Young Adults’ Simultaneous Use of Alcohol and Marijuana Linked to More Drinking, More Negative Alcohol Consequences, and More Hours High
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.
Concurrent use of alcohol and cannabis leads to higher levels of drinking in the longer term
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.

Study First to Show Statewide Cannabis-related Deaths in Florida
There has been a 1,107.01 percent increase in the number of people with medical cannabis cards in Florida (2018 to Jan. 27). One key reason is because many people believe cannabinoids – plant derived, medicinal, and synthetic or chemically engineered – are safe to use. A study shows that 386 people died in Florida as a result of cannabis use; of these, 258 cases were caused by synthetic cannabis. Nearly 88 percent were men; 28 percent of deaths were in those ages 45 to 54, compared to 9 percent in those ages 8 to 24. Nearly 99 percent of individuals using cannabis and synthetic cannabis died from accidents.

Study of pre-teens yields surprises about alcohol, tobacco and marijuana
They may only be in 4th or 5th grade, but 1 in 10 pre-teen children already say they’re curious about using alcohol or tobacco products, and 1 in 50 say they’re curious about using marijuana, a new study shows.

About the cannabis and alcohol relationship: it’s complicated
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.
