AI Article Synopsis
- Alcohol and cannabis are the leading intoxicants found in fatal car accidents, and both increase the risk of collisions.
- Research reviews how these substances impact simulated driving performance and their effects on breath alcohol and THC levels.
- The study concludes that using alcohol and cannabis together worsens driving abilities, cognitive function, and alters the subjective experience of the drugs.
Article Abstract
Alcohol and cannabis are the two most commonly found intoxicating substances in fatally injured drivers. Epidemiological studies have demonstrated that the use of alcohol or cannabis can lead to an increase in the risk of a motor vehicle collision. Reducing the risks associated with driving under the influence of alcohol or cannabis is achieved partly through roadside detection of breath alcohol concentrations (BrAC) or blood delta-9-tetrahydrocannabinol (THC) levels. The purpose of the present review is to compile the laboratory studies on the combined effects of alcohol and cannabis on simulated driving as well as those evaluating combinations of these drugs on BrAC or blood THC. Given that driving can be affected by a number of cognitive processes, the literature on the cognitive effects of combinations of alcohol and cannabis is also reviewed, along with a discussion of a potential additive effect on the subjective qualities of these drugs. In sum, it is concluded that alcohol and cannabis have additive effects on driving skills, cognition and subjective effects. (PsycInfo Database Record (c) 2022 APA, all rights reserved).

Validity, reliability and clinical utility of ASSIST-Y in assessing risk of substance-related harm and dependence in Spanish male adolescents.
Child Adolesc Psychiatry Ment Health

School of Biomedicine (Pharmacology), The University of Adelaide, Adelaide, Australia.
Background: Substance use among adolescents is strongly associated with adverse physical, mental health, and social outcomes. Prevention and early intervention can reduce the likelihood of future problems, but requires valid and reliable screening tools capable of assessing risk across a range of substances. This study assessed the validity, reliability, and clinical utility of the Alcohol, Smoking and Substance Involvement Screening Test (ASSIST-Y) for adolescents aged 15-17 years.

Department of Psychological and Brain Sciences, University of Louisville.
Objective: Previous research has found that momentary positive affect precedes alcohol use, whereas results have been more mixed for negative affect.
Method: This study replicates and builds upon this literature by using a heavy drinking sample, half lesbian, gay, bisexual, trans, queer/questioning, and other minoritized sexual and gender identities (LGBTQ+) individuals.
Results: This study found that positive affect was related to subsequent alcohol use, but the relation was weaker for LGBTQ+ individuals compared to cisgender-straight individuals.

Objective: To identify whether mental health wellbeing, age, gender or recent substance use pattern affected completion rates of a dual diagnosis inpatient program.
Method: This retrospective cohort study reviewed medical records of patients admitted between October 2018 and December 2021 of Westside Lodge, a dual diagnosis inpatient program. Demographic information, mental health screening tool results (BASIS-24) and self-reported substance use data were accessed from the patients' electronic medical records.
