Students Who Up Their Cannabis Use Face Increased Risk of Alcohol Problems
Cannabis use can worsen some consequences of alcohol use among young adult drinkers over time, according to a new study which tracked the frequency of cannabis use and negative drinking outcomes among college students over three years. More than one in five young drinkers use cannabis, often (but not always) at the same time as drinking alcohol. This is a concern because the effects of cannabis might combine with those of alcohol to increase negative outcomes of drinking, such as impaired driving or developing an alcohol use disorder Although previous research has suggested a link between cannabis use and alcohol consequences, there have been few long-term evaluations of the impact of fluctuations in cannabis use on alcohol consequences over time. The latest study, published in the journal Alcoholism: Clinical and Experimental Research, was conducted by researchers in Toronto, Ontario, and Buffalo, New York.
