Up to one in four young adults use alcohol and marijuana simultaneously (i.e., use at the same time with overlapping effects), a behavior linked to a greater risk of adverse consequences. Given the expanding legalization of non-medical marijuana use, there is an urgent need to better understand the effects of simultaneous use and who is most vulnerable to adverse outcomes.
Co-existing use of alcohol and cannabis can lead to negative outcomes such as the development of a substance-use disorder, poor academic and occupational performance, and psychiatric disorders when compared to use of either drug alone. New research that examines simultaneous alcohol/cannabis use has found higher levels of drinking after 18 months. These results and others will be shared at the 46th annual scientific meeting of the Research Society on Alcohol (RSA) in Bellevue, Washington.
Not only is cannabis the most commonly used illicit – in a number of states – drug among people who drink alcohol, cannabis is also by far the most commonly used illicit drug in the U.S. overall. New research findings tease out the nuanced relationship between alcohol and cannabis through a survey of regular cannabis users who also report drinking alcohol, as well as heavy drinkers in treatment who also use cannabis. These findings will be shared at the 44th annual scientific meeting of the Research Society on Alcoholism (RSA), which due to the COVID-19 pandemic will be held virtually this year from the 19th – 23rd of June 2021.
