The status of hepatitis C virus infection among people who inject drugs in the Middle East and North Africa
Half of people who inject drugs in the Middle East and North Africa appear to have been infected with hepatitis C virus, with large variations in antibody prevalence among countries.
Effect of alcohol use disorders and alcohol intake on the risk of subsequent depressive symptoms: a systematic review and meta‐analysis of cohort studies
Alcohol use disorders are associated with increased the risk of subsequent depressive symptoms. Heavy drinking does not significantly predict occurrence of depressive symptoms after adjusting for potential confounders.
Titrated baclofen for high‐risk alcohol consumption: a randomized placebo‐controlled trial in out‐patients with 1‐year follow‐up
Baclofen was more effective than placebo in reducing alcohol consumption to low‐risk levels but had more, and more serious, adverse events than placebo.
Relationships between US state alcohol policies and alcohol outcomes: differences by gender and race/ethnicity
The effects of beverage‐specific taxes and alcohol availability policies may vary across subgroups, highlighting the importance of considering differential policy impacts in future research and interventions.
Toxic trade: the impact of preferential trade agreements on alcohol imports from Australia in partner countries
Preferential trade agreements involving Australia have been positively associated with alcohol imports from Australia in countries with low rates of alcohol consumption.
Using contributing causes of death improves prediction of opioid involvement in unclassified drug overdoses in US death records
In modeling opioid involvement in unclassified drug overdoses, statistical models with decedent characteristics and contributing causes of death as predictors provide highest predictive accuracy.
Perceptions of extended‐release buprenorphine injections for opioid use disorder among people who regularly use opioids in Australia
Among regular opioid users in Australia, perceptions of extended‐release buprenorphine as a good treatment option are associated with being female, recent illicit drug use and factors relating to the (in)convenience of current opioid agonist treatment.
Self‐reported exposure to, perceptions about, and attitudes about public marijuana smoking among US adults, 2018
While one in four US adults report recent marijuana second‐hand smoke exposure, a majority believe marijuana second‐hand smoke is harmful and oppose public marijuana smoking.
Behavioral couples therapy versus cognitive behavioral therapy for problem gambling: a randomized controlled trial
Differences in the efficacy of internet‐based behavioral couples therapy and cognitive behavioral therapy for treatment of problem gambling were not significant, but more gamblers started treatment in the couples therapy group.
Effect of increasing the delivery of smoking cessation care in alcohol and other drug treatment centres: a cluster‐randomized controlled trial
Integrating smoking cessation treatment into addiction services did not significantly improve short‐term abstinence from smoking.
Nicotine replacement therapy sampling for smoking cessation within primary care: results from a pragmatic cluster randomized clinical trial
Providing smokers with a free 2‐week starter kit of nicotine replacement therapy increased quit attempts, use of stop smoking medications and smoking abstinence compared with standard care in a primary care setting.
