events. Craving was experienced but not perceived as a relapse trigger by most participants. Conclusions This study of in-depth interview with drug users found evidence of situations and environments they live during abstinence appear rather disadvantaged, making it extremely difficult for them to remain abstinent.

2015-01-01

Genetic testing will soon enter care for human immunodeficiency virus (HIV) and hepatitis C virus (HCV), and for addiction. There is a paucity of data on how to disseminate genetic testing into healthcare for marginalized populations. We explored drug users' perceptions of genetic testing. Six focus groups were conducted with 34 drug users recruited from syringe exchange programmes and an HIV clinic between May and June 2012. Individual interviews were conducted with participants reporting previous genetic testing. All participants expressed acceptance of genetic testing to improve care, but most had concerns regarding confidentiality and implications for law enforcement. Most expressed more comfort with genetic testing based on individual considerations rather than testing based on race/ethnicity. Participants expressed comfort with genetic testing in medical care rather than drug treatment settings and when specifically asked permission, with peer support, and given a clear rationale. Although participants understood the potential value of genetic testing, concerns regarding breaches in confidentiality and discrimination may reduce testing willingness. Safeguards against these risks, peer support, and testing in medical settings based on individual factors and with clear rationales provided may be critical in efforts to promote acceptance of genetic testing among drug users.

Nonnatural deaths among users of illicit drugs: pathological findings and illicit drug abuse stigmata.

PubMed

Delaveris, Gerd Jorunn Møller; Hoff-Olsen, Per; Rogde, Sidsel

2015-03-01

The aim of the study was to provide information on illicit drug abuse stigmata and general pathological findings among an adult narcotic drug-using population aged 20 to 59 years whose death was nonnatural. A total of 1603 medicolegal autopsy reports from 2000 to 2009 concerning cases positive for morphine, heroin, amphetamines, ecstasy, cannabis, LSD (lysergic acid diethylamide), PCP (phencyclidine), and high levels of GHB (γ-hydroxybutyric acid) in addition to methadone and buprenorphine were investigated. Reported findings of hepatitis, portal lymphadenopathy, recent injection marks, drug user's equipment, and numbers of significant pathological conditions were registered and analyzed according to cases positive for opiates, opioids (OPs), and central nervous system (CNS)-stimulating illicit drugs, respectively. Of the selected cases, 1305 were positive for one or more opiate or OP. Cases positive for OPs had significantly more findings of noninfectious pathological conditions. Hepatitis, portal lymphadenopathy, recent injections marks findings of drug user's equipment were all findings found more frequently among the opiate OP-positive individuals. Portal lymphadenopathy was significantly more often found in cases with hepatitis than in cases with other or no infection. In the population positive for CNS stimulants, hepatitis recent injection marks were more frequent findings than in the CNS stimulant-negative group, irrespective of whether they were opiate OP positive or negative.

Awareness of and attitudes toward direct-to-consumer prescription drug advertising among young adults.

PubMed

Alperstein, Neil M

2014-01-01

This study examines awareness and knowledge of and attitudes toward direct-to-consumer (DTC) prescription drug advertising among young adults between 18 and 24 years of age. The study finds that young adults are not as aware of prescription drug advertising as older consumers, however, they are aware of specific heavily advertised drugs, especially those for allergy medications, birth control, and sleep aids. Young adults hold mixed to negative views about advertising in general, and they do not view DTC prescription drug advertising as a beneficial source of information, nor do they believe such advertising serves to educate consumers.

'Silk Road', the virtual drug marketplace: a single case study of user experiences.

PubMed

Van Hout, Marie Claire; Bingham, Tim

2013-09-01

The online promotion of 'drug shopping' and user information networks is of increasing public health and law enforcement concern. An online drug marketplace called 'Silk Road' has been operating on the 'Deep Web' since February 2011 and was designed to revolutionise contemporary drug consumerism. A single case study approach explored a 'Silk Road' user's motives for online drug purchasing, experiences of accessing and using the website, drug information sourcing, decision making and purchasing, outcomes and settings for use, and perspectives around security. The participant was recruited following a lengthy relationship building phase on the 'Silk Road' chat forum. The male participant described his motives, experiences of purchasing processes and drugs used from 'Silk Road'. Consumer experiences on 'Silk Road' were described as 'euphoric' due to the wide choice of drugs available, relatively easy once navigating the Tor Browser (encryption software) and using 'Bitcoins' for transactions, and perceived as safer than negotiating illicit drug markets. Online researching of drug outcomes, particularly for new psychoactive substances was reported. Relationships between vendors and consumers were described as based on cyber levels of trust and professionalism, and supported by 'stealth modes', user feedback and resolution modes. The reality of his drug use was described as covert and solitary with psychonautic characteristics, which contrasted with his membership, participation and feelings of safety within the 'Silk Road' community. 'Silk Road' as online drug marketplace presents an interesting displacement away from 'traditional' online and street sources of drug supply. Member support and harm reduction ethos within this virtual community maximises consumer decision-making and positive drug experiences, and minimises potential harms and consumer perceived risks. Future research is necessary to explore experiences and backgrounds of other users. Copyright © 2013

Knowledge of AIDS and HIV transmission among drug users in Rio de Janeiro, Brazil

PubMed Central

2011-01-01

Background Proper knowledge of HIV transmission is not enough for people to adopt protective behaviors, but deficits in this information may increase HIV/AIDS vulnerability. Objective To assess drug users' knowledge of HIV/AIDS and the possible association between knowledge and HIV testing. Methods A Cross-sectional study conducted in 2006/7 with a convenience sample of 295 illicit drug users in Rio de Janeiro, assessing knowledge on AIDS/HIV transmission and its relationship with HIV testing. Information from 108 randomly selected drug users who received an educational intervention using cards illustrating situations potentially associated with HIV transmission were assessed using Multidimensional Scaling (MDS). Results Almost 40% of drug users reported having never used condoms and more than 60% reported not using condoms under the influence of substances. Most drug users (80.6%) correctly answered that condoms make sex safer, but incorrect beliefs are still common (e.g. nearly 44% believed HIV can be transmitted through saliva and 55% reported that HIV infection can be transmitted by sharing toothbrushes), with significant differences between drug users who had and who had not been tested for HIV. MDS showed queries on vaginal/anal sex and sharing syringes/needles were classified in the same set as effective modes of HIV transmission. The event that was further away from this core of properly perceived risks referred to blood donation, perceived as risky. Other items were found to be dispersed, suggesting inchoate beliefs on transmission modes. Conclusions Drug users have an increased HIV infection vulnerability compared to the general population, this specific population expressed relevant doubts about HIV transmission, as well as high levels of risky behavior. Moreover, the findings suggest that possessing inaccurate HIV/AIDS knowledge may be a barrier to timely HIV testing. Interventions should be tailored to such specific characteristics. PMID:21324119

Young men who have sex with men (YMSM) are substantially more likely to use illicit drugs and other substances compared to their heterosexual peers. Substance use during adolescence has critical implications for long-term physical and mental health, and among YMSM may lead to HIV infection. The goal of the current study was to describe lifetime and past six month prevalence and patterns of substance use across multiple substances in a community sample of racially-diverse YMSM. Participants were 450 YMSM aged 16-20 living in Chicago and surrounding areas who were recruited beginning December, 2009 using a modified form of respondent driven sampling. Analyses were conducted with multivariate logistic regression and latent class analysis (LCA). Prevalence of substance use was high in this sample of majority racial minority YMSM, and only 17.6% reported no substance use during the past six months. Black YMSM had lower prevalence of use of all substances except marijuana compared to White YMSM, while Latino YMSM had lower prevalence of alcohol, marijuana, and club drug use. Bisexual YMSM reported higher prevalence of cigarette smoking, stimulant use, and club drug use compared to gay/mostly gay YMSM but lower numbers of bisexual participants limited the ability to detect statistically significant differences. LCA found that YMSM fell into three general categories of substance users: alcohol and marijuana users, polysubstance users, and low marijuana users. Analyses reveal important group differences in prevalence and patterns of substance use in YMSM that have important implications for intervention. Copyright © 2014 Elsevier Ireland Ltd.

Background: Studies on diabetes among illicit drug users are scarce in Finland. This study aimed to describe hospitalization and death due to diabetes among treatment-seeking illicit drug users. Methods: Information of 4817 treatment-seeking drug users (3365 men and 1452 women) aged 11–65 years (mean 24.5 years) was linked to the Finnish national hospital discharge register and the national death registry to identify those clients who were hospitalized or died from diabetes mellitus during 1997–2013. Results: Fifty-three persons (42 men and 11 women) had primary diagnoses of diabetes, with a total of 146 hospitalizations (121 among men and 25 among women). The total length of stay among men (1183 days) far exceeded those of women (138 days). Overall, type 1 diabetes was the main contributor to hospitalizations (67%, n = 98/146). The proportion of Type 1 diabetes with complications was 31% in men (n = 37/121) and 44% in women (n = 11/25). All cases of deaths due to diabetes (n = 7) occurred in men. Conclusion: Diabetes hospitalizations were mainly due to Type 1 diabetes. Longer length of hospital stay was observed in men, and all diabetes deaths occurred among men. Male drug users and drug users in general would require more support to reduce morbidity and mortality due to diabetes.

Objectives. We examined the relation between childhood sexual abuse and injection drug use initiation among young adult injection drug users. Methods. We used mixed effect linear models to compare age at first injection among 2143 young injection drug users by first sexual abuse age categories. Results. The participants were predominantly male (63.3%) and White (52.8%). Mean age and age at first injection were 23.7 and 19.6 years, respectively; 307 participants (14.3%) reported childhood sexual abuse. After adjustment for gender, race/ethnicity, noninjection drug use before first injection drug use, and recruitment site, childhood sexual abuse was independently associated with younger age at first injection. Conclusions. Childhood sexual abuse was associated with earlier initiation of injection drug use. These data emphasize the need to integrate substance abuse prevention with postvictimization services for children and adolescents. PMID:15798133

2013-03-01

Health is a basic human right, and drug use represents a severe influence on people's health. This qualitative study aimed to understand how health professionals in a public health-care team working with drug users in a city of the state of São Paulo, Brazil, perceive the human rights of these users and how these rights are being respected in health care. Data were collected through semistructured interviews with 10 health professionals at the service under analysis. A thematic analysis of the interviews reveals the professionals' difficulty to define the concept of human right and contextualize these rights in their work environment. A deeper understanding of the right to health, however, represents an important premise for a more humanized care practice in health services to drug users.

Drug and alcohol-impaired driving among electronic music dance event attendees.

2006-10-15

Drug-impaired driving has received increased attention resulting from development of rapid drug-screening procedures used by police and state laws establishing per se limits for drug levels in drivers. Venues that host electronic music dance events (EMDEs) provide a unique opportunity to assess drug-impaired driving among a high proportion of young adult drug users. EMDEs are late-night dance parties marked by a substantial number of young adult attendees and elevated drug involvement. No studies to date have examined drug-impaired driving in a natural environment with active drug and alcohol users. Six EMDEs were sampled in San Diego, California, and Baltimore, Maryland. A random sample of approximately 40 attendees per event were administered surveys about alcohol and other drug (AOD) use and driving status, given breath tests for alcohol, and asked to provide oral fluid samples to test for illicit drug use upon entering and exiting the events. Driving status reduced the level of alcohol use (including abstaining) but the impact on drug-taking was not significant. However, 62% of individuals who reported their intention to drive away from the events were positive for drugs or alcohol upon leaving. This suggests that these events and settings are appropriate ones for developing interventions for reducing risks for young adults.

Cannabis use in youth is rising and has been linked to deficits in cognitive functioning. However, cognitive findings have primarily been based on small samples of users seeking treatment, and few studies have evaluated cognition in occasional cannabis users. Here, we examined 4,568 adolescents and young adults (ages 14–21) drawn from the Philadelphia Neurodevelopmental Cohort, a prospective, population-based study. Participants were classified as cannabis Non-Users (n=3,401), Occasional Users (twice per week or less; n=940), or Frequent Users (>3 times per week; n=227). Mixed-model analyses examined main effects of cannabis use and interactions between age and cannabis use on cognitive functioning. There was a significant interaction between cannabis group and age, such that adolescent (but not young adult) Frequent Users performed worse than Non-Users on measures of executive control (p=0.002). Earlier age of cannabis use was associated with worse performance in executive control in Occasional Users (p=0.04). Unexpectedly, Occasional Users exhibited better executive control, memory, and social cognition than Non-Users (ps<.05). Although mild executive control deficits in adolescent frequent users and a relation between early cannabis initiation and cognitive performance are partially consistent with prior research, cognitive deficits were not found in other hypothesized domains in this community-based sample. Moreover, occasional cannabis users displayed equivalent or even slightly better executive control, social cognitive, and memory abilities compared to non-users, suggesting complex relationships between cannabis use and cognition in youth. Longitudinal studies with community samples are needed to identify variables affecting risk and resilience to cognitive deficits associated with cannabis. PMID:28414475

2017-03-01

Substance use and pharmacologic treatment of co-occurring infections such as human immunodeficiency virus (HIV) and hepatitis C virus (HCV) are associated with many adverse consequences including pharmacokinetic and pharmacodynamic drug-drug interactions (DDIs). The National Institute on Drug Abuse sponsored a 2-day conference on DDIs at which clinicians/scientists from government, academia, and the pharmaceutical industry presented the most current research findings to formulate a comprehensive overview of DDIs. Specific topics discussed included drug metabolism; drug interactions between medications used in the treatment of HIV, HCV, and substance use disorders; intrahepatic concentrations and methods of assessment of drugs in liver disease of varying etiologies and degrees of impairment; and minimally invasive sampling techniques for the assessment of intrahepatic drug concentrations, viral replication, and changes in gene expression in response to treatment. Finally, the speakers identified research targets and priorities on DDIs. Areas of emphasis included development of diagnostic assays for drug concentration assessment in different organs, an enhanced understanding of factors responsible for alterations in drug metabolism and excretion, and establishment of clinical trials and work groups to study DDIs. Our long-term objective is to broaden investigation in the field of DDIs in substance users. © 2017, The American College of Clinical Pharmacology.

To understand the perceptions of pharmacy teams about their role in the healthcare assistance challenges and adherence to antiretroviral therapy by injecting drug users living with HIV/AIDS. Qualitative study through focus groups and thematic discourse analysis of pharmacists, technicians and assistants with more than six months of experience with medication supply, in 15 assisting units for STD/AIDS in the city of São Paulo, in 2002. Three groups were formed, totaling 29 participants, originating from 12 out of the 15 existing services, and including 12 university level professionals and 17 high-school level professionals. The groups concluded that the pharmacy has an important role in the antiretroviral drug supply, which is reflected in the treatment adherence, because trust-based relationships can be built up through their procedures. In spite of this, they pointed out that such building-up does not take place through excessively bureaucratic activities. This has negative repercussions for all patients, especially for injecting drug users, considered "difficult people". Such concept sums up their behavior: they are supposed to be confused and incapable to adhere to treatment, and have limited understanding. Staff members, however, affirm they treat these patients equally. They do not realize that, by this acting, the specific needs of injecting drug users may become invisible in the service. There is also the possibility that stigmatizing stereotypes may be created, resulting in yet another barrier to the work on adherence. Although the pharmacy is recommended as a potentially favorable place to listen to and form bonds with users, the results show objective and subjective obstacles to render it suitable for the work on adherence.

2017-04-01

To examine variation in pharmaceutical spending and patient characteristics across prescription drug user groups. British Columbia's population-based linked administrative health and sociodemographic databases (N = 3,460,763). We classified individuals into empirically derived prescription drug user groups based on pharmaceutical spending patterns outside hospitals from 2007 to 2011. We examined variation in patient characteristics, mortality, and health services usage and applied hierarchical clustering to determine patterns of concurrent drug use identifying high-cost patients. Approximately 1 in 20 British Columbians had persistently high prescription costs for 5 consecutive years, accounting for 42 percent of 2011 province-wide pharmaceutical spending. Less than 1 percent of the population experienced discrete episodes of high prescription costs; an additional 2.8 percent transitioned to or from high-cost episodes of unknown duration. Persistent high-cost users were more likely to concurrently use multiple chronic medications; episodic and transitory users spent more on specialized medicines, including outpatient cancer drugs. Cluster analyses revealed heterogeneity in concurrent medicine use within high-cost groups. Whether low, moderate, or high, costs of prescription drugs for most individuals are persistent over time. Policies controlling high-cost use should focus on reducing polypharmacy and encouraging price competition in drug classes used by ordinary and high-cost users alike. © 2016 The Authors.

Purpose Examine the severity of club drug dependence and perceived need for treatment, and further identify their determinants among a sample of club drug users in Shanghai, China. Methods 276 club drug users were recruited using respondent-driven sampling (RDS). Severity of dependence on club drugs was measured using the Severity of Dependence Scale (SDS). Results 69.9% reported dependence on club drugs (i.e., SDS≥4) and 36.6% reported severe dependence (i.e., SDS≥6). One eighth (12.7%) perceived need for drug treatment. Severe dependence on club drugs was more likely among those who reported recent use of ecstasy and those who had more depressive symptoms, but less likely among those reporting recent use of methamphetamine. Perceived need for treatment was more likely among those who lived with a spouse or boy/girlfriend, but less likely among those had prior drug treatment experience and more severe club drug dependence. Conclusions Our findings suggest that educational activities should be implemented to raise public awareness about the powerful addictive properties of club drugs, along with efforts to reduce stigma towards drug abuse and psychiatric disorders. Programs to motivate drug users to seek treatment and encourage treatment linkage are urgently needed. PMID:23715971

Although confinement in drug detoxification ("detox") and re-education through labor (RTL) centers is the most common form of treatment for drug dependence in China, little has been published about the experience of drug users in such settings. We conducted an assessment of the impact of detention on drug users' access to HIV prevention and treatment services and consequent threats to fundamental human rights protections. Chinese government HIV and anti-narcotics legislation and policy documents were reviewed, and in-depth and key informant interviews were conducted with 19 injection drug users (IDUs) and 20 government and nongovernmental organization officials in Nanning and Baise, Guangxi Province. Significant contradictions were found in HIV and antinarcotics policies, exemplified by the simultaneous expansion of community-based methadone maintenance therapy and the increasing number of drug users detained in detox and RTL center facilities. IDU study participants reported, on average, having used drugs for 14 y (range 8-23 y) and had been confined to detox four times (range one to eight times) and to RTL centers once (range zero to three times). IDUs expressed an intense fear of being recognized by the police and being detained, regardless of current drug use. Key informants and IDUs reported that routine HIV testing, without consent and without disclosure of the result, was the standard policy of detox and RTL center facilities, and that HIV-infected detainees were not routinely provided medical or drug dependency treatment, including antiretroviral therapy. IDUs received little or no information or means of HIV prevention, but reported numerous risk behaviors for HIV transmission while detained. Legal and policy review, and interviews with recently detained IDUs and key informants in Guangxi Province, China, found evidence of anti-narcotics policies and practices that appear to violate human rights and imperil drug users' health.

Compulsory drug detention is the most frequent way to control drug use in China; however, it has often been criticized. This qualitative study aimed to investigate abstinence self-efficacy and its sources of drug users in a compulsory male drug detention center in Shanghai, China, and the attitudes of the drug users to this form of rehabilitation. Thirty-six participants were interviewed (semi-structured, in depth) about their history of drug use and rehabilitation, self-evaluation of addiction, motivations to abstain, plans for the future and attitudes toward rehabilitation. A thematic analysis was undertaken of the transcripts with responses to interview questions being coded for content. Two main types of self-efficacy were found - "overconfidence" (n = 16) and "helplessness" (n = 17). Overconfident participants underestimated their levels of addiction, overestimated their self-control and held external motivations and attributions. In contrast, helpless participants overestimated their levels of addiction, underestimated their self-control and had internal motivations and attributions. Compared to overconfident participants, helpless participants had more relapse history, and were more inclined to interpret relapse as a failure and attribute relapse to themselves. More helpless participants were abandoned by their family members, and received blame from the family members instead of encouragement, but their family members motivated them to abstain. Helpless participants experienced more negative emotions and had worse physical status. They said compulsory detention was a strong support for them and was the most effective way to abstain; while overconfident participants said compulsory detention was not necessary and not useful. It is important to increase the motivation of overconfident drug users and the perceived control of helpless drug users. Compulsory drug detention has strengths in supporting drug users who feel helpless to resist drug use

User surveys indicate that expectations of higher drug purity are a key reason for cryptomarket use. In 2014-2015, Spain's NGO Energy Control conducted a 1-year pilot project to provide a testing service to cryptomarket drug users using the Transnational European Drug Information (TEDI) guidelines. In this paper, we present content and purity data from the trial. 219 samples were analyzed by gas chromatography associated with mass spectrometry (GC/MS). Users were asked to report what substance they allegedly purchased. 40 different advertised substances were reported, although 77.6% were common recreational drugs (cocaine, MDMA, amphetamines, LSD, ketamine, cannabis). In 200 samples (91.3%), the main result of analysis matched the advertised substance. Where the advertised compound was detected, purity levels (m±SD) were: cocaine 71.6±19.4%; MDMA (crystal) 88.3±1.4%; MDMA (pills) 133.3±38.4mg; Amphetamine (speed) 51.3±33.9%; LSD 123.6±40.5μg; Cannabis resin THC: 16.5±7.5% CBD: 3.4±1.5%; Ketamine 71.3±38.4%. 39.8% of cocaine samples contained the adulterant levamisole (11.6±8%). No adulterants were found in MDMA and LSD samples. The largest collection of test results from drug samples delivered from cryptomarkets are reported in this study. Most substances contained the advertised ingredient and most samples were of high purity. The representativeness of these results is unknown. Copyright © 2016 Elsevier B.V. All rights reserved.

MONITORING POTENTIAL DRUG INTERACTIONS AND REACTIONS VIA NETWORK ANALYSIS OF INSTAGRAM USER TIMELINES.

Correia, Rion Brattig; Li, Lang; Rocha, Luis M

2016-01-01

Much recent research aims to identify evidence for Drug-Drug Interactions (DDI) and Adverse Drug reactions (ADR) from the biomedical scientific literature. In addition to this "Bibliome", the universe of social media provides a very promising source of large-scale data that can help identify DDI and ADR in ways that have not been hitherto possible. Given the large number of users, analysis of social media data may be useful to identify under-reported, population-level pathology associated with DDI, thus further contributing to improvements in population health. Moreover, tapping into this data allows us to infer drug interactions with natural products-including cannabis-which constitute an array of DDI very poorly explored by biomedical research thus far. Our goal is to determine the potential of Instagram for public health monitoring and surveillance for DDI, ADR, and behavioral pathology at large. Most social media analysis focuses on Twitter and Facebook, but Instagram is an increasingly important platform, especially among teens, with unrestricted access of public posts, high availability of posts with geolocation coordinates, and images to supplement textual analysis. Using drug, symptom, and natural product dictionaries for identification of the various types of DDI and ADR evidence, we have collected close to 7000 user timelines spanning from October 2010 to June 2015.We report on 1) the development of a monitoring tool to easily observe user-level timelines associated with drug and symptom terms of interest, and 2) population-level behavior via the analysis of co-occurrence networks computed from user timelines at three different scales: monthly, weekly, and daily occurrences. Analysis of these networks further reveals 3) drug and symptom direct and indirect associations with greater support in user timelines, as well as 4) clusters of symptoms and drugs revealed by the collective behavior of the observed population. This demonstrates that Instagram

A study was conducted to examine the travel experiences of a community sample of 160 drug users and 44 non-users recruited as part of a study of HIV risk. Of the sample, 47% (96/204) reported intercity travel in the previous ten years. Results showed that men were more likely to travel than women, Anglos more than minorities, and young persons more than old. When travellers testing HIV-seropositive (n = 13) were compared with seronegative travellers, HIV-positive travellers reported more sex while travelling than HIV-negative persons, but virtually all of the difference reported involved sex with condoms. There were no significant differences in sex risk behaviours while travelling between drug users and non-drug users, or in sex risk behaviors between drug injectors and non-injectors. Travellers had fewer injection partners while travelling than they had while at home. There was also a significant difference in number of sex partners with whom a condom was not used, with fewer sex partners while travelling.

To assess the compliance with the isotretinoin Pregnancy Prevention Programme (PPP) by evaluating the use of prescribed contraceptives among isotretinoin users. The PPP contains a requirement for the use of contraceptive methods for women of childbearing potential. A drug utilisation study was performed using data from a drug prescription database (containing Dutch community pharmacy data) covering a population of 500 000 patients. Contraceptive use in female isotretinoin users and in a reference group of female non-isotretinoin users (aged 15-49 years) was compared using data from 1999 until 2006 in 2-year periods. Descriptive statistics were used. Of the female isotretinoin users (n = 651), 52%-54% filled prescriptions on contraceptives in strict accordance to the PPP, used before, during, and after discontinuation of isotretinoin, compared with 39%-46% in the reference group. A more liberal approach of a minimum of one prescription for a contraceptive method showed 61%-64% use of contraceptives among isotretinoin users. Similar patterns were seen when data were broken down in age groups. Furthermore, a higher proportion of female patients using isotretinoin prescribed by general practitioners used prescribed contraceptives compared with those receiving isotretinoin by specialists. Compliance with the contraceptive use according to a PPP for a teratogenic drug such as isotretinoin is 52%-64%, which is lower than anticipated. Reasons for the low compliance will need to be clarified before further measures can be taken. Copyright © 2012 John Wiley & Sons, Ltd.

Parental substance use is a major risk factor for child development, heightening the risk of drug problems in adolescence and young adulthood, and exposing offspring to several types of traumatic events. First, prenatal drug exposure can be considered a form of trauma itself, with subtle but long-lasting sequelae at the neuro-behavioral level. Second, parents' addiction often entails a childrearing environment characterized by poor parenting skills, disadvantaged contexts and adverse childhood experiences (ACEs), leading to dysfunctional outcomes. Young adults born from/raised by parents with drug problems and diagnosed with a Substance Used Disorder (SUD) themselves might display a particularly severe condition in terms of cognitive deficits and impaired personality function. This preliminary study aims to investigate the role of early exposure to drugs as a traumatic event, capable of affecting the psychological status of young drug addicts. In particular, it intends to examine the neuropsychological functioning and personality profile of young adults with severe SUDs who were exposed to drugs early in their family context. The research involved three groups, each consisting of 15 young adults (aged 18–24): a group of inpatients diagnosed with SUDs and exposed to drugs early, a comparison group of non-exposed inpatients and a group of non-exposed youth without SUDs. A neuropsychological battery (Esame Neuropsicologico Breve-2), an assessment procedure for personality disorders (Shedler-Westen Assessment Procedure-200) and the Symptom CheckList-90-Revised were administered. According to present preliminary results, young drug addicts exposed to drugs during their developmental age were characterized by elevated rates of neuropsychological impairments, especially at the expense of attentive and executive functions (EF); personality disorders were also common but did not differentiate them from non-exposed youth with SUDs.

Illicit drug users account for the majority of cases of HCV infection in the developed world, but few have received treatment. We evaluated barriers to initiating HCV treatment -- including general treatment willingness -- and factors associated with these among HCV infected illicit drug users. Participants were recruited via convenience sampling from two community clinics in Canada. Individuals age >18 years with a history of illicit drug use completed interviewer-administered surveys. Those reporting positive HCV testing underwent additional questioning on willingness, uptake and barriers to treatment for HCV. Of 188 HCV positive illicit drug users, 16% (n=30) had received treatment for HCV. Factors associated with a decreased treatment uptake included current heroin use and HIV/HCV co-infection. Among those not having received therapy, 77% (117/153) indicated a willingness to receive HCV treatment. Factors associated with treatment willingness included not being infected with HIV, having not recently used drugs by injection and having reported physical health problems. Among those not having sought HCV treatment (n=107), the major reasons for not doing so were: lack of information about HCV or knowledge that treatment was available (23%), the absence of symptoms (20%) and the perceived side effects of treatment (14%). Among illicit drug users attending inner city clinics, we have observed a low uptake of HCV treatment, but a high willingness to receive therapy. An increased focus on improving education about the long-term consequences of HCV and the availability of effective treatment are important components for expanding HCV treatment among illicit drug users.

This article presents the development of a theory- and evidence-based AIDS prevention program targeting Dutch drug users and aimed at promoting condom use. The emphasis is on the development of the program using a five-step intervention development protocol called intervention mapping (IM). Preceding Step 1 of the IM process, an assessment of the HIV problem among drug users was conducted. The product of IM Step 1 was a series of program objectives specifying what drug users should learn in order to use condoms consistently. In Step 2, theoretical methods for influencing the most important determinants were chosen and translated into practical strategies that fit the program objectives. The main strategy chosen was behavioral journalism. In Step 3, leaflets with role-model stories based on authentic interviews with drug users were developed and pilot tested. Finally, the need for cooperation with program users is discussed in IM Steps 4 and 5.

Deficits in the communication and identifying of feelings are usually observed in substance abuse. Research in several countries has reported sensation seeking and alexithymia implication in addiction. According to a cognitive-developmental model of emotional experience proposed, alexithymia is a deficit in the cognitive processing of emotion that can be seen as an impairment in the ability to consciously experience feeling in the context of autonomic activation indicate of emotional arousal. The primary objective of this study was to identify certain personality dimensions linked with emotions' regulation, i.e. Zuckerman's sensation seeking, alexithymia, and emotional awareness in ecstasy and cocaine users at techno parties. Subjects were divided in two groups: 37 male ecstasy or cocaine abusers, and 37 male non-drug users. We hypothesized that ecstasy and cocaine users would exhibit high levels of sensation seeking (high level of sensation seeking,), and emotional dysregulation (high level of alexithymia and depression, low level of emotional awareness). The methodology comprised a questionnaire developed for the study, designed to record sociodemographic data and evaluate psychoactive substance use, the MlINI (mini international psychiatric interview), the Zuckerman 40-item Sensation Seeking Scale (SSS-IV), the Toronto Alexithymia Scale (TAS-20), the Levels of Emotional Awareness Scale (LEAS), and the Beck Depression Inventory (BDI-13). Subjects were recruited during rave-parties. The results showed significantly higher sensation seeking scores for ecstasy and cocaine users for the score total and the disinhibition and experience seeking subdimensions. Ecstasy and cocaine abusers exhibited higher TAS-20 and BDI-13 scores and lower levels of emotional awareness than non-drug users. No correlation between the TAS-20 and depression symptomatology emerged. No significant correlations were found between LEAS and TAS-20. These results provide new elements concerning

Objective: To compare the prevalence of HIV infection and its risk factors among Chinese and Burmese drug users living in Dehong Prefecture, Yunnan Province. Methods: We obtained plasma specimens and gathered demographic data from 7 867 drug users with Chinese or Burmese nationality attending rehabilitation clinics in Dehong Prefecture from October 2014 to September 2015. Of these, 7 756 individuals who gave valid questionnaire responses, including 5 389 Chinese and 2 367 Burmese, were enrolled in the study after giving informed consent. We used the Chi-squared test to compare the demographic characteristics and HIV prevalence between the Chinese and Burmese drug users. Logistic regression was then used to identify risk factors for HIV infection. Results: The HIV infection rate of 7 756 subjects (aged (35.45 ± 10.91) years old) was 7.18%, in which Burmese with higher HIV infection rate (9.38%, 222/2 367) than Chinese (6.22%, 335/5 389) (χ 2 =24.21, P <0.001). In chinese drug users, OR (95% CI ) of HIV infection of those aged 25-34 years old, 35-44 years old and ≥45 years old were 2.88 (1.46-5.69), 5.72 (2.87-11.40) and 3.48 (1.66-7.27),compared with those aged below 25 years;Compared with married participants, OR (95% CI ) of those unmarried and divorced were 1.44 (1.08-1.93) and 1.56 (1.09-2.24); Jingpo drug users were 1.47 (1.07-2.04) times to get HIV infection,compared with Han ethnicity; OR (95% CI ) of HIV infection for IDUs was 11.48 (9.73-16.01) compared with NIDUs.In Burmese drug users, OR (95% CI ) of HIV infection for females was 0.50 (0.26-0.93) compared with men;Compared with those aged below 25 years,those aged 25-34,35-44 and ≥45 years had OR (95% CI ) of 1.82 (1.18-2.77), 2.90 (1.82-4.62) and 2.31 (1.24-4.30), respectively; OR (95% CI ) of Jingpo participants was 2.22 (1.44-3.41) compared with Han nationality; OR (95% CI ) of HIV infection for IDUs was 10.61 (7.68-14.64) compared with NIDUs.

This qualitative study of travel-related risk behaviours of Slovene injection drug users was based on interviews with individuals enrolled in drug addiction treatment programmes run by three regional centres for prevention and treatment of drug addiction. The primary objective of the study was to analyse behaviour patterns and practices of injection drug users during travel. Methods Travel-related problems of Slovene injection drug users were identified on the basis of data obtained by 25 in-depth interviews. A semi-structured questionnaire with 13 open-ended questions was developed after a preliminary study and review of the literature, and on the basis of experience with the treatment of drug addiction in Slovenia. Results The sample comprised 25 individuals, 18 men and seven women, aged 25 to 53 years. The interviews were 10 to 30 minutes long. The results obtained were presented as identified risk behaviours. Five categories were generated, providing information on the following topics: procurement of illicit drugs, criminal acts/environment, HIV and hepatitis B and C infections, storage and transport of substitution medication and pre-travel health protection. The first three categories comprise the injection drug users' risk behaviours that are most frequently explored in the literature. The other two categories - storage and transport of medication across the border and pre-travel health protection - reflect national specificities and the effectiveness of substitution treatment programmes. The majority of participants denied having shared needles and other injecting equipment when travelling. Participants who had no doctor's certificate had recourse to various forms of risk behaviour, finding a number of ways to hide the medication at the border. Conclusion This qualitative study provides insight into potential travel-related risk behaviour of injection drug users from two Slovene regions - central and coastal.

This study reviewed the perceptions and strategies of drug users and nurses with regard to pain management in acute care settings. Drug users present unique challenges in acute care settings with pain management noted to be at best suboptimal, at worst non-existent. Little is known about why and specifically how therapeutic effectiveness is compromised. Qualitative: constructivist grounded theory. A constructivist grounded theory approach incorporating a constant comparative method of data collection and analysis was applied. The data corpus comprised interviews with drug users (n = 11) and five focus groups (n = 22) of nurses and recovering drug users. Moral relativism as the core category both represents the phenomenon and explains the basic social process. Nurses and drug users struggle with moral relativism when addressing the issue of pain management in the acute care setting. Drug users lay claim to expectations of compassionate care and moralise via narration. Paradoxically, nurses report that the caring ideal and mutuality of caring are diminished. Drug users' individual sensitivities, anxieties and felt stigma in conjunction with opioid-induced hyperalgesia complicate the processes. Nurses' and hospitals' organisational routines challenge drug user rituals and vice versa leading both protagonists to become disaffected. Consequently, key clinical issues such as preventing withdrawal and managing pain are left unaddressed and therapeutic effectiveness is compromised. This study provides a robust account of nurses' and drug users' struggle with pain management in the acute care setting. Quick technological fixes such as urine screens, checklists or the transient effects of (cognitive-based) education (or training) are not the answer. This study highlights the need for nurses to engage meaningfully with this perceptibly 'difficult' group of patients. The key aspects likely to contribute to problematic interactions with this patient cohort are outlined so that

BACKGROUND: Young Indigenous people, particularly those involved in the child welfare system, those entrenched in substance use and those living with HIV or hepatitis C, are dying prematurely. We report mortality rates among young Indigenous people who use drugs in British Columbia and explore predictors of mortality over time. METHODS: We analyzed data collected every 6 months between 2003 and 2014 by the Cedar Project, a prospective cohort study involving young Indigenous people who use illicit drugs in Vancouver and Prince George, BC. We calculated age-standardized mortality ratios using Indigenous and Canadian reference populations. We identified predictors of mortality using time-dependent Cox proportional hazard regression. RESULTS: Among 610 participants, 40 died between 2003 and 2014, yielding a mortality rate of 670 per 100 000 person-years. Young Indigenous people who used drugs were 12.9 (95% confidence interval [CI] 9.2–17.5) times more likely to die than all Canadians the same age and were 7.8 (95% CI 5.6–10.6) times more likely to die than Indigenous people with Status in BC. Young women and those using drugs by injection were most affected. The leading causes of death were overdose (n = 15 [38%]), illness (n = 11 [28%]) and suicide (n = 5 [12%]). Predictors of mortality included having hepatitis C at baseline (adjusted hazard ratio [HR] 2.76, 95% CI 1.47–5.16), previous attempted suicide (adjusted HR 1.88, 95% CI 1.01–3.50) and recent overdose (adjusted HR 2.85, 95% CI 1.00–8.09). INTERPRETATION: Young Indigenous people using drugs in BC are dying at an alarming rate, particularly young women and those using injection drugs. These deaths likely reflect complex intersections of historical and present-day injustices, substance use and barriers to care. PMID:29109208

Personal networks are significant social spaces to spread of HIV or other blood-borne infections among hard-to-reach population, viz., injecting drug users, female sex workers, etc. Sharing of infected needles or syringes among drug users is one of the major routes of HIV transmission in Manipur, a high HIV prevalence state in India. This study was carried out to describe the network characteristics and recruitment patterns of injecting drug users and to assess the association of personal network with injecting risky behaviors in Manipur. A total of 821 injecting drug users were recruited into the study using respondent-driven sampling (RDS) from Bishnupur and Churachandpur districts of Manipur; data on demographic characteristics, HIV risk behaviors, and network size were collected from them. Transition probability matrices and homophily indices were used to describe the network characteristics, and recruitment patterns of injecting drug users. Univariate and multivariate binary logistic regression models were performed to analyze the association between the personal networks and sharing of needles or syringes. The average network size was similar in both the districts. Recruitment analysis indicates injecting drug users were mostly engaged in mixed age group setting for injecting practice. Ever married and new injectors showed lack of in-group ties. Younger injecting drug users had mainly recruited older injecting drug users from their personal network. In logistic regression analysis, higher personal network was found to be significantly associated with increased likelihood of injecting risky behaviors. Because of mixed personal network of new injectors and higher network density associated with HIV exposure, older injecting drug users may act as a link for HIV transmission or other blood-borne infections to new injectors and also to their sexual partners. The information from this study may be useful to understanding the network pattern of injecting drug users

Drug hypersensitivity is defined as any unfavorable reaction that occurs after the administration of any drug. It may or may not be mediated by the involvement of the immune system. Epidemiological data related to drug hypersensitivity reactions in our country are scarce. To determine the prevalence of drug hypersensitivity in a group of young adults, as well as to identify associated factors. A structured questionnaire was applied to young people aged 18 to 25 years. The instrument was oriented to identify reactions of drug hypersensitivity, as well as the most prevalent drugs involved. In addition, a personal and family history of atopic diseases was included. Analysis for associations between variables was been done through logistic regression. The prevalence of drug hypersensitivity reactions was 12% (144 of 1,200). The antibiotics were the agents most related to hypersensitivity reactions (9.8%) followed by nonsteroidal anti-inflammatory drugs (1.6%). Factors associated with drug hypersensitivity were a personal history of asthma, odds ratio (OR) 3.15 (95% confidence interval [CI], 1.44-6.91), maternal and paternal history of drug hypersensitivity, OR 2.33 (95% CI, 1.21-4.48) and OR 3.11 (95% CI, 1.22-7.92), respectively. The results of this research show that drug hypersensitivity in young adults is a highly prevalent event and it is associated with personal history of asthma and history of drug hypersensitivity in parents.

Background Drug-impaired driving has received increased attention resulting from development of rapid drug-screening procedures used by police and state laws establishing per se limits for drug levels in drivers. Venues that host electronic music dance events (EMDEs) provide a unique opportunity to assess drug-impaired driving among a high proportion of young adult drug users. EMDEs are late-night dance parties marked by a substantial number of young adult attendees and elevated drug involvement. No studies to date have examined drug-impaired driving in a natural environment with active drug and alcohol users. Methods Six EMDEs were sampled in San Diego, California, and Baltimore, Maryland. A random sample of approximately 40 attendees per event were administered surveys about alcohol and other drug (AOD) use and driving status, given breath tests for alcohol, and asked to provide oral fluid samples to test for illicit drug use upon entering and exiting the events. Results Driving status reduced the level of alcohol use (including abstaining) but the impact on drug-taking was not significant. However, 62% of individuals who reported their intention to drive away from the events were positive for drugs or alcohol upon leaving. This suggests that these events and settings are appropriate ones for developing interventions for reducing risks for young adults. PMID:16675160

Background This paper examines client/staff conflict and user involvement in drug misuse treatment decision-making. Methods Seventy-nine in-depth interviews were conducted with new treatment clients in two residential and two community drug treatment agencies. Fifty-nine of these clients were interviewed again after twelve weeks. Twenty-seven interviews were also conducted with staff, who were the keyworkers for the interviewed clients. Results Drug users did not expect, desire or prepare for conflict at treatment entry. They reported few actual conflicts within the treatment setting, but routinely discussed latent conflicts – that is, negative experiences and problematic aspects of current or previous treatment that could potentially escalate into overt disputes. Conflict resulted in a number of possible outcomes, including the premature termination of treatment; staff deciding on the appropriate outcome; the client appealing to the governance structure of the agency; brokered compromise; and staff skilfully eliciting client consent for staff decisions. Conclusion Although the implementation of user involvement in drug treatment decision-making has the potential to trigger high levels of staff-client conflict, latent conflict is more common than overt conflict and not all conflict is negative. Drug users generally want to be co-operative at treatment entry and often adopt non-confrontational forms of covert resistance to decisions about which they disagree. Staff sometimes deploy user involvement as a strategy for managing conflict and soliciting client compliance to treatment protocols. Suggestions for minimising and avoiding harmful conflict in treatment settings are given. PMID:18837989

To measure the prevalence of 3,4-methylenedioxymethamphetamine (MDMA) and other drug use in young males entering compulsory military service in Asturias (northern Spain) and to define trends in MDMA use in this group during the period from 1995 to 1999. We also sought to determine whether MDMA users have distinct personality features or higher levels of sensation seeking. 3,634 conscripts [mean age (SD) = 20.19 years (2.52)] who entered military service during the period between 1995 and 1999 were evaluated using the World Health Organization (WHO) questionnaire for drug consumption, the Eysenck Personality Questionnaire-A (EPQ-A), and the Zuckerman Sensation Seeking Scale. The prevalence of lifetime, previous year and previous month MDMA use among military recruits between 1995 and 1999 was 10.9, 7.8 and 4.5%, ranking fifth among illicit drugs ever used. Once individuals used MDMA for the first time, they were likely to use it again, with 71% of individuals who had ever used MDMA reporting that they had used it during the past year (ranking second only to hallucinogens), and 41% reporting having used it in the last month. Compared to recruits who had never used MDMA (but who may have used other illicit drugs), MDMA users had a more extensive drug abuse history. Recruits who had used MDMA during the year prior to study had significantly higher scores on the Neuroticism and Psychoticism Subscales of the EPQ-A, and reported higher levels of sensation seeking.

The Prescription Drug User Fee Act: Cause for Concern?

PubMed

Gabay, Michael

2018-04-01

The Prescription Drug User Fee Act (PDUFA) was originally enacted into law in 1992. PDUFA provides the Food and Drug Administration (FDA) with needed revenue in the form of various fees paid by drug and biologic manufacturers. The FDA utilizes this revenue to streamline the review and approval process for medications. Since the enactment of PDUFA, the median approval time for priority new drug applications and biologics license applications has reduced significantly. The FDA views PDUFA as a successful program that provides a consistent revenue stream to the agency, improves access to medications for patients, and allows industry to have a more predictable product review timeline. However, critics of PDUFA cite concerns including the potential for a lack of FDA independence and medication safety issues involving drugs approved after the existence of PDUFA.

MONITORING POTENTIAL DRUG INTERACTIONS AND REACTIONS VIA NETWORK ANALYSIS OF INSTAGRAM USER TIMELINES

Much recent research aims to identify evidence for Drug-Drug Interactions (DDI) and Adverse Drug reactions (ADR) from the biomedical scientific literature. In addition to this “Bibliome”, the universe of social media provides a very promising source of large-scale data that can help identify DDI and ADR in ways that have not been hitherto possible. Given the large number of users, analysis of social media data may be useful to identify under-reported, population-level pathology associated with DDI, thus further contributing to improvements in population health. Moreover, tapping into this data allows us to infer drug interactions with natural products—including cannabis—which constitute an array of DDI very poorly explored by biomedical research thus far. Our goal is to determine the potential of Instagram for public health monitoring and surveillance for DDI, ADR, and behavioral pathology at large. Most social media analysis focuses on Twitter and Facebook, but Instagram is an increasingly important platform, especially among teens, with unrestricted access of public posts, high availability of posts with geolocation coordinates, and images to supplement textual analysis. Using drug, symptom, and natural product dictionaries for identification of the various types of DDI and ADR evidence, we have collected close to 7000 user timelines spanning from October 2010 to June 2015. We report on 1) the development of a monitoring tool to easily observe user-level timelines associated with drug and symptom terms of interest, and 2) population-level behavior via the analysis of co-occurrence networks computed from user timelines at three different scales: monthly, weekly, and daily occurrences. Analysis of these networks further reveals 3) drug and symptom direct and indirect associations with greater support in user timelines, as well as 4) clusters of symptoms and drugs revealed by the collective behavior of the observed population. This demonstrates that

The purpose of the study was to estimate the number of injection drug users infected with the human immunodeficiency virus (HIV) in Bangkok to allow planning for health services for this population. A two-sample capture-recapture method was used. The first capture listed all persons on methadone treatment for opiate addiction from April 17 through May 17, 1991, at 18 facilities in Bangkok. The second capture involved urine testing of persons held at 72 Bangkok police stations from June 3 through September 30, 1991. Persons whose urine tests were positive for opiate metabolites or methadone were included on the second list. The first capture comprised 4064 persons and the recapture 1540 persons. There were 171 persons included on both lists, yielding an estimate of 36,600 opiate users in Bangkok. Existing data indicate that 89% of opiate users in Bangkok inject drugs and that about one third are infected with HIV, yielding an estimate of approximately 12,000 HIV-infected injection drug users in Bangkok in 1991. During the 1990s the number of cases of acquired immunodeficiency syndrome (AIDS) and other HIV-related diseases, including tuberculosis, in the population of HIV-infected injection drug users in Bangkok will increase dramatically, placing new demands on existing health care facilities. The capture-recapture method may be useful in estimating difficult-to-count populations, including injection drug users.

Deportees are a hidden yet highly vulnerable and numerous population. Significantly, little data exists about the substance use and deportation experiences of Mexicans deported from the United States. This pilot qualitative study describes illicit drug use behaviors among 24 Mexico-born male injection drug users (IDUs), ≥ 18 years old, residing in Tijuana, Mexico who self-identified as deportees from the United States. In-person interviews were conducted in Tijuana, Mexico in 2008. Content analysis of interview transcripts identified major themes in participants' experiences. Few participants had personal or family exposures to illicit drugs prior to their first U.S. migration. Participants reported numerous deportations. Social (i.e., friends/family, post-migration stressors) and environmental factors (e.g., drug availability) were perceived to contribute to substance use initiation in the U.S. Drugs consumed in the United States included marijuana, heroin, cocaine, methamphetamine, and crack. More than half of men were IDUs prior to deportation. Addiction and justice system experiences reportedly contributed to deportation. After deportation, several men injected new drugs, primarily heroin or methamphetamine, or a combination of both drugs. Many men perceived an increase in their substance use after deportation and reported shame and loss of familial social and economic support. Early intervention is needed to stem illicit drug use in Mexican migrant youths. Binational cooperation around migrant health issues is warranted. Migrant-oriented programs may expand components that address mental health and drug use behaviors in an effort to reduce transmission of blood-borne infections. Special considerations are merited for substance users in correctional systems in the United States and Mexico, as well as substance users in United States immigration detention centers. The health status and health behaviors of deportees are likely to impact receiving Mexican

Increased ventral striatal BOLD activity during non-drug reward anticipation in cannabis users.

Nestor, Liam; Hester, Robert; Garavan, Hugh

2010-01-01

Despite an increased understanding of the pharmacology and long-term cognitive effects of cannabis in humans, there has been no research to date examining its chronic effects upon reward processing in the brain. Motivational theories regarding long-term drug use posit contrasting predictions with respect to how drug users are likely to process non-drug incentives. The reward deficiency syndrome (RDS) of addiction posits that there are deficits in dopamine (DA) motivational circuitry for non-drug rewards, such that only drugs of abuse are capable of normalizing DA in the ventral striatum (VS). Alternatively, the opponent process theory (OPT) holds that in individuals prone to drug use, there exists some form of mesolimbic hyperactivity, in which there is a bias towards reward-centred behaviour concomitant with impulsivity. The current study examined BOLD responses during reward and loss anticipation and their outcome deliveries in 14 chronic cannabis users and 14 drug-naive controls during a monetary incentive delay (MID) task. Despite no significant behavioural differences between the two groups, cannabis users had significantly more right VS BOLD activity during reward anticipation. Correlation analyses demonstrated that this right VS BOLD response was significantly correlated with life-time use and reported life-time cannabis joints consumed. No correlations between cannabis abstinence and BOLD responses were observed. We also observed a number of group differences following outcome deliveries, most notably hypoactivity in the left insula cortex in response to loss and loss avoidance outcome notifications in the cannabis group. These results may suggest hypersensitivity during instrumental response anticipation for non-drug rewards and a hyposensitivity to loss outcomes in chronic cannabis users; the implications of which are discussed with respect to the potentially sensitizing effects of cannabis for other rewards.

Are users' most recent drug purchases representative?

Various surveys now ask respondents to describe their most recent purchase of illicit drugs, as one mechanism through which market size can be estimated. This raises the question of whether issues surrounding the timing of survey administration might make a sample of most recent purchases differ from a random sample of all purchases. We investigate these issues through a series of questions which ask about the three most recent purchases, and about drug use. Data were drawn from 688 respondents in the Melbourne Injecting Drug User Cohort Study across the period 2008-2013 and 2782 respondents to the Washington Cannabis Consumption Study in 2013. Responses to questions about the most recent purchases were compared to larger subsets of all recent purchases. For heroin, methamphetamine and cannabis no differences were found between the amount spent by participants on their most recent purchase and the average amount spent on three or more recent purchases. There were also no differences concerning the locations and types of deals, and the duration between consecutive cannabis purchases was the same for first and second most recent, and second and third most recent. Asking about the most recent purchase appears to be an economical way to learn about purchases more generally, with little evidence of substantial variation between the most recent purchase and other recent purchases reported by participants. In spite of consistent findings across our two surveys, further replication of the work reported in this paper involving other populations of users is warranted.

Wright, Nat; Oldham, Nicola; Francis, Katharine; Jones, Lesley

2006-01-01

Background Peer use of take home naloxone has the potential to reduce drug related deaths. There appears to be a paucity of research amongst homeless drug users on the topic. This study explores the acceptability and potential risk of peer use of naloxone amongst homeless drug users. From the findings the most feasible model for future treatment provision is suggested. Methods In depth face-to-face interviews conducted in one primary care centre and two voluntary organisation centres providing services to homeless drug users in a large UK cosmopolitan city. Interviews recorded, transcribed and analysed thematically by framework techniques. Results Homeless people recognise signs of a heroin overdose and many are prepared to take responsibility to give naloxone, providing prior training and support is provided. Previous reports of the theoretical potential for abuse and malicious use may have been overplayed. Conclusion There is insufficient evidence to recommend providing "over the counter" take home naloxone" to UK homeless injecting drug users. However a programme of peer use of take home naloxone amongst homeless drug users could be feasible providing prior training is provided. Peer education within a health promotion framework will optimise success as current professionally led health promotion initiatives are failing to have a positive impact amongst homeless drug users.

Drug market policing has been associated with various harms among injection drug users (IDU). However, little is known about instances in which drugs and injecting equipment are confiscated from IDU in the absence of a formal arrest. We examined factors associated with being stopped, searched, or detained by police among participants in the Vancouver Injection Drug Users Study (VIDUS) using logistic regression. We also examined actions taken by study participants immediately following instances in which drugs or syringes were confiscated by police. Among 465 active IDU, 130 (28.0%) reported being detained by police in the last 6 months without being arrested. In multivariate logistic regression analysis, factors associated with being stopped, searched or detained by police included homelessness (Adjusted Odds Ratio [AOR]=3.96, 95% CI: 1.86-8.45), recent incarceration (AOR=3.52, 95% CI: 1.75-7.10), frequent crack use (AOR=2.24, 95% CI: 1.34-3.74), requiring help injecting (AOR=5.20, 95% CI: 1.21-22.39), and lending syringes (AOR=3.18, 95% CI: 1.09-9.30). Of those who reported being detained, 34% participants reported having had drugs confiscated, and 70% of these reported that they immediately acquired more drugs. Fifty-one percent of participants who reported being detained also reported having had syringes confiscated, and of this group, 6% reported immediately borrowing used syringes. Our study demonstrates that the IDU most affected by street-level policing tend to possess various characteristics, such as homelessness, that place them at heightened risk for various adverse health outcomes. Our findings also suggest that the confiscation of drugs and/or needles and syringes through discretionary policing practices have the potential to exacerbate drug market activity or prompt increased syringe borrowing. These findings indicate the need for ongoing evaluation of the public health impacts of discretionary policing approaches.

Objectives. We examined risk factors for syphilis infection among injection drug users in 3 Russian Federation cities, focusing particular attention on the potential roles of gender and sex work. Methods. We conducted a cross-sectional survey of injection drug users in Moscow, Volgograd, and Barnaul, collecting behavioral data and testing for antibodies to Treponema pallidum. Associations between presence of antibodies to T pallidum and covariates were explored. Results. Overall, the prevalence of antibodies to T pallidum was 11% (95% confidence interval=9.7%, 13.1%). Syphilis was associated with involvement in sex work and with gender in Moscow and Barnaul but not in Volgograd. Female injection drug users not involved in sex work were more likely than men to be younger and to have recently begun to inject; female injection drug users involved in sex work were more likely than those not involved in sex work to inject daily. Conclusions. Syphilis transmission dynamics varied by region. Sex work can increase syphilis risk among injection drug users, potentially feeding the momentum of sexually transmitted HIV and syphilis among noninjectors. Targeted interventions are needed to reduce both sexual and injection risk behaviors among injection drug users. PMID:17018827

Polydrug use among club-going young adults recruited through time-space sampling

Though some researchers have indicated club drug users are more likely to be polydrug users, there remains little known about the prevalence and specific combinations of the substances they use. Between 2004-2006, and using time-space sampling, a stratified sample of 400 18-29 year old New York City club-going drug-using young adults were recruited into the Club Drugs and Health Project. Most participants (91.7%) had engaged in polydrug use and 1,670 combinations of drugs were reported. Ecstasy (86.6% of users) and cocaine (85.7% of users) were the two most frequently reported club drugs used in combination with other substances. In terms of poly-club-drug combinations, ecstasy appeared to be the “universal compliment” as this drug was most often cited in combinations with other club drugs (specifically ecstasy + ketamine, ecstasy + cocaine, ecstasy + GHB). Other frequently cited drug combinations included cocaine and marijuana, ecstasy and marijuana, LSD and marijuana, and cocaine and alcohol. These data highlight the need to develop drug health education and prevention messages targeted at polydrug use. PMID:19444726

Fall risk is a critical component of clinical assessment and has not been examined for persons who have injected illicit drugs and are aging. The aim of this study was to test and develop the Fall Risk Model for Injection Drug Users by examining the relationships among injection drug use, chronic venous insufficiency, lower extremity impairments (i.e., decreased ankle range of motion, reduced calf muscle endurance, and leg pain), age and other covariates, and the Tinetti balance and gait total score as a measure of fall risk. A cross-sectional comparative design was used with four crossed factors. Standardized instruments were used to assess the variables. Moderated multiple regression with linear and quadratic trends in age was used to examine the nature of the relationship between the Tinetti balance and gait total and age and the potential moderating role of injection drug use. A prespecified series of models was tested. Participants (n = 713) were men (46.9%) and women with a mean age of 46.26 years and primarily African American (61.7%) in methadone treatment centers. The fall risk of a 48-year-old leg injector was comparable with the fall risk of a 69-year-old who had not injected drugs. Variables were added to the model sequentially, resulting in some lost significance of some when they were explained by subsequent variables. Final significant variables in the model were employment status, number of comorbidities, ankle range of motion, leg pain, and calf muscle endurance. Fall risk was associated with route of drug use. Lower extremity impairments accounted for the effects of injection drug use and chronic venous insufficiency on risk for falls. Further understanding of fall risk in injection users is necessary as they age, attempt to work, and participate in activities.

Prescription opioid use, misuse, and diversion among street drug users in New York City.

PubMed

Davis, W Rees; Johnson, Bruce D

2008-01-01

The use of heroin, cocaine, and other drugs is well researched in New York City, but prescription opioids (POs) have been overlooked. This study documents patterns of PO use, misuse, and diversion among street drug users, and begins to indicate how drug culture practices interact with the legitimate therapeutic goals of PO prescriptions (e.g. pain management). Staff completed interviews inquiring about the reasons for use of POs and illicit drugs with 586 street drug users. Ethnographers wrote extensive field notes about subjects' complex patterns of PO use. Methadone was used (71.9%) and sold (64.7%) at a higher level than OxyContin, Vicodin, and Percocet, used by between 34% and 38% of the users and sold by between 28% and 41% of the sellers. Recent PO use is associated with the recency of using heroin and cocaine (p<.001). Half of the heroin/cocaine sellers sold POs, and one quarter of the PO sellers only sold POs. Subjects were classified into four groups by whether they diverted POs or used POs to relieve pain or withdrawal rather than for euphoria. This classification was associated with frequency of PO use, whether POs were obtained from doctors/pharmacies or from drug dealers and family members, and those mostly likely to use POs for pain and withdrawal. POs are an important component of street drug users' drug-taking regimes, especially those who are Physically Ill Chemical Abusers (PICA). Future research is needed to model PO use, misuse, and diversion among this population.

Driving following illicit drug consumption ('drug-driving') is a potential road safety risk. Roadside drug testing (RDT) is conducted across Australia with the dual aims of prosecuting drivers with drugs in their system and deterring drug-driving. We examined trends over time in self-reported past six-month drug-driving among sentinel samples of regular drug users and assessed the impact of experiences of RDT on drug-driving among these participants. Data from 1913 people who inject drugs (PWID) and 3140 regular psychostimulant users (RPU) who were first-time participants in a series of repeat cross-sectional sentinel studies conducted in Australian capital cities from 2007 to 2013 and reported driving in the past six months were analysed. Trends over time were assessed using the χ 2 test for trend. Multivariable logistic regressions assessed the relationship between experiences of RDT and recent drug-driving, adjusting for survey year, jurisdiction of residence and socio-demographic and drug use characteristics. The percentage of participants reporting recent (past six months) drug-driving decreased significantly over time among both samples (PWID: 83% [2007] vs. 74% [2013], p<0.001; RPU: 72% vs. 56%, p<0.001), but drug-driving remained prevalent. Lifetime experience of RDT increased significantly over time (PWID: 6% [2007] vs. 32% [2013], p<0.001; RPU: 2% vs. 11%, p<0.001). There were no significant associations between experiencing RDT and drug-driving among either PWID or RPU. Although there is some evidence that drug-driving among key risk groups of regular drug users is declining in Australia, possibly reflecting a general deterrent effect of RDT, experiencing RDT appears to have no specific deterrent effect on drug-driving. Further intervention, with a particular focus on changing attitudes towards drug-driving, may be needed to further reduce this practice among these groups. Copyright © 2017 Elsevier Ltd.

Effects of the Affordable Care Act's young adult insurance expansion on prescription drug insurance coverage, utilization, and expenditures.

PubMed

Look, Kevin A; Arora, Prachi

2016-01-01

The US Affordable Care Act (ACA) extended the age of eligibility for young adults to remain on their parents' health insurance plans in order to address the disproportionate number of uninsured young adults in the United States. Effective September 23, 2010, the ACA has required all private health insurance plans to cover dependents until the age of 26. However, it is unknown whether the ACA dependent coverage expansion had an impact on prescription drug insurance or the use of prescription drugs. To evaluate short-term changes in prescription health insurance coverage, prescription drug insurance coverage, prescription drug use, and prescription drug expenditures following implementation of the ACA young adult insurance expansion using national data from 2009 and 2011. Full-year health insurance coverage increased 4.9 percentage points during the study period, which was mainly due to increases in private health insurance among middle- and high-income young adults. In contrast, full-year prescription drug insurance coverage increased 5.5 percentage points and was primarily concentrated among high-income young adults. Although no significant short-term changes in overall prescription drug use were observed, a 30% decrease in out-of-pocket expenditures was seen among young adults. While the main goal of the ACA's young adult insurance expansion was to increase health insurance coverage among young adults, it also had the unintended positive effect of increasing coverage for prescription drug insurance. Additionally, young adults experienced substantial decreases in out-of-pocket spending for prescription drugs. It is important for evaluations of health care policies to assess both intended and unintended outcomes to better understand the implications for the broader health system.

To evaluate the nutritional status of crack users and to analyze its correlation with drug use profiles. Cross-sectional study with 108 crack users. Anthropometric data were assessed through body mass index (BMI) and bioimpedance (BIA) measurements. A blood test to analyze hematocrit, hemoglobin, glucose, and lipid profiles was also performed. Crack use was determined through a standardized interview. Based on BMI and BIA, most individuals were eutrophic (about 70%). Regarding hematological parameters, we found that hemoglobin and hematocrit levels were below normal for 32.4 and 30.6% of patients, respectively. Considering normal parameters, a large part of the sample (60.2%) had low levels of HDL cholesterol and high levels of triglycerides (38%). There were no significant correlations between drug profile and nutritional variables. This is a pioneering study that examines the nutritional status of crack users. Our results showed that most crack users present normal anthropometric findings and the prevalence of underweight is low. However, blood analysis showed changes and a specific type of malnutrition.

BACKGROUND Schizophrenic patients who receive antipsychotic drugs may be highly prone to metabolic disorders such as weight gain, dyslipidemia, and insulin resistance. The objective of the present study was to compare the effect of atypical and conventional antipsychotics on lipid profile. METHODS 128 schizophrenic patients were enrolled into the study. Patients were divided into two groups. One group had received one type of atypical antipsychotic drug, and, the other, one type of conventional antipsychotic drug. They were considered as atypical and conventional groups. Moreover, both groups had not used any other antipsychotic drugs during the past year. Demographic data and food frequency questionnaire were completed by the participants. Serum triglyceride, total cholesterol (TC), high-density lipoprotein and low-density lipoprotein (LDL) cholesterols, and apolipoprotein A and B (Apo B) were tested by blood sample drawing after 12 hours of fasting through the antecubital vein. Student’s t-test was used to compare atypical and conventional groups. RESULTS There was no significant difference in age, gender, duration of illness, period of drug consumption, and age at onset of illness in the two groups. Patients in the atypical group used clozapine and risperidone (46.9%) more than olanzapine. In the conventional group 81.3% of patients used phenothiazines. Comparison between lipid profile in the conventional and atypical groups showed a significantly higher mean in TC (P = 0.01), LDL (P = 0.03), and Apo B (P = 0.01) in conventional group than the atypical group. CONCLUSION In schizophrenic patients, the level of lipid profile had been increased in both atypical and conventional antipsychotic users, especially conventional users, so the effect of antipsychotic drugs should be investigated periodically.

The aim of this study was to co-create of an interview schedule exploring mental health recovery in collaboration with young adult service users. Service user involvement in research has been increasingly recognized as providing a vital authentic insight into mental health recovery. Engagement and collaboration with service users have facilitated the exploration of inaccessible or under-investigated aspects of the lived experience of mental health recovery, not only directing the trajectory of research, but making it relevant to their own contextual experience. A qualitative content analysis framework was employed in the co-creation of a semi-structured interview schedule through an engagement process with service users. Two separate engagement groups took place at the premises of the service user organizations, between January - February 2014. Miles and Huberman's analysis framework was chosen for this phase as it enabled the visual presentation of factors, concepts or variables and the established relationship between them. The lived experience of mental ill health in young adulthood and how this was understood by others was a particularly relevant theme for participants. Further themes were identified between the impact of painful experiences at this developmental life stage leading to a deeper understanding of others through finding meaning in their own mental health recovery journey. Our findings identified that suffering painful experiences is an integral aspect in the process of mental health recovery. This understanding has particular relevance to mental health nursing practice, ensuring the care delivered is cognizant of the suffering or painful experiences that young adults are encountering. © 2017 John Wiley & Sons Ltd.

Increased self-reported impulsivity in methamphetamine users maintaining drug abstinence.

Impulsivity has been proposed as an important factor in the initiation and maintenance of addiction. Indirect evidence suggests that some methamphetamine users report less impulsivity when they are using methamphetamine compared to when abstaining from drug use, but this hypothesis has not been directly tested. In this study, self-reports of impulsivity were obtained from 32 methamphetamine-dependent (DSM-IV) research participants and 41 healthy control subjects, using the Barratt Impulsiveness Scale-11. The methamphetamine users were assessed during an active period of methamphetamine use, as determined through urinalysis, and again after approximately 1 week of confirmed abstinence. Control subjects likewise completed two assessments. A subset of participants also completed serial assessments of the Beck Depression Inventory (Methamphetamine Group, N = 17, Control Group, N = 38) and the Methamphetamine Withdrawal Questionnaire (Methamphetamine Group, N = 12). There was a significant interaction of group with time on impulsivity (p = 0.044), reflecting a significant increase from the first to the second assessment in the methamphetamine users (p = 0.013), but no change among healthy control subjects. In contrast, depressive and withdrawal symptoms significantly decreased between the first and second assessments in the methamphetamine users (ps ≤0.01). Change in impulsivity in methamphetamine users was not significantly correlated with change in withdrawal or depression (ps >0.05). These findings suggest that methamphetamine users report more impulsivity when abstaining from drug use, an effect that is not significantly related to methamphetamine withdrawal. Attenuation of impulsivity may reinforce continued methamphetamine use in these individuals.

2012-03-01

A peer-driven intervention (PDI) for injecting drug users (IDUs) was implemented in five Ukrainian city-sites to test-pilot its effectiveness in rejuvenating harm reduction (HR) projects that had become moribund. A PDI relies on drug users in a unique way to educate their peers in the community and recruit them for HIV prevention services. The goal of the PDI was to recruit in six month 500 IDUs who had never been respondents before to each of the five HR projects, especially stimulant- and women-injectors, and IDUs<25 years of age. We standardized the PDI's structure and operations across all five sites. All five PDIs were started in May 2007 using a carefully selected handful of "seed" IDU-recruiters who were trained to educate three peers who had never received HR services. We also accessed the database of all five projects and analysed the new respondents they recruited six-months prior to the start-up of the PDIs with the new recruits generated by the PDIs. Whilst the HR projects in the five city-sites recruited 72 new respondents on average during the six months prior to the PDIs' start-up, the PDIs recruited 455 new respondents on average in each city during their six months of operation, indicating that the PDI was 6.3 times more powerful as a recruitment mechanism. Compared to traditional outreach the PDIs resulted in significant increases in the recruitment of women- and young-injectors, and IDUs who injected a more diverse variety of drugs. The PDI can have a rejuvenating effect when added to HR projects that had become stagnate over time, resulting in an increase in the number and diversity of new IDU-respondents.

Altered subjective reward valuation among drug-deprived heavy marijuana users: Aversion to uncertainty

PubMed Central

Hefner, Kathryn R.; Starr, Mark. J.; Curtin, John. J.

2015-01-01

Marijuana is the most commonly used illicit drug in the United States and its use is rising. Nonetheless, scientific efforts to clarify the risk for addiction and other harm associated with marijuana use have been lacking. Maladaptive decision-making is a cardinal feature of addiction that is likely to emerge in heavy users. In particular, distorted subjective reward valuation related to homeostatic or allostatic processes has been implicated for many drugs of abuse. Selective changes in responses to uncertainty have been observed in response to intoxication and deprivation from various drugs of abuse. To assess for these potential neuroadaptive changes in reward valuation associated with marijuana deprivation, we examined the subjective value of uncertain and certain rewards among deprived and non-deprived heavy marijuana users in a behavioral economics decision-making task. Deprived users displayed reduced valuation of uncertain rewards, particularly when these rewards were more objectively valuable. This uncertainty aversion increased with increasing quantity of marijuana use. These results suggest comparable decision-making vulnerability from marijuana use as other drugs of abuse, and highlights targets for intervention. PMID:26595464

To test the validity of drug users self-reports of diseases associated with drug use, in this case hepatitis A, B, and C. Injecting drug users (n = 653) were recruited and asked whether they had been diagnosed previously with hepatitis A, B, and/or C. These self-report data were compared to total hepatitis A antibody, hepatitis B core antibody, and hepatitis C antibody seromarkers as a means of determining the validity of the self-reported information. Anchorage, Alaska. Criteria for inclusion included being at least 18-years old; testing positive on urinalysis for cocaine metabolites, amphetamine, or morphine; having visible signs of injection (track marks). Serological testing for hepatitis A, B, and C. Findings indicate high specificity, low sensitivity, and low kappa coefficients for all three self-report measures. Subgroup analyses revealed significant differences in sensitivity associated with previous substance abuse treatment experience for hepatitis B self-report and with gender for hepatitis C self-report. Given the low sensitivity, the validity of drug users, self-reported information on hepatitis should be considered with caution.

Medical Marijuana Users are More Likely to Use Prescription Drugs Medically and Nonmedically.

PubMed

Caputi, Theodore L; Humphreys, Keith

2018-04-17

Previous studies have found a negative population-level correlation between medical marijuana availability in US states, and trends in medical and nonmedical prescription drug use. These studies have been interpreted as evidence that use of medical marijuana reduces medical and nonmedical prescription drug use. This study evaluates whether medical marijuana use is a risk or protective factor for medical and nonmedical prescription drug use. Simulations based upon logistic regression analyses of data from the 2015 National Survey on Drug Use and Health were used to compute associations between medical marijuana use, and medical and nonmedical prescription drug use. Adjusted risk ratios (RRs) were computed with controls added for age, sex, race, health status, family income, and living in a state with legalized medical marijuana. Medical marijuana users were significantly more likely (RR 1.62, 95% confidence interval [CI] 1.50-1.74) to report medical use of prescription drugs in the past 12 months. Individuals who used medical marijuana were also significantly more likely to report nonmedical use in the past 12 months of any prescription drug (RR 2.12, 95% CI 1.67-2.62), with elevated risks for pain relievers (RR 1.95, 95% CI 1.41-2.62), stimulants (RR 1.86, 95% CI 1.09-3.02), and tranquilizers (RR 2.18, 95% CI 1.45-3.16). Our findings disconfirm the hypothesis that a population-level negative correlation between medical marijuana use and prescription drug harms occurs because medical marijuana users are less likely to use prescription drugs, either medically or nonmedically. Medical marijuana users should be a target population in efforts to combat nonmedical prescription drug use.

All the session were recorded on video-tape and cassette to facilitate its typewriting. The general opinion was that users did not like to take drugs, nevertheless, it was a tool to solve easily and fast a health problem. At the same time, it was a cheap resource comparing to others as massage, health resort, diets... Drugs are seen as interchange currency in the medical bureau. There were critical opinions against abusive consumption of drugs. There is a lack of information concerning the utility and actions of drugs. The speech of user groups shows opposing points of view related to health professional opinions concerning drugs request from users and the role of drugs in the relationship doctor-patient.

Sexual health risk among dance drug users: cross-sectional comparisons with nationally representative data.

To describe the sexual behaviour and related risk of a sample of dance drug users and compare this with data from the UK National Survey of Sexual Attitudes and Lifestyles 2000 survey. Cross-sectional purposive sampling using both self-completion postal and web-based questionnaires. This sample of dance drug users are more sexually active and have more concurrent partners than the general population. Rates of anal or vaginal sex within the last year without condom use are high and of concern (men 80 per cent; women 90 per cent). These dance drug users appear also to have higher lifetime prevalence of sexually transmitted infections than the general population and are also more likely to have ever attended a sexual health clinic. Clubbing and dance drug use, as part of a socially active lifestyle, is associated with elevated and pronounced sexual health risk. Future epidemiological studies of sexual health risk should incorporate investigation of both clubbing and recreational drug use in order to confirm the representativeness of these observations. Clubbers should be considered a target for dedicated sexual health promotion interventions, which may also be combined with interventions targeting drug and alcohol use.

Compared to the general population, drug users are at increased risk of both poor mental health and HIV infection. The aim of this study was to determine the prevalence and correlates of high psychological distress among drug users in Cambodia. In April 2014, a two-stage cluster sampling method was used to randomly select 169 drug users from hotspots in Phnom Penh. Psychological distress was measured using General Health Questionnaire (GHQ-12). Bivariate and multivariable analyses were conducted to identify factors associated with levels of psychological distress among this population. Our study found high prevalence of attempted suicide (15.3%), drug related arrests (46.2%), and incarceration (31.4%). Of the 169 participants, 42.0% were found to have high levels of psychological distress, indicating poor mental health. After adjustment, high levels of psychological distress were independently associated with suicidal ideation (p<0.001), higher frequency of drug use (p=0.02), sharing of needles or syringes (p=0.005), and having been sent to a rehabilitation centre (p=0.02). In addition, participants who perceived their overall health as being poor or very poor were more likely to have high levels of psychological distress (p=0.002). Integration of mental health within HIV and needle and syringe exchange programmes is required to address psychological distress among drug users in Cambodia. Health system interventions, such as screening, referral, and training of health providers, need to be strengthened. In addition, interventions addressing social determinants of mental health and mitigation of frequent arrests and improving conditions in rehabilitation centres are required.

Alfaro Murillo, E

1990-01-01

This article provides a review of drug use surveys conducted by Costa Rica's Institute on Alcoholism and Drug Dependence during the years 1983-1987. These studies dealt with a wide range of subjects--residents of marginal neighborhoods, juvenile male and adult female detainees, and high school students--as well as with the general population. Overall, the studies indicated that the most commonly used illicit drug was marijuana, that the bulk of the drug users (excluding alcohol and tobacco users) were young males, that relevant levels of cocaine use were starting to occur, and that the country's general drug abuse picture poses a problem in need of immediate attention.

The war in Afghanistan in 2001 may have had direct or indirect effects on drug users' behaviors in nearby Pakistan. We studied drug use patterns and correlates of needle sharing among injection drug users (IDUs) in Lahore, Pakistan, before and after the beginning of the Afghanistan war. Between August and October 2001, 244 drug users registering for needle exchange and other services underwent an interviewer-administered survey on sociodemographics, drug use and HIV/AIDS awareness. chi(2)-tests were used to compare drug use behaviors among subjects interviewed before and after October 6th, 2001, coinciding with the start of the Afghanistan war. Correlates of needle sharing among IDUs were identified using logistic regression. Comparing IDUs interviewed before and after October 6th, 2001, levels of needle sharing were significantly higher after the war (56% versus 76%, respectively; P=0.02). Factors independently associated with needle sharing included registering after the war began (adjusted odds ratio, AOR=3.76 (95% CI: 1.23-11.48)), being married (AOR=0.36), being homeless (AOR=3.91), having been arrested (AOR=6.00), and re-using syringes (AOR=6.19). Expansion of needle exchange, drug treatment and supportive services is urgently needed to avoid an explosive HIV epidemic in Pakistan.

Online drug user-led harm reduction in Hungary: a review of “Daath”

PubMed Central

2013-01-01

Harm reduction has been increasingly finding its way into public drug policies and healthcare practices worldwide, with successful intervention measures justifiably focussing on the highest-risk groups, such as injecting drug users. However, there are also other types of drug users in need for harm reduction, even though they pose less, low, or no public health risk. Occasionally, drug users may autonomously organise themselves into groups to provide advocacy, harm reduction, and peer-help services, sometimes online. The http://www.daath.hu website has been operated since 2001 by the “Hungarian Psychedelic Community”, an unorganised drug user group with a special interest in hallucinogenic and related substances. As of today, the website serves about 1200 visitors daily, and the online community comprises of more than 8000 registered members. The Daath community is driven by a strong commitment to the policy of harm reduction in the form of various peer-help activities that aim to expand harm reduction without promoting drug use. Our review comprehensively summarises Daath’s user-led harm reduction services and activities from the last ten years, firstly outlining the history and growth phases of Daath, along with its self-set guidelines and policies. Online services (such as a discussion board, and an Ecstasy pill database) and offline activities (such as Ecstasy pill field testing, and a documentary film about psychedelics) are described. In order to extend its harm reduction services and activities in the future, Daath has several social, commercial, and legislative challenges to face. Starting with a need to realign its focus, outlooks for the upcoming operation of Daath are pondered. Future trends in harm reduction, such as separating harm-decreasing from benefit-increasing, are also discussed. We aim to share these innovative harm reduction measures and good practices in order to be critically assessed, and – if found useful – adapted and applied

To analyze the serological results and sexual behavior among different types of drug users (DUS) at the HIV sentinel surveillance sites. Sentinel surveillance programs were conducted between April and June annually. DUS were those involved in custodes, living at the communities and those attending the methadone maintenance treatment clinics but with positive urine tests one month before blood sampling collected and questionnaire survey started. 116 279 drug abusers were included in the analysis. The prevalence rates of HIV, Syphilis and HCV among traditional drug (heroin, etc.)users were 5.0%, 4.4% and 49.4%, while the prevalence rates of new narcotic (meth, etc.) users were 0.5%, 4.6%, 15.2%, respectively. The prevalence rates of HIV, syphilis among traditional drug uses were higher than the new narcotic users (P < 0.01). The proportion of sexual behavior in last month and the proportion of sexual behavior with casual and commercial sexual partners were 46.3%, 87.2% and 28.1% among the new narcotic users, respectively, which were higher than those among traditional drug users (40.7% , 82.8% and 22.2%). The proportion of using condom in last sexual contact with casual sexual partner was 33.3% among the new narcotic users which was less than traditional drug users (36.2%). The proportion of condom use in the last commercial sexual contact was 65.1% which was higher than those traditional drug users (62.9%). The proportion of never using condom with casual and commercial sexual partners in the past year was 43.2% and 19.0% among the traditional drug users, which were higher than those among new narcotic users (41.3%, 15.3%). Compared with the traditional drug abusers, the sexual behavior of new narcotic users seemed more active, less engaging in condom use but with higher risk of HIV transmission through sexual contact.

In Indonesia, an ongoing government "war on drugs" has resulted in numerous arrests and anecdotal reports of abuse in detention, but to date there has been little documentation or analysis of this issue. JANGKAR (also known in English as the Indonesian Harm Reduction Network), a nongovernmental organization (NGO) based in Jakarta, surveyed 1106 injecting drug users in 13 cities about their experiences of police abuse. Of those interviewed, 667 or 60% reported physical abuse by police. These findings indicate the importance of continuing efforts to promote police reform and harm reduction in Indonesia.

1986-01-01

Subjects (n = 108) who volunteered to participate in a study in which they expected to smoke marijuana were asked, as part of a screening procedure, to rate the harmfulness of a number of illicit drugs including marijuana. Subjects were separated into three groups according to their reported history of use of marijuana. The three groups were: naive users (at least 1 but no more than 25 incidences of use in a lifetime), light users (1 to 3 incidences of use per week), and heavy users (at least 5 incidences of use per week). Groups did not differ in terms of their perceived harmfulness of any of the drugs. Cluster analyses of the results for each group and for the total group indicated three distinct clusters: the drugs perceived to be the most harmful were heroin, morphine, and LSD; drugs perceived to be less harmful were cocaine, amphetamines, barbiturates, and nicotine; and the drugs perceived to be the least harmful were caffeine and marijuana, with marijuana being judged the least harmful of all the drugs.

The relationship between social network characteristics and exchanging sex for drugs or money among drug users in Baltimore, MD, USA.

2003-11-01

The current study examined social network and drug use factors associated with buying and selling sex among a sample of opiate and cocaine users in Baltimore, Maryland. A sample of 702 drug users who were sexually active were administered a social network and risk behaviour inventory. Compared to 25% of men, only 1.7% of women reported a history of giving money or drugs to get sex during the past 90 days. Conversely, more women (21.2%) than men (4.7%) sold sex for money or drugs. Those who sold sex were more likely to be low frequency crack smokers, were more likely to drink alcohol at least once a day, had a higher average number of crack-only smokers in their network, and had a smaller number of kin in their network. Men who exchanged money or drugs for sex tended to be low frequency crack smokers and reported having more crack-only smokers and injectors and fewer kin in their networks. The results suggest that network composition may be a risk factor for exchanging sex, particularly with respect to crack users, while kin may be a protective factor. These associations may be either a cause or consequence of exchanging sex.

Road traffic crashes associated with nightlife alcohol and recreational drug use are a major health problem for young people. This study explores use of different forms of transport to and from nightlife environments and the relationships between traffic risk behaviors, drunkenness, and drug consumption. 1363 regular nightlife users from nine European cities in 2006 completed a self-administered and anonymous questionnaire. Sampling utilized a variation of respondent-driven sampling. Private car was the most frequent form of transport used when going out, especially by males and older individuals. Drug use was related to crashes and traffic risk behaviors, including having a lift from someone drunk or driving drunk or driving having taken drugs; drunkenness was related to risk behaviors but not to crashes (possibly because drunk people tend to use the private car less). Males showed higher levels of drunkenness and drug consumption, traffic risk behaviors, and traffic crashes. Age is not related to the traffic risk behaviors, but older individuals had less crashes. There are serious health problems related to transport and recreational nightlife activities. It is necessary to improve later public transport services, complemented by actions that deter the use of private cars. The relationships of both drunkenness and cannabis/cocaine use with traffic risk behaviors should be addressed and programs implemented to change risk perceptions on the effects of illegal drugs on driving.

Opiates drug users are at much higher risk of developing tuberculosis (TB) infection than general population. We conducted this study to determine the susceptibility for pulmonary and latent TB infection in opiates drug users. In this cross-sectional study, all opiates drug users referred to drop-in centers, methadone maintenance clinics, and harm-reduction facilities affiliated with Shiraz University of Medical Sciences in southern Iran were screened for pulmonary and latent TB infection. The participation rate of opiate drug users was 87.66% (263 of 300). Mean age was 37.37 ± 8.33 (range, 20-65) years. Two hundred twenty-six (85.93%) were male and 197 (74.90%) were injection drug users (IDUs). One hundred sixty-three (61.97%) had TB-related symptoms. Culture for TB was positive in 3 patients (1.14%) (2 non-IDUs and 1 IDU). Two patients (0.76%) showed acid-fast bacilli in the direct sputum smear. Eighty-five of 244 patients (34.83%) had a 5- to 10-mm induration in the skin TB test. Twenty-nine of 223 patients (13%) had abnormal findings from chest x-ray films. The prevalence of smear-positive pulmonary TB in opiate drug users is more than 100 times in the general population in Iran. Therefore, active and appropriate screening to detect pulmonary TB infection should be integrated into routine activities at all harm-reduction facilities for drug users, irrespective of their route of drug use or human immunodeficiency virus status, in this country.

Cognitive function in ecstasy naive abstinent drug dependants and MDMA users.

'Hidden' symptoms, or subtle cognitive deficits and long-term changes in mood, have been linked to the recreational use of 3, 4-methylenedioxymethamphetamine/MDMA, and are notionally present in non-heavy polydrug users. This study assessed the cognitive functioning and mood profiles of clinically diagnosed drug dependents who had never consumed MDMA, recreational drug users that had previously consumed MDMA, with both groups having not consumed illicit drugs for 6-months, and a control group with limited illicit drug use and no MDMA usage in their past. Cognitive functioning was assessed using the Cognitive Drug Research computerised cognitive assessment system and participants completed the Profile of Mood States and Beck Depression Inventory to assess their current mood and depression. Participants in the clinically diagnosed drug dependent group scored significantly worse on the 'Quality of Working Memory' cognitive factor score than both the MDMA and control group (F (2, 33) = 5.75, p = 0.007). The control and clinical groups also differed on depression scores (U [16] = 13.00, p = 0.016) and Tension/Anxiety scores (U [16] = 16.00, p = 0.034), with the clinical group scoring significantly higher in both cases. The MDMA group did not differ from the control group on the measures of cognition or mood. These results suggest that despite a 6-month prolonged abstinence the cognitive deficits ostensibly caused by 'heavy' usage or the dependence on or abuse of illicit drugs are not reversed by abstinence.

DNA sequencing of a pol gene fragment from drug-naive injecting drug users samples obtained at two time points of the Brazilian AIDS epidemic (Pre-HAART era: 1994 to early 1997, n = 27; post-HAART era: 1999-2001, n = 38) was undertaken to assess HIV-1 antiretroviral drug resistance mutations and subtyping profiles. Genotypic analysis revealed the presence of PR primary L90M, D30N, M46I, and V82A mutations in 7.9% of the post-HAART group, and a high frequency of secondary mutations (84.2%). Nucleoside RT-associated mutations were observed in 13.2%. In the pre-HAART group, a higher frequency of RT mutations was observed (22.2%) and no PR primary mutations were found, in agreement with the introduction of protease inhibitors (PIs) in therapy during the same period. The identification of 7.9% of drug-naive injecting drug users already bearing RT/PR primary resistance mutations in the post-HAART era group constitutes a major concern in terms of dissemination of drug resistant viruses. The resistance mutations profile of the individuals may reflect the context of antiretroviral treatment in Brazil at the sample collection periods (1994-1997 and 1999-2001). In spite of the differences observed in the drug resistance profiles, similar frequencies of subtype B (63.0 vs. 73.7%), F (22.2 vs. 10.5%), and recombinant B/F (14.8 vs. 15.8%) viruses were found, respectively, in the pre- and post-HAART groups.

A choice-based screening method for compulsive drug users in rats.

2013-07-01

We describe a protocol for screening compulsive drug users among cocaine self-administering rats, the most frequently used animal model in addiction research. Rats are first trained on several alternating days to self-administer either cocaine (i.v.) or saccharin-sweetened water (by mouth)--a potent, albeit nonessential, nondrug reward. Then rats are allowed to choose between the two rewards over several days until the preference stabilizes. Most rats choose to stop using cocaine and pursue the alternative reward. Only a minority of Wistar strain rats (generally 15%) persist in taking the drug, regardless of the severity of past cocaine use and even when made hungry and offered the possibility to relieve their physiological need. Persistence of cocaine use in the face of a high-stakes choice is a core defining feature of compulsion. This choice-based screening method for compulsive drug users is easy to implement, has several important applications, and compares well with other methods in the field. 2013 by John Wiley & Sons, Inc.

Postmarketing studies of drugs forms an essential part of safety surveillance. In particular, this concerns new drugs as safety information of these by large rests on randomized clinical studies conducted on a limited number of subjects before licensing. Pharmacists in community pharmacies are in a unique position for detection of user experienced adverse drug reactions (ADRs) in relation to drug dispensing. The study reports from a research initiative exploring prompt and proactive ADR detection of liraglutide and reporting facilitated by pharmacy students undertaking internship in a community pharmacy in Denmark. Nineteen pharmacy students undertaking regular 6 months' internship--eighth semester--in a Danish community pharmacy participated in the data collection. Before the data collection, students attended an interactive training seminar addressing ADRs in general, organ symptoms, diagnostic classification, and pharmacovigilance systems. Pharmacy students approached recurrent drug users purchasing liraglutide. Participating users were asked about experienced ADRs linked to liraglutide use. Reported ADRs were collected and analyzed. Sixty-two liraglutide users participated in the study, of whom, 38 reported 84 ADRs possibly linked to liraglutide usage. Nausea was by far the most reported ADR followed by decreased appetite, diarrhea, fatigue, and abdominal pain (upper). The reported ADRs are in accordance with previously reported ADRs. The study has demonstrated the feasibility of community pharmacy driven pharmacovigilance. The study supports the thesis that community pharmacists in the future may play a proactive and prominent role in patient-centered pharmacovigilance.

Prior studies estimate HIV prevalence of 4% among injection drug users (IDUs), compared with 0.8% in the general population of Tijuana, Mexico. However, data on HIV prevalence and correlates among non-injecting drug users (NIDUs) are sparse. Individuals were recruited through street outreach for HIV testing and behavioural risk assessment interviews to estimate HIV prevalence and identify associated sexual risk behaviours among NIDUs in Tijuana. Descriptive statistics were used to characterise 'low-risk' NIDUs (drug users who were not commercial sex workers or men who have sex with men). Results showed that HIV prevalence was 3.7% among low-risk NIDUs. During the prior six months, 52% of NIDUs reported having >1 casual partner; 35% reported always using condoms with a casual partner; and 13% and 15%, respectively, reported giving or receiving something in exchange for sex. Women were significantly more likely than men to have unprotected sex with an IDU (p<0.01). The finding that HIV prevalence among NIDUs was similar to that of IDUs suggests that HIV transmission has occurred outside of traditional core groups in Tijuana. Broad interventions including HIV testing, condom promotion and sexual risk reduction should be offered to all drug users in Tijuana.

Depression is more common among drug users (15-63 %) than the general population (5-16 %). Lack of social support network members may be associated with low mental health service (MHS) use rates observed among drug users. We investigated the relationship between social network members' roles and MHS use among frequent drug users using Social Ties Associated with Risk of Transition into Injection Drug Use data (NYC 2006-2009). Surveys assessed depression, MHS use, demographics, drug use and treatment, and social network members' roles. Participants reporting lifetime depressive episode with start/end dates and information on social/risk network members were included (n = 152). Adjusting for emotional support and HIV status, having one or more informational support network members remained associated with MHS use at last depressive episode (adjusted odds ratio (AOR) 3.37, 95 % confidence interval (CI) 1.38-8.19), as did history of drug treatment (AOR 2.75, 95 % CI 1.02-7.41) and no legal income (AOR 0.23, 95 % CI 0.08-0.64). These data suggest that informational support is associated with MHS utilization among depressed drug users.

Managing leg ulceration in intravenous drug users.

PubMed

Geraghty, Jemell

2015-09-01

Chronic venous leg ulceration is a long-term condition commonly associated with lower-limb injecting and chronic venous hypertension caused by collapsed veins, incompetent valves, deep vein thrombosis and reflux. It is not usually a medical emergency, but intravenous (IV) drug users with leg ulcers can attend emergency departments (EDs) with a different primary complaint such as pain or because they cannot access local primary care or voluntary services. Leg ulceration might then be identified during history taking, so it is important that ED nurses know how to assess and manage these wounds. This article explains how to assess and manage chronic venous leg ulcers in patients with a history of IV drug use, and highlights the importance of referral to specialist services when required, and to local primary care or voluntary services, before discharge to prevent admission and re-attendance.

Patterns of drug use from adolescence to young adulthood: II. Sequences of progression.

PubMed Central

Yamaguchi, K; Kandel, D B

1984-01-01

Major pathways of progression among legal, illegal, and medically prescribed psychoactive drugs from adolescence to young adulthood are described. The data are based on a follow-up cohort of former adolescents representative of high school students in grades 10 and 11 in New York State who were reinterviewed nine years later at ages 24-25. Various models of progression are tested for their goodness of fit. The patterns formerly observed in adolescence involving progression from one class of legal drug (either alcohol or cigarettes) to marijuana to the use of other illicit drugs appear in the transitional period into young adult, with an additional stage, that of prescribed psychoactive drugs. Some differences appear between men and women, with cigarettes more important for women than for men in the total progression. PMID:6742252

Brazilian drugs legislation has evolved from a prohibitionist system to a less repressive one in terms of drug users. The objective of this study was to identify the perception of relatives and acquaintances of drug users living in Ribeirão Preto, São Paulo, Brazil, about the country's laws and policies on drugs. Data collection was performed using a structured questionnaire. The sample consisted of 100 drug users' relatives or acquaintances, selected at a public health service. Respondents' relationships with the drug user were as follows: 31% friend, 23% sibling, 15% child and 7% spouse. Most users (78%) were men, with an average age of 26 years. Results confirm that national laws and policies have a direct effect on individuals' attitude and behaviors. There is a lack of trust in the police and a general perception that, despite recent chances that favor user rehabilitation, the laws on drugs do not respect users' human rights.

The outcomes of counseling and testing programs related to human immunodeficiency virus (HIV) infection and risk of infection among injection drug users (IDUs) are not well known or understood. A counseling and testing outcome of potential public health importance is attaining admission to drug abuse treatment by those IDUs who are either infected or who are at high risk of becoming infected. The authors investigated factors related to admission to drug abuse treatment among 519 IDUs who received HIV counseling and testing from September 1987 through December 1990 at a men's prison and at community-based testing sites in Worcester, MA. By June 1991, 123 of the 519 IDUs (24 percent) had been admitted to treatment. Variables associated with their admission included a long history of drug injection, frequent recent drug injection, cleaning injection equipment using bleach, prior drug treatment, and a positive HIV test result. Logistic regression analyses, controlling for effects of recruitment site, year, sex, and area of residence, generally confirmed the associations. IDUs in the study population who were HIV-infected sought treatment or were admitted to treatment more frequently than those who were not infected. The results indicate that access to drug abuse treatment should be facilitated for high-risk IDUs and for those who have begun to inject drugs recently.

Objective: The present study aimed at comparing the prevalence of major psychiatric disorders including major depressive disorder, bipolar disorder, schizophrenia, and generalized anxiety disorder between performance-enhancing drug users and nonuser bodybuilders. Moreover, the prevalence of major psychiatric disorders in bodybuilders was also reported. Method: In this study, 453 athletes were recruited from Bushehr bodybuilding gyms from February to May 2015. A structured questionnaire was used to collect the participants' information, including demographic characteristics, sports' status and performance-enhancing drug use. According to the condition of performance-enhancing drug use, the participants were divided into current users, non-current users, and nonusers. The psychiatric status of the participants was evaluated using DSM-IV diagnostic criteria for major depressive disorder, bipolar disorder, generalized anxiety disorder, and schizophrenia. We also asked about the acute psychotic disturbances after using performance-enhancing drugs, alcohol use, and history of aggressive behavior in bodybuilders. Data were analyzed using one-way analysis of variance and chi-square tests. Results: Prevalence of major depressive disorder, bipolar disorder, schizophrenia, generalized anxiety disorder, and the overall prevalence of psychiatric disorders in the bodybuilders was 19.7%, 3.8%, 1.5%, 16.6%, and 26.7%, respectively. After using performance-enhancing drugs, 33% of the bodybuilders had experienced acute psychological disturbances. There were no significant differences between current, non-current, and nonuser bodybuilding athletes in the measured psychiatric disorders. Conclusion: Prevalence of psychiatric disorders was not significantly different in performance-enhancing drug users and nonusers. Thus, it can be concluded that performance-enhancing drugs do not increase the risk of psychiatric disorders in bodybuilders.

Objectives Despite extensive research into the determinants of electronic nicotine delivery system (ENDS) uptake, few studies have examined the psychosocial benefits ENDS users seek and experience. Using a consumer ritual framework, we explored how ENDS users recreated or replaced smoking practices, and considered implications for smoking cessation. Design In-depth interviews; data analysed using thematic analysis. Setting Dunedin, New Zealand. Participants 16 young adult ENDS users (age M=21.4, SD=1.9; 44% female). Results Participants reported using different ENDS to achieve varying outcomes. Some used ‘cigalikes’ to recreate a physically and visually similar experience to smoking; they privileged device appearance over nicotine delivery. In contrast, others used personally crafted mods to develop new rituals that differentiated them from smokers and showcased their technical expertise. Irrespective of the device they used, several former smokers and dual users of cigarettes and ENDS experienced strong nostalgia for smoking attributes, particularly the elemental appeal of fire and the finiteness of a cigarette. Non-smoking participants used ENDS to maintain social connections with their peers. Conclusions Participants used ENDS to construct rituals that recreated or replaced smoking attributes, and that varied in the emphasis given to device appearance, nicotine delivery, and social performance. Identifying how ENDS users create new rituals and the components they privilege within these could help promote full transition from smoking to ENDS and identify those at greatest risk of dual use or relapse to cigarette smoking.

Drug policing assemblages: Repressive drug policies and the zonal banning of drug users in Denmark's club land.

Søgaard, Thomas F; Houborg, Esben; Pedersen, Michael M

2017-03-01

Zonal banning of disorderly and intoxicated young people has moved to centre stage in debates about nightlife governance. Whereas existing research has primarily focused on the use of zonal banning orders to address problems of alcohol-related harm and disorder, this article highlights how zonal banning is also used to target drug-using clubbers in Denmark. Based on ethnographic observations and interviews with nightlife control agents in two Danish cities, the article aims to provide new insights into how the enforcement of national drug policies on drug-using clubbers, is shaped by plural nightlife policing complexes. The paper demonstrates how the policing of drug-using clubbers is a growing priority for both police and private security agents. The article also demonstrates how the enforcement of zonal bans on drug-using clubbers involves complex collaborative relations between police, venue owners and private security agents. The paper argues that a third-party policing perspective combined with assemblage theory is useful for highlighting how the enforcement of national drug policies and nightlife banning systems is shaped by their embeddedness in local 'drug policing assemblages' characterized by inter-agency relation-building, the creative combination of public and private (legal) resources and internal power struggles. It also provides evidence of how drug policing assemblages give rise to many different, and often surprising, forms of jurisdiction involving divergent performances of spaces-, objects- and authorities of governance.

Injecting drug users (IDUs) are at risk of parenterally transmitted diseases such as hepatitis B virus (HBV) hepatitis C virus (HCV) and human immunodeficiency virus (HIV) infections. The present study was undertaken to find out the prevalence of HIV infection, HBV infection and HCV infection among IDUs of a deaddiction centre. Serum samples from 250, injecting drug users (IDUs) from a de-addiction centre were screened for HBsAg using immunochromatography, anti HCV antibody by 3rd generation ELISA test and anti HIV antibody by ELISA test and immunochromatographic rapid test during the period August to October 2002. One hundred and forty-nine (59.6%) IDUs were positive for HIV antibody, 226 (90.4%) were positive for anti HCV antibody and 27 (10.8%) were positive for HBsAg. There was co-infection of HIV, HBV and HCV in 15 (6%) of the IDUs. The Co-infection of HBV and HCV were found in 12 cases (4.8%) and Co-infection of HIV and HCV was found in 131 cases (52.4%). The IDUs were in sexually active age group with a risk of infection to their sexual partner. There is high prevalence of HCV and HIV infection and co-infection of both viruses among IDUs. Comprehensive public health interventions targeting this population and their sexual partners must be encouraged. Increase coverage of needle, syringe exchange programme (NSEP) to young and new IDUs is required before they are exposed to blood borne viruses.

Extensively drug-resistant (XDR) tuberculosis is becoming increasingly prevalent worldwide, but little is known about XDR tuberculosis in young children. In this Grand Round we describe a 2-year-old child from the USA who developed pneumonia after a 3 month visit to India. Symptoms resolved with empirical first-line tuberculosis treatment; however, a XDR strain of Mycobacterium tuberculosis grew in culture. In the absence of clinical or microbiological markers, low-radiation exposure pulmonary CT imaging was used to monitor treatment response, and guide an individualised drug regimen. Management was complicated by delays in diagnosis, uncertainties about drug selection, and a scarcity of child-friendly formulations. Treatment has been successful so far, and the child is in remission. This report of XDR tuberculosis in a young child in the USA highlights the risks of acquiring drug-resistant tuberculosis overseas, and the unique challenges in management of tuberculosis in this susceptible population.

Background Chronic noncommunicable diseases (NCDs) such as asthma, diabetes, cancer, and persistent musculoskeletal pain impose an escalating and unsustainable burden on young people, their families, and society. Exploring how mobile health (mHealth) technologies can support management for young people with NCDs is imperative. Objective The aim of this study was to identify, appraise, and synthesize available qualitative evidence on users’ experiences of mHealth technologies for NCD management in young people. We explored the perspectives of both end users (young people) and implementers (health policy makers, clinicians, and researchers). Methods A systematic review and meta-synthesis of qualitative studies. Eligibility criteria included full reports published in peer-reviewed journals from January 2007 to December 2016, searched across databases including EMBASE, MEDLINE (PubMed), Scopus, and PsycINFO. All qualitative studies that evaluated the use of mHealth technologies to support young people (in the age range of 15-24 years) in managing their chronic NCDs were considered. Two independent reviewers identified eligible reports and conducted critical appraisal (based on the Joanna Briggs Institute Qualitative Assessment and Review Instrument: JBI-QARI). Three reviewers independently, then collaboratively, synthesized and interpreted data through an inductive and iterative process to derive emergent themes across the included data. External validity checking was undertaken by an expert clinical researcher and for relevant content, a health policy expert. Themes were subsequently subjected to a meta-synthesis, with findings compared and contrasted between user groups and policy and practice recommendations derived. Results Twelve studies met our inclusion criteria. Among studies of end users (N=7), mHealth technologies supported the management of young people with diabetes, cancer, and asthma. Implementer studies (N=5) covered the management of cognitive and

Background Rates of young adult cannabis use are rising, perceived harm is at its historical nadir, and most users do not want to quit. Most studies evaluating effects of cannabis use in young adults are cross-sectional, limiting causal inference. A method to reliably induce abstinence periods in cannabis users would allow assessment of the effects of abstinence and resumption of use on a variety of outcomes in a within subjects, repeated measure design. Methods We examined the efficacy and feasibility of a voucher-based contingency management procedure for incentivizing one month of continuous cannabis abstinence among young adults who reported at least weekly cannabis use, volunteered to participate in a laboratory study, and did not express desire to discontinue cannabis use long-term. Continuous cannabis abstinence was reinforced with an escalating incentive schedule, and self-report of abstinence was confirmed by frequent quantitative assays of urine cannabis metabolite (THCCOOH) concentration. New cannabis use during the abstinence period was determined using an established algorithm of change in creatinine-adjusted cannabis metabolite concentration between study visits. Results Thirty-eight young adults, aged 18–25, enrolled and 34 (89.5%) attained biochemically confirmed 30-day abstinence. Among those who attained abstinence, 93.9% resumed regular use within two-weeks of incentive discontinuation. Conclusion Findings support the feasibility and efficacy of contingency management to elicit short-term, continuous cannabis abstinence among young adult, non-treatment-seeking, regular cannabis users. Further work should test the effectiveness of this CM procedure for cannabis abstinence periods longer than one month, which may be required to evaluate some effects of abstinence. PMID:27590742

Although prescription drugs are readily available on the Internet, little is known about the prevalence of Internet use for the purchase of medications without a legitimate prescription, and the characteristics of those that obtain non-prescribed drugs through online sources. The scientific literature on this topic is limited to anecdotal reports or studies plagued by small sample sizes. Within this context, the focus of this paper is an examination of five national data sets from the U.S. with the purpose of estimating: (1) how common obtaining prescription medications from the Internet actually is, (2) who are the typical populations of "end users" of these non-prescribed medications, and (3) which drugs are being purchased without a prescription. Three of the data sets are drawn from the RADARS (Researched Abuse Diversion and Addiction-Related Surveillance) System, a comprehensive series of studies designed to collect timely and geographically specific data on the abuse and diversion of a number of prescription stimulants and opioid analgesics. The remaining data sets include the National Survey on Drug Use and Health (NSDUH) and the Monitoring the Future (MTF) survey. Our analysis yielded uniformly low rates of prescription drug acquisition from online sources across all five data systems we examined. The consistency of this finding across very diverse populations suggests that the Internet is a relatively minor source for illicit purchases of prescription medications by the individual end-users of these drugs.

Among drug users with HIV and Hepatitis C Virus (HCV) infections, heavy drinking can pose significant risks to health. Yet many drug users with HIV and HCV drink heavily. Clarifying the relationship of drug-using patients' understanding of their illnesses to their drinking behavior could facilitate more effective intervention with these high-risk groups. Among samples of drug users infected with HIV (n=476; 70% male) and HCV (n=1145; 81% male) recruited from drug treatment clinics, we investigated whether patients' perceptions of the risk for severe outcomes related to HIV and HCV were associated with their personal drinking behavior, using generalized logit models. Interactions with co-infection status were also explored. HIV-infected drug users who believed that HIV held highest risk for serious outcomes were the most likely to be risky drinkers, when compared with those with less severe perceptions, X(2)(6)=14.19, p<0.05. In contrast, HCV-infected drug users who believed that HCV held moderate risk for serious outcomes were the most likely to be risky drinkers, X(2)(6)=12.98, p<0.05. In this sample of drug users, risky drinking was most common among those with HIV who believed that severe outcomes were inevitable, suggesting that conveying the message that HIV always leads to severe outcomes may be counterproductive in decreasing risky drinking in this group. However, risky drinking was most common among those with HCV who believed that severe outcomes were somewhat likely. Further research is needed to understand the mechanisms of these associations.

Effects of transnational migration on drug use: an ethnographic study of Nepali female heroin users in Hong Kong.

Past studies of female drug users in South Asia tend to focus on their plights, for instance, how they have been driven to drug use and encounter more problems than their male counterparts, such as HIV/AIDS and sexual abuse. Few studies focus on their active role--how they actively make use of resources in the external environment to construct their desired femininity through drug consumption. Furthermore, little is known about the situation of female South Asian drug users who are living overseas. This paper is a study of transnational migration, drug use and gender--how transnational migration influences the drug use of female transnational migrants. An 18-month ethnography has been carried out in a Nepali community in Hong Kong and 13 informants were interviewed. Data were coded and analyzed by using the grounded-theory approach. Themes related to the drug use of the female Nepali heroin users were identified. The findings show that there are three important themes that significantly affect the drug use of female Nepali heroin users, which include (1) their relationships with intimate partners, (2) their means of support, and (3) their legal status in migration. The findings are consistent with the concept of post-structuralism in gender and transnationalism theories. Female Nepali heroin users in Hong Kong are neither active agents nor passive victims; their active/passive role is largely dependent on their reconfigured opportunities and constraints in transnational migration. Thus, transnationalism should be taken as an important perspective to study the situation of female drug users in a globalized context. Copyright © 2014 Elsevier B.V. All rights reserved.

Patterns, determinants and barriers of health and social service utilization among young urban crack users in Brazil

PubMed Central

2013-01-01

Background Crack use is prevalent across the Americas, and specifically among marginalized urban street drug users in Brazil. Crack users commonly feature multiple physical and mental health problems, while low rates of and distinct barriers to help service use have been observed in these populations. This study examined profiles and determinants of social and health service utilization, and unmet service needs, in a two-city sample of young (18–24 years), marginalized crack users in Brazil. Methods N = 160 study participants were recruited by community-based methods from impoverished neighborhoods in the cities of Rio de Janeiro (n = 81) and Salvador (n = 79). A mixed methods protocol was used. Participants’ drug use, health, and social and health service utilization characteristics were assessed by an anonymous interviewer-administered questionnaire completed in a community setting; descriptive statistics on variables of interest were computed. Service needs and barriers were further assessed by way of several focus groups with the study population; narrative data were qualitatively analyzed. The study protocol was approved by institutional ethics review boards; data were collected between November 2010 and June 2011. Results The majority of the sample was male, without stable housing, and used other drugs (e.g., alcohol, marijuana). About half the sample reported physical and mental health problems, yet most had not received medical attention for these problems. Only small minorities had utilized locally available social or health services; utilization appeared to be influenced by sex, race and housing characteristics in both sites. Participants cited limited service resources, lack of needs-specific professional skills, bureaucratic barriers and stigma as obstacles to better service access. However, most respondents stated strong interest and need for general social, health and treatment services designed for the study population, for which various

Abstract Drug users are increasingly recognized as a key population driving human immunodeficiency virus (HIV) spread in sub-Saharan Africa. To determine HIV-1 subtypes circulating in this population group and explore possible geographic differences, we analyzed HIV-1 sequences among drug users from Nairobi, Mombasa, and Kisumu in Kenya. We sequenced gag and env from 55 drug users. Subtype analysis from 220 gag clonal sequences from 54 of 55 participants (median = 4/participant) showed that 44.4% were A, 16.7% were C, 3.7% were D, and 35.2% were intersubtype recombinants. Of 156 env clonal sequences from 48 of 55 subjects (median = 3/participant), 45.8% were subtype A, 14.6% were C, 6.3% were D, and 33.3% were recombinants. Comparative analysis of both genes showed that 30 (63.8%) participants had concordant subtypes, while 17 (36.2%) were discordant. We identified one genetically linked transmission pair and two cases of dual infection. These data are indicative of extensive HIV-1 intersubtype recombination in Kenya and suggest decline in subtype D prevalence. PMID:28068781

This study which assesses the association between the attachment styles of drug-user husbands (n = 56) and their wives (n = 56) and their perceptions of family dynamics was conducted in 1998. The population study included heroin (52.9%) and multidrug detoxified outpatients. All subjects completed the Adult Attachment Style Scale and the FACES III. Results indicated that the perceptions of family adaptability and cohesion among the drug-user husbands and their wives did not differ from the Israeli norm. Most of the drug users (60.7%) were characterized by the avoidant attachment style, followed by the secure style (26.8%), and the anxious/ambivalent style (12.5%). Half the wives (53.6%) were characterized by the secure style, followed by the avoidant style (42.9%) and the anxious/ambivalent style (3.6%). A secure style in husband and wife was associated with higher levels of family cohesion and adaptability, and the anxious/ambivalent style with a lower perception of family cohesion and adaptability. These findings have important implications for rehabilitation prospects and for planning intervention programs.

Drug users are increasingly recognized as a key population driving human immunodeficiency virus (HIV) spread in sub-Saharan Africa. To determine HIV-1 subtypes circulating in this population group and explore possible geographic differences, we analyzed HIV-1 sequences among drug users from Nairobi, Mombasa, and Kisumu in Kenya. We sequenced gag and env from 55 drug users. Subtype analysis from 220 gag clonal sequences from 54 of 55 participants (median = 4/participant) showed that 44.4% were A, 16.7% were C, 3.7% were D, and 35.2% were intersubtype recombinants. Of 156 env clonal sequences from 48 of 55 subjects (median = 3/participant), 45.8% were subtype A, 14.6% were C, 6.3% were D, and 33.3% were recombinants. Comparative analysis of both genes showed that 30 (63.8%) participants had concordant subtypes, while 17 (36.2%) were discordant. We identified one genetically linked transmission pair and two cases of dual infection. These data are indicative of extensive HIV-1 intersubtype recombination in Kenya and suggest decline in subtype D prevalence.

Objective The use of heroin, cocaine, and other drugs is well researched in New York City, but prescription opioids (POs) have been overlooked. This study documents patterns of PO use, misuse, and diversion among street drug users, and begins to indicate how drug culture practices interact with the legitimate therapeutic goals of PO prescriptions (e.g. pain management). Methods Staff completed interviews inquiring about the reasons for use of POs and illicit drugs with 586 street drug users. Ethnographers wrote extensive field notes about subjects’ complex patterns of PO use. Results Methadone was used (71.9%) and sold (64.7%) at a higher level than OxyContin, Vicodin, and Percocet, used by between 34% and 38% of the users and sold by between 28% and 41% of the sellers. Recent PO use is associated with the recency of using heroin and cocaine (p<.001). Half of the heroin/cocaine sellers sold POs, and one quarter of the PO sellers only sold POs. Subjects were classified into four groups by whether they diverted POs or used POs to relieve pain or withdrawal rather than for euphoria. This classification was associated with frequency of PO use, whether POs were obtained from doctors/pharmacies or from drug dealers and family members, and those mostly likely to use POs for pain and withdrawal. Conclusions POs are an important component of street drug users’ drug-taking regimes, especially those who are Physically III Chemical Abusers (PICA). Future research is needed to model PO use, misuse, and diversion among this population. PMID:17913395

Life course theory considers events in study and work as potential turning points in deviance, including illicit drug use. This qualitative study explores the role of occupational life in cannabis use and dependence in young adults. Two and three years after the initial structured interview, 47 at baseline frequent cannabis users were interviewed in-depth about the dynamics underlying changes in their cannabis use and dependence. Overall, cannabis use and dependence declined, including interviewees who quit using cannabis completely, in particular with students, both during their study and after they got employed. Life course theory appeared to be a useful framework to explore how and why occupational life is related to cannabis use and dependence over time. Our study showed that life events in this realm are rather common in young adults and can have a strong impact on cannabis use. While sometimes changes in use are temporary, turning points can evolve from changes in educational and employment situations; an effect that seems to be related to the consequences of these changes in terms of amount of leisure time and agency (i.e., feelings of being in control).

HIV infection is prevalent among substance abusers. The effects of specific illicit drugs on HIV disease progression have not been established. We evaluated the relationship between substances of abuse and HIV disease progression in a cohort of HIV-1-positive active drug users. A prospective, 30-month, longitudinal study was conducted on 222 HIV-1 seropositive drug users in Miami, FL. History of illicit drug, alcohol, and medication use, CD4+ cell count, and viral load were performed every 6 months. Crack-cocaine users were 2.14 times [95% confidence interval (CI): 1.08 to 4.25, P = 0.029] more likely to present a decline of CD4 to users (beta = 0.315, P = 0.037) independent of highly active antiretroviral therapy (HAART) over time. The only multidrug combination that significantly increased the risk of disease progression was crack cocaine with marijuana (hazard ratio = 2.42; 95% CI: 1.042 to 5.617, P = 0.04). Of those on HAART, a significantly lower proportion of crack-cocaine users versus nonusers had controlled viral load (P < 0.001), suggesting lower medication adherence, whereas crack-cocaine users not on HAART showed a greater risk for HIV disease progression than nonusers (hazard ratio = 3.946; 95% CI: 1.049 to 14.85, P = 0.042). Crack-cocaine use facilitates HIV disease progression by reducing adherence in those on HAART and by accelerating disease progression independently of HAART.

Examining the relationship between ethnicity and the use of drug-related services: an ethnographic study of Nepali drug users in Hong Kong

Tang, Wai-Man

2014-01-01

A recent survey has shown that Nepali drug users in Hong Kong tend to have a low rate of usage of day-care and residential rehabilitation services, but a high rate of usage of methadone services. Little is known about the reasons behind such a pattern. Therefore, in this study, a 12-month ethnographic examination has been implemented in three sites, including a day-care center, residential rehabilitation center, and methadone clinic, to explore the experiences of 20 Nepali drug users in their use of drug-related services in Hong Kong and to examine the relationship between ethnicity and the use of drug-related services. The result shows that the reason for this pattern of service use is related to the approach of the services and the cultural perception of the service providers about the service users. The day-care and residential rehabilitation services emphasize an integrated approach, but the staff tend to overlook the heterogeneity of their clients, for example, the differences in caste and sex, and fail to provide suitable services to them, whereas the methadone service follows a biomedical model, which seldom addresses the social characteristics of the service users, which in turn minimizes the opportunity for misunderstandings between the staff and the clients. This research shows that ethnicity is a significant factor in drug treatment and that culture-specific treatment that takes into consideration the treatment approach and the heterogeneity of the clients is strongly needed.

Existing research has demonstrated the significance of situational antecedents to substance use. The current study used a cluster analytic approach to identify groups of club drug users who report using substances in similar situations (assessed by the Inventory of Drug Taking Situations) with longitudinal data from 400 active drug users. A three-cluster solution emerged in baseline data and was replicated in 12-month follow-up data. Groups were identified as Situationally Restricted, Pleasure Driven, and Situationally Broad users. Group differences were observed on measures of mental health, attitudes towards substance use, amount of substance use, and rates of substance dependence. Cluster membership predicted substance dependence after controlling for past dependence, current use, and current depression/anxiety. PMID:20696530

Enhancing HIV Vaccine Trial Consent Preparedness Among Street Drug Users

Fisher, Celia B.

2011-01-01

This research used open-ended and true-false questions to assess the preparedness of 96 ethnically diverse, economically and socially marginalized adult street drug users to consent to participate in HIV vaccine trials (HVT). Specific areas of consent vulnerability included misconceptions about: (1) the recuperative value and risk of vaccines in general; (2) the presence of the HIV virus within the vaccine and the possibility of contracting or transmitting HIV as a consequence of participation; (3) inclusion criteria and experimental blinds; and (4) distrust in the medical and research establishments. A brief HVT lesson administered to 30 participants was effective in correcting specific HVT knowledge misperceptions and increasing certain, but not all areas of HVT trust. Assessment of post-lesson responses to ethics-relevant questions provides information on respondents' attitudes toward AIDS safe behavior, research risks and benefits, monetary compensation, and willingness to participate. Implications for enhancing informed consent for HVT involving active drug users are discussed. PMID:20569151

Elderly users of fall-risk-increasing drug perceptions of fall risk and the relation to their drug use - a qualitative study.

The aim of the study was to explore how home-dwelling elderly who use fall-risk-increasing drugs (FRIDs) perceive their fall risk and how they relate this to their drug use. A qualitative study with 14 home-dwelling elderly FRID users between 65 and 97 years in Central Norway participating in semi-structured individual interviews. The data were analyzed thematically by using systematic text condensation. The main finding was that the informants did not necessarily perceive the use of FRIDs to be a prominent risk factor for falls. Some informants said they did not reflect upon drug use whatsoever and said they fully trusted their physician's choices. When either experiencing dizziness, fall episodes or by reading the patient information leaflet the informants said to either adjust their drug use or to contact their physician. Some felt rejected due to not getting their point across or their wish to alter the drug was not granted by the physician. Elderly FRID users did not necessarily relate their drug use to fall risk or struggled to present their perceived drug-related problems. Physicians need to regularly inform, monitor and assess the drug treatment when treating elderly with FRIDs.

Objective: The present study aimed at comparing the prevalence of major psychiatric disorders including major depressive disorder, bipolar disorder, schizophrenia, and generalized anxiety disorder between performance-enhancing drug users and nonuser bodybuilders. Moreover, the prevalence of major psychiatric disorders in bodybuilders was also reported. Method: In this study, 453 athletes were recruited from Bushehr bodybuilding gyms from February to May 2015. A structured questionnaire was used to collect the participants’ information, including demographic characteristics, sports’ status and performance-enhancing drug use. According to the condition of performance-enhancing drug use, the participants were divided into current users, non-current users, and nonusers. The psychiatric status of the participants was evaluated using DSM-IV diagnostic criteria for major depressive disorder, bipolar disorder, generalized anxiety disorder, and schizophrenia. We also asked about the acute psychotic disturbances after using performance-enhancing drugs, alcohol use, and history of aggressive behavior in bodybuilders. Data were analyzed using one-way analysis of variance and chi-square tests. Results: Prevalence of major depressive disorder, bipolar disorder, schizophrenia, generalized anxiety disorder, and the overall prevalence of psychiatric disorders in the bodybuilders was 19.7%, 3.8%, 1.5%, 16.6%, and 26.7%, respectively. After using performance-enhancing drugs, 33% of the bodybuilders had experienced acute psychological disturbances. There were no significant differences between current, non-current, and nonuser bodybuilding athletes in the measured psychiatric disorders. Conclusion: Prevalence of psychiatric disorders was not significantly different in performance-enhancing drug users and nonusers. Thus, it can be concluded that performance-enhancing drugs do not increase the risk of psychiatric disorders in bodybuilders. PMID:29472947

Alcohol and drug use among young adults driving to a drinking location.

Clubs that feature electronic music dance events (EMDEs) draw young adults aged 18-34 who are at high-risk for alcohol-related crashes to locations where alcohol sales are the principal source of revenue. Up to 30% of these attendees may also use drugs. This provides an important context in which to study driving arrangements that reflect concern with impaired driving. We explored whether drivers were using less alcohol and fewer drugs at exit than their passengers were and whether a driver for the group ever changed after consuming too much during the evening. Using biological measures of alcohol consumption (breath tests) and drug use (oral fluid tests), 175 drivers and 272 passengers were surveyed among young adults arriving at and departing from EMDEs in San Francisco. Upon exit from the drinking locations, only 20% of the drivers, compared to 47% of the passengers, had a high breath alcohol concentration (defined as a BrAC of .05 g/dL or greater). Further, there was evidence that drivers with high BrACs switched to passenger status on exit and former passengers with lower BrACs replaced those drivers. However, there were no differences in the prevalence of drug use among drivers and passengers. These findings suggest that the effort by young adult drivers to avoid alcohol-impaired driving appears to be reducing the number of drivers with high BrACs returning from drinking locations, such as EMDEs, by about one third. However, there is no similar pattern for drugged driving. Copyright © 2013 Elsevier Ireland Ltd. All rights reserved.

Co-use of cannabis and drugs other than cannabis (DOTC) influences the risk of experiencing cannabis disorders. Accordingly, we explored whether speed of transition to drug co-use, the number of DOTC used, and/or being an experimental cannabis-only user, a regular cannabis-only user, or a regular cannabis user who co-uses DOTC (i.e., cannabis-plus user) were associated with decision-making (DM), mental health disorder symptoms, or cannabis use-related characteristics. We analyzed baseline data from a sub-sample of 266 adolescent (ages 14 to 16) cannabis users (CU) participating in an ongoing longitudinal study. Assessments included semi-structured interviews, self-report questionnaires, and measures of drug use, DM (measured via the Iowa Gambling Task), mental health disorders, and cannabis use-related problems. Endorsing a larger number of mood disorders symptoms was associated with being a regular cannabis-plus user rather than a regular cannabis-only user (AOR = 1.08, C.I.95% 1.01, 1.15). Poorer DM was associated with a faster transition to co-use, such that for each one unit increase in DM performance, the years to onset of drug co-use increased by 1% (p = 0.032). Endorsing a larger number of cannabis use-related problems was positively associated with endorsing a larger number of DOTC used (p = 0.001). This study provides new evidence on the process of drug co-use among CU. Specifically, mood disorder symptoms were associated with use of DOTC among regular CU. Furthermore, poorer DM was associated with a faster transition to drug co-use. Poorer DM and mood disorder symptoms may aggravate or accelerate the onset of adverse consequences among adolescent CU.

The aim of this study was to analyse the prevalence and predictors of drug combinations increasing bleeding risk among warfarin users with and without Alzheimer's disease (AD). This retrospective observational study utilised data from the Finnish MEDALZ-2005 cohort. The MEDALZ-2005 study included all community-dwelling persons with a clinically verified diagnosis of AD at the end of 2005, and one comparison person without AD for each case. Data on drug use was collected from the Prescription Register. We included persons who were warfarin users during the study period 2006-2009. Drug combinations increasing bleeding risk with warfarin included selective serotonin reuptake inhibitors (SSRIs), non-steroidal anti-inflammatory agents (NSAIDs), other antithrombotic drugs and tramadol. Factors associated with combination use were investigated with logistic regression. During the follow-up, 3385 persons with AD and 4830 persons without AD used warfarin. Drug combinations increasing bleeding risk were more common in warfarin users with AD than without AD [35.9 and 30.5%, respectively (p < 0.0001)]. The most common combination was SSRIs and warfarin, which was more common among persons with AD (23.8%) than among persons without AD (10.9%). NSAIDs and warfarin combination was more common among persons without AD. Combination use was associated with AD, female gender, younger age, diabetes mellitus, rheumatoid arthritis and asthma/chronic obstructive pulmonary disease (COPD). Use of drug combinations increasing bleeding risk was more common among warfarin users with AD. Special attention should be paid to minimise the duration of concomitant use and to find safer alternatives without increased bleeding risk.

Epidemiological aspects of HCV infection in non-injecting drug users in the Brazilian state of Pará, eastern Amazon

PubMed Central

2014-01-01

Background Currently, sharing of drug paraphernalia is the main form of HCV transmission worldwide. In South America, consistent findings indicate that shared sniffing equipment is an important factor in the spread of HCV among non-injecting drug users. Epidemiological data on the status of HCV infection in illicit drug users in the Amazon region are scarce, although reports of clinical cases of hepatitis or pathologies associated with HCV infection in other population groups are numerous. Thereby, this study investigated the prevalence, genotype frequency, and epidemiological factors associated with HCV infection in non-injecting drug users in the state of Pará, eastern Amazon. Results During 2008–2011, 300 non-injecting drug users attending drug-treatment centers participated in this study. Most non-injecting drug users were male (63.7%). The mean age was 32.5 years. The non-injecting drugs most consumed were: cannabis (15.6%), cocaine paste (21.3%), and oxi cocaine (25.7%). Tobacco (60.9%) and alcohol (79.4%) were also commonly consumed. One hundred six (35.1%; CI 95%: 29.8 - 41.1) non-injecting drug users presented anti-HCV antibodies by EIA. The HCV-RNA prevalence was 28.0% (95% CI: 20.6 - 35.8). Genotypes 1 (76.9%) and 3 (23.1%) of HCV have been identified. A multivariate analysis demonstrated that HCV infection was independently associated with the following factors: “age (≥ 35 years)”, “tattoos”, “use of a needle or syringe sterilized at home”, “shared use of drug paraphernalia”, “uses drugs for more than 5 years”, and “use of drugs everyday”. Conclusions This study revealed a high prevalence of HCV infection in non-injecting drug users, and most infections are occasioned by genotype 1. Likely, HCV transmission is associated with the tattoos, the use of needle or syringe sterilized at home by people over the age of 35 years, and sharing, time and frequency of use of non-injecting drugs.

This article presents the partial results of a multicenter, qualitative study, which involved seven Latin-American countries and Canada. The results presented refer to Northern Rio de Janeiro (city), Brazil. The objective of the study was to describe the perspective of relatives/acquaintances of illicit drug users about protective and risk factors, prevention initiatives, treatment services, and legal aspects regarding illicit drugs. Interviews were performed with 99 individuals, who reported being affected by their relationship with an illicit drug user (relative or acquaintance), approaching their perspectives regarding the key-domains. Most participants were women (73.7%); relatives who used drugs were mostly men (78.2%); the most consumed drug was marijuana (77.8%). The highlighted protective factor was having recreational-sports activities in the community (88.9%), and the risk factor was curiosity for trying something new (94.4%). The main treatment services were Church Groups (51.5%), and participants stated that laws should be more punitive (82.8%). In conclusion, this information is essential to fight against drug use/abuse, showing that there is a need for actions that consider different perspectives at different levels.

Prevalence, correlates and patterns of heroin use among young adults in the United States.

The prevalence of heroin use, abuse, and dependence has increased considerably over the past decade. This increase has largely been driven by young adults (18-25years). This study aims to improve the understanding of heroin use among young adults by determining the prevalence, correlates, patterns and attitude of heroin use among young adults in the US. The 2011-2013 National Survey on Drug Use and Health was analyzed. Study population included 55,940 young adults with valid interviews. Self-reported lifetime, past-year and past-month use of heroin were examined. Descriptive statistics and adjusted odds ratios were estimated in accordance with the complex survey design. Of the respondents, 18.4 per 1000 (95% CI=16.8-20.0) used heroin at some time in their lives, and 7.3 per 1000 (95% CI=6.3-8.3) and 3.3 per 1000 (95% CI=2.6-4.0) used heroin in the past year and past month, respectively. The single most common route of heroin use was by sniffing. Majority of young adults reported using heroin in combination with other substances. Users of non-prescribed opioid pain relievers, cigarette smokers, illicit drug users and those arrested and booked for breaking the law, had higher odds of using heroin during their lifetime, in the past-year and past-month. Fewer than 2% reported ever using heroin, and 82% of those reported no use in the past month. Majority were polysubstance users and sniffed heroin in combination with other routes of use. Comprehensive programs that target young adult heroin users and address important risk factors for heroin use are needed. Copyright © 2016 Elsevier Ltd. All rights reserved.

Despite extensive research into the determinants of electronic nicotine delivery system (ENDS) uptake, few studies have examined the psychosocial benefits ENDS users seek and experience. Using a consumer ritual framework, we explored how ENDS users recreated or replaced smoking practices, and considered implications for smoking cessation. In-depth interviews; data analysed using thematic analysis. Dunedin, New Zealand. 16 young adult ENDS users (age M=21.4, SD=1.9; 44% female). Participants reported using different ENDS to achieve varying outcomes. Some used 'cigalikes' to recreate a physically and visually similar experience to smoking; they privileged device appearance over nicotine delivery. In contrast, others used personally crafted mods to develop new rituals that differentiated them from smokers and showcased their technical expertise. Irrespective of the device they used, several former smokers and dual users of cigarettes and ENDS experienced strong nostalgia for smoking attributes, particularly the elemental appeal of fire and the finiteness of a cigarette. Non-smoking participants used ENDS to maintain social connections with their peers. Participants used ENDS to construct rituals that recreated or replaced smoking attributes, and that varied in the emphasis given to device appearance, nicotine delivery, and social performance. Identifying how ENDS users create new rituals and the components they privilege within these could help promote full transition from smoking to ENDS and identify those at greatest risk of dual use or relapse to cigarette smoking.

This study investigated risk and protective factors for recreational and hard drug use in Malaysian adolescents and young adults. Participants (n = 859; M age = 17.24 years, SD = 2.75 years, range = 13-25 years; 59% male) were recruited from secondary schools, technical colleges, a juvenile detention center and a national training center in Malaysia. A version of the Communities That Care survey validated for use in Malaysia (Razali & Kliewer, 2015) was used to assess study constructs. One in 6 adolescents and 1 in 3 young adults reported lifetime recreational and hard drug use, with greater use reported by males across all drug categories. Structural equation modeling was used to determine the strongest risk and protective factors for recreational and hard drug use. The overall pattern of findings was similar for recreational and hard drug use. Shared risk factors for lifetime recreational and hard drug use included early initiation of antisocial behavior, peer antisocial behavior, and peer reinforcement for engaging in antisocial behavior; shared protective factors included religious practices and opportunities for prosocial school involvement. Multiple group analyses comparing adolescents and young adults indicated that patterns of risk and protective factors predicting drug use differed across these age groups. There were fewer significant predictors of either recreational or hard drug use for young adults relative to adolescents. Results suggest that interventions should target multiple microsystems (e.g., peer groups, family systems, school environments) and be tailored to the developmental stage of the individual.

These analyses assess contextual profiles of 612 young adult Ecstasy users, 18–30 years of age, from St. Louis (USA), Miami (USA) and Sydney (Australia). Bivariate analyses revealed different contextual factors influencing Ecstasy use. Friends were the most common sources of Ecstasy at all sites and most used with friends. St. Louis and Miami use mostly occurred in residences, whereas in Sydney use was mostly at clubs, bars or restaurants. Ecstasy consumption at public places and in cars, trains or ferries was significantly higher in Miami (89% and 77%) than in St. Louis (67% and 65%) and Sydney (67% and 61%). At all sites, simultaneous use of LSD/mushroom and nitrous oxide with Ecstasy was common; concurrent amphetamines predominated in Sydney and heroin/opiates in St. Louis Contextual factors influencing Ecstasy use among young adults vary by geographic region. Their inclusion may help tailor effective prevention programs to reduce or ameliorate Ecstasy use. PMID:21094585

Social discrimination may isolate drug users into higher risk relationships, particularly in disadvantaged neighborhood environments where drug trade occurs. We used negative binomial regression accounting for clustering of individuals within their recruitment neighborhood to investigate the relationship between high-risk drug ties with various forms of social discrimination, neighborhood minority composition, poverty and education. Results show that experiencing discrimination due to drug use is significantly associated with more drug ties in neighborhoods with fewer blacks. Future social network and discrimination research should assess the role of neighborhood social cohesion.

Comparison of Homeless and Non-Homeless Problem Drug Users Recruited from Primary Care Safety-Net Clinics.

PubMed

Krupski, Antoinette; Graves, Meredith C; Bumgardner, Kristin; Roy-Byrne, Peter

2015-11-01

The present study of homeless non-treatment-seeking problem drug users was designed to complement and extend previous studies which focused exclusively on treatment-seeking homeless problem drug users. Data were available for 866 primary care patients with drug problems, 30% homeless and 70% housed. In the 2 years prior to baseline, homeless participants had less chronic medical co-morbidity than problem drug users who were housed yet were significantly more likely to have used emergency department services, to have used them more frequently, and at higher cost. Compared to their housed counterparts, homeless participants were also more likely to have been admitted to specialized chemical dependency treatment and/or detoxification services, to have been arrested for a felony or gross misdemeanor, and to report having psychiatric problems in the prior 30 days. Additional support may be necessary for homeless patients presenting in primary care to benefit from substance abuse treatment given their more severe drug use problems coupled with their co-morbid health, psychiatric, and psychosocial problems.

Caring for HIV/AIDS patients and/or drug users requires health care workers (HCWs) to have good knowledge of the issues. Cultural differences in HCWs, combined with professional ethics and personal beliefs, could also result in conflicting attitudes, leading to difficulties related to looking after people affected by HIV/AIDS or drug users. A cross-sectional study was carried out to assess the attitude towards HIV/AIDS patients and/or drug users in a sample of workers operating in a large university hospital in southern Italy. A total of 736 workers were surveyed from May to November 2016. During the periodic occupational health surveillance, a questionnaire was administered about attitudes of discrimination, acceptance and fear towards these patients. Respondents showed average levels of acceptance to HIV/AIDS and drug user patients. As years of experience and professional training increased, scores for discrimination, acceptance of HIV/AIDS, acceptance of drug users and fear decreased. Factors positively influencing levels of attitudes were being female and younger. Supplementary education is needed to strengthen the awareness of HCWs.

Adaptation and Validation of the Sexual Assertiveness Scale (SAS) in a Sample of Male Drug Users.

Vallejo-Medina, Pablo; Sierra, Juan Carlos

2015-04-21

The aim of the present study was to adapt and validate the Sexual Assertiveness Scale (SAS) in a sample of male drug users. A sample of 326 male drug users and 322 non-clinical males was selected by cluster sampling and convenience sampling, respectively. Results showed that the scale had good psychometric properties and adequate internal consistency reliability (Initiation = .66, Refusal = .74 and STD-P = .79). An evaluation of the invariance showed strong factor equivalence between both samples. A high and moderate effect of Differential Item Functioning was only found in items 1 and 14 (∆R 2 Nagelkerke = .076 and .037, respectively). We strongly recommend not using item 1 if the goal is to compare the scores of both groups, otherwise the comparison will be biased. Correlations obtained between the CSFQ-14 and the safe sex ratio and the SAS subscales were significant (CI = 95%) and indicated good concurrent validity. Scores of male drug users were similar to those of non-clinical males. Therefore, the adaptation of the SAS to drug users provides enough guarantees for reliable and valid use in both clinical practice and research, although care should be taken with item 1.

Limited research has focused on prescription drug misuse among young men who have sex with men (YMSM), or investigated risk factors contributing to misuse. This study aims to investigate the relationship between multiple psychosocial risk factors (i.e., childhood abuse, discrimination, mental health distress) and prescription drug misuse among YMSM who are current substance users. YMSM (N=191) who reported prescription drug misuse in the past 6 months were recruited in Philadelphia between 2012 and 2013 to complete an anonymous survey assessing demographic information, substance use, and psychosocial factors. High levels of childhood physical abuse and perceived stress were associated with higher opioid misuse, while high levels of depression were associated with lower misuse of opioids. Those with higher levels of perceived stress were more likely to report higher tranquilizer misuse, while those with more experiences of social homophobia/racism and higher levels of depression and somatization reported higher stimulant misuse. Regarding demographic correlates, older participants were more likely than younger participants to report higher opioid misuse, while racial minorities were less likely than White participants to report higher misuse of tranquilizers, stimulants, and illicit drug use. Bisexual/heterosexual/other identified participants were more likely than gay identified participants to report higher misuse of all three classes of prescription drugs. Associations of risk factors with substance use among YMSM are complex and offer opportunities for additional research. Our findings show that prevention efforts must address substance use among YMSM in sync with psychosocial stressors. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

Brain stem evoked response audiometry of former drug users.

Illicit drugs are known for their deleterious effects upon the central nervous system and more specifically for how they adversely affect hearing. This study aims to analyze and compare the hearing complaints and the results of brainstem evoked response audiometry (BERA) of former drug user support group goers. This is a cross-sectional non-experimental descriptive quantitative study. The sample consisted of 17 subjects divided by their preferred drug of use. Ten individuals were placed in the marijuana group (G1) and seven in the crack/cocaine group (G2). The subjects were further divided based on how long they had been using drugs: 1 to 5 years, 6 to 10 years, and over 15 years. They were interviewed, and assessed by pure tone audiometry, acoustic impedance tests, and BERA. No statistically significant differences were found between G1 and G2 or time of drug use in absolute latencies and interpeak intervals. However, only five of the 17 individuals had BERA results with adequate results for their ages. Marijuana and crack/cocaine may cause diffuse disorders in the brainstem and compromise the transmission of auditory stimuli regardless of how long these substances are used for.

Frequency and structure of stimulant designer drug consumption among suspected drug users in Budapest and South-East Hungary in 2012-2013.

Identification of abuse and frequency patterns of stimulant designer drugs (SDDs) provides important information for their risk assessment and legislative control. In the present study urine and/or blood samples of suspected drug users in criminal cases were analysed by GC-MS for 38 SDDs, and for the most frequent illicit and psychoactive licit drugs in Hungary. Between July 2012 and June 2013, 2744 suspected drug users were sampled in Budapest and during 2012 and 2013, 774 persons were sampled in South-East Hungary (Csongrád County - neighbour the Romanian and Serbian borders). In Budapest 71.4% of cases, and in South-East Hungary 61% of cases were positive for at least one substance. Pentedrone was the most frequent SDD in both regions; however, the frequency distribution of the remaining drugs was highly diverse. SDDs were frequently present in combination with other drugs - generally with amphetamine or other stimulants, cannabis and/or benzodiazepines. The quarterly distribution of positive samples indicated remarkable seasonal changes in the frequency and pattern of consumption. Substances placed on the list of illicit drugs (mephedrone, 4-fluoro-amphetamine, MDPV, methylone, 4-MEC) showed a subsequent drop in frequency and were replaced by other SDDs (pentedrone, 3-MMC, methiopropamine, etc.). Newly identified compounds from seized materials were added to the list of new psychoactive substances ("Schedule C"). While the risk assessment of substances listed in Schedule C has to be performed within 2 years after scheduling, continuous monitoring of their presence and frequency among drug users is essential. In summary, our results suggest which substances should be dropped from the list of SDDs measured in biological samples; while the appearance of new substances from seized materials indicate the need for developing adequate standard analytical methods.

The increasing health problem of hepatitis C virus infection has only recently attracted the attention of psychosocial research, especially among subjects at higher risk (e.g. injecting drug users). There is a lack of information about the knowledge, perceptions and feelings that injecting drug users hold about their hepatitis C antibody positive…

Concepts of illicit drug quality among darknet market users: Purity, embodied experience, craft and chemical knowledge.

PubMed

Bancroft, Angus; Scott Reid, Peter

2016-09-01

Users of darknet markets refer to product quality as one of the motivations for buying drugs there, and vendors present quality as a selling point. However, what users understand by quality and how they evaluate it is not clear. This article investigates how users established and compared drug quality. We used a two-stage method for investigating users' assessments. The user forum of a darknet market that we called 'Merkat' was analysed to develop emergent themes. Qualitative interviews with darknet users were conducted, then forum data was analysed again. To enhance the applicability of the findings, the forum was sampled for users who presented as dependent as well as recreational. Quality could mean reliability, purity, potency, and predictability of effect. We focused on the different kinds of knowledge users drew on to assess quality. These were: embodied; craft; and chemical. Users' evaluations of quality depended on their experience, the purpose of use, and its context. Market forums are a case of indigenous harm reduction where users share advise and experiences and can be usefully engaged with on these terms. Copyright © 2015 Elsevier B.V. All rights reserved.

Party drugs - use and harm reduction.

PubMed

Frei, Matthew

2010-08-01

Party drug use, the intermittent use of stimulants, ecstasy and so-called 'designer drugs' at dance parties or 'raves', is now part of the culture of many young Australians. This article discusses the risks associated with the use of 'party drugs' and describes an useful approach to general practitioner assessment and management of patients who may be using party drugs. Party drug use is associated with a range of harms, including risks associated with behaviour while drug affected, toxicity and overdose, mental health complications and physical morbidity. Multiple substance use, particularly combining sedatives, further amplifies risk. If GPs have some understanding of these drugs and their effects, they are well placed to provide an effective intervention in party drug users by supporting the reduction of harm.

2013-01-01

In the last decade we have observed a considerable increase in nonmedical usage of dextromethorphan (DXM) among young age groups, especially school children between 13 and 16 yrs. We analysed the "trip reports" after use of DXM, available on a website: www.hyperreal.info in the years 1999-2013. The data collected by authors were analysed according to: age, sex, symptoms, dose of DXM, a reason and a place of using the drug. A review of 124 "trip reports" showed that the majority of their writers are male (M 90.3%, F 9.7%). Young people, aged 16-20 (80.4%), dominated among the study population. The most common place of using DXM was a flat of a drug user (70.2%), and the reason of using a willingness to experiment with new psychoactive substances (41.9%) as well as the desire of "get high" (25.8%). The majority of users used DXM at least once again in their lives (56.5%). A single dose of the ingested drug ranged from 120 mg to 1575 mg (mean 539.25 mg). Most often received doses were 450 mg (30.4%), 300 mg (12%), 900 mg (11.2%). DXM was positively assessed by the internauts as a recreational psychoactive substance (84.7%). The most common clinical symptoms described by internauts were: difficulties with walking (74.2%), visual illusions (73.4%), altered sense of time (41.9%), feeling of exteriorisation (35.5%), euphoria (33.1%), nausea and vomiting (32.3%), auditory illusions (30.6%) and pruritus (29.8%). 1. DXM is the popular psychoactive substance which has gained a positive opinion among the Internet users. 2. Easy accessibility of DXM may pose a serious threat to health of young people who experiment with psychoactive substances. 3. The improvement of DXM sales control should be considered.

The income-generating behaviour of injecting drug-users in Oslo.

Bretteville-Jensen, A L; Sutton, M

1996-01-01

Drug users' income-generating behaviours, such as prostitution, acquisitive crime and small-scale dealing, have a major influence on the harm caused to the non-using population. Using data on the drug use and income sources of 900 drug-injectors in Oslo, this paper has two aims: to present data on Oslo income-generating behaviours and compare these with those in the Netherlands and Scotland; and to explore conceptual issues in the comparison of self-reported dealing income with other sources. Eighty-three per cent of respondents reported income from social benefit, and 43% had sold drugs in the last month. Half the females reported income from prostitution. The income-generation differences found in the comparisons section do not seem to reflect variations in drug and other social policies, but may relate to differences in the profitability of dealing. Using self-reported dealing income to compare the contributions of different income sources may be misleading, however, since it does not reflect financial profit or the value of dealers' drug consumption. Adjusted figures show that theft accounts for 23% of total drugs expenditure, while the corresponding figures for dealing and prostitution are 42% and 21%, respectively.

Vitamin A levels and human immunodeficiency virus load in injection drug users.

Semba, R D; Farzadegan, H; Vlahov, D

1997-01-01

Although low plasma vitamin A levels are associated with increased mortality and higher vertical transmission during human immunodeficiency virus (HIV) infection, it is unknown whether plasma low vitamin A levels are a marker for circulating HIV load. We conducted a cross-sectional study within a prospective cohort study of injection drug users in order to evaluate the relationship between plasma vitamin A levels and HIV viral load. Plasma vitamin A level was measured by high-performance liquid chromatography. Infectious viral load was measured by quantitative microculture of serial fivefold dilutions of 10(6) peripheral blood mononuclear cells. A total of 284 HIV-infected adults (79 women, 205 men) were studied. Plasma vitamin A levels consistent with deficiency were found in 28.9% of adults. A total of 38.0% of women and 25.3% of men had vitamin A deficiency (P < 0.04). The median infectious viral load for the entire study population was 8 infectious units per million cells. No significant relationship between plasma vitamin A levels and infectious viral load was observed in these injection drug users. This study suggests that there is no correlation between HIV viral load and plasma vitamin A levels in injection drug users, and these variables may represent independent risk factors during HIV infection. HIV-infected adult women appear to be at higher risk of developing vitamin A deficiency. PMID:9008289
