buprenorphine and Marijuana-Abuse

Cannabis use is common among opioid-dependent patients, but studies of its association with treatment outcome are mixed. In this secondary analysis, the association of cannabis use with opioid treatment outcome is assessed.. In the main study, participants (n=152) aged 15-21 years were randomized to receive psychosocial treatments and either a 12-week course of buprenorphine-naloxone with a dose taper to zero in weeks 9-12, or a 2-week detoxification with buprenorphine-naloxone. Drug use was assessed by self-report and urine drug screen at baseline and during study weeks 1-12. The association between cannabis and opioid use at weeks 4, 8, and 12 was examined using logistic regression models.. Participants reported a median of 3.0 days (range=0-30) cannabis use in the past month; half (50.3%; n=77) reported occasional use, one-third reported no use (33.1%; n=50), and one-sixth reported daily cannabis use (16.6%; n=25). Median lifetime cannabis use was 4.0 years (range=0-11) and median age of initiation of use was 15.0 years (range 9-21). Neither past cannabis use (age of initiation and use in the month prior to baseline) nor concurrent use was associated with level of opioid use.. Overall, cannabis use had no association with opioid use over 12 weeks in this sample of opioid-dependent youth. While cannabis use remains potentially harmful, it was not a predictor of poor opioid treatment outcome.

Information concerning the association between marijuana use and opioid dependence and its treatment is needed to determine effective clinical guidelines for addressing marijuana use among opioid abusers.. Marijuana use was assessed in 107 people enrolled in treatment for opioid dependence.. Univariate comparisons of marijuana users and non-users and multivariate regression analyses were performed to examine associations between marijuana use and socio-demographic, psychosocial, medical and substance-use variables. The relationship between marijuana use and treatment outcome was also explored in a subset of this sample who received treatment that included buprenorphine detoxification and behavior therapy (N = 79).. Sixty-six per cent of participants were current marijuana users and almost all (94%) continued to use during treatment. Users were less likely to be married than non-users, and more likely to report financial difficulties, be involved in drug dealing and engage in sharing of needles (p < 0.05). A unique effect of marijuana use on drug dealing and sharing needles was retained after statistically controlling for the influence of heroin and alcohol use and other socio-demographic variables. No significant adverse relations were observed between marijuana use and treatment outcome.. Pending a more comprehensive understanding of the function and consequences of marijuana use on psychosocial functioning, it appears that progress in treatment for opioid dependence can be made without mandating that patients abstain from marijuana use.

COVID-19 has exacerbated income inequality, structural racism, and social isolation-issues that drive addiction and have previously manifested in the epidemic of opioid-associated overdose. The co-existence of these epidemics has necessitated care practice changes, including the use of telehealth-based encounters for the diagnosis and management of opioid use disorder (OUD).. We describe the development of the "Addiction Telehealth Program" (ATP), a telephone-based program to reduce treatment access barriers for people with substance use disorders staying at San Francisco's COVID-19 Isolation and Quarantine (I&Q) sites. Telehealth encounters were documented in the electronic medical record and an internal tracking system for the San Francisco Department of Public Health (SFDPH) COVID-19 Containment Response. Descriptive statistics were collected on a case series of patients initiated on buprenorphine at I&Q sites and indicators of feasibility were measured.. Between April 10 and May 25, 2020, ATP consulted on the management of opioid, alcohol, GHB, marijuana, and stimulant use for 59 I&Q site guests. Twelve patients were identified with untreated OUD and newly prescribed buprenorphine. Of these, all were marginally housed, 67% were Black, and 58% had never previously been prescribed medications for OUD. Four self-directed early discharge from I&Q-1 prior to and 3 after initiating buprenorphine. Of the remaining 8 patients, 7 reported continuing to take buprenorphine at the time of I&Q discharge and 1 discontinued. No patients started on buprenorphine sustained significant adverse effects, required emergency care, or experienced overdose.. ATP demonstrates the feasibility of telephone-based management of OUD among a highly marginalized patient population in San Francisco and supports the implementation of similar programs in areas of the U.S. where access to addiction treatment is limited. Legal changes permitting the prescribing of buprenorphine via telehealth without the requirement of an in-person visit should persist beyond the COVID-19 public health emergency.

To test if polysubstance use profiles and drug-related outcomes differ between those receiving and not receiving opioid substitution therapies (OST) among people who inject drugs (PWID).. An annual cross-sectional, sentinel sample of PWID across Australia.. Data came from 3 years (2011-13) of the Illicit Drug Reporting System (IDRS).. A total of 2673 participants who injected drugs from the combined national IDRS samples of 2011 (n = 868), 2012 (n = 922) and 2013 (n = 883).. Latent class analysis (LCA) was used to summarize participants' self-reported use of 18 types of substances, with the resulting polysubstance use profiles then associated with participant experience of a number of drug-related outcomes.. Polysubstance use profiles exhibiting a broad range of substance use were generally at increased risk of negative drug-related outcomes, whether or not participants were receiving OST, including thrombosis among OST receivers [odds ratio (OR) = 2.13, 95% confidence intervals (CI) = 1.09-4.17], injecting with used needles among OST receivers and non-receivers, respectively (OR = 2.78, 95% CI = 1.50-5.13; OR = 2.15, 95% CI = 1.34-3.45) and violent criminal offences among OST receivers and non-receivers, respectively (OR =2.30, 95% CI = 1.16-4.58; OR = 1.87, 95% CI = 1.14-3.07). An important exception was non-fatal overdose which was related specifically to a class of PWID who were not receiving OST and used morphine frequently (OR = 1.83, 95% CI = 1.06-3.17) CONCLUSION: Regardless of opioid substitution therapies usage, people who inject drugs who use a broad-range of substances experience greater levels of injecting-related injuries and poorer health outcomes and are more likely to engage in criminal activity than other groups of people who inject drugs.

Illicit use of methadone and buprenorphine has been described as a growing problem in Sweden in recent years, and has been associated with an increased drug-related mortality. Critics claim that the substances have become popular among adolescents and that they function as a gateway to heroin use. The aim of this study is to investigate, firstly, the extent to which illicit use of methadone and buprenorphine occurs among adolescents and young adults in Sweden, and secondly, at what stage in a user's drug career these substances tend to appear.. The study is based on surveys and structured interviews on drug use among various populations of young people, in addition to qualitative interviews with 86 informants who, in their professional capacity, encounter adolescents or young adults who are using illicit drugs.. Illicit use of methadone and buprenorphine is rare among young people in Sweden. According to high school surveys, less than 0.1% have tried these substances. Among young drug users in general, few have tried the substances, and there is nothing to indicate that they act as gateway drugs. Among adolescents and young adults with severe drug problems, however, the illicit use of methadone and buprenorphine is more common (54% in a compulsory care sample). These substances normally enter the drug career late, and few use them as their main drug of choice. Other prescription drugs, like benzodiazepines and tramadol, are used by adolescents to a far greater extent. Diversion and illicit use of methadone and buprenorphine is not seen as a serious problem by the professionals interviewed. A general view is that the substances are mainly used by people with a heroin or polydrug addiction, often for "self-medication" purposes. However, several informants express concern that methadone and buprenorphine may cause fatalities among young drug users without an opioid tolerance.. Illicit use of methadone and buprenorphine among young drug users is not a widespread problem in Sweden. Harm-reduction measures should target drug users with more severe problems, among whom illicit use of methadone and buprenorphine is more common and pose a medical risk. Illicit use of other prescription drugs, which are less controlled and more widely used by young people, is an important issue for further research.

conduct needs assessments and treatment compliance evaluations in MMT and Suboxone Substitution State Programs in Georgia (Republic of). 506 patients (2 females) were surveyed (92% on Methadone, 8% on Suboxone) from 6 Tbilisi and 4 regional State Programs in 2011 November. Mean age - 40±8,56 (22-65) year; 254 (51.4%) were in treatment for 1-3 year. Evaluation was carried out on the base of structured self-questionnaire that covers demographics, drug use history, general drug use trends, psychotherapeutic sessions' acceptance and open label question regarding treatment challenges and satisfaction. 305 (60.3%) attended individual and 57 (11.3%) group psychotherapy sessions with 50.79% attending once/month or rare. The main reason given for therapy non-attendance - no needs for it (29.48%); the main drugs before admission - heroin (80.04%), buprenorphine (53.49%); Main drugs used in Georgia nowadays - desomorphine ("crocodile"), alcohol and marihuana. Commonly used drugs by program patients (136 positive answers) - alcohol-13.62%, marihuana-10.39%, pregabalin - 8.17%, opioids- 6.62% (mostly-"crocodile"), home-made stimulants-6.23%, sedatives -5.45%. 55.4% are extremely satisfied with treatment, 82.4% - with program staff. Patients' main wishes- free of charge programs (46.4%) and provide take-home doses (22.07%). Methadone and Suboxone ST are being well accepted in Georgia and appear to be reducing illegal opioid use. However, the psychotherapeutic sessions' attendance is very low.

This study of a cohort of drug addicts receiving buprenorphine maintenance treatment in a district in western France focused on changes in their drug use and their social and work lives. It also looked at the health consequences of their drug use before and after maintenance treatment (mean: four years).. From the files of an agency providing services to drug addicts, we randomly selected 180 of the 236 patients receiving buprenorphine maintenance treatment (BMT). Usable questionnaires were returned by 118 subjects (66% response rate). This self-administered questionnaire included 32 items.. The respondents accounted for half the population receiving drug maintenance treatment and were representative of the population for age and sex. The mean age was 30 +/- 5 years, mean BMT dose 6,5 mg/day, and mean duration of drug maintenance treatment 47 +/- 27 months. Other drug use diminished during the four years of maintenance treatment: three of every four heroin users had stopped, opiate users dropped from 31% to 5% of the population, and cocaine use followed a similar trend. Benzodiazepine use also fell, but remained relatively frequent (27%, compared with 68% four years earlier). Drinking patterns changed from strongly alcoholic beverages to lower-proof drinks. Arrest rates dropped from 70% to 25%. The percentage of persons seropositive for HIV (4%) and HCV (33%) remained low, but too many subjects had not been screened (35%). Roughly 10% of these subjects had returned to work, mainly those who had cut their drug use most.. While our survey reveals some positive points, especially a reduction in illegal drug use, several negative observations appeared, including combined use of cannabis and benzodiazepines, inadequate screening, and misuse of BMD. These results underline how important it is for care providers to focus simultaneously on medical treatment and identification of co-morbidities and to provide social work when necessary. The employment rate remains too low.
