Cannabis-vaping entails relevant but probably varied effects for public health: it may reduce certain cannabis use-related health risks, but entice cannabis-naive individuals into use due to "cleaner" imagery. Improved evidence is needed to guide informed and differentiated policies for cannabis-vaping, which emphasizes the urgent need for public health-based cannabis regulation.

To calculate the alcohol-attributable fraction (AAF) of injury morbidity by volume of consumption prior to injury based on newly reported relative risk (RR) estimates. ⋯ Alcohol-attributable injuries presenting in emergency departments are higher for males than females, for violence-related injuries compared with other types of injury, and for countries with more detrimental drinking patterns compared with those with less detrimental patterns.

Randomized Controlled Trial Multicenter Study
Project QUIT (Quit Using Drugs Intervention Trial): a randomized controlled trial of a primary care-based multi-component brief intervention to reduce risky drug use.
To assess the effect of a multi-component primary care delivered brief intervention for reducing risky psychoactive drug use (RDU) among patients identified by screening. ⋯ A primary-care based, clinician-delivered brief intervention with follow-up coaching calls may decrease risky psychoactive drug use.

The proliferation of vaporization ('vaping') as a method for administering cannabis raises many of the same public health issues being debated and investigated in relation to e-cigarettes (e-cigs). Good epidemiological data on the prevalence of vaping cannabis are not yet available, but with current trends towards societal approval of medicinal and recreational use of cannabis, the pros and cons of vaping cannabis warrant study. As with e-cigs, vaping cannabis portends putative health benefits by reducing harm from ingesting toxic smoke. ⋯ Sales and marketing of vaping devices with no regulatory guidelines, especially related to advertising or product development targeting youth, parallels concerns under debate related to e-cigs and youth. Thus, the quandary of whether or not to promote vaping as a safer method of cannabis administration for those wishing to use cannabis, and how to regulate vaping and vaping devices, necessitates substantial investigation and discussion. Addressing these issues in concert with efforts directed towards e-cigs may save time and energy and result in a more comprehensive and effective public health policy on vaping.

Randomized Controlled Trial
Effect of reducing the nicotine content of cigarettes on cigarette smoking behavior and tobacco smoke toxicant exposure: 2-year follow up.
A broadly mandated reduction of the nicotine content (RNC) of cigarettes has been proposed in the United States to reduce the addictiveness of cigarettes, to prevent new smokers from becoming addicted and to facilitate quitting in established smokers. The primary aim of this study was to determine whether following 7 months of smoking very low nicotine content cigarettes (VLNC), and then returning to their own cigarettes, smokers would demonstrate persistently reduced nicotine intake compared with baseline or quit smoking. ⋯ In smokers not interested in quitting, reducing the nicotine content in cigarettes over 12 months does not appear to result in extinction of nicotine dependence, assessed by persistently reduced nicotine intake or quitting smoking over the subsequent 12 months.
