Ten year’s worth of data from a survey of American college students with 1.1 million participants shows that of-age students are less likely to binge drink where recreational cannabis is legal. That’s according to a new study just published in Addictive Behaviors, one of the first to investigate how university students’ substance consumption changes after states legalize recreational marijuana. Researchers have already detected trends of increased cannabis consumption among college students after legalization. But this new study suggests that students are substituting cannabis for alcohol and binge drinking less often as a result.
Recreational Marijuana Legalization Decreased Binge Drinking Among Of-Age College Students
In a newly published study, researchers examine trends in college students’ alcohol, nicotine, prescription opioid and other drug use after recreational marijuana legalization. Using data from surveys of American university students from 2008 to 2018, researchers wanted to see how recreational marijuana legalization (RML) impacts other substance use trends.
The study highlights how RML was linked to decreased binge drinking prevalence among university students old enough to legally consume alcohol. After states legalize recreational weed, researchers observed a decrease in college binge drinking by an average of 6 percent.
