Social housing conditions influence morphine dependence and the extinction of morphine place preference in adolescent mice.
Adolescent opioid abuse is on the rise, and current treatments are not effective in reducing rates of relapse. Our previous studies demonstrated that social housing conditions alter the acquisition rate of morphine conditioned place preference (CPP) in adolescent mice. Specifically, the acquisition rate of morphine CPP is slower in morphine-treated animals housed with drug-naïve animals. Thus, here we tested the effect of social housing conditions on the development of morphine dependence and the extinction rate of an acquired morphine CPP. ⋯ Social housing conditions modulate morphine dependence and the extinction rate of morphine CPP. Extinction testing is relevant to human addiction because rehabilitations like extinction therapy may be used to aid human addicts in maintaining abstinence from drug use.

Randomized Controlled TrialHepatotoxicity in a 52-week randomized trial of short-term versus long-term treatment with buprenorphine/naloxone in HIV-negative injection opioid users in China and Thailand.
Buprenorphine/naloxone (BUP/NX), an effective treatment for opioid dependence, has been implicated in hepatic toxicity. However, as persons taking BUP/NX have multiple hepatic risk factors, comparative data are needed to quantify the risk of hepatoxicity with BUP/NX. ⋯ Over 52-week follow-up, the risk of hepatotoxicity was similar in opioid injectors receiving brief and prolonged treatment with BUP/NX. These data suggest that most hepatotoxic events observed during treatment with BUP/NX are due to other factors.

ReviewA meta-analysis of ear-acupuncture, ear-acupressure and auriculotherapy for cigarette smoking cessation.
This systematic review evaluated the effects of ear acupuncture, ear acupressure and auriculotherapy for cigarette smoking cessation (SC) at end-of-treatment (EoT), three, six and 12 months follow-up. ⋯ Pool 1 data appeared most consistent for studies of ear acupressure (EAPR) vs. non-specific EAPR controls, with confirmed SC rates at 3 months post-treatment of 20.0% for test groups vs. 7.5% for controls. In Pool 2 the EAP/R interventions appeared neither inferior nor superior to the behavioural interventions at 3 and 6 month follow-ups. However, meta-analysis results derived from relatively small-sized trials with no biochemical validation of SC in Pool 2. Larger, well-controlled studies using biochemical confirmation of SC are needed.

Patterns of concurrent substance use among nonmedical ADHD stimulant users: results from the National Survey on Drug Use and Health.
To examine patterns of concurrent substance use among adults with nonmedical ADHD stimulant use. ⋯ Nonmedical users of ADHD stimulants are a heterogeneous group with a large subgroup with low prevalence of problematic use of other substances. These subgroups have distinct patterns of mental health comorbidity, behavior problems and service use, with implications for prevention and treatment of nonmedical stimulant use.

The purpose of the present study was to examine the motivations underlying the use of buprenorphine outside of therapeutic channels and the factors that might account for the reported rapid increase in buprenorphine misuse in recent years. ⋯ The non-therapeutic use of buprenorphinehas risen dramatically in the past five years, particularly in those who also use heroin. However, it appears that buprenorphine is rarely preferred for its inherent euphorigenic properties, but rather serves as a substitute for other drugs, particularly heroin, or as a drug used, preferable to methadone, to self-medicate withdrawal sickness or wean off opioids.
