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.

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.

Pain management perceptions among prescription opioid dependent individuals.
Nearly two-thirds of prescription opioid dependent individuals report chronic pain conditions as both an initial and current motivation for prescription opioid use. However, to date, limited information exists regarding perceptions of the adequacy of pain management and pain management behaviors among prescription opioid dependent individuals with a history of treatment for chronic pain. ⋯ Results highlight the complicated clinical presentation and prevalent perception of the under-treatment of pain among this population. Findings underscore the importance of interdisciplinary approaches to managing the complex presentation of chronic pain patients with comorbid prescription opioid dependence. Implications for future research are discussed.

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.

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.
