Randomized Controlled TrialAcute and residual effects of smoked cannabis: Impact on driving speed and lateral control, heart rate, and self-reported drug effects.
Although driving under the influence of cannabis is increasingly common among young adults, little is known about residual effects on driver behavior. This study examined acute and residual effects of smoked cannabis on simulated driving performance of young cannabis users. ⋯ Acutely, cannabis caused decreased speed, increased heart rate, and increases in VAS drug effect and drug high. There was no evidence of residual effects on these measures over the two days following cannabis administration.

Randomized Controlled TrialA randomized controlled trial evaluating integrated versus phased application of evidence-based psychotherapies for military veterans with comorbid PTSD and substance use disorders.
Recent clinical practice guidelines recommend the delivery of evidence-based psychotherapies for both substance use disorder (SUD) and posttraumatic stress disorder (PTSD) within the same treatment episode for patients with SUD/PTSD comorbidity. This randomized clinical trial evaluated the comparative effectiveness of integrating versus phasing evidence-based psychotherapies for SUD and PTSD among veterans with co-occurring SUD/ PTSD. ⋯ Our hypothesis that integrated MET/PE would result in better outcomes than phased MET/PE across a range of PTSD and SUD measures was not supported; both strategies for combining two single-disorder treatments for co-occurring SUD/PTSD yielded significant symptom reduction.

Associations between polygenic risk for tobacco and alcohol use and liability to tobacco and alcohol use, and psychiatric disorders in an independent sample of 13,999 Australian adults.
Substance use, substance use disorders (SUDs), and psychiatric disorders commonly co-occur. Genetic risk common to these complex traits is an important explanation; however, little is known about how polygenic risk for tobacco or alcohol use overlaps the genetic risk for the comorbid SUDs and psychiatric disorders. ⋯ Polygenic risks associated with tobacco use are also associated with liability to alcohol consumption, nicotine dependence, and conduct disorder.

Roll-your-own cigarette smoking among youth experiencing homelessness.
Roll-your-own (RYO) cigarette smoking is uncommon among young smokers in the U.S. but may be more widespread among those experiencing homelessness as it is a less expensive source of cigarettes. This study examines the prevalence and correlates of RYO use among young cigarette smokers experiencing homelessness. ⋯ RYOs may encourage continued tobacco use among youth experiencing homelessness and pose additional health risks despite users' beliefs to the contrary. Future research is needed to obtain more detailed information on RYO practices and motivations for use, as well as how to address RYOs in efforts to reduce tobacco use in this population.

Trends in and factors associated with the adoption of digital aids for smoking cessation and alcohol reduction: A population survey in England.
Digital smoking cessation and alcohol reduction aids are widely available in England. To estimate their public health impact, researchers need to consider their adoption in the target population. We assessed adoption rates, and characteristics of adopters, of digital smoking cessation and alcohol reduction aids in England. ⋯ Digital smoking cessation and alcohol reduction aids are rarely used by smokers or high-risk drinkers attempting to quit/cut down in England, indicating that most of the target population is not being reached. Despite overall digital access improving, adoption rates remained similarly low between 2015-2018.
