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. PMID:11853137

Injection drug users constitute the largest group of persons infected with the hepatitis C virus (HCV) in the United States, and most new infections occur in drug users. Controlling hepatitis C in the U.S. population, therefore, will require developing, testing, and implementing effective prevention and treatment strategies for persons who inject drugs. Fortunately, a substantial body of research and clinical experience exists on the prevention and management of chronic viral diseases among injection drug users. The need to implement interventions to stop the spread of HCV among drug users is critical. The capacity of substance-use treatment programs need to be expanded to accommodate all who want and need treatment. Physicians and pharmacists should be educated in how to provide access to sterile syringes and to teach safe injection techniques, both of which are lifesaving interventions. The treatment of hepatitis C in drug users requires an interdisciplinary approach that brings together expertise in treating hepatitis and caring for drug users. Treatment decisions should be made individually by patients with their physicians, based on a balanced assessment of risks and benefits and the patient's personal values. Physicians should carefully assess, monitor, and support adherence and mental health in all patients, regardless of whether drug use is known or suspected. Research is needed to better understand how best to prevent and treat hepatitis C in substance users. In the meantime, substantial progress can be made if existing knowledge and resources are brought to bear. PMID:12407596

The study examined the drug patterns and attitudes of a heavy marijuana user sample drawn from the local "counter-culture." The results indicate that the heavier marijuana user has a different subjective attitude and perception of the drug's effect than a light user. Second, multiple drug usage is, in general, the current and accepted mode within the sample. Finally, it appears that age of initial usage of a specific agent, duration, frequency of usage, and perceived drug effects may be dependent variables with reference to heavy marijuana and multiple drug usage. With respect to these variables, the question arises concerning what proportion of lighter drug using samples may, with time, adopt heavier and more varied drug patterns. PMID:1254370

BACKGROUND: In Canada, more than 70% of new cases of hepatitis C virus (HCV) infection per year involve injection drug users (IDUs) and, currently, there is no consensus on how to offer them medical care. OBJECTIVE: To examine the characteristics of Canadian specialist physicians and their likelihood to provide treatment to HCV patients who are IDUs. METHODS: A nationwide, cross-sectional study was conducted in the specialty areas of hepatology, gastroenterology and infectious diseases to examine HCV services. The questionnaire requested information regarding basic demographics, referral pathways and opinions (yes/no), and examined how a physician’s treatment regimen is influenced by factors such as treatment eligibility, HCV care management and barriers to providing quality service. RESULTS: Despite the fact that the majority of prevalent and incident cases of HCV are associated with injection drug use, very few specialist physicians actually provide the necessary therapy to this population. Only 19 (19.79%) comprehensive service providers were likely to provide treatment to a current IDU who uses a needle exchange on a regular basis. The majority of comprehensive service providers (n=86 [89.58%]) were likely to provide treatment to a former IDU who was stable on substitution therapy. On bivariate analysis, factors associated with the likelihood to provide treatment to current IDUs included physicians’ type, ie, infectious disease specialists compared with noninfectious specialists (OR 3.27 [95% CI 1.11 to 9.63]), and the size of the community where they practice (OR 4.16 [95% CI 1.36 to 12.71] [population 500,000 or greater versus less than 500,000]). Results of the multivariate logistic regression analysis were largely consistent with the results observed in the bivariate analyses. After controlling for other confounding variables, only community size was significantly associated with providing treatment to current IDUs (OR 3.89 [95% CI 1.06 to 14

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. PMID:26595006

The aim of this study was to identify mental health care technologies for treating crack users in a Psychosocial Care Center for Alcohol and other Drugs (CAPsad, as per its acronym in Portuguese). A qualitative, evaluative case study was developed in a CAPSad, using fourth generation evaluation. Data collection occurred from January to March 2013 by means of semi-structured interviews applied to 36 subjects, these being health care professionals, patients, patients' relatives and managers. Data analysis identified the category strategies in mental health work. Results showed that recovery programs should provide spaces for dialogue, aiming to clarify the process of psychiatric internment to the user and family, and involve these in the therapy, implementing educational practices and ongoing consideration of mental health activities. In conclusion, it is important to discuss the technologies used in everyday care services, in light of the complexity of crack use. PMID:26098808

To better understand patterns of drug use trajectories over time, it is essential to have standard measures of change. Our goal here is to introduce measures we developed to quantify change in drug use behaviors. A secondary goal is to provide effective visualizations of these trajectories for applied use. We analyzed data from a sample of 92 older drug users (ages 45 to 65) to identify transition patterns in drug use trajectories across the life course. Data were collected for every year since birth using a mixed methods design. The community-drawn sample of active and former users were 40% female, 50% African American, and 60% reporting some college or greater. Their life histories provided retrospective longitudinal data on the diversity of paths taken throughout the life course and changes in drug use patterns that occurred over time. Bayesian analysis was used to model drug trajectories displayed by innovative computer graphics. The mathematical techniques and visualizations presented here provide the foundation for future models using Bayesian analysis. In this paper we introduce the concepts of transition counts, transition rates and relapse/remission rates, and we describe how these measures can help us better understand drug use trajectories. Depicted through these visual tools, measurements of discontinuous patterns provide a succinct view of individual drug use trajectories. The measures we use on drug use data will be further developed to incorporate contextual influences on the drug trajectory and build predictive models that inform rehabilitation efforts for drug users. Although the measures developed here were conceived to better examine drug use trajectories, the applications of these measures can be used with other longitudinal datasets. PMID:21743792

Background Urinary schistosomiasis is caused by an intravascular infection with parasitic Schistosoma haematobium worms. The adult worms typically migrate to the venous plexus of the human bladder and excrete eggs which the infected person passes in their urine. Chronic infection can cause substantial morbidity and long-term complications as the eggs become trapped in human tissues causing inflammation and fibrosis. We summarised evidence of drugs active against the infection. This is new edition of a review first published in 1997. Objectives To evaluate the efficacy and safety of drugs for treating urinary schistosomiasis. Search methods We searched the Cochrane Infectious Diseases Group Specialized Register, MEDLINE, CENTRAL, EMBASE and LILACS and reference lists of articles up to 23 May 2014. Selection criteria Randomized controlled trials (RCTs) of antischistosomal drugs and drug combinations compared to placebo, no intervention, or each other. Data collection and analysis Two researchers independently screened the records, extracted the data and assessed risk of bias. The primary efficacy outcomes were parasitological failure (defined as the continued presence of S. haematobium eggs in the urine at time points greater than one month after treatment), and percent reduction of egg counts from baseline. We presented dichotomous data as risk ratios (RR), and continuous data as mean difference (MD), alongside their 95% confidence intervals (CIs). Where appropriate we combined trials in meta analyses or tables. We assessed the quality of evidence using the GRADE approach. Main results We included 30 RCTs enrolling 8165 participants in this review. Twenty-four trials were conducted in children in sub-Saharan Africa, and 21 trials were over 20 years old. Many studies were assessed as being at unclear risk of bias due to inadequate descriptions of study methods.

Background Cholera is an acute watery diarrhoea caused by infection with the bacterium Vibrio cholerae, which if severe can cause rapid dehydration and death. Effective management requires early diagnosis and rehydration using oral rehydration salts or intravenous fluids. In this review, we evaluate the additional benefits of treating cholera with antimicrobial drugs. Objectives To quantify the benefit of antimicrobial treatment for patients with cholera, and determine whether there are differences between classes of antimicrobials or dosing schedules. Search methods We searched the Cochrane Infectious Disease Group Specialized Register; the Cochrane Central Register of Controlled Trials (CENTRAL); PubMed; EMBASE; African Index Medicus; LILACS; Science Citation Index; metaRegister of Controlled Trials; WHO International Clinical Trials Registry Platform; conference proceedings; and reference lists to March 2014. Selection criteria Randomized and quasi-randomized controlled clinical trials in adults and children with cholera that compared: 1) any antimicrobial treatment with placebo or no treatment; 2) different antimicrobials head-to-head; or 3) different dosing schedules or different durations of treatment with the same antimicrobial. Data collection and analysis Two reviewers independently applied inclusion and exclusion criteria, and extracted data from included trials. Diarrhoea duration and stool volume were defined as primary outcomes. We calculated mean difference (MD) or ratio of means (ROM) for continuous outcomes, with 95% confidence intervals (CI), and pooled data using a random-effects meta-analysis. The quality of evidence was assessed using the GRADE approach. Main results Thirty-nine trials were included in this review with 4623 participants. Antimicrobials versus placebo or no treatment Overall, antimicrobial therapy shortened the mean duration of diarrhoea by about a day and a half compared to placebo or no treatment (MD -36.77 hours, 95% CI -43

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.

Infected aneurysms of the pulmonary artery are a rare consequence of injected drug use. Hemoptysis of pulmonary arterial origin is also infrequent; however, the mortality is as high as 50%. We report here a case of hemoptysis in an intravenous drug user, caused by a pulmonary artery aneurysm due to septic microemboli, originating from a groin abscess. We highlight the importance of recognizing and treating thromboembolic complications associated with deep venous thrombosis in injecting drug users. PMID:23250844

The indole alkaloid ibogaine, present in the root bark of the West African rain forest shrub Tabernanthe iboga, has been adopted in the West as a treatment for drug dependence. Treatment of patients requires large doses of the alkaloid to cause hallucinations, an alleged integral part of the patient's treatment regime. However, case reports and case series continue to describe evidences of ataxia, gastrointestinal distress, ventricular arrhythmias and sudden and unexplained deaths of patients undergoing treatment for drug dependence. High doses of ibogaine act on several classes of neurological receptors and transporters to achieve pharmacological responses associated with drug aversion; limited toxicology research suggests that intraperitoneal doses used to successfully treat rodents, for example, have also been shown to cause neuronal injury (purkinje cells) in the rat cerebellum. Limited research suggests lethality in rodents by the oral route can be achieved at approximately 263mg/kg body weight. To consider an appropriate and safe initial dose for humans, necessary safety factors need to be applied to the animal data; these would include factors such as intra- and inter-species variability and for susceptible people in a population (such as drug users). A calculated initial dose to treat patients could be approximated at 0.87mg/kg body weight, substantially lower than those presently being administered to treat drug users. Morbidities and mortalities will continue to occur unless practitioners reconsider doses being administered to their susceptible patients. PMID:27426011
Background Gamma-hydroxybutyrate (GHB) and gamma-butyrolactone (GBL) have been profiled as 'party drugs' used mainly at dance parties and in nightclubs on weekend nights. The purpose of this study was to examine the frequency of injecting drug use among GHB/GBL overdose patients and whether there are temporal differences in the occurrence of GHB/GBL overdoses of injecting drug and recreational drug users. Methods In this retrospective study, the ambulance and hospital records of suspected GHB- and GBL overdose patients treated by the Helsinki Emergency Medical Service from January 1st 2006 to December 31st 2007 were reviewed. According to the temporal occurrence of the overdose, patients were divided in two groups. In group A, the overdose occurred on a Friday-Saturday or Saturday-Sunday night between 11 pm-6 am. Group B consisted of overdoses occurring on outside this time frame. Results Group A consisted of 39 patient contacts and the remaining 61 patient contacts were in group B. There were statistically significant differences between the two groups in (group A vs. B, respectively): history of injecting drug abuse (33% vs. 59%, p = 0.012), reported polydrug and ethanol use (80% vs. 62%, p = 0.028), the location where the patients were encountered (private or public indoors or outdoors, 10%, 41%, 41% vs. 25%, 18%, 53%, p = 0.019) and how the knowledge of GHB/GBL use was obtained (reported by patient/bystanders or clinical suspicion, 72%, 28% vs. 85%, 10%, p = 0.023). Practically all (99%) patients were transported to emergency department after prehospital care. Conclusion There appears to be at least two distinct groups of GHB/GBL users. Injecting drug users represent the majority of GHB/GBL overdose patients outside weekend nights. PMID:22296777

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 Eysenck Personality Questionnaire, the Sensation Seeking Scale, and the Brief Symptom Inventory were administered to 125 recovering drug users with three or more months abstinent from drugs. Subjects were divided according to drug preference: opiates, stimulants, marijuana, alcohol, and a polydrug preference. Opiate users were significantly higher in Susceptibility to Boredom. Alcohol misusers compared to a combined stimulant, opiate, and polydrug group were significantly lower in Extroversion and Susceptibility to Boredom. Subjects raised in drug/alcohol-using families scored significantly higher on Neuroticism and on the Positive Symptom Total of the BSI, and had a higher rate of suicidality. PMID:7601576

The purpose of this study is to use a modified version of Andersen’s (1968, 1995) Behavioral Model of Health Services Use to identify the correlates of the number of substance abuse treatment episodes received by rural drug users. Data were collected from face-to-face interviews with 711 drug users in rural areas of Ohio, Arkansas, and Kentucky. Descriptive analyses examine rural drug users’ substance use histories and retrospective substance abuse treatment service utilization patterns. A negative binomial regression model indicated that selected predisposing, historical health, and enabling factors were significantly associated with the utilization of substance abuse treatment among rural drug users. Despite high levels of recent and lifetime self-reported substance use among these rural drug users, treatment services were underutilized. Future studies are needed to examine the impact of the health care system and characteristics of the external environment associated with rural substance abuse treatment in order to increase utilization among drug users.

This paper's objective is to develop a method to estimate the total mortality among problem drug users. The total mortality is given by a base rate of mortality not related to drugs and the deaths that are directly and indirectly related to drugs. A fatal poisoning by drugs (overdose) is directly related to drugs, whereas a casualty due to a drug-related disease or a drug-related accident is indirectly related to drugs. As an example of a method to estimate the total mortality, the results from a cohort study among methadone patients in Amsterdam were projected on the whole population of problem drug users in The Netherlands. Due to differences between the problem drug users in Amsterdam and the rest of the country, adjustments were required. It was found that an initial estimation did not require adjustment for injection behavior and gender but did require adjustment for age and the percentage of HIV infection. In a first unadjusted estimation, the total number of deaths among problem drug users in The Netherlands in 2001 was estimated at 606 deaths. After adjustment for age, the estimated mortality decreased to 573 deaths, and after adjustment for HIV infection, this estimation again decreased to 479 deaths. From the ultimately estimated mortality, 11% was considered to be not related to drugs, 23% was attributed directly to drugs, and 66% was attributed indirectly to drugs. The number of direct deaths, as estimated by this method, falls in the same order of magnitude as the number extracted from the Causes of Death Statistics, when selecting cases according to the Drug-Related Deaths Standard as established by the European Monitoring Centre for Drugs and Drug Addiction (EMCDDA). Further cross-validation with other measures will be needed to assess the accuracy of the method, the limitations of which are discussed with respect to stipulating directions for future research.

Obesity is a disease that has historically eluded effective medical therapy. Prior to 2012, phentermine and orlistat were the only medications available to treat obesity in the USA, with phentermine approved only for short-term use. However, as of 2015, the repertoire of pharmacological agents available to treat obesity has greatly expanded to include four new drugs: lorcaserin, phentermine/topiramate extended release (ER), naltrexone ER/wellbutrin ER and liraglutide. Each has a unique mechanism of action and all are intended for long-term use. These newer medications share a common strategy to promote weight loss in that they are designed to manipulate the control of hunger and satiety in the central nervous system. Interestingly, the majority of these new agents are combinations of older medications that have been used for conditions other than obesity. The amount of weight loss seen with these agents beyond placebo varies but generally falls in the range of 3-10% of starting weight and requires continual use of the drug in order for weight loss to be sustained. In addition, each drug has a unique side effect profile that should be carefully considered when selecting the best agent for a given individual. This article provides a review of these recently approved medications focusing on efficacy, side effect profiles and appropriate application to the individual patient. PMID:27053517

Recent theories propose that repeated drug use is associated with attentional and evaluative biases for drug-related stimuli, and that these cognitive biases are related to individual differences in subjective craving. This study investigated cognitive biases for cannabis-related cues in recreational cannabis users. Seventeen regular cannabis users and 16 non-users completed a visual probe task which assessed attentional biases for cannabis-related words, and an implicit association test (IAT) which assessed implicit positive or negative associations for cannabis-related words. Results from the IAT indicated more negative associations for cannabis-related words in non-users compared to users. Among cannabis users, those with high levels of cannabis craving had a significant attentional bias for cannabis-related words on the visual probe task, but those with low levels of craving did not. Results highlight the role of craving in attentional biases for cannabis-related stimuli. PMID:15072814

Drug abuse has been widely linked to suicide risk. We examined the factors that affect adolescent drug users' suicide attempts in South Korea. This study analyzed the data of 311 adolescents who had used drugs such as inhalants, psychotropic drugs, and marijuana (195 males and 116 females). Among 311 subjects, 109 (35.0%) had attempted suicide during the last 12 months. After adjusting for other variables, depressive mood (OR=19.79) and poly-drug use (OR=2.79), and low/middle levels of academic achievement compared with a high level (OR=3.72 and 4.38) were independently associated with increased odds of a suicide attempt, while better perceived health (OR=0.32) was independently associated with reduced odds of a suicide attempt. For adolescent drug users, preventive work should be directed toward the active treatment of drug use, depression, and physical health and reinforcing proper coping strategies for academic and other stress.

Both lay persons and members of the scientific community have come to view the inner-city crack house as a facility where drug dealers and crack addicts sell, buy, and use crack cocaine. It is suggested in this article that the term "crack house" be unbundled into four more meaningful terms based on the physical conditions of the house, its functionality, and the social relationships that it supports. Two typologies are proposed. The first separates drug houses into four general categories: (1) Crack House, (2) Cop House, (3) Drug House III, and (4) Drug House IV.

The objective of this paper is to review the current status of drug use and HIV/AIDS prevention for drug users in China and provide scientific evidence for HIV/AIDS prevention and control in drug users. Literature and articles related to drug abuse in China, as well as the results of prevention efforts and successful cases regarding HIV/AIDS prevention in drug users, are reviewed. Lessons learned are drawn out for the future improvement of work and the sustainable development of treatment programs. The number of drug users in China is increasing. Even though the number of opioid-type drug users is growing more slowly than in the past, the number of amphetamine-type stimulant users has increased sharply. It has been proven that methadone maintenance treatment and syringe exchange programs gradually and successfully control HIV/AIDS transmission in drug users. However, it is necessary to enhance these prevention methods and expand their coverage. In addition, the strengthening of antiretroviral therapy (ART) treatment for HIV-infected drug users is crucial for HIV/AIDS prevention and control. The rapidly growing number of amphetamine-type stimulant users, along with their high-risk behavior, poses a hidden danger of greater HIV/AIDS transmission through sexual intercourse in the near future.

HIV/AIDS and chemical dependency, both of which are complicated by and intertwined with mental illness, are complex, overlapping spheres that adversely influence each other and the overall clinical outcomes of the affected individual . Each disorder individually impacts tens of millions of people, with explosive epidemics described worldwide. Drug users have increased age matched morbidity and mortality for a number of medical and psychiatric conditions. HIV/AIDS, with its immunosuppressed states and direct virologic effects, exacerbate morbidity and mortality further among HIV-infected drug users. This article addresses the adverse consequences of HIV/AIDS, drug injection, the secondary comorbidities of both, and the impact of immunosuppression on presentation of disease as well as approaches to managing the HIV-infected drug user.

Epilepsy is one of the most common neurologic disorders in dogs and life-long treatment with antiepileptic drugs (AED) is frequently required. Adverse events of AED targeting the skin are only rarely reported in veterinary medicine and the true incidence and spectrum of cutaneous reactions in epileptic dogs remains unknown. In this study, we hypothesized that cutaneous reactions commonly occur in epileptic dogs and are related to AED treatment. A retrospective case review of 185 dogs treated for epilepsy identified 20.0% with simultaneous appearance of dermatologic signs. In a subsequent prospective case investigation (n = 137), we identified newly appearing or distinct worsening of skin lesions following initiation of AED therapy in 10.9% of dogs treated for epilepsy (95% CI 6.8–17.7%). Cutaneous lesions were classified as probably drug-induced in 40.0% of these cases. Patch testing and intradermal testing were further investigated as potential diagnostic methods to confirm AED hypersensitivity. They were of high specificity but sensitivity and positive predictive value appeared inappropriate to recommend their routine use in clinical practice. PMID:27148543

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. PMID:27088708

The human T-cell lymphotropic virus, type III (HTLV-III) is the causative agent of acquired immunodeficiency syndrome (AIDS). Since AIDS is not curable, public health efforts must be focused on decreasing AIDS transmission. 72% of all AIDS cases are male homosexuals; 17% are intravenous (IV) drug users; and 3% are hemophiliacs, blood recipients, and infants of these groups. The gay community is sufficiently organized to provide the necessary infrastructure for AIDS education and treatment; the drug users are not, and at least 1/3 of IV drug users share needles and syringes. In 1984 a cooperative study was undertaken in New Jersey by the New Jersey State Department of Health, the National Cancer Institute (NCI), and the National Institute on Drug Abuse (NIDA) to determine the seroprevalence of HTLV-III among IV drug users and to assess their knowledge about AIDS. Over 95% knew the severer symptoms of AIDS; 76% knew that most AIDS patients die within 2 years of diagnosis; but 9% thought AIDS could be treated. A year later in 1985 a similar knowledge assessment survey was done among 577 clients entering drug treatment programs in New Jersey. 90% of these respondents knew that homosexuals and IV drug users were the primary risk groups, but 11% thought alcoholics were also at risk, and 43% did not know that the infants of drug users were at risk. 84% knew that sex and shared needles were the major modes of transmission, but 1/3 thought that an infected person would immediately show visible signs of illness, and many did not know how rapidly AIDS killed. Also, many did not know how to adequately clean syringes. They thought boiling would damage the syringes, and only 1/3 knew that a dilute solution of household bleach kills the virus. New Jersey decided to use indigenous health workers, recruited from rehabilitated drug users, to educate the drug community. The core message was: get treatment; don't share needles; and if you must share needles, clean them. The same

Seventy-two recent-onset injection drug users and 241 non-injection drug users were recruited in Quetta and Lahore, Pakistan, in 2003. Trained interviewers administered questionnaires regarding drug use behaviors and perceived changes in drug cost/supply. Logistic regression identified independent correlates of recent-onset injection. In Lahore, a perceived increase in drug cost was associated with higher odds of recent-onset injection, with no association in Quetta. Recent-onset injection was also associated with family history of drug use, group drug use, and sharing snorting/chasing tools. Changes in perception of the drug supply may be associated with recent-onset injection drug use. Familial/social influences were also associated with recent-onset injection, suggesting peer-led interventions could discourage transition to injection drug use. PMID:17613949

The purpose of this paper was to explore group drug taking behaviour in a slum area of Dhaka, Bangladesh. We set out to examine the relationships between those who met, at least weekly, to take illegal drugs together, and how these relationships might shape their drug behaviour. Sociometric and behavioural data were collected using questionnaires via semi-structured interviews. We found that the likelihood of injecting drugs and sharing needles increased with age, duration of group membership and length of drug use. Drug users were classified into two clusters: one was more cohesive and comprised longer-term users, who were more likely to inject drugs and had poorer physical and mental health. The other cluster comprised younger, better educated members who were more transient, less cohesive, less likely to inject drugs and had better health. Qualitative data suggested that members of the first cluster were less accepting of outsiders and confirmed more to group norms. We conclude that emotionally bonded cohesive subgroups acquire norms, which reinforce problematic drug-using behaviour. Thus, health initiatives need to consider group relationships and norms and those initiatives which work with networks may be more effective and more appropriate for low-income countries.

The purpose of this analysis was to examine the effect of social network cohesiveness on drug economy involvement, and to test whether this relationship is mediated by drug support network size in a sample of active injection drug users. Involvement in the drug economy was defined by self-report of participation in at least one of the following activities: selling drugs, holding drugs or money for drugs, providing street security for drug sellers, cutting/packaging/cooking drugs, selling or renting drug paraphernalia (e.g., pipes, tools, rigs), and injecting drugs in others' veins. The sample consists of 273 active injection drug users in Baltimore, Maryland who reported having injected drugs in the last 6 months and were recruited through either street outreach or by their network members. Egocentric drug support networks were assessed through a social network inventory at baseline. Sociometric networks were built upon the linkages by selected matching characteristics, and k-plex rank was used to characterize the level of cohesiveness of the individual to others in the social network. Although no direct effect was observed, structural equation modeling indicated k-plex rank was indirectly associated with drug economy involvement through drug support network size. These findings suggest the effects of large-scale sociometric networks on injectors' drug economy involvement may occur through their immediate egocentric networks. Future harm reduction programs for injection drug users (IDUs) should consider providing programs coupled with economic opportunities to those drug users within a cohesive network subgroup. Moreover, individuals with a high connectivity to others in their network may be optimal individuals to train for diffusing HIV prevention messages. PMID:25309015

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.

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.

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

Background Personality traits are considered risk factors for drug use, and, in turn, the psychoactive substances impact individuals' traits. Furthermore, there is increasing interest in developing treatment approaches that match an individual's personality profile. To advance our knowledge of the role of individual differences in drug use, the present study compares the personality profile of tobacco, marijuana, cocaine, and heroin users and non-users using the wide spectrum Five-Factor Model (FFM) of personality in a diverse community sample. Method Participants (N = 1,102; mean age = 57) were part of the Epidemiologic Catchment Area (ECA) program in Baltimore, MD, USA. The sample was drawn from a community with a wide range of socio-economic conditions. Personality traits were assessed with the Revised NEO Personality Inventory (NEO-PI-R), and psychoactive substance use was assessed with systematic interview. Results Compared to never smokers, current cigarette smokers score lower on Conscientiousness and higher on Neuroticism. Similar, but more extreme, is the profile of cocaine/heroin users, which score very high on Neuroticism, especially Vulnerability, and very low on Conscientiousness, particularly Competence, Achievement-Striving, and Deliberation. By contrast, marijuana users score high on Openness to Experience, average on Neuroticism, but low on Agreeableness and Conscientiousness. Conclusion In addition to confirming high levels of negative affect and impulsive traits, this study highlights the links between drug use and low Conscientiousness. These links provide insight into the etiology of drug use and have implications for public health interventions. PMID:18405382

Background Some orphan drugs can cost hundreds of thousands of dollars annually per patient. As a result, payer sensitivity to the cost of orphan drugs is rising, particularly in light of increased numbers of new launches in recent years. In this article, we examine payer coverage in the United States, England and Wales, and the Netherlands of outpatient orphan drugs approved between 1983 and 2012, as well as the 11 most expensive orphan drugs. Methods We collected data from drug regulatory agencies as well as payers and drug evaluation authorities. Results We found that orphan drugs have more coverage restrictions than non-orphan drugs in all three jurisdictions. From an economic perspective, the fact that a drug is an orphan product or has a high per-unit price per se should not imply a special kind of evaluation by payers, or necessarily the imposition of more coverage restrictions. Conclusion Payers should consider the same set of decision criteria that they do with respect to non-orphan drugs: disease severity, availability of treatment alternatives, level of unmet medical need, and cost-effectiveness, criteria that justifiably may be taken into account and traded off against one another in prescribing and reimbursement decisions for orphan drugs.

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.

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. PMID:20724686

The purpose of this study was to evaluate the attitudes of drug treatment program providers concerning human immunodeficiency virus (HIV) post-exposure therapy (PET) for drug users enrolled in drug treatment. This was a cross-sectional evaluation of drug treatment program providers in four methadone maintenance programs (MMPs) in New Haven, Connecticut. Thirty-five MMP providers including: 29 MMP treatment staff (physicians, nurses, counselors) and 6 primary care provider staff (physicians, nurse practitioners, and nurses) participated in the study. The providers were presented with four case vignettes of individuals exposed to HIV through a needle stick ("stick"): a phlebotomist with occupational exposure (Case A) and three drug users with nonoccupational exposure to HIV (Cases B, C, and D). Case B had the same estimated future risk as Case A (three sticks/4 years) and the other cases had increased risk: Case C (four to six sticks/year) and Case D (monthly "sticks"). For each vignette, providers were asked whether they would offer HIV PET ("yes" or "no"). In addition, focus groups were held within each group of providers who were asked: "What role should drug treatment programs play in the implementation of PET?" All MMP staff (29/29) and primary care providers (6/6) felt that the phlebotomist with occupational exposure should be offered PET. The percent of MMP and Primary care provider staff recommending PET for the other cases were: Case B (MMP staff: 86% [25/29], PCPs: 100% [6/6]), Case C (MMP staff: 69% [20/29], PCPs: 33% [2/6]), and Case D (MMP staff: 59% [17/29], PCPs: 17% [1/6]). The "common themes" that were identified in the focus groups included: concern that MMPs lack resources to provide PET, the ethics of withholding PET, the "limit" on the number of times PET should be offered, and the role of PET in the overall HIV prevention message. Both MMP staff and PCPs felt that MMPs should have an "indirect" role in providing HIV PET by providing education

The meaning and importance of implicit prejudice is a source of considerable debate. One way to advance this debate is to assess whether implicit prejudice can predict independent variance, beyond that predicted by explicit prejudice, in meaningful and unambiguous behaviors or behavioral intentions. In the current research, drug and alcohol nurses reported their level of stress working with injecting drug users, their job satisfaction, their explicit prejudice toward injecting drug users, and their intentions to leave drug and alcohol nursing. The nurses also completed the Single Category Implicit Association Test, which measured their implicit prejudice toward injecting drug users. Analyses revealed that implicit prejudice was a significant mediator, beyond explicit prejudice and job satisfaction, of the relation between job stress and intention to change jobs. PMID:18181783

A web-based survey was used to consult the opinions of experienced drug users on matters related to drug harms. We identified a rare sample of 93 drug users with personal experience with 11 different illicit drugs that are widely used in the UK. Asked to assess the relative harms of these drugs, they ranked alcohol and tobacco as the most harmful, and three "Class A" drugs (MDMA, LSD, and psilocybin) and one class B (cannabis) were ranked as the four least harmful drugs. When asked to assess the relative potential for benefit of the 11 drugs, MDMA, LSD, psilocybin, and cannabis were ranked in the top four; and when asked why these drugs are beneficial, rather than simply report hedonic properties, they referred to potential therapeutic applications (e.g., as tools to assist psychotherapy). These results provide a useful insight into the opinions of experienced drug users on a subject about which they have a rare and intimate knowledge. PMID:24377171

We examined correlates of ever injecting drugs in Mexico among residents of San Diego, California. From 2007 to 2010, injecting drug users (IDUs) in San Diego underwent an interviewer-administered survey. Logistic regression identified correlates of injection drug use in Mexico. Of 302 IDUs, 38% were Hispanic, 72% male and median age was 37; 27% ever injected in Mexico; 43% reported distributive syringe sharing there. Factors independently associated with ever injecting drugs in Mexico included being younger at first injection, injecting heroin, distributive syringe sharing at least half of the time, and transporting drugs over the last 6 months. One-quarter of IDUs reported ever injecting drugs in Mexico, among whom syringe sharing was common, suggesting possible mixing between IDUs in the Mexico-US border region. Prospective studies should monitor trends in cross-border drug use in light of recent Mexican drug policy reforms partially decriminalizing drug possession. PMID:21442300

The study described here investigates the replicability of gender-specific risk profiles for gonorrhea based on an Alaskan sample compared to a U.S. national sample of drug users at risk for HIV infection. The Alaska sample (interviewed at a field station in Anchorage, Alaska; N=1,049) and the national sample (interviewed at 18 sites other than Alaska; N=17,619) consisted of cocaine smokers and injection drug users not in drug treatment. A history of gonorrhea infection was self-reported and coded as ever or never. The Anchorage and national risk profile for men included the following factors: (a) history of intranasal or parenteral cocaine use, (b) being black versus nonblack, (c) being older, (d) income from illegal activity, and (e) history of amphetamine use. The Anchorage and national risk profiles for women included the following factors: (a) trading sex for money, (b) being Native American versus non-Native American, and (c) trading sex for drugs. The Anchorage model for women included perceived homelessness as a factor, but it was not retained in the national model. The extent of the replicability of these models illustrates the generalizability of Alaskan findings to other U.S. drug-using populations. The authors also discuss the implications of these findings for disease prevention. PMID:9643466

Design, setting and participants Datasets from China's national HIV/AIDS case reporting and sentinel surveillance systems as of December 2011 were used separately for descriptive analysis. Measures Changes in the geographic distribution of the number of HIV cases and HIV prevalence among injecting drug users (IDUs) and non-IDUs were examined. We also analyzed changes in HIV prevalence among the broader DU population, and drug use-related behaviors including types of drugs used, recent injecting, and recent needle sharing in the context of the rapid scale-up of DU sentinel sites and national harm reduction programs. Findings The HIV epidemic among China's DUs is still highly concentrated in five provinces. Here, HIV prevalence peaked at 30.3% (95% CI [28.6, 32.1]) among IDUs in 1999, and then gradually decreased to 10.9% (95% CI [10.6, 11.2]) by 2011. We observed a rapid increase in the use of “nightclub drugs” among DUs from 1.3% in 2004 to 24.4% in 2011. A decline in recent needle sharing among current IDU from 19.5% (95% CI [19.4, 19.6]) in 2006 to 11.3% (95% CI [11.2, 11.4]) in 2011 was found to be correlated with the rapid scale-up of methadone maintenance treatment (MMT; r(4) = - .94, p = 0.003) harm reduction efforts. Conclusions While needle sharing among current injecting drug users in China has declined dramatically and is correlated with the scale-up of national harm reduction efforts, the recent, rapid increased use of “nightclub drugs” presents a new challenge.

The French system for drug substitution, or maintenance treatment, established in 1996, differs from the often strict conditions attached to methadone clinics in other countries. Because of the predominant role of general practitioners and the flexible prescription rules for Subutex® in France, the relationship between the physician and the drug user becomes a central element in the treatment. This article deals with the expectations that these users have of the physician, and their perception of his or her attitude towards them. In order to identify possible reasons for the absence of treatment compliance and of Subutex® misuse, it focuses on the users’ assessment of the physician’s response to the problems they report. This study, based on a diversified sample of 28 persons in treatment, showed 4 patterns of relationships between physicians and users, which differed in their focus: a) dosage, b) compliance, c) the person and d) obtaining a prescription. In all four case types, users had difficulty reporting other drug use or intravenous Subutex® injection within this relationship in which the stigma attached to drug dependence seems to reappear. Moreover, the lack of clarity about the treatment objectives and time frame limits the users’ ability to integrate the treatment into their lives and to commit themselves to it. The heterogeneity and fragility of the users’ situations are elements related to dependence that, during contact with the physician, require regular assessment of the individual’s situation and of the treatment objectives. This constant reappraisal of the situation with the physician should help to optimize the treatment and avoid the hiatus that can generate or continue “misuse.” PMID:17442473

Background 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. Methods Six focus groups were conducted with 34 drug users recruited from syringe exchange programs and an HIV clinic between May and June 2012. Individual interviews were conducted with participants reporting previous genetic testing. Results 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. Conclusions 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.

Background Studies of individuals in treatment for substance use have found high rates of psychiatric disorders, however little is known about the mental health of drug users not in treatment. This study aimed to assess the prevalence of lifetime and recent substance use and psychiatric disorders among young injection drug users (IDU) outside of a treatment setting. Methods Participants were recruited through outreach and respondent-driven sampling. Trained interviewers administered the Psychiatric Research Instrument for Substance and Mental Disorders. Interviews were conducted at two field stations operated by Community Outreach Intervention Projects in Chicago. Participants were 570 young adults (18-25 years) who injected drugs in the previous 30 days. Heroin was the primary drug used in this sample. Past 12-month and lifetime substance use disorders and primary and substance-induced mental disorders were based on DSM-IV diagnostic criteria. Results Nearly all participants met the criteria for heroin dependence. Multiple substance use disorders were common; cannabis was the most common substance involved after heroin, followed by alcohol and cocaine. Major depression, alcohol dependence, antisocial personality disorder, and borderline personality disorder were highly prevalent. Other psychiatric disorders were observed at levels consistent with other young adult samples. Conclusions Young IDU experience major depression, alcohol dependence, anti-social personality disorder, and borderline personality disorder at high rates, and multiple substance use disorders are common. Anxiety disorders in this population appear to be similar in prevalence to young adults in general. PMID:22226707

Background Although previous studies have identified high levels of drug-related harm in Thailand, little is known about illicit drug overdose experiences among Thai drug users. We sought to investigate non-fatal overdose experiences and responses to overdose among a community-recruited sample of injection drug users (IDU) in Bangkok, Thailand. Methods Data for these analyses came from IDU participating in the Mit Sampan Community Research Project. The primary outcome of interest was a self-reported history of non-fatal overdose. We calculated the prevalence of past overdose and estimated its relationship with individual, drug-using, social, and structural factors using multivariate logistic regression. We also assessed the prevalence of ever witnessing an overdose and patterns of response to overdose. Results These analyses included 252 individuals; their median age was 36.5 years (IQR: 29.0 - 44.0) and 66 (26.2%) were female. A history of non-fatal overdose was reported by 75 (29.8%) participants. In a multivariate model, reporting a history of overdose was independently associated with a history of incarceration (Adjusted Odds Ratio [AOR] = 3.83, 95% Confidence Interval [CI]: 1.52 - 9.65, p = 0.004) and reporting use of drugs in combination (AOR = 2.48, 95% CI: 1.16 - 5.33, p = 0.019). A majority (67.9%) reported a history of witnessing an overdose; most reported responding to the most recent overdose using first aid (79.5%). Conclusions Experiencing and witnessing an overdose were common in this sample of Thai IDU. These findings support the need for increased provision of evidence-based responses to overdose including peer-based overdose interventions. PMID:20465842

Background Prescription opioids are the most frequently misused class of prescription drugs among young adults. Initiation into prescription opioid misuse is an important public health concern since opioids are increasingly associated with drug dependence and fatal overdose. Descriptive data about initiation into prescription opioid misuse among young injection drug users (IDUs) are scarce. Methods An exploratory qualitative study was undertaken to describe patterns of initiation into prescription opioid misuse among IDUs aged 16 to 25 years. Those young IDUs who had misused a prescription drug at least three times in the past three months were recruited during 2008 and 2009 in Los Angeles (n=25) and New York (n=25). Informed by an ethno-epidemiological approach, descriptive data from a semi-structured interview guide were analysed both quantitatively and qualitatively. Results Initiation into prescription opioid misuse was facilitated by easy access to opioids via participant’s own prescription, family, or friends, and occurred earlier than misuse of other illicit drugs, such as heroin. Nearly all transitioned into sniffing opioids, most injected opioids, and many initiated injection drug use with an opioid. Motives for transitions to sniffing and injecting opioids included obtaining a more potent high and/or substituting for heroin; access to multiple sources of opioids was common among those who progressed to sniffing and injecting opioids. Conclusion Prescription opioid misuse was a key feature of trajectories into injection drug use and/or heroin use among this sample of young IDUs. A new pattern of drug use may be emerging whereby IDUs initiate prescription opioid misuse before using heroin. PMID:21689917

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

A cross-sectional study to determine the prevalence of Human Immunodeficiency Virus (HIV) and HIV-associated risk behavior was conducted in February 1998 among 6,324 drug users in 26 drug rehabilitation centres in Malaysia. The majority of respondents were males (97.3%) and Malays (77.8%), administered drugs intravenously (64.6%) and of these 65.4% shared needles. About 78.1% had sexual exposure, of which 55.1% had sex with girl friends, 31.3% with prostitutes and 4.6% with male partners. The HIV prevalence rate in the group was 12.1% and significantly high among injecting drug users (IDU); those sharing needles; those who started addiction at a young age (10-15 years); those who had sexual exposures and had sex with prostitutes.

To assess the prevalence of improperly discarded syringes and to examine syringe disposal practices of injection drug users (IDUs) in San Francisco, we visually inspected 1000 random city blocks and conducted a survey of 602 IDUs. We found 20 syringes on the streets we inspected. IDUs reported disposing of 13% of syringes improperly. In multivariate analysis, obtaining syringes from syringe exchange programs was found to be protective against improper disposal, and injecting in public places was predictive of improper disposal. Few syringes posed a public health threat. PMID:20466956

Statins have been shown to be very effective and safe in numerous randomized clinical trials, and became the implacable first-line treatment against atherogenic dyslipidemia. However, even with optimal statin treatment, 60% to 80% of residual cardiovascular risk still exists. The patients with familial hypercholesterolemia which results in extremely high level of low density lipoprotein cholesterol (LDL-C) level and the patients who are intolerant or unresponsive to statins are the other hurdles of statin treatment. Recently, new classes of lipid-lowering drugs have been developed and some of them are available for the clinical practice. The pro-protein convertase subtilisin/kexintype 9 (PCSK9) inhibitor increases the expression of low density lipoprotein (LDL) receptor in hepatocytes by enhancing LDL receptor recycling. The microsomal triglyceride transport protein (MTP) inhibitor and antisense oligonucleotide against apolipoprotein B (ApoB) reduce the ApoB containing lipoprotein by blocking the hepatic very low density lipoprotein synthesis pathway. The apolipoprotein A1 (ApoA1) mimetics pursuing the beneficial effect of high density lipoprotein cholesterol and can reverse the course of atherosclerosis. ApoA1 mimetics had many controversial clinical data and need more validation in humans. The PCSK9 inhibitor recently showed promising results of significant LDL-C lowering in familial hypercholesterolemia (FH) patients from the long-term phase III trials. The MTP inhibitor and antisesnse oligonucleotide against ApoB were approved for the treatment of homozygous FH but still needs more consolidated evidences about hepatic safety such as hepatosteatosis. We would discuss the benefits and concerns of these new lipid-lowering drugs anticipating additional benefits beyond statin treatment. PMID:25922802

Background Hepatitis C virus is a persistent epidemiological problem, with an estimated 170 million individuals infected worldwide, and the leading cause of asymptomatic chronic infection, liver cirrhosis and hepatocellular carcinoma. Injection drug users (IDUs) have the highest seroprevalence as compared to chronic hemodialysis and transfusion patients, and this cohort remains the most under-studied high-risk group in North Africa to date. This study first sought to characterize the demographic, epidemiological, and genotypic profile of a total sample size of 211 chronically-infected IDUs living in the Tangier region of Northern Morocco, and secondly to contrast this to other chronically-infected patients, in order to uncover possible discrepancies. Results The general ‘profile’ of local IDUs marks a stark contrast to chronically-infected HCV Moroccan patients, other African countries, and neighboring European countries. The majority of Moroccan drug users were found to be middle-aged and celibate. A relatively high seroprevalence was found among drug users (60%), and this increased with age. The majority of drug users shared their needles and this hold implications for transmission, as seropositive status was significantly different between those users that shared vs. those that did not share their needles. In addition, IDUs exhibited genotypes 1a and 3a predominantly, as compared to the predominant 1b and 2a/2c genotypes found in chronically HCV-infected patients. The IDU genotypic profile closely matches the one in other European countries (Portugal, Spain, France, and Italy), which are invariably speculated as the potential source of currently-circulating genotypes in Moroccan IDUs. Conclusion These findings have implications for disease prevention, transmission and treatment, as this distinct IDU subgroup cannot be collectively pooled along with other HCV-positive high-risk groups. Local government, practitioners, and health institutions should take this

To test whether a four-session motivational intervention would reduce hepatitis C virus (HCV) seroincidence among injection and non-injection drug users compared to an assessment-only condition, we performed a randomized 24-month clinical trial. At baseline, 277 participants reported using heroin or cocaine at least three times weekly were HCV antibody negative, 65% were male and 46% were Caucasian and 39% reported having injected drugs. Of the 15 (5.4%) individuals who seroconverted, all reported injecting drugs either at baseline or during follow-up. Seroconversion rates did not differ significantly by treatment assignment (p =.79). The annual HCV incident rate was 8.20 (95% confidence interval [CI] = 4.76-14.13) for injectors and 0.74 (95% CI = 0.19-2.98) for non-injectors per 100 person-years. Significantly fewer participants in the intervention group initiated injection drug use behaviors (p =.009). This intervention was no more effective at reducing HCV seroconversion than assessment alone but did decrease injection initiation. PMID:20155608

An estimated 38.6 million persons globally are living with HIV, of whom over 1.1 million reside in Zambia. Of the 2 million cases in the US, 64% of new cases among women are among African Americans. Alcohol and drug use represents a significant risk factor for HIV transmission among both Zambians and African Americans. In addition, gender dynamics in both the US and Zambia promote transmission. This study examines two interventions targeting HIV risk behavior among HIV positive substance users, women in Miami, USA (the New Opportunities for Women (NOW) Project) and men in Lusaka, Zambia (the Partner Project). The study compares the efficacy of these two culturally tailored sexual behavior interventions provided in group and individual session formats. US and Zambian participants increased sexual barrier use and reduced substance-related sexual risk. Comparatively greater gains were made by higher risk Zambian males than US females in both group and individual conditions. Among lower risk participants, women in the group condition achieved and sustained the greatest comparative risk reductions. Results suggest that cost effective group HIV transmission risk reduction interventions for multiethnic individuals can be successfully implemented among both female and male drug and alcohol users in multinational settings.

Background Drug users in treatment or exiting treatment face many barriers to employment when entering the job market, such as low levels of education and technical skills, and low levels of interpersonal skills. As a result of these and other barriers, employment rates in these groups are generally low. Objective This article examines the existence and possible predictors of specific barriers to employment related to interpersonal and technical skills in a sample of participants enrolled in a therapeutic workplace intervention for substance abuse. Methods In Study I (N = 77), we characterized and examined predictors of participant scores on a staff-rated scale of interpersonal skills (Work Behavior Inventory). In Study II (N = 29), we examined whether participants had lower levels of computer knowledge than job seekers in the general population, and investigated possible predictors of computer knowledge in the sample. Results In general, participants in Study I displayed low levels of interpersonal skills, and participants in Study II scored lower on the computer knowledge test than job seekers in the general population. Older participants tended to have lower levels of interpersonal skills and lower levels of computer knowledge. Conclusions and Scientific Significance These results suggest that providers of workforce development services for drug users in treatment or exiting treatment should attend to these specific barriers to employment, which may also be more pronounced among older clients.

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

Several studies have attempted to understand the link among substance abuse, depression, and suicidal ideation (SI). Assessment of this link is important to develop specific interventions for persons in substance abuse treatment. This association was tested among 990 drug users in and out of treatment with significant criminal justice histories from two National Institute on Drug Abuse studies. The Diagnostic Interview Schedule and Substance Abuse Module assessed DSM-III-R depression, number of depression criteria met, antisocial personality disorder (ASPD), and substance use disorders. Compared with men, women were twice as likely to report depression (24% vs. 12%), whereas men were nearly twice as likely to report ASPD (42% vs. 24%). High rates of SI were found, with women more likely than men to report thoughts of death (50% vs. 31%), wanting to die (39% vs. 21%), thoughts of committing suicide (47% vs. 33%), or attempting suicide (33% vs. 11%); 63% of women and 47% of men reported at least one of these suicidal thoughts or behaviors. Male and female ideators were more likely than nonideators to report depressed mood and to meet criteria for depression, ASPD, and alcohol use disorders. Male ideators were more likely than male nonideators to meet criteria for cocaine use disorders. Using logistic regression, SI among men was predicted by alcohol use disorder (OR = 1.60), ASPD (OR = 1.59), and number of depression criteria (OR = 9.38 for five criteria). Among women, SI was predicted by older age, marital status, alcohol use disorder (OR = 2.77), and number of depression criteria (OR = 9.12 for five criteria). These original findings point out the need to discuss suicidal thoughts among depressed drug users for early treatment and prevention. PMID:15985836

We undertook qualitative interviews with 209 injecting drug users (primarily heroin) in three Russian cities: Moscow, Barnaul, and Volgograd. We explored drug injectors’ accounts of HIV and health risk. Policing practices and how these violate health and self emerged as a primary theme. Findings show that policing practices violate health and rights directly, but also indirectly, through the reproduction of social suffering. Extrajudicial policing practices produce fear and terror in the day-to-day lives of drug injectors, and ranged from the mundane (arrest without legal justification; the planting of evidence to expedite arrest or detainment; the extortion of money or drugs for police gain) to the extreme (physical violence as a means of facilitating ‘confession’ and as an act of ‘moral’ punishment without legal cause or rationale; the use of methods of ‘torture’; and rape). We identify the concept of police bespredel – living with the sense that there are ‘no limits’ to police power – as key to perpetuating fear and terror, internalized stigma, and a sense of fatalist risk acceptance. ‘Police besprediel’ is analyzed as a form of structural violence, contributing to ‘oppression illness’. Yet we also identify cases of resistance to such oppression, characterised by strategies to preserve dignity and hope. We identify hope for change as a resource of risk reduction as well as escape, if only temporarily, from the pervasiveness of social suffering. Future drug policies, and the state responses they sponsor, should set out to promote public health while protecting human rights, hope and human dignity. PMID:20397872

Introduction Drug dealing among drug users has been associated with elevated risk-taking and negative health outcomes. However, little is known about the cessation of drug dealing among this population. Methods We assessed time to cessation of drug dealing using Cox regression. We also used generalized estimation equation (GEE) analysis and chi-square analysis to examine factors associated with willingness to cease drug dealing. Results In total, 868 participants reported drug dealing between November 2005 and March 2009. Among 381 participants dealing drugs at baseline, 194 (51%) ceased dealing. Incidence of dealing cessation was positively associated with spending less than $50 per day on drugs (Adjusted Hazard Ratio [AHR] = 1.88, 95% Confidence Interval [CI]: 1.14 - 3.10) and negatively associated with buying drugs from the same source (AHR = 0.60, 95% CI: 0.37 - 0.98). In a GEE analysis, willingness to cease dealing was positively associated with older age (Adjusted Odds Ratio [AOR] = 1.02, 95% CI: 1.01 - 1.03), crack use (AOR = 2.00, 95% CI: 1.44 - 2.79), public injecting (AOR = 1.95, 95% CI: 1.55 - 2.43), and reporting that police presence affects drug purchases (AOR = 1.53, 95% CI: 1.22 - 1.91), and negatively associated with crystal methamphetamine injection (AOR = 0.62, 95% CI: 0.47 - 0.83). Discussion Intensity of drug use and acquisition method were predictive of dealing cessation. Willingness to cease dealing was associated with a range of risky drug-related activities. Interventions to reduce drug dealing should be conceived in tandem with addiction treatment strategies. PMID:21664770

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

Cryptosporidiosis affects humans of all ages, particularly malnourished children and those with compromised immune systems such as HIV/AIDS. This study investigated the therapeutic effects of acetylspiramycin and garlicin on Cryptosporidium infection in institutionalized male drug users receiving rehabilitative treatment. Examination of stool specimens from 903 drug users via modified acid-fast bacilli staining resulted in 172 positive cases. Among them 151 subjects consented to participate in a randomized trial of acetylspiramycin and garlicin in four groups: acetylspiramycin plus garlicin, acetylspiramycin only, garlicin only, and placebo control. The cryptosporidiosis rate was higher in younger subjects with longer drug use history than subjects who are older with shorter history of drug use. After two segments of treatments, 76.2% of the cases achieved negative test results, with the four groups achieving the rates of 92.1%, 76.7%, 72.2%, and 61.8%, respectively (χ2 = 9.517, P = 0.023). These results indicate clinical potential of garlicin in conjunction with acetylspiramycin in treating cryptosporidiosis. PMID:27120065

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.

This study examined the prevalence and correlates of HIV risk behaviors among 1,153 current drug users in China. Chi-squared tests of differences were used to test if drug users differed from non-users; logistic regression was used to identify behavior-specific risk factors. Results indicate that 60% of drug users injected drugs and more than one third shared needles. Compared to non-users, drug users had higher rates of risky sexual behavior and HIV/STDs. Among drug users, ethnic minorities and migrants were most vulnerable to unprotected casual sex and needle sharing. Drug users who experienced social isolation were associated with lower odds of risk behaviors; those who had experiences of anti-social behaviors and commercial sex, poor HIV knowledge, and perceived greater vulnerability were more prone to unprotected casual sex and needle sharing. Additional correlates of unprotected casual sex included being single, depression, and taking drugs/alcohol during sex. Additional risk factors of needle sharing included education and initiated drug use at younger ages. It is imperative that HIV interventions in China target drug users and address behavior-specific risk factors. PMID:16323036

Infective endocarditis is a common complication among injecting drug users. Disease risk among these patients is increased by the spread of HIV infection. In the following article, we discuss the exceptional clinical presentation of a 28-year-old patient who used intravenous drugs (heroin) for 10 years, had been infected with HIV for seven years and as a complication had developed Staphylococcus aureus infective endocarditis. The patient came to the hospital in serious condition, complaining of bodily pain, swelling of the legs and general weakness. During hospitalization, besides infective endocarditis, she was also diagnosed with anemia, toxic hepatitis, renal failure, ascites, sepsis, and pneumonia. A completely disrupted tricuspid valve, damaged aortic valve, and fibrosis of the mitral valve were detected. Echocardiographic and radiologic data showed that the patient's condition continued to deteriorate day by day, with significant progression of heart failure, ejection fraction decreasing from 45% to 10%, and development of myocarditis, hydrothorax and pericarditis. However, this progressive worsening of the patient's condition ceased when vancomycin was administered. To the authors' knowledge, this is the first such case described in the literature in which significant improvement was observed despite the patient's complex condition with associated complications.

We characterized hepatitis C virus (HCV) treatment knowledge, experience and barriers in a cohort of community-based injection drug users (IDUs) in Baltimore, MD. In 2005, a questionnaire on HCV treatment knowledge, experience and barriers was administered to HCV-infected IDUs. Self-reported treatment was confirmed from medical records. Of 597 participants, 71% were male, 95% African-American, 31% HIV co-infected and 94% were infected with HCV genotype 1; 70% were aware that treatment was available, but only 22% understood that HCV could be cured. Of 418 who had heard of treatment, 86 (21%) reported an evaluation by a provider that included a discussion of treatment of whom 30 refused treatment, 20 deferred and 36 reported initiating treatment (6% overall). The most common reasons for refusal were related to treatment-related perceptions and a low perceived need of treatment. Compared to those who had discussed treatment with their provider, those who had not were more likely to be injecting drugs, less likely to have health insurance, and less knowledgeable about treatment. Low HCV treatment effectiveness was observed in this IDU population. Comprehensive integrated care strategies that incorporate education, case-management and peer support are needed to improve care and treatment of HCV-infected IDUs. PMID:18165889

The internment process in therapeutic communities (TC) involves a multiplicity of therapeutic practices and strategies geared to abstinence from drug usage. According to the specialists' own regulations and explicit objectives, the residents must not only abandon the consumption of substances but also adopt new practices, attitudes, emotions and significances through the use of therapeutic techniques that allow them to adapt to the structure of the organization that these institutions impose. Based on the results of the ethnographic survey carried out between 2009 and 2010 in three TCs of the metropolitan area of Buenos Aires, Argentina, the scope of this article is to analyze from a sociological and anthropological standpoint the "therapeutic tools" that comprise the treatment, the subject models that underlie these tools, the consequences that they may produce and their participation in the subjectivity production processes. For this purpose, we focus on analysis of "confrontation" as a privileged and omnipresent strategy of subjectivation in these therapeutic contexts, in order to reveal the epistemological, economic, political and ethical dimensions in the de-subjectivation process of the institutionalized drug user.

Background: Drug injection is one of the most prominent risk factors for transmission of viral hepatitis. Prevalence of hepatitis B virus (HBV) is generally higher in prisoners compared with the general population. The object of this study was to assess the markers of HBV and related risk factors among intravenous drug users (IVDU) in prisoners. Materials and Methods: Through a cross-sectional study in 2012 HBV infection and its risk factors were assessed in prisoners with a history of intravenous drug use in Isfahan, Iran. A checklist was fulfilled for each participant and 5 ml blood was taken from each subject. Sera were analyzed for markers of the hepatitis B: Hepatitis B virus surface antigen (HBsAg), antibody to hepatitis B virus surface antigen (HBsAb) and hepatitis B virus core antibody (HBcAb) by ELISA. We used Chi-square test and logistic regression model to analyze data and P < 0.05 was considered to be significant. Results: All of the studied participants (n = 970) were men. The mean ± standard deviation of the age of the subjects was 32.61 ± 8.1 years and the majority of them had less than high school education. More than 40% of these men had a history of injection drug inside prison and 2.27% of them self-reported history of HBV infection. Of the 970 IVDU, 32 (3.3%) were positive for HBsAg. Among HBsAg + subjects, 23 (71.88%) were HBcAb+. 120 (12.37%) were found positive for isolated HBsAb, 45 (4.64%) for isolated HBcAb and 67 (6.9%) for both HBsAb and HBcAb. History of sharing needle (odds ratio: 2.25, 95% confidence interval: 1.09-4.65) had a significant association with HBsAg positivity. Conclusion: The results suggest that history of sharing needle had a significant association with HBsAg positivity. It seems that educational programs for injecting drug related behaviors, especially syringe sharing, are needed for IVDU. PMID:25002887

Background Ketamine is a dissociative anesthetic that became increasing popular in the club and rave scene in the 1980s and 1990s. Reports surfaced in the late 1990s indicating that ketamine was being injected in several U.S. cities by young injection drug users (IDUs). Since all studies on ketamine injection were cross-sectional, a longitudinal study was undertaken in 2005 to determine: characteristics of young IDUs who continue to inject ketamine; frequency of ketamine injection over an extended time period; risks associated with ongoing ketamine injection; and environmental factors that impact patterns of ketamine use. Methods Young IDUs aged 16 to 29 with a history of injecting ketamine (n=101) were recruited from public locations in Los Angeles and followed during a two-year longitudinal study. A semi-structured instrument captured quantitative and qualitative data on patterns of ketamine injection and other drug use. A statistical model sorted IDUs who completed three or more interviews (n=66) into three groups based upon patterns of ketamine injection at baseline and follow-up. Qualitative analysis focused on detailed case studies within each group. Results IDUs recruited at baseline were typically in their early 20s, male, heterosexual, white, and homeless. Longitudinal injection trajectories included: “Moderates,” who injected ketamine several times per year (n=5); “Occasionals,” who injected ketamine approximately once per year (n=21); and “Abstainers,” who did not inject any ketamine during follow-up (n=40). Findings suggest that ketamine is infrequently injected compared to other drugs such as heroin, cocaine, and methamphetamine. Most IDUs who begin injecting ketamine will stop or curb use due to: negative or ambivalent experiences associated with ketamine; an inability to find the drug due to declining supply; or maturing out of injecting drugs more generally. Conclusion Reducing ketamine injection among young IDUs may best be accomplished

Background There is evidence of a high prevalence of prescription opioid (PO) and crack use among street drug users in Toronto. The purpose of this qualitative study was to describe drug use behaviours and preferences as well as the social and environmental context surrounding the use of these drugs among young and old street-based drug injection drug users (IDUs). Methods In-depth interviews were conducted with 25 PO injectors. Topics covered included drug use history, types of drugs used, how drugs were purchased and transitions to PO use. Interviews were taped and transcribed. Content analysis was conducted to identify themes. Results Five prominent themes emerged from the interviews: 1) Combination of crack and prescription opioids, 2) First injection experience and transition to prescription opioids, 3) Drug preferences and availability, 4) Housing and income and 5) Obtaining drugs. There was consensus that OxyContin and crack were the most commonly available drugs on the streets of Toronto. Drug use preferences and behaviours were influenced by the availability of drugs, the desired effect, ease of administration and expectations around the purity of the drugs. Distinct experiences were observed among younger users as compared to older users. In particular, the initiation of injection drug use and experimentation with POs among younger users was influenced by their experiences on the street, their peers and general curiosity. Conclusion Given the current profile of street-based drug market in Toronto and the emergence of crack and POs as two predominant illicit drug groups, understanding drug use patterns and socio-economic factors among younger and older users in this population has important implications for preventive and therapeutic interventions.

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 A large portion of violence associated with drug use is due to drug dealing. These analyses sought to examine injection drug users' attitudes and experiences of drug dealer violence. Methods The current study used the 18-month follow up data of STEP into Action (STEP) study, an HIV prevention intervention among drug injectors and their risk network members conducted in Baltimore, Maryland. Four scales assessed acceptability of drug dealer violence, willingness to talk to drug users about avoiding drug dealer violence, social norms about reporting drug dealer violence, and intentions to report drug dealer violence to the police. Results Many (44%) of the 373 participants reported witnessing drug dealers' acts of violence within the prior 6 months. Although the majority of participants disagreed with statements on the acceptability of dealers using violence, only a minority indicated that they would call the police if they observed dealer violence. Most participants indicated that they would be interested in talking to drug users about how to avoid violent dealers. Males were more likely to report that violence was acceptable, whereas African Americans were less likely to condone violence. Those who were homeless and had higher incomes were more likely to report witnessing drug dealer violence. Conclusions These results suggest that it may be feasible to train current and former drug users and their risk network members in methods to promote violence reduction among drug dealers.

Background Among male injection drug users (IDUs) in Tijuana, Mexico, U.S. deportation is associated with HIV transmission. Changing drug use behaviors following deportation, including the use of new drugs, may increase HIV risk but are understudied. We identify correlates of trying new drugs following male IDUs’ most recent U.S. deportation to Mexico. Methods In 2010, we recruited 328 deported male IDUs in Tijuana, Mexico. Questionnaires collected retrospective data on drug use and other HIV risk behaviors throughout migratory events. Logistic regression identified correlates of trying new drugs/combinations following their most recent deportations. Informed consent was obtained from all participants. Results Nearly one in six men (n=52, 16%) tried new drugs following their most recent deportation, including heroin (n=31), methamphetamine (n=5), and heroin/methamphetamine combined (n=17). Trying new drugs following deportation was independently associated with U.S. incarceration (adjusted odds ratio [AOR]= 3.96; 95% confidence interval [C.I.] 1.78, 8.84), increasing numbers of U.S. deportations (AOR=1.11 per deportation; C.I. 1.03, 1.20), feeling sad following deportation (AOR 2.69; C.I. 1.41, 5.14), and perceiving that one’s current lifestyle increases HIV/AIDS risk (AOR 3.91; C.I. 2.05, 7.44). Conclusions Trying new drugs following U.S. deportation may be related to the unique contexts and stressors experienced by drug-abusing migrants as they attempt to reestablish their lives in Mexico. Findings imply an unmet need for health and social programs to alleviate pre-and post-deportation stressors faced by undocumented and return migrants in the U.S.-Mexico context. PMID:21835559

In 1992, New York State Department of Health regulations provided for fully legal syringe exchange programmes in the state. The policies and procedures mandated that: 'Each program must seek to recruit ... for inclusion on its advisory board ... program participants ... Programs are also urged to establish other advisory bodies, such as Users' Advisory Boards made up of program participants, to provide input and guidance on program policies and operations.' The inclusion of drug users as official advisors to the legal programmes was seen as a method for incorporating the views of the consumers of the service in operational decisions. The 1992 regulations implied a new public image for users of illicit psychoactive drugs: active drug users were seen to be capable not only of self-protective actions (such as avoiding HIV infection), but also of serving as competent collaborators in programmes to preserve the public health. This development has important implications with regard to the evolution of official drug policy, since it will be difficult in future to treat IDUs simply as the passive objects of state intervention. Whether as individuals or representatives of a wider population of illicit drug users, they have acquired a legitimacy and sense of personal worth which would have been unthinkable in previous periods.

Nowadays a substantial armamentarium of antiepileptic drugs (AEDs) is available, including drugs with different mechanisms of action, pharmacokinetics, efficacy and tolerability; therefore the choice for the right treatment is often challenging. The specific characteristic of the drug, the epileptic syndrome, seizure types and the patient's features need to be taken into consideration driving the choice through available evidence-based studies, which are often lacking for older AEDs. Besides, study conditions in registered clinical trials (RCTs) are quite different from daily clinical practice, which is more complex and various. When dealing with first diagnosed epilepsy, monotherapy is widely accepted as the gold standard option. Likewise, alternative monotherapy should be considered when the first drug treatment fails. However, the association of different AEDs in polytherapy is a common practice. The choice of AEDs used in association is often based on clinical experience or anecdotal observations or small clinical studies. Polytherapy should be as "rational" as possible and consider the mechanism of action, the pharmacokinetic characteristics and the safety of each drug. When dealing with drug resistant patients, clinicians should never give up and consider the use of AEDs acting on new targets. An attempt to come back to a monotherapy or simpler therapeutic regimen should be pursued even in patients who were previously drug resistant. This review will focus on the strategies to treat epilepsy by choosing among 25 available drugs. PMID:26995307
Drug use is a complex behavior with multidimensional determinants, including social, psychological, cultural, economic, and biological factors. Blood borne viral infections including hepatitis C virus are transmitted when an uninfected intravenous drug user (IVDU) uses injection equipment, especially syringes, that have previously been used by an infected person. The transmission can also result from sharing other injection equipment such as 'cookers' and 'cottons'. Recent studies have shown that the prevalence and incidence of drug abuse have declined substantially since the introduction of needle exchange. Infection with hepatitis C may spontaneously resolve during the acute stage and never progress to chronic infection, or the infection may become chronic without medical complications, or the infection may become chronic with progressive medical complications. Regular testing for infection is an important strategy for secondary prevention of chronic hepatitis C infection. Care for hepatitis C is a vital component of a comprehensive health program for persons using illicit drugs. Such care includes screening for transmission risk behavior, prevention counseling and education, testing for HCV antibody and RNA. IDUs found to have chronic HCV infection should be assessed for the presence and degree of liver disease and evaluated for treatment for HCV Hepatitis C care also requires providing access to treatment for substance use and abuse. Therapy with opioid agonists, including methadone maintenance treatment, has been shown to diminish and often eliminate opioid use and reduce transmission of infection. Approval of buprenorphine makes office-based pharmacotherapy for opioid addiction possible. When considering treatment for hepatitis C, particular attention must be paid to mental health conditions. As a group, IDUs exhibit higher rates of comorbid psychiatric disorders than the general population. IFN-based regimens for hepatitis C are often complicated by

This study assesses relationships between drug administration routes and HIV serostatus, drug-use and sexual behaviors among current injecting drug users (IDUs) in Tallinn, Estonia. We recruited 350 IDUs for a cross-sectional risk behavior survey. Adjusted odds ratios (AORs) were calculated to explore injection risk behavior, sexual behavior and HIV serostatus associated with multiple route use. Focus groups explored reasons why injectors might use non-injecting routes of administration. Those reporting multiple drug administration routes were less likely to be HIV seropositive (AOR 0.49; 95%CI 0.25-0.97), had almost twice the odds of having more than one sexual partner (AOR 1.90; 95%CI 1.01-3.60) and of reporting having sexually transmitted diseases (AOR 2.38; 95%CI 1.02-5.59). IDUs who engage in non-injecting drug use may be reducing their risk of acquiring HIV though sharing injection equipment, but if infected may be a critical group for sexual transmission of HIV to people who do not inject drugs.

Ibogaine is an alkaloid purported to be an effective drug dependence treatment. However, its efficacy has been hard to evaluate, partly because it is illegal in some countries. In such places, treatments are conducted in underground settings where fatalities have occurred. In Brazil ibogaine is unregulated and a combined approach of psychotherapy and ibogaine is being practiced to treat addiction. To evaluate the safety and efficacy of ibogaine, we conducted a retrospective analysis of data from 75 previous alcohol, cannabis, cocaine and crack users (72% poly-drug users). We observed no serious adverse reactions or fatalities, and found 61% of participants abstinent. Participants treated with ibogaine only once reported abstinence for a median of 5.5 months and those treated multiple times for a median of 8.4 months. This increase was statistically significant (p < 0.001), and both single or multiple treatments led to longer abstinence periods than before the first ibogaine session (p < 0.001). These results suggest that the use of ibogaine supervised by a physician and accompanied by psychotherapy can facilitate prolonged periods of abstinence, without the occurrence of fatalities or complications. These results suggest that ibogaine can be a safe and effective treatment for dependence on stimulant and other non-opiate drugs. PMID:25271214

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. PMID:24126204

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

OBJECTIVE To estimate rates of non-adherence to telemedicine strategies aimed at treating drug addiction. METHODS A systematic review was conducted of randomized controlled trials investigating different telemedicine treatment methods for drug addiction. The following databases were consulted between May 18, 2012 and June 21, 2012: PubMed, PsycINFO, SciELO, Wiley (The Cochrane Library), Embase, Clinical trials and Google Scholar. The Grading of Recommendations Assessment, Development and Evaluation was used to evaluate the quality of the studies. The criteria evaluated were: appropriate sequence of data generation, allocation concealment, blinding, description of losses and exclusions and analysis by intention to treat. There were 274 studies selected, of which 20 were analyzed. RESULTS Non-adherence rates varied between 15.0% and 70.0%. The interventions evaluated were of at least three months duration and, although they all used telemedicine as support, treatment methods differed. Regarding the quality of the studies, the values also varied from very poor to high quality. High quality studies showed better adherence rates, as did those using more than one technique of intervention and a limited treatment time. Mono-user studies showed better adherence rates than poly-user studies. CONCLUSIONS Rates of non-adherence to treatment involving telemedicine on the part of users of psycho-active substances differed considerably, depending on the country, the intervention method, follow-up time and substances used. Using more than one technique of intervention, short duration of treatment and the type of substance used by patients appear to facilitate adherence. PMID:25119947

Alcohol and drug dependence are serious public health problems worldwide. The prevalence of alcohol and drug dependence in the United States and other parts of the world is significant. Given the limitations in the efficacy of current pharmacotherapies to treat these disorders, research in developing alternative pharmacotherapies continues. Preclinical and clinical evidence thus far has indicated that brain nicotinic acetylcholine receptors (nAChRs) are important pharmacological targets for the development of medications to treat alcohol and drug dependence. The nAChRs are a super family of ligand gated ion channels, and are expressed throughout the brain with twelve neuronal nAChR subunits (α2–α10 and β2–β4) identified. Here, we review preclinical and clinical evidence involving a number of nAChR ligands that target different nAChR subtypes in alcohol and nicotine addiction. The important ligands include cytisine, lobeline, mecamylamine, varenicline, sazetidine A and others that target α4β2* nAChR subtypes as small molecule modulators of the brain nicotinic cholinergic system are also discussed. Taken together, both preclinical and clinical data exist that support nAChR–based ligands as promising therapeutic agents for the treatment of alcohol and drug dependence. PMID:25642160

Injection drug use has fueled the epidemic of human immunodeficiency virus (HIV) and hepatitis C virus (HCV) coinfection in the United States. Nevertheless, drug dependence is among the main reasons that coinfected persons are not being treated for HCV infection. This report describes the development and progress of an HIV clinic program (funded by the Ryan White Comprehensive AIDS Resources Emergency Act) to deliver care for HCV infection to HIV-seropositive injection drug users. To optimize safety and adherence, pegylated interferon is directly administered to patients in the context of integrated addiction, psychiatric, and HIV and HCV therapy. Ribavirin is packed weekly in pill boxes for patients to take at home. Thus far, adherence to weekly visits for treatment with interferon has been 99%. No one has had to stop treatment for HCV infection because of ongoing drug use, addiction relapse or exacerbation, or psychiatric complications. Presented here is a work in progress, rather than a finished research project or definitive model of care. PMID:15768348

Intravenous (i.v.) drug users are a key factor in the transmission of human immunodeficiency virus (HIV) infection, yet epidemiologic information about this population, especially those with acquired immunodeficiency syndrome, is scarce. The demographic characteristics, drug use behavior, and sexual practices of i.v. drug users who developed AIDS were prospectively studied at the Montefiore Medical Center from October 1984 to February 1988. The early wave of i.v. drug users with AIDS was characterized by poverty, minority overrepresentation (more than 80 percent were black or Hispanic), and initiation of i.v. drug use at an early age (median age 19 years). Injection of drugs and sharing of needles was frequent. Most had used so-called shooting galleries, but only for a minority of injection episodes. Heroin or cocaine use was almost universal, nearly always accompanied by abuse of another substance, usually alcohol or marijuana. Fewer than a third had ever participated in a methadone maintenance program, but more than 40 percent had been in prison since 1978. All patients had been sexually active, often with partners who were not i.v. drug users. The research suggests a complex interaction existing between high-risk demographic characteristics, drug use practice, and certain types of sexual behavior, all of which contributed to the early spread of HIV infection in this population. Efforts that are directed toward interrupting i.v. drug user-related transmission of HIV need to include consideration of these characteristics. PMID:1899944

A color, sound film depicting five young people discussing drug use was used to test participants in three workshops and two regular drug courses. Results suggest that initial exposure to drug training increases acceptance of drug use, perhaps by dispelling fearsome myths, but extended training reinstates rejection. (Author)
Background Karachi is the largest metropolis of Pakistan and its economic hub attracting domestic migrants for economic opportunities. It is also the epicenter of HIV epidemic in the country. Since 2004, one pilot study and four behavioral and biological surveillance rounds have been conducted in Karachi. In addition many student research projects have also focused on key risk groups including injection drug users (IDUs). As a result of this extra ordinary exposure of same kind of questions, IDUs know how to respond to high value questions related to sharing of needles or unsafe sexual practices. The purpose of the study was to explore the element of research fatigue among IDUs in Karachi, Pakistan. Methods The study was conducted on 32 spots in Karachi, selected on the basis of estimate of IDUs at each spot. A trained field worker (recovered IDU) visited each spot; observed sharing behavior of IDUs and asked questions related to practices in January 2009. Verbal consent was obtained from each respondent before asking questions. Results On average 14 IDUs were present at each spot and out of 32 selected spots, 81% were active while more than two groups were present at 69% spots. In each group three to four IDUs were present and everyone in the group was sharing. One dose of injecting narcotics was observed. Sharing of syringes, needles and distilled water was observed at 63% spots while professional injector/street doctor was present at 60% spots. Conclusion There is a need to check internal consistency in surveillance research. It is highly likely that IDUs and other risk groups know how to respond to key questions but their responses do not match with the practices. PMID:23758666

We analyzed data from 6341 injection drug users (IDUs) entering detoxification or methadone maintenance treatment in New York City between 1990 and 2004 to test the hypothesis that alcohol use and intoxication is associated with increased HIV sexual risk behaviors. Two types of associations were assessed: (1) a global association (i.e., the relationship between HIV sexual risk behaviors during the 6 months prior to the interview and at-risk drinking in that period, defined as more than 14 drinks per week for males or 7 drinks per week for females), and (2) an event-specific association (i.e., the relationship between HIV sexual risk behaviors during the most recent sex episode and alcohol intoxication during that episode). Sexual risk behaviors included multiple sex partners and engaging in unprotected sex. After adjusting for the effects of other variables, at-risk-drinkers were more likely to report multiple sex partners and engaging in unprotected sex with casual sex partners (both global associations). IDUs who reported both they and their casual partners were intoxicated during the most recent sex episode were more likely to engage in unprotected sex (an event-specific association). We also observed two significant interactions. Among IDUs who did not inject cocaine, moderate-drinkers were more likely to report multiple partners. Among self-reported HIV seropositive IDUs, when both primary partners were intoxicated during the most recent sex episode they were more likely to engage in unprotected sex. These observations indicate both global and event-specific associations of alcohol and HIV sexual-risk behaviors. PMID:18242009

OBJECTIVES: This article reviews the evidence on the adverse health consequences of low socioeconomic status, homelessness, and incarceration among drug users. OBSERVATIONS: Social and economic factors shape risk behavior and the health of drug users. They affect health indirectly by shaping individual drug-use behavior; they affect health directly by affecting the availability of resources, access to social welfare systems, marginalization, and compliance with medication. Minority groups experience a disproportionately high level of the social factors that adversely affect health, factors that contribute to disparities in health among drug users. CONCLUSION: Public health interventions aimed at improving the health of drug users must address the social factors that accompany and exacerbate the health consequences of illicit drug use.

There is currently no effective treatment for the Ebola virus (EBOV) thus far. Most drugs and vaccines developed to date have not yet been approved for human trials. Two FDA-approved c-AbI1 tyrosine kinase inhibitors Gleevec and Tasigna block the release of viral particles; however, their clinical dosages are much lower than the dosages required for effective EBOV suppression. An α-1,2-glucosidase inhibitor Miglustat has been shown to inhibit EBOV particle assembly and secretion. Additionally, the estrogen receptor modulators Clomiphene and Toremifene prevent membrane fusion of EBOV and 50-90% of treated mice survived after Clomiphene/Toremifene treatments. However, the uptake efficiency of Clomiphene by oral administration is very low. Thus, I propose a hypothetical treatment protocol to treat Ebola virus infection with a cumulative use of both Miglustat and Toremifene to inhibit the virus effectively and synergistically. EBOV infection induces massive apoptosis of peripheral lymphocytes. Also, cytolysis of endothelial cells triggers disseminated intravascular coagulation (DIC) and subsequent multiple organ failures. Therefore, blood transfusions and active treatments with FDA-approved drugs to treat DIC are also recommended. PMID:25984303

Antiplatelet drugs are widely used for the prevention of cardiovascular disease and cerebral vascular disorders. Although there have been several studies on gastroduodenal mucosal injury with gastrointestinal (GI) symptoms such as GI bleeding, in antiplatelet drug users (including low-dose aspirin (LDA)), there have been few reports on the association between antiplatelet drug use and gastroduodenal mucosal injury in asymptomatic antiplatelet drug users. This study was a cross-sectional study elucidating the association between antiplatelet drug use and gastroduodenal mucosal injury in asymptomatic antiplatelet drug users.Subjects were 186 asymptomatic Japanese antiplatelet drug users who underwent a regular health checkup. Subjects were divided into those with and without gastroduodenal mucosal injury endoscopically, and the association between gastroduodenal mucosal injury and other data in asymptomatic antiplatelet drug users was investigated.The prevalence of males and drinkers were significantly higher in subjects with gastroduodenal mucosal injury than in those without. In addition, the prevalence of proton pump inhibitor (PPI) users was significantly lower in subjects with gastroduodenal mucosal injury than in subjects without gastroduodenal mucosal injury. Logistic regression analysis showed PPI (odds ratios: 0.116; 95% confidence intervals: 0.021-0.638; P < 0.05) was a significant predictor of a decreased prevalence of gastroduodenal mucosal injury and closed-type (C-type) atrophy (3.172; 1.322-7.609; P < 0.01) was a significant predictor of an increased prevalence of severe gastroduodenal mucosal injury in asymptomatic antiplatelet drug users.Gender and lifestyle, such as drinking, may have an impact on risk of gastroduodenal mucosal injury in asymptomatic subjects taking antiplatelet drugs. Although PPI is a significant predictor of a decreased prevalence of gastroduodenal mucosal injury, including in asymptomatic antiplatelet drug users, status of

Early onset of alcohol, marijuana, and cigarette use is an indicator of later substance use problems in adulthood such as alcohol or other drug dependence. This paper seeks to address the association between early onset alcohol, marijuana, cigarette, and polysubstance use with injection drug use among recent illicit drug users. The current study used baseline data from the Baltimore site of the NEURO-HIV Epidemiologic Study, an investigation of neuropsychological and social-behavioral risk factors of HIV, hepatitis A, hepatitis B, and Hepatitis C among both injection and non-injection drug users in Baltimore Maryland. The present study used a subset (N = 651) of the larger parent study that identified as White or Black, and reported any drug use in the past 6 months. In the full sample slightly more than half (52.5%) of study participants were IDUs. IDUs differed from non-IDUs on age of initiation for cigarettes, marijuana, and alcohol, with IDUs initiating the use of all three substances significantly earlier than non-IDUs. IDUs also had significantly greater proportions of early onset of alcohol (χ2 = 19.71, p < .01), cigarette (χ2 = 11.05, p < .01), marijuana (χ2 = 10.83, p < .01), and polysubstance use (χ2 = 23.48, p < .01) than non-IDUs. After adjusting for age, gender, and race/ethnicity, only participants identified as early onset alcohol users (AOR = 1.47, 95% CI: 1.00-2.18) and early onset polysubstance users (AOR = 1.62, 95% CI: 1.10-2.38) were more likely to have IDU status than those who reported initiating substance use later. IDU status was then stratified by race/ethnicity. After controlling for age and gender, only early polysubstance use was a significant predictor of IDU status for Whites (AOR = 2.06, 95% CI: 1.07-3.93). Consistent with literature on early substance initiation and later illicit substance use, early onset alcohol and polysubstance use is an important risk factor for IDU in adulthood. PMID:22172686

Background The HIV epidemic in Russia has been driven by the unsafe injection of drugs, predominantly heroin and the ephedrine derived psychostimulants. Understanding differences in HIV risk behaviors among injectors associated with different substances has important implications for prevention programs. Methods We examined behaviors associated with HIV risk among 900 IDUs who inject heroin, psychostimulants, or multiple substances in 2002. Study participants completed screening questionnaires that provided data on sociodemographics, drug use, place of residence and injection- and sex-related HIV risk behaviors. HIV testing was performed and prevalence was modeled using general estimating equation (GEE) analysis. Individuals were clustered by neighborhood and disaggregated into three drug use categories: Heroin Only Users, Stimulant Only Users, and Mixed Drug Users. Results Among Heroin Only Users, younger age, front/backloading of syringes, sharing cotton and cookers were all significant predictors of HIV infection. In contrast, sharing needles and rinse water were significant among the Stimulant Only Users. The Mixed Drug Use group was similar to the Heroin Only Users with age, front/back loading, and sharing cotton significantly associated with HIV infection. These differences became apparent only when neighborhood of residence was included in models run using GEE. Conclusion The type of drug injected was associated with distinct behavioral risks. Risks specific to Stimulant Only Users appeared related to direct syringe sharing. The risks specific to the other two groups are common to the process of sharing drugs in preparation to injecting. Across the board, IDUs could profit from prevention education that emphasizes both access to clean syringes and preparing and apportioning drug with these clean syringes. However, attention to neighborhood differences might improve the intervention impact for injectors who favor different drugs. PMID:19646255

Tuberculosis (TB) is still one of the most difficult infectious diseases to treat, and the second most frequent cause of death due to infectious disease throughout the world. The number of cases of multidrug-resistant (MDR-TB) and extensively drug-resistant TB (XDR-TB), which are characterised by high mortality rates, is increasing. The therapeutic management of children with MDR- and XDR-TB is complicated by a lack of knowledge, and the fact that many potentially useful drugs are not registered for pediatric use and there are no formulations suitable for children in the first years of life. Furthermore, most of the available drugs are burdened by major adverse events that need to be taken into account, particularly in the case of prolonged therapy. This document describes the recommendations of a group of scientific societies on the therapeutic approach to pediatric MDR- and XDR-TB. On the basis of a systematic literature review and their personal clinical experience, the experts recommend that children with active TB caused by a drug-resistant strain of Mycobacterium tuberculosis should always be referred to a specialised centre because of the complexity of patient management, the paucity of pediatric data, and the high incidence of adverse events due to second-line anti-TB treatment.

Drug use is considered a main contributing factor to crime and violence. This research examined the evidence regarding the relationship between drug abuse and the occurrence of intimate partner violence. Current drug using men were assessed on aggression related personality variables, their drug use, and the occurrence of violence in their close relationships. A latent aggression factor and recent amphetamine use were the only variables found to be significantly associated with violence. No other drug use variables were found to be associated with violence by the participant and the overall drug use factor was not found to be associated with violence or aggressive personality. The widely accepted notion that increased substance use directly leads to increases in violent behavior was only partially supported, at least within this drug using population. The assessment of aggressive personality, rather than of drug use, is suggested for correctional as well as clinical settings in which drug users are prevalent when determining susceptibility to violence.

The main objective of this paper is to explore poly-drug use among young adult ecstasy users. This phenomenon of using multiple substances within a specific time period is multi-faceted. In this paper, we focus on the various patterns of poly-drug use and the reasons for combining multiple drugs among ecstasy users. Using a mixed-methods design, we conducted interviews with young adults who used ecstasy and other licit and illicit drugs in the past 90 days. Based on the qualitative analyses, we define three distinct types of poly-drug experiences: separate, synergistic, and indiscriminate use. While separate and synergistic poly-drug use tended to be intentional, indiscriminate poly-drug use often was unintentional. These findings show the importance of recognizing poly-drug use as a common phenomenon. The findings presented here suggest areas for further research aimed at identifying risk and protective behaviors and risk reduction strategies. PMID:23913981

Although aminoglycosides antibiotics are used in children and adult commonly, they have serious side effects such as nephrotoxicity and ototoxicity. In clinical practice, for renal function, the levels of serum creatinine and blood urea nitrogen routinely are measured. Since these parameters have limitations such as unreliability, insensitivity, and nonspecificity, the rapid assessment of renal function based on these patients is very important. Increase in N-acetyl-beta-D-glucosaminidase (NAG), a hydrolytic lysosomal enzyme, suggests proximal tubular cell damage. In this study, 32 children aged 2 months through 2 years, treated with gentamicin and amikacin for suspected infections at the pediatric ward of Alborz hospital from September 2006 to February 2007, were enrolled. Serum and fresh urine before and after drug infusion were obtained on the 1st, 3rd, and 5th days of antibiotic treatment. Serum urea and creatinine with urinary creatinine, albumin, NAG, lactate dehydrogenase (LDH) and alkaline phosphatase (AP) activity were then determined. A statistically significant increase in urinary NAG, LDH, and AP on 5th day was found compared with before gentamicin administration (P < 0.001, P < 0.01, P < 0.05, respectively). The urinary NAG activity may be a useful indicator of renal injury in children treated with aminoglycosides drugs compared with other routine clinical indicators. PMID:19273542

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.

Drugs that are used to treat Alzheimer's disease include the acetyl cholinesterase inhibitors (ACHIs) donepezil, rivastigmine and galantamine and the NMDA receptor antagonist memantine. Adverse cardiovascular events with these drugs are very uncommon. However, there is evidence that ACHI therapy is associated with a small but significant increase in the risk of syncope and bradycardia. There are also a few reports that these drugs may occasionally be associated with QT prolongation and torsades de pointes ventricular tachycardia. Adverse cardiovascular effects of ACHIs including syncope and bradycardia are less common than their adverse gastrointestinal effects, but they remain important considerations in susceptible individuals. In contrast, animal studies and some observational studies suggest that ACHIs may reduce myocardial infarction and cardiovascular mortality and have favourable effects on hemodynamics and survival in heart failure. Further research is required to confirm these potential beneficial effects. Little is known about the cardiovascular effects of memantine but there have been reports of bradycardia and reduced cardiovascular survival associated with its use. PMID:24777654

Religiosity is a protective factor against illicit drug use, but further investigation is needed to delineate which components of religiosity are protective against use. A racially diverse sample (N = 962) was surveyed about religiosity, exposure to users, and recent use of marijuana, powder cocaine, ecstasy, and nonmedical use of opioids and amphetamine. Results suggest that identifying as Agnostic increased odds of use for each of the five drugs; however, this effect disappeared when controlling for religious importance and attendance. High levels of religious attendance were protective against recent use of marijuana and cocaine, but protective effects diminished when controlling for exposure to users, which was a robust predictor of use of every drug. Religion is a protective mechanism against drug use, but this effect may diminish in light of exposure to users. Alternative preventative methods need to be directed toward individuals who are not religious or are highly exposed to users. PMID:23114835

Despite the high prevalence of hepatitis C virus (HCV) infection among drug users enrolled in methadone maintenance treatment programs, few drug users are being treated with combination therapy. The most significant barrier to treatment is lack of access to comprehensive HCV-related care. We describe a pilot program to integrate care for HCV infection with substance abuse treatment in a setting of maintenance treatment with methadone. This on-site, multidisciplinary model of care includes comprehensive screening and treatment for HCV infection, assessment of eligibility, counseling with regard to substance abuse, psychiatric services, HCV support groups, directly observed therapy, and enhanced linkages to a tertiary care system for diagnostic procedures. Our approach has led to high levels of adherence, with liver biopsy and substantial rates of initiation of antiviral therapy. Two cases illustrate the successful application of this model to patients with HCV infection complicated by active substance abuse and psychiatric comorbidity. PMID:15768345

Analyses were conducted to compare rates of employment before, during, and after employment at the therapeutic workplace, which is a novel employment-based treatment for drug misuse. Participants in two clinical trials attended the therapeutic workplace at higher rates than they worked before intake and six months after discharge. These data suggest that unemployed chronic drug misusers will attend work at higher rates at the therapeutic workplace than in the community when paid modest wages, and that the failure of chronic drug misusers to obtain employment in the community may not result from lack of interest in work.

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

Melanoma originated from melanocytes is the most aggressive type of skin cancer with limited treatment options. New targeted therapeutic options with the discovery of BRAF and MEK inhibitors have shown significant survival benefits. Despite the recent progress, development of chemoresistance and systemic toxicity remains a challenge for treating metastatic melanoma. While the response from the first line of treatment against melanoma using dacarbazine remains only 5–10%, the prolonged use of targeted therapy against mutated oncogene BRAF develops chemoresistance. In this review, we will discuss the nanoparticle-based strategies for encapsulation and conjugation of drugs to the polymer for maximizing their tumor distribution through enhanced permeability and retention effect. We will also highlight photodynamic therapy and design of melanoma-targeted nanoparticles. PMID:26244818

Registered and advanced practice nurses are employed in substance user treatment facilities across the US and in most industrialized countries. Patterns of employment and job descriptions for nurses, however, are highly inconsistent and seriously flawed. Many regulatory system, legislative and government agency factors and to some degree, the nursing profession itself, sustain the flaws and limit the delivery of comprehensive care. Competencies linked to addictions nursing best practices are often underutilized because of narrow job descriptions. This results in limited health and nursing service delivery to vulnerable populations receiving treatment in these government funded programs. This article highlights the increasing demand for the delivery of integrated care to psychiatric and substance using populations. The author considers factors which stake holders can influence to change flawed employment patterns and limited access to comprehensive care for substance users. PMID:26361920

Most of the prostate cancers (PCa) in advanced stage will progress to castration-resistant prostate cancer (CRPC). Within CRPC group, 50-70% of the patients will develop bone metastasis in axial and other regions of the skeleton. Once PCa cells spread to the bone, currently, no treatment regimens are available to eradicate the metastasis, and cancer-related death becomes inevitable. In 2012, it is estimated that there will be 28,170 PCa deaths in the United States. Thus, PCa bone metastasis-associated clinical complications and treatment resistance pose major clinical challenges. In this review, we will present recent findings on the molecular and cellular pathways that are responsible for bone metastasis of PCa. We will address several novel mechanisms with a focus on the role of bone and bone marrow microenvironment in promoting PCa metastasis, and will further discuss why prostate cancer cells preferentially metastasize to the bone. Additionally, we will discuss novel roles of several key pathways, including angiogenesis and extracellular matrix remodeling in bone marrow and stem cell niches with their relationship to PCa bone metastasis and poor treatment response. We will evaluate how various chemotherapeutic drugs and radiation therapies may allow aggressive PCa cells to gain advantageous mutations leading to increased survival and rendering the cancer cells to become resistant to treatment. The novel concept relating several key survival and invasion signaling pathways to stem cell niches and treatment resistance will be reviewed. Lastly, we will provide an update of several recently developed novel drug candidates that target metastatic cancer microenvironments or niches, and discuss the advantages and significance provided by such therapeutic approaches in pursuit of overcoming drug resistance and treating advanced PCa.

Background To date there has been limited research on both the prevalence of overdose and drug user knowledge about overdose prevention and response methods in China. In addition, there has been no effort to integrate naloxone information and distribution into pre-release services for drug users detained in isolated compulsory detoxification facilities in China. Methods The authors conducted a survey of 279 heroin users in isolated compulsory detoxification centers in Ningbo, China in an attempt to evaluate the possibility of conducting prelease peer naloxone programs in Ningbo isolated compulsory detoxification centers. Respondents' demographic background, history of heroin overdoses, and attitudes/knowledge about overdose prevention and response were collected. Results While drug users in Ningbo's compulsory detoxification centers have limited understandings of how to effectively respond to overdoses, they expressed concern about the possibility of overdose, interest in participating in overdose prevention and response programs, and a willingness to help their peers. In general, there was no significant difference in history and attitudes/knowledge of overdose between male and female participants. Conclusion Based on the findings of this research, our survey provides preliminary evidence that detained drug users have considerable interest in overdose prevention and response information and willingness to help peers. However, drug users in Ningbo isolated compulsory detoxification centers currently have limited understandings of effective ways of helping to prevent overdose deaths. PMID:22316338

Harm reduction is a controversial model for treating drug users, with little formal research available on its operation and effectiveness. In order to advance the field, we first conducted participatory research of harm reduction with 120 clients using nominal-group technique to develop culturally relevant outcomes to measure progress. Second, we conducted focus group interviews with a different group of clients to help validate the outcomes. Third, we used the outcomes in an evaluation of the largest harm reduction program in New York City, which involved a representative sample of 261 and entailed baseline, post, and six follow-up assessments. The participatory research resulted in outcomes of 10 life areas important to drug users. Evaluation results showed that program participants made positive improvements across most outcomes, with the most substantial progress made in how clients dealt with drug-use problems. Along with their participation in the program, progress in some outcomes was also associated with clients' type of drug use (i.e., stable vs. chaotic), where more stable drug use was associated with better ways of making an income and types of housing. Surprisingly, progress was not associated with the kinds or numbers of services received or the length of time in the program. This was attributed to the service delivery model of harm reduction, in which clients are less inclined to associate their success with a single staff person or with a single service or intervention received than with the program as a whole.

This article discusses the programs of nongovernmental organizations (NGOs) towards the drug practices and sexual behaviors of HIV infected individuals and drug users in Mykolaiv, Ukraine. Blagodiynist (Charity Foundation), one of the NGOs operating in Ukraine, has been helping drug users and sex workers. This group has collaborated with other group projects to produce better and effective interventions. As such, the needle-exchange project was organized, where drug users could not only exchange needles for clean ones, but also obtain information, advice, and even condoms. Role model stories approach was also another effective method that Blagodiynist utilized to make drug users and sex workers aware not only of the risk and reality of HIV, but to encourage behavior change as well, and to generate the self-confidence needed to alter their erroneous practices. The fact that sex workers and drug users have begun to take the risks of HIV infection seriously and have taken measures to protect themselves, reflect the success of these programs. PMID:12322332

Motivation for drug use treatment is widely regarded as crucial to a client's engagement in treatment and success in quitting drug use. Motivation is typically measured with items reflecting high treatment readiness (e.g., perceived need for treatment and commitment to participate) and low treatment resistance (e.g., skepticism regarding benefits of treatment). Building upon reactance theory and the psychotherapeutic construct of resistance, we conceptualized these two aspects of treatment motivation - readiness and resistance - as distinct constructs and examined their predictive power in a sample of 1295 drug-using offenders referred to treatment while on probation. The sample was 60.7% African Americans, 33.5% non-Hispanic Whites, and 21.2% women; their ages ranged from 16 to 63 years old. Interviews occurred at treatment entry and 6 months later. Readiness (but not resistance) predicted treatment retention during the 6-month period. Resistance (but not readiness) predicted drug use, especially among offenders for whom the treatment referral was coercive. These findings suggest that readiness and resistance should both be assessed among clients entering treatment, especially when the referral is coercive. Intake and counseling protocols should address readiness and resistance separately. PMID:16051447

Background 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. Methods and Findings 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. Conclusions 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
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
Health promotion materials on hepatitis C prevention and safe injecting enjoin injecting drug users to produce ethical selves through relatively rigid social and hygiene-related conduct. This article examines a sample of safe injecting and hepatitis C prevention health promotion materials, and interview data gathered from injecting drug users, to consider the ways in which the notion of individual responsibility functions within them. I argue that the primacy of the individual in western culture is indeed reflected in hepatitis C and safe injecting materials and, that for a range of reasons, injecting drug users also make use of notions of individual responsibility. The article concludes by considering the social and health implications of this individualist approach to injecting drug use and health promotion, and by suggesting ways in which effective materials which do not focus solely on the individual can be created.

This qualitative study aimed to understand the meaning of drug consumption from the view of users who receive care in an outpatient clinic of a Mental Health Service on an island of the Cape Verde archipelago. The methodological framework was based on the Data-founded Theory, in the light of Symbolic Interactionism. Participants were nine drug users from the mentioned outpatient clinic. Recorded interviews and observation were the strategies for data collection. The comparative data analysis resulted in the central phenomenon An attractive force, which expresses the great difficult users have to stop the abusive consumption of psychoactive substances, knowing that all problems faced in the personal, familiar and social areas come from drug habituation. Thus, this study permitted the identification of vulnerable points for possible action by the health team, aiming for the prevention of drug abuse. PMID:20694429

Treatment for acute hepatitis C virus (HCV) infection has significantly better outcomes than treatment for chronic infection. The short window of the acute period poses challenges for young injection drug users (IDU), who are at highest risk of HCV infection, to demonstrate treatment candidacy. We recruited patients with acute HCV from a prospective cohort study to examine clinical and behavioral issues related to treatment candidacy. We report on outcomes and how nursing case management affected candidacy. All five acutely-infected participants reported daily drug use at baseline. All established primary care and decreased their drug use. None received treatment for their acute infection; one was treated within 12 months of infection. Establishing treatment candidacy for young IDU in the acute phase involves various health domains. An acute infection's short period poses many challenges to establishing candidacy, but it is a window of opportunity to engage young IDU in health care. PMID:21497111

Background Increasing numbers of injecting drug users are presenting to primary care and a growing number of general practices are specifically providing care for homeless people. Injecting drug users are at the greatest risk of hepatitis C infection and homeless drug misusers, because of their drug-taking behaviour and patterns, have been identified as being at greater risk of harm of blood-borne diseases than the general population. However, little work has been conducted with injecting drug users or homeless people who have hepatitis C and little is known about how the virus may affect them. Aim To explore the impact of a positive hepatitis C diagnosis on homeless injecting drug users. Design of study This study employed qualitative research. In-depth interviews allowed the exploration of the impact of a potentially life-threatening diagnosis within the context of a person's expressed hierarchy of needs. Setting A primary care centre for homeless people in the north of England. Method In-depth interviews about the impact of a positive hepatitis C diagnosis on their lives were conducted with 17 homeless injecting drug users who had received a positive hepatitis C diagnosis. The interviews were audiotaped, transcribed, and analysed using the framework approach. Results Receiving a positive diagnosis for hepatitis C resulted in feelings of shock, devastation, disbelief, anger, and questioning. A positive diagnosis had lasting social, emotional, psychological, behavioural, and physical effects on homeless injecting drug users, even years after the initial diagnosis. Most responders were diagnosed by a doctor in primary care or by hospital staff; however, not all had sought testing and a number were tested while inpatients and were unaware that blood had been taken for hepatitis C virus serology. Conclusions The implications for clinical policy and primary care practice are discussed, including the issues of patient choice, confidentiality, and pre- and post

We present the first fatal case of extensively drug-resistant tuberculosis (XDR-TB) in an injecting drug user (IDU) in Athens, Greece, co-infected with human immunodeficiency virus and hepatitis C virus and discuss the implications for public health. Despite immediate initiation of treatment, the patient's condition gradually deteriorated and he died 16 days after hospital admission because of multiple organ failure. The contact tracing investigation revealed no further infections among the patient's contacts. PMID:23557942

Background/Aims The study compared illegal drug and alcohol use behaviors between medical and nonmedical users of prescription opioids (PO) and nonmedical users with distinct motives to use. Method An ethically-approved cross-sectional study (2010) was conducted on a representative sample of private university students (n=570), using a self-filled anonymous questionnaire. Results About 25% reported using PO only medically and 15% nonmedically. The prevalence of alcohol and illegal drug use was consistently higher among nonmedical than medical PO users. Adjusting for age and gender, lifetime medical users of PO were more likely to use marijuana only (OR=1.8, 95%CI= 1.1, 2.8), while nonmedical users were at higher odds of using marijuana, ecstasy, cocaine/crack, and alcohol problematically. Compared to non-users, students who took PO nonmedically for non-therapeutic reasons were more likely to use various illegal drugs, but nonmedical users who took PO to relieve pain/help in sleep were only more likely to use marijuana (OR=2.5, 95%CI=1.1, 5.4) and alcohol (e.g., alcohol abuse, OR=3.8, 95%CI= 1.4, 10.1). Conclusion Youth who use PO nonmedically to self-treat have a different alcohol and illegal drug-using profile than those who take it for non-therapeutic reasons. PMID:23391856

Psychoactive drug use shows great diversity, but due to a disproportionate focus on problematic drug use, predominant nonproblematic drug use remains an understudied phenomenon. Historic and anecdotal evidence shows that natural sources of "psychedelic" drugs (e.g., mescaline and psilocybin) have been used in religious and spiritual settings for centuries, as well as for psychological self-enhancement purposes. Our study assessed a total of 667 psychedelic drug users, other drug users, and drug nonusers by online questionnaires. Coping, life purpose, and spirituality were measured with the Psychological Immune Competence Inventory, the Purpose in Life test, and the Intrinsic Spirituality Scale, respectively. Results indicate that the use of psychedelic drugs with a purpose to enhance self-knowledge is less associated with problems, and correlates positively with coping and spirituality. Albeit the meaning of "spirituality" may be ambiguous, it seems that a spiritually-inclined attitude in drug use may act as a protective factor against drug-related problems. The autognostic use of psychedelic drugs may be thus hypothesized as a "training situation" that promotes self-enhancement by rehearsing personal coping strategies and by gaining self-knowledge. However, to assess the actual efficiency and the speculated long-term benefits of these deliberately provoked exceptional experiences, further qualitative investigations are needed. PMID:22111402

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.

This paper examines the relationship between housing status and HIV risk using longitudinal, qualitative data collected in 2004-2005, from a purposeful sample of 65 active drug users in a variety of housed and homeless situations in Hartford, Connecticut. These data were supplemented with observations and in-depth interviews regarding drug use behavior collected in 2001-2005 to evaluate a peer-led HIV prevention intervention. Data reveal differences in social context within and among different housing statuses that affect HIV risky or protective behaviors including the ability to carry drug paraphernalia and HIV prevention materials, the amount of drugs in the immediate environment, access to subsidized and supportive housing, and relationships with others with whom drug users live. Policy implications of the findings, limitations to the data and future research are discussed. PMID:19142817

Two methods of drug detection, urinalysis and hair analysis, were compared with respect to the efficiency of identification of drug use in a population of men living on the Arizona-Mexico border. The standard curve of cannabinoids in urine was linear to 20 ng/mL. The GC/MS levels for all cannabinoids combined in urine were very similar to that obtained by radioimmunoassay (RIA), 91% concordance. Similar results were obtained from samples analyzed dually for the cocaine metabolite benzoylecgonine (BE) after spiking. As determined by RIA of urine, 74% of the subjects were positive for cannabinoids. The majority were in the range of 100-1000 ng/mg creatinine. The pattern of excretion of THC metabolites with respect to the verbally reported time of first use was fairly normal, with the peak rate of elimination 13-24 hours following the last reported use. Washed hair samples were extracted by overnight acid hydrolysis. Urine samples and neutralized hair extracts were analyzed for cocaine and BE by RIA. Of the hair samples, 55% contained cocaine/BE, as compared with only 4.3% of the urine samples. Most hair samples contained cocaine/BE in the range of 25-100 ng/sample (100 mg hair). All hair samples testing negative for cocaine/BE by RIA also tested negative by GC/MS, and four samples containing the highest amounts of cocaine and BE by RIA were similarly found to contain the highest amounts by GC/MS. Hair analysis, therefore, gives a wider window of detection of drug use than does urinalysis and shows merit in the confirmation of cocaine use in small clinical research studies. PMID:8336486

Wound botulism is a rare infectious disease that is becoming a frequent complication of parental drug use. Diagnosis is often difficult and based on clinical suspicion. We report the first Italian case of wound botulism due to intramuscular heroin injection in a 48-year-old man with an acute onset of slurred speech and dysphagia. The most considerable finding of electrophysiological study was the reduction in amplitude of compound muscle action potential which should be considered a useful initial electrodiagnostic sign in the clinical context of botulism. Alerting clinicians to botulism is crucial for a rapid diagnosis and appropriate treatment and thus decreasing mortality and complications. PMID:20552239

Background People who are newly diagnosed with pulmonary tuberculosis (TB) typically receive a standard first-line treatment regimen that consists of two months of isoniazid, rifampicin, pyrazinamide, and ethambutol followed by four months of isoniazid and rifampicin. Fixed-dose combinations (FDCs) of these drugs are widely recommended. Objectives To compare the efficacy, safety, and acceptability of anti-tuberculosis regimens given as fixed-dose combinations compared to single-drug formulations for treating people with newly diagnosed pulmonary tuberculosis. Search methods We searched the Cochrane Infectious Disease Group Specialized Register; the Cochrane Central Register of Controlled Trials (CENTRAL, published in the Cochrane Library, Issue 11 2015); MEDLINE (1966 to 20 November 2015); EMBASE (1980 to 20 November 2015); LILACS (1982 to 20 November 2015); the metaRegister of Controlled Trials; and the World Health Organization International Clinical Trials Registry Platform (WHO ICTRP), without language restrictions, up to 20 November 2015. Selection criteria Randomized controlled trials that compared the use of FDCs with single-drug formulations in adults (aged 15 years or more) newly diagnosed with pulmonary TB. Data collection and analysis Two review authors independently assessed studies for inclusion, and assessed the risk of bias and extracted data from the included trials. We used risk ratios (RRs) for dichotomous data and mean differences (MDs) for continuous data with 95% confidence intervals (CIs). We attempted to assess the effect of treatment for time-to-event measures with hazard ratios and their 95% CIs. We used the Cochrane 'Risk of bias' assessment tool to determine the risk of bias in included trials. We used the fixed-effect model when there was little heterogeneity and the random-effects model with moderate heterogeneity. We used an I² statistic value of 75% or greater to denote significant heterogeneity, in which case we did not perform a
The increasing number of law-evading drug users in Japan is becoming a serious social problem. Previous studies have shown that law-evading drug users are younger, more educated, and less antisocial than methamphetamine users. They also tend to have some type of psychiatric disorder before starting drug use; therefore one of the reasons that they start using drugs may be to alleviate certain psychiatric symptoms. Furthermore, if drug users are successful in avoiding arrest, they often lack the motivation to stop, which makes treatment difficult. Therapists are required to be non-confrontational, to keep pace with their patients, and to take their patients' other existing disorders into account. Recently, the Matrix Model has shown promise as a new treatment strategy for drug abusers in Japan. The Matrix Model, which was originally developed in response to the 1980s cocaine epidemic in the USA, is an intensive outpatient treatment approach for drug abuse and dependence. The Matrix Model integrates cognitive-behavioral therapy, contingency management, motivational interviewing, 12-step facilitation, family involvement, and so on, with a directive, non-confrontational approach, and this style of therapy seems to fit with law-evading drug users. A Matrix Model-based treatment program was first established in Japan in 2006. The aim of this report is to introduce and assess the benefits of the TAMA Mental Health and Welfare Center Relapse Prevention Program, a Matrix Model-based treatment program established at the Tama Mental Health and Welfare Center in 2007.

Background Improvement in quality of life (QOL) is a long term goal of drug treatment. Although some brief interventions have been found to reduce illicit drug use, no trial among adult risky (moderate non-dependent) drug users has tested effects on health-related quality of life. Methods A single-blind randomized controlled trial of patients enrolled from February 2011 to November 2012 was conducted in waiting rooms of five federally qualified health centers. 413 adult primary care patients were identified as risky drug users using the WHO-ASSIST and 334 (81% response; 171 intervention, 163 control) consented to participate in the trial. Three-month follow-ups were completed by 261 patients (78%). Intervention patients received the QUIT intervention of brief clinician advice and up to two drug-use health telephone sessions. The control group received usual care and information on cancer screening. Outcomes were three-month changes in the Short Form Health Survey (SF-12) mental health component summary score (MCS) and physical health component summary score (PCS). Results The average treatment effect (ATE) was non-significant for MCS (0.2 points, p-value=0.87) and marginally significant for PCS (1.7 points, p-value=0.08). The average treatment effect on the treated (ATT) was 0.1 (p-value=0.93) for MCS and 1.9 (p-value=0.056) for PCS. The effect on PCS was stronger at higher (above median) baseline number of drug use days: ATE=2.7, p-value=0.04; ATT=3.21, p-value=0.02. Conclusions The trial found a marginally significant effect on improvement in PCS, and significant and stronger effect on the SF-12 physical component among patients with greater frequency of initial drug use.

This study describes, through ethnographic interviews, the treatment experiences of Puerto Rican long-term heroin users who are at extremely high risk for HIV infection and the barriers they perceive to drug treatment. On the basis of this information we suggest policy recommendations for increasing drug treatment access for Puerto Rican long-term injectors of heroin. It is critical that Puerto Rican populations access drug treatment facilities given their risk factors for HIV infection and the high rate of poverty in Puerto Rican communities that exacerbates drug use.

Samples from a self-proclaimed cocaine (COC) user, from 19 drug users (postmortem) and from 27 drug chemists were extensively washed and analyzed for COC, benzoylecgonine, norcocaine (NC), cocaethylene (CE) and aryl hydroxycocaines by liquid chromatography-tandem mass spectrometry. Published wash criteria and cutoffs were applied to the results. Additionally, the data were used to formulate new reporting criteria and interpretation guidelines for forensic casework. Applying the wash and reporting criteria, hair that was externally contaminated with COC was distinguished from hair collected from individuals known to have consumed COC. In addition, CE, NC and hydroxycocaine metabolites were only present in COC users' hair and not in drug chemists' hair. When properly applied, the use of an extended wash, along with the reporting criteria defined here, will exclude false-positive results from environmental contact with COC. PMID:25100648
Background Despite Thailand's official reclassification of drug users as "patients" deserving care and not "criminals," the Thai government has continued to rely heavily on punitive responses to drug use such as "boot camp"-style compulsory "treatment" centers. There is very little research on experiences with compulsory treatment centers among people who use drugs. The work reported here is a first step toward filling that gap. Methods We examined experiences of compulsory drug treatment among 252 Thai people who inject drugs (IDU) participating in the Mitsampan Community Research Project in Bangkok. Multivariate logistic regression was used to identify factors independently associated with a history of compulsory treatment experience. Results In total, 80 (31.7%) participants reported a history of compulsory treatment. In multivariate analyses, compulsory drug detention experience was positively associated with current spending on drugs per day (adjusted odds ratio [AOR] = 1.86; 95%CI: 1.07 - 3.22) and reporting drug planting by police (AOR = 1.81; 95%CI: 1.04 - 3.15). Among those with compulsory treatment experience, 77 (96.3%) reported injecting in the past week, and no difference in intensity of drug use was observed between those with and without a history of compulsory detention. Conclusion These findings raise concerns about the current approach to compulsory drug detention in Thailand. Exposure to compulsory drug detention was associated with police abuse and high rates of relapse into drug use, although additional research is needed to determine the precise impact of exposure to this form of detention on future drug use. More broadly, compulsory "treatment" based on a penal approach is not consistent with scientific evidence on addressing drug addiction and should be phased out in favor of evidence-based interventions.

Longitudinal studies that research homeless persons or transient drug users face particular challenges in retaining subjects. Between 2005 and 2006, 101 mobile young injection drug users were recruited in Los Angeles into a 2-year longitudinal study. Several features of ethnographic methodology, including fieldwork and qualitative interviews, and modifications to the original design, such as toll-free calls routed directly to ethnographer cell phones and wiring incentive payments, resulted in retention of 78% of subjects for the first follow-up interview. Longitudinal studies that are flexible and based upon qualitative methodologies are more likely to retain mobile subjects while also uncovering emergent research findings. PMID:20222779

Buprenorphine (Subutex) is widely abused in Finland. A combination of buprenorphine plus naloxone (Suboxone) has been available since late 2004, permitting a comparison of the abuse of the two products among untreated intravenous (IV) users. A survey was distributed to attendees at a Helsinki needle exchange program over 2-weeks in April, 2005, At least 30% were returned anonymously. Survey variables included: years of prior IV opioid abuse, years of buprenorphine abuse, frequency, dosage, route of administration and reasons for use, concomitant IV abuse of other substances and amount paid on the street for both buprenorphine and buprenorphine+naloxone. Buprenorphine was the most frequently used IV drug for 73% of the respondents. More than 75% said they used IV buprenorphine to self-treat addiction or withdrawal. Most (68%) had tried the buprenorphine+naloxone combination IV, but 80% said they had a "bad" experience. Its street price was less than half that of buprenorphine alone. The buprenorphine+naloxone combination appears to be a feasible tool, along with easier access to addiction treatment, for decreasing IV abuse of buprenorphine. PMID:17055191

Optimal Distinctiveness Theory posits that highly valued groups are those that can simultaneously satisfy needs to belong and to be different. The success of drug-prevention messages with a social-identity theme should therefore depend on the extent to which the group is portrayed as capable of meeting these needs. Specifically, messages that portray non-users as a large and undifferentiated majority may not be as successful as messages that emphasize uniqueness of non-users. This prediction was examined using marijuana prevention messages that depicted non-users as a distinctive or a majority group. Distinctiveness characterization lowered behavioral willingness to use marijuana among non-users (Experiment 1) and served as a source of identity threat (contingent on gender) among users (Experiment 2).

Objective To systematically review factors associated with HIV disease progression among illicit drug users, focusing on exposures exogenous to individuals that likely shape access and adherence to HIV treatment. Design A systematic review of peer-reviewed English-language studies among HIV-seropositive illicit drug users with at least one of these endpoint of interest: a diagnosis of AIDS; death; changes/differences in CD4 cell counts; or changes/differences in plasma HIV-1 RNA levels. Methods Articles were included if they reported factors associated with an outcome of interest among a group of illicit drug users. Studies were identified, screened and selected using systematic methods. Results Of 2,668 studies matching the search criteria, 58 (2%) met the inclusion criteria, all but one from North America or Western Europe. Overall, 41 (71%) studies contained significant individual-level clinical characteristics or behaviours (e.g., illicit drug use) associated with disease progression. Fifteen studies (26%) identified significant social, physical, economic or policy-level exposures, including incarceration, housing status or lack of legal income. Conclusion While past studies demonstrate important environmental exposures that appear to shape access to care and subsequent disease progression, the limited literature to examine these factors demonstrates the need for future research to consider risk environment characteristics and the role they may play in shaping health outcomes from HIV infection among drug users through determining access and adherence to evidence-based care.

In the aftermath of Hurricane Katrina, the majority of routine activities in New Orleans were disrupted, including the illegal drug market. The large-scale relocation of New Orleans evacuees (NOEs), including many illegal drug users and sellers, to host cities led to a need for new sources of illegal drugs. This need was quickly satisfied by two initially distinct drug markets (1) drug dealers from New Orleans who were themselves evacuees and (2) established drug dealers in the host cities. To be expected, the two markets did not operate indefinitely in parallel fashion. This paper describes the evolving, operational relationship between these two drug markets over time, with a focus on Houston. We analyze the reciprocal evolution of these two markets at two significant points in time: at the beginning of the relocation (2005) and two years later (2007). The overall trend is towards a melding of the two drug markets, as evidenced primarily by decreases in drug-related violence and the cross-fertilization of drug tastes. We describe the process by which the two drug markets are melded over time, in order to seek a better understanding of the social processes by which drug markets in general evolve. PMID:20509741

In the aftermath of Hurricane Katrina, the majority of routine activities in New Orleans were disrupted, including the illegal drug market. The large-scale relocation of New Orleans evacuees (NOEs), including many illegal drug users and sellers, to host cities led to a need for new sources of illegal drugs. This need was quickly satisfied by two initially distinct drug markets (1) drug dealers from New Orleans who were themselves evacuees and (2) established drug dealers in the host cities. To be expected, the two markets did not operate indefinitely in parallel fashion.

Young female injection drug users (IDUs) are at risk for HIV/HCV, and initiating the use of a new drug may confer additional and unexpected risks. While gender differences in the social context of injection drug use have been identified, it is unknown whether those differences persist during the initiation of a new drug. This mixed-methods study examined the accounts of 30 young female IDUs in Los Angeles, CA, USA from 2004 to 2006, who described the social context of initiating injection drug use and initiating ketamine injection. The analysis aimed to understand how the social context of young women's injection events contributes to HIV/HCV risk. Women's initiation into ketamine injection occurred approximately 2 years after their first injection of any drug. Over that time, women experienced changes in some aspects of the social context of drug injection, including the size and composition of the using group. A significant proportion of women described injection events characterized by a lack of control over the acquisition, preparation, and injection of drugs, as well as reliance on friends and sexual partners. Findings suggest that lack of control over drug acquisition, preparation, and injection may elevate women's risk; these phenomena should be considered as a behavioral risk factor when designing interventions.

This study examined and compared the effectiveness of two counseling interventions designed to reduce the HIV drug and sexual risk behaviors of 684 out-of-treatment drug users recruited from South Philadelphia, PA. All study participants received a standard intervention and one half were randomly assigned to also receive the enhanced intervention. The standard intervention provided HIV risk reduction education, HIV testing with pretest and posttest counseling, and training in condom use and needle cleaning. The enhanced intervention provided additional information on STD risk reduction. Both interventions were effective in influencing behavior change between baseline and 6-month follow-up. A higher proportion of persons reduced their drug risk behaviors compared to their sexual risk behaviors. As sexual risk behaviors are more resistant to change, there is a need for tailored interventions that target out-of-treatment drug users. PMID:9505096

A 26-year-old drug abuser who presented with sepsis was found to have a pseudoaneurysm in the left vertebral artery. This aneurysm was presumed to be post-traumatic, since the patient reported multiple attempts to inject drugs in the left jugular vein 15 days prior to admission. The pseudoaneurysm was treated effectively with stent-graft placement.
A key reason for hosting AIDS 2010 in Vienna was to highlight the spread of HIV through injecting drug use, something that has reached crisis proportions in many parts of Eastern Europe and the former Soviet Union. In this article, based on a presentation at the conference, Anna Zakowicz discusses the options for promoting policy advocacy for female injecting drug users (IDUs) in Central and Eastern Europe.

BACKGROUND: The government encourages general practitioners (GPs) to become involved in caring for drug users. However, in some areas of the country, including Bedford, secondary care support is inadequate. GPs in these areas have to decide how to cope with such patients entirely within general practice. AIM: To assess the characteristics and quality of care given without secondary care support to drug users by one practice in Bedford over a decade. METHOD: A search was made of the practice computer for all patients with a problem title of 'addiction drug' between 1986 and 1995. The age, sex, social characteristics, and drug history were recorded. RESULTS: One hundred and ninety-two patients were found, of which 155 took part in the practice programme; i.e. they consulted more than three times. Forty-three patients (37%) who took part and were prescribed Methadone were prescribed this drug as ampoules. Sixty-three patients (40.6%) who took part in the programme stopped using drugs. Thirty-two (33.6%) of the Methadone users became abstinent. A higher proportion of women (13-48%) than men (19-27.7%) stopped using Methadone (P = 0.019). Among patients who had a stable lifestyle, a higher proportion had been prescribed ampoules than mixture (22 out of 28: 78.6%; P = 0.001). Similarly, of those who had a job, eight out of 11 (72%; P = 0.037) had been prescribed methadone ampoules. Two-thirds of all patients prescribed amphetamines stopped using drugs. CONCLUSION: Long-term care of drug users entirely within general practice is feasible. Among those prescribed methadone ampoules, a higher than average proportion had stable lifestyles and had a stable job. PMID:10071402

Relatively few studies have addressed the psychometric properties of self-report measures of amphetamine use. This study examines the reliability and validity of the Risk Behavior Assessment's (RBA) lifetime and recent amphetamine-use questions. To evaluate validity, 4027 out-of-treatment primarily cocaine and heroin users provided urine samples that were compared to self-report data; to evaluate reliability, 218 completed the RBA at two time points, 48 hours apart. In the overall sample, self-reports demonstrated moderately high validity, with a 95% accuracy rate (kappa =.54). When analysis was restricted to recent amphetamine users validity was slightly lower (71.5% accuracy; kappa = .41). Test-retest data indicated good reliability for self-reports of ever having used amphetamine (kappa =.79), and amphetamine use in the past 30 days (.75 < r < .91). Out-of-treatment drug users provided accurate self-reports of amphetamine use. Reliable and valid measures are essential for describing and predicting trends in amphetamine use, evaluating the effectiveness of interventions, and developing policies and programs. PMID:20053503

Objectives. We sought to identify correlates of reported lifetime diagnoses of TB among injection drug users in the border city of Tijuana, Mexico. Methods. Injection drug users in Tijuana were recruited into a prospective cohort study during 2006 and 2007. We used weighted multivariate logistic regression to identify correlates of TB diagnoses. Results. Of the 1056 participants, 103 (9.8%) reported a history of TB, among whom 93% received anti-TB medication and 80% were diagnosed in the United States. Treatment was prematurely halted among 8% of patients; deportation from the United States was the cause of half of these treatment interruptions. History of travel to (odds ratio [OR] = 6.44; 95% confidence interval [CI] = 1.53, 27.20) or deportation from (OR = 1.83; 95% CI = 1.07, 3.12) the United States and incarceration (OR = 2.20; 95% CI = 1.06, 4.58) were independently associated with a reported lifetime diagnosis of TB. Conclusions. Mobility and migration are important factors in identifying and treating TB patients diagnosed in the US–Mexico border region. Strengthening capacity on both sides of the border to identify, monitor, and treat TB is a priority. PMID:19542040
Thai females injecting drugs are ensnared in a web of problems arising from forms of prejudice that magnify their vulnerability. They are vulnerable, at risk, and exposed to a high degree of social suffering. This paper aims to elucidate how social production and structural violence combine to shape the lives of these women. Using a qualitative methodology, two focus groups with 5 key informants and in-depth interviews involving a total of 35 women injecting drugs were conducted in Bangkok. The findings reveal that the structural environment that directly impacts upon these women's lives becomes the reason for their suffering. The structural environment puts these women at risk of violence in numerous social settings in which these women engage as well as generating tension at a subjective level (i.e. the habitus) of these women. Thai female injecting drug users are trapped in a difficult tension between the demands for being Thai women seeking to exist in the masculine world of drug use but at the same time meeting Thai society's expectations of womanhood. Unequal gender relations are manifest in the everyday violence that women face in the drug community, culminating in the essential nature of women being questioned, undermined and threatened. Living in the drug community, women are subjected to violence and harassment, and gendered brutality by intimate partners. In conclusion, the social suffering that Thai female injecting drug users find themselves confronting is confined to dilemmas cause by tensions between drug use and the overriding gender habitus.

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

Background Nonmedical prescription opioid use has emerged as a major public health concern in recent years, particularly in rural Appalachia. Little is known about the routes of administration (ROA) involved in nonmedical prescription opioid use among rural and urban drug users. The purpose of this study was to describe rural-urban differences in ROA for nonmedical prescription opioid use. Methods A purposive sample of 212 prescription drug users was recruited from a rural Appalachian county (n = 101) and a major metropolitan area (n = 111) in Kentucky. Consenting participants were given an interviewer-administered questionnaire examining sociodemographics, psychiatric disorders, and self-reported nonmedical use and ROA (swallowing, snorting, injecting) for the following prescription drugs: buprenorphine, fentanyl, hydrocodone, hydromorphone, methadone, morphine, OxyContin® and other oxycodone. Results Among urban participants, swallowing was the most common ROA, contrasting sharply with substance-specific variation in ROA among rural participants. Among rural participants, snorting was the most frequent ROA for hydrocodone, methadone, OxyContin®, and oxycodone, while injection was most common for hydromorphone and morphine. In age-, gender-, and race-adjusted analyses, rural participants had significantly higher odds of snorting hydrocodone, OxyContin®, and oxycodone than urban participants. Urban participants had significantly higher odds of swallowing hydrocodone and oxycodone than did rural participants. Notably, among rural participants, 67% of hydromorphone users and 63% of morphine users had injected the drugs. Conclusions Alternative ROA are common among rural drug users. This finding has implications for rural substance abuse treatment and harm reduction, in which interventions should incorporate methods to prevent and reduce route-specific health complications of drug use.

Background It is not yet known if the increased risk of suicide in substance abusers is caused by the causal and/or coexisting relationship between substance use and psychiatric disorders. This study was designed to estimate the suicide risk among individuals with illicit drug use alone, illicit drug users with mental disorders, and illicit drug users with alcohol use disorders. Methods Subjects were participants of the 2008 Thai National Mental Health Survey. They were asked for their illicit drug use in the past year. The Mini International Neuropsychiatric Interview (MINI), current suicidality (1 month prior to assessment), mood episodes, anxiety disorders, psychotic disorders, and alcohol use disorders were used for assessing mental/alcohol use disorders. A score of 1 or more for the MINI–Suicidality module was defined as the presence of suicide risk. Results Of the total 17,140 respondents, 537 currently used illicit drugs, while 1,194 respondents had a suicide risk. Common illicit drugs were kratom (59%) and (meth)amphetamine (24%). Compared with 16,603 Thais without illicit drug use, the illicit drug users with or without mental/alcohol use disorders (n=537) had an increased risk of suicide (adjusted odds ratio [OR], 95% confidence interval [CI] =2.09, 1.55–2.81). While those who used illicit drugs alone (no mental/alcohol use disorder) (n=348) had no increased risk of suicide (adjusted OR, 95% CI =1.04, 0.66–1.65), the illicit drug users with mental or alcohol use disorders (n=27 and n=162, respectively) had significantly increased risk of suicide (adjusted ORs, 95% CIs =14.06, 6.50–30.3 and 3.14, 1.98–4.99, respectively). Conclusion A key limitation of this study was the combined suicidal behaviors as a suicidality risk. Mental or alcohol use disorders found in this population actually increased the suicide risk. These findings support the coexisting relationship that mental and alcohol use disorders play a vital role in increasing the suicide

Trained interviewers spoke to 957 drug users attending a detoxification program, methadone maintenance program, or a research storefront in New York City in 1990-91 and to 601 drug users attending 17 drug use treatment clinics in Bangkok, Thailand, in the autumn of 1989 as part of a study to identify factors linked to the probability or failure of condom use with primary sexual partners among IV drug users. The participants also received HIV counseling and testing. IV drug users in New York City were more likely to be older (36.2 years vs. 30.1 years; p .001), female (25% vs. 5%; p .001), more ethnically diverse (p .001), and inject cocaine more often (33 injections/month vs. 0.5 injections/month) than those in Bangkok. 44% of drug users in New York City and 33% of those in Bangkok engaged in some unprotected penetrative intercourse with a primary heterosexual partner in the previous 6 months. Of drug users having penetrative sexual intercourse with a primary partner in the previous 6 months, 20% in New York City and 12% in Bangkok always used condoms (p .02). The strongest predictors of condom use among IV drug users from both countries were a previous positive HIV test and talking about AIDS with sexual partners (p = .001 for US; p = .0008 for Bangkok and p = .004 for US; p = .0596 for Bangkok, respectively). These findings indicated that unsafe sexual behavior with primary sexual partners among drug users is still a major source of HIV transmission in these 2 cities. Nevertheless, knowledge of HIV positive status and partner communication concerning AIDS are predictors of condom use shared by both groups. Thus, HIV/AIDS prevention programs should provide confidential HIV testing and counseling for drug users and should encourage frank discussions of AIDS between drug users and primary sexual partners. Peer support for risk reduction among drug users has the potential to facilitate such discussions. PMID:8363764

Drug treatment facilities are important sites for providing targeted prevention and health services to injection drug users (IDUs) who are infected with the hepatitis C virus (HCV). A nationwide survey was conducted to examine whether differences exist in the HCV-related services provided by drug treatment programs that have varying proportions of IDUs among their patients. The results indicate that, overall, drug treatment programs with a greater proportion of IDUs offer significantly more HCV services as compared to programs with a smaller proportion of IDUs. However, important components of hepatitis C-related care, such as universal basic education and counseling about HCV and extensive HCV-antibody testing, are not yet being provided by all programs with a large proportion of IDUs among their patient populations.

Injection drug users (IDUs) are at increased risk of contracting HIV. From a clinical trial assessing an intervention to enhance the linkage of hospitalized patients to opioid treatment after discharge, we conducted multivariate analysis of baseline data from hospitalized IDUs with a history of opioid dependence (n = 104) to identify differences in factors predicting HIV drug and sex risk behaviors. Factors significantly associated with HIV drug risk were being non-Hispanic Caucasian and recent cocaine use. Being female, binge drinking, and poorer mental health were significantly associated with higher sex risk. Because factors predicting HIV sex risk behaviors differ from those predicting HIV drug risk, interventions aimed at specific HIV risks should have different behavioral and substance use targets.

Infective endocarditis caused by Klebsiella species is rare, with most isolates being K. pneumoniae. We report the case of a 24-year-old intravenous drug user with newly diagnosed seminoma who developed K. oxytoca endocarditis. In addition to having K. oxytoca isolated from blood culture, cultures of that species were obtained from a retroperitoneal metastasis found on original presentation. PMID:27034562

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.

Blood-borne viral infections (BBVIs) are important health consequences of illicit drug use. This study assessed predictors of inpatient hospital admissions for BBVIs in a cohort of 4817 clients seeking treatment for drug use in Finland. We examined clients' data on hospital admissions registered in the Finnish National Hospital Discharge Register from 1997 to 2010 with diagnoses of BBVIs. Cox proportional hazards regression analyses were separately conducted for each of the three BBVI groups to test for association between baseline variables and hospitalizations. Findings were reported as adjusted hazard ratios (aHRs). Based upon primary discharge diagnoses, 81 clients were hospitalized for HIV, 116 for hepatitis C, and 45 for other types of hepatitis. Compared to those admitted for hepatitis C and other hepatitis, drug users with HIV had higher total number of hospital admissions (294 versus 141 and 50 respectively), higher crude hospitalization rate (7.1 versus 3.4.and 1.2 per 1000 person-years respectively), and higher total length of hospital stay (2857 days versus 279 and 308 respectively). Trends in hospitalization for all BBVI groups declined at the end of follow-up. HIV positive status at baseline (aHR: 6.58) and longer duration of drug use (aHR: 1.11) were independently associated with increased risk for HIV hospitalization. Female gender (aHR: 3.05) and intravenous use of primary drug (aHR: 2.78) were significantly associated with HCV hospitalization. Having hepatitis B negative status at baseline (aHR: 0.25) reduced the risk of other hepatitis hospitalizations. Illicit drug use coexists with blood-borne viral infections. To address this problem, clinicians treating infectious diseases need to also identify drug use in their patients and provide drug treatment information and/or referral. PMID:25736625

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

The key to the future of the HIV epidemic is the intravenous drug user. In New York City the future has arrived--intravenous drug use is now the predominant risk factor among new cases of AIDS. Our limited knowledge of most facets of drug abuse prevention and treatment and the emotional polarity and politicalization of the issues surrounding AIDS have made control of its spread among intravenous drug users very difficult. Clearly new research efforts are needed better to decide how to reduce the further spread of HIV infection among this group. But efforts to stop the spread cannot await these results. Intense and immediate efforts should focus on five areas for potential control of the spread of HIV infection among drug users: education, treatment on demand, expanding support services, providing sterile equipment, and readjustment of some of society's moral judgments that currently block action. Let us hope that in 10 years we do not look back and realize that we did too little too late while it was still possible to make a difference. PMID:2695203

Drug abuse is one of the major public health problems in Nepal. The objective of this study is to explore the factors responsible for the injecting drug use in Nepal. A cross sectional study was conducted among drug users in Pokhara sub metropolitan city in Nepal. Taking prevalence of 20% at 95% confidence interval and 20% non-response rate, 448 samples were calculated for face to face interviews. Most of the study participants were >24 year's age. Sixty-one percentage of the participants were unemployed. The largest percentage belonged to Gurung/Rai/Pun (37%) ethnic groups, and had completed secondary level of education (47.5%). In the logistic regression analysis occupation, motivating factors for drug use, ever been to custody, age at first drug use, age at first sex, money spent on drugs, ever been rehabilitated and age of the respondents showed a statistically significant association with injecting drug use status. The respondents having business [Adjusted Odds ratio (aOR) 4.506, 95% CI (1.677-12.104)], service [aOR 2.698, 95% CI (a1.146-6.355], having tragedy/turmoil [aOR 3.867, 95% CI (1.596-9.367)], family problem [aOR 2.010, 95% CI (2.010-53.496)], had sex at >19 years [aOR 1.683, 95% CI (1.017-2.785)], rehabilitated >2 times [aOR 4.699, 95% CI (1.401-15.763)], >24 years age group [aOR 1.741, 95% CI (1.025-2.957)] had higher odds of having injecting habits. Having money spent on drugs >3,000 NRs (300 USD) [aOR 0.489, 95%CI (0.274-0.870), not been to custody (aOR 0.330, 95%CI (0.203-0.537)] and having curiosity for drug use [aOR 0.147, 95% CI (0.029-0.737)] were found to be protective for injecting drug use. This study recommends the harm reduction program specifically focused on drug users of occupational groups like business, service and the youths through public health actions to stop transiting them to injecting drug use.

This article presents an analysis of the partial results from a quantitative study that addresses the perspective of drug users' family and friends regarding the treatment of problems resulting from the use of illicit drugs. Participants were 104 health service users in Bogotá. Of the participants, 58% consider that drug use is a disease that needs treatment; 56% stated the general hospital as the main alternative for treatment; 95% reported that the state accounted for this situation. Participants were more acquainted with private institutions, with therapeutic communities and religious groups being reported as the ones with the strongest commitment to the problem. For 73% of participants, the existing services are inappropriate and of difficult use and access. Stigma is the main barrier for a person to seek health care, and only 50% believe there is any use in treatments. There is a need for broader dissemination of the existing resources so as to increase their implementation and use. PMID:20011903

Cigarette smoking is ubiquitous among illicit drug users. Some have speculated that this may be partially due to similarities in the route of administration. However, research examining the relationship between cigarette smoking and routes of administration of illicit drugs is limited. To address this gap, we investigated sociodemographic and drug use factors associated with cigarette smoking among cocaine and heroin users in the Baltimore, Maryland community (N=576). Regular and heavy cigarette smokers were more likely to be White, have a history of a prior marriage, and have a lower education level. Regular smoking of marijuana and crack was associated with cigarette smoking, but not heavy cigarette smoking. Injection use was more common among heavy cigarette smokers. In particular, regular cigarette smokers were more likely to have a lifetime history of regularly injecting heroin. Optimal prevention and treatment outcomes can only occur through a comprehensive understanding of the interrelations between different substances of abuse. PMID:22305644

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

Objectives The current study examined how drinking severity among injection and non-injection drug users is associated with sex risk behaviors and risk of HIV exposure. Methods The study is a secondary analysis of an investigation of risk factors among drug users in Baltimore known as the NEURO-HIV Epidemiologic Study. Participants (N = 557) completed an interview, self-reported 30-day alcohol use, lifetime injection and non-injection drug use, and provided blood samples to screen for HIV. Participants were grouped into one of three drinking severity conditions: Abstinent (no reported alcohol use in prior 30-days), Moderate Alcohol Use (≤30 drinks for females, or ≤ 60 drinks for males), or Problematic Alcohol Use (>30 drinks for females, or >60 drinks for males). Drinking severity groups were significantly different on lifetime injection drug use, heroin injection, snorting/sniffing cocaine, and smoking crack. Results Logistic regression analyses found problematic alcohol users to be more likely than alcohol abstainers to inject drugs before or during sex (AOR = 5.78; 95% CI = 2.07-16.10), and more likely than moderate alcohol users to use alcohol before/during sex (AOR = 4.96; 95% CI = 2.09-11.81), inject drugs before/during sex (AOR = 2.96; 95% CI = 1.29-6.80) and to be HIV+ among Black participants (AOR = 2.72; 95% CI = 1.14-6.49). Conclusions These results outline the necessity for research and clinical intervention among this population to reduce sex risk behaviors and potential HIV exposure, while highlighting the need to examine drinking severity as a predictor of sex risk behaviors.

Limited drug penetration is an obstacle that is often encountered in treatment of central nervous system (CNS) diseases including pain and cerebral hypoxia. Over the past several years, biochemical characteristics of the brain (i.e., tight junction protein complexes at brain barrier sites, expression of influx and efflux transporters) have been shown to be directly involved in determining CNS permeation of therapeutic agents; however, the vast majority of these studies have focused on understanding those mechanisms that prevent drugs from entering the CNS. Recently, this paradigm has shifted toward identifying and characterizing brain targets that facilitate CNS drug delivery. Such targets include the organic anion–transporting polypeptides (OATPs in humans; Oatps in rodents), a family of sodium-independent transporters that are endogenously expressed in the brain and are involved in drug uptake. OATP/Oatp substrates include drugs that are efficacious in treatment of pain and/or cerebral hypoxia (i.e., opioid analgesic peptides, 3-hydroxy-3-methylglutaryl coenzyme A reductase inhibitors). This clearly suggests that OATP/Oatp isoforms are viable transporter targets that can be exploited for optimization of drug delivery to the brain and, therefore, improved treatment of CNS diseases. This review summarizes recent knowledge in this area and emphasizes the potential that therapeutic targeting of OATP/Oatp isoforms may have in facilitating CNS drug delivery and distribution. Additionally, information presented in this review will point to novel strategies that can be used for treatment of pain and cerebral hypoxia. PMID:23343976

A variety of preclinical models have been constructed to emphasize unique aspects of addiction-like behavior. These include Negative Reinforcement ("Pain Avoidance"), Positive Reinforcement ("Pleasure Seeking"), Incentive Salience ("Craving"), Stimulus Response Learning ("Habits"), and Inhibitory Control Dysfunction ("Impulsivity"). We used a survey to better understand why methamphetamine-dependent research volunteers (N = 73) continue to use methamphetamine, or relapse to methamphetamine use after a period of cessation of use. All participants met DSM-IV criteria for methamphetamine abuse or dependence, and did not meet criteria for other current Axis I psychiatric disorders or dependence on other drugs of abuse, other than nicotine. The questionnaire consisted of a series of face-valid questions regarding drug use, which in this case referred to methamphetamine use. Examples of questions include: "Do you use drugs mostly to make bad feelings like boredom, loneliness, or apathy go away?", "Do you use drugs mostly because you want to get high?", "Do you use drugs mostly because of cravings?", "Do you find yourself getting ready to take drugs without thinking about it?", and "Do you impulsively take drugs?". The scale was anchored at 1 (not at all) and 7 (very much). For each question, the numbers of participants rating each question negatively (1 or 2), neither negatively or affirmatively (3-5), and affirmatively (6 or 7) were tabulated. The greatest number of respondents (56%) affirmed that they used drugs due to "pleasure seeking." The next highest categories selected were "impulsivity" (27%) and "habits"(25%). Surprisingly, many participants reported that "pain avoidance" (30%) and "craving" (30%) were not important for their drug use. Results from this study support the contention that methamphetamine users (and probably other drug users as well) are more heterogeneous than is often appreciated, and imply that treatment development might be more successful if

An analysis of a case-control study of rhabdomyolysis was conducted to screen for previously unrecognized cytochrome P450 enzyme (CYP) 2C8 inhibitors that may cause other clinically important drug-drug interactions. Medication use in cases of rhabdomyolysis using cerivastatin (n = 72) was compared with that in controls using atorvastatin (n = 287) for the period 1998-2001. The use of clopidogrel was strongly associated with rhabdomyolysis (odds ratio (OR) 29.6; 95% confidence interval (CI), 6.1-143). In a replication effort that used the US Food and Drug Administration (FDA) Adverse Event Reporting System (AERS), it was found that clopidogrel was used more commonly in patients with rhabdomyolysis receiving cerivastatin (17%) than in those receiving atorvastatin (0%, OR infinity; 95% CI = 5.2-infinity). Several medications were tested in vitro for their potential to cause drug-drug interactions. Clopidogrel, rosiglitazone, and montelukast were the most potent inhibitors of cerivastatin metabolism. Clopidogrel and its metabolites also inhibited cerivastatin metabolism in human hepatocytes. These epidemiological and in vitro findings suggest that clopidogrel may cause clinically important, dose-dependent drug-drug interactions with other medications metabolized by CYP2C8. PMID:22419147
