Black smokers can quit with a smartphone app

The iCanQuit smartphone application was more effective than a more conventional smartphone application (QuitGuide) at getting Black US adults who smoke to quit and remain abstinent over 12 months.

Brief counselling by a doctor can reduce drinking

A new systematic review and meta-analysis has found that alcohol-targeted brief interventions (short, structured, one-to-one conversations about drinking designed to motivate changes in risky behaviour) delivered in doctors’ offices and similar medical settings can produce small but useful reductions in drinking.

Increasing access to an overdose rescue drug does not reduce perceived risk of opioid use

A new study published in the scientific journal Addiction has found that naloxone access laws in the US have not reduced perceptions of how dangerous heroin use is in the US population.

Tobacco and alcohol may increase likelihood of using illegal drugs, new study shows

The use of legal drugs (tobacco and alcohol) may lead to the use of cannabis, a new study led by the University of Bristol and published in the journal Addiction has found. The study also found evidence that cannabis use may lead to smoking initiation, and opioid dependence could lead to increased alcohol consumption. Additionally, there might be shared risk factors that influence the use of multiple substances.

New review finds non-invasive brain stimulation may reduce smoking

A new systematic review of randomised controlled trials has found evidence that non-invasive brain stimulation may reduce smoking frequency (number of cigarettes per day) in nicotine-dependent smokers.

New meta-analysis finds cannabis may be linked to development of opioid use disorders

A new systematic review and meta-analysis has found that people who use cannabis are disproportionately more likely to initiate opioid use and engage in problematic patterns of use than people who do not use cannabis. But the quality of the evidence for this finding is low.

Alcohol and sexist attitudes combine to increase male violence towards women

In a study of men in low and middle income countries, heavy drinking males were more likely to commit violence against their wives and girlfriends (intimate partner violence, or IPV) if they held sexist rather than egalitarian attitudes about women.

Stop-smoking drug Chantix/Champix does not increase risk of psychiatric problems

A new analysis of data from a randomised controlled trial of the stop-smoking drug varenicline (brand name Chantix in the US and Champix elsewhere), has provided clear evidence that varenicline does not increase the risk of psychiatric problems. The study also assessed the risk of psychiatric problems associated with bupropion and the nicotine patch. It similarly found moderate to strong evidence for no increased risk of neuropsychiatric adverse events relative to use of a placebo.

Ethnic minorities in England less likely to report using e-cigarettes to reduce smoking

Ethnic minority groups may be missing out on a means of reducing smoking. A household survey in England has found it is less common for smokers of Asian, Arab, and other ethnicities to use e-cigarettes to try to reduce their cigarette consumption or when they are not allowed to smoke than those of White ethnicity.
