New Study Reveals Cannabis Can Reduce Heavy Drinkers’ Consumption by Nearly 30%
A recent study published in the American Journal of Psychiatry has found that heavy drinkers who use cannabis can reduce their alcohol consumption by nearly 30%. The study, conducted by researchers at Brown University’s Center for Alcohol and Addiction Studies, involved 157 adults between the ages of 21 and 44 who reported heavy drinking and regular cannabis use.
The participants were randomly assigned to one of three groups: those who smoked cannabis with a high level of THC (7.2%), those who smoked cannabis with a lower level of THC (3.1%), and a control group that received a placebo. The participants were then given the choice to drink alcohol or accept a cash payment.
The results showed that those who smoked cannabis with the higher level of THC consumed about 27% less alcohol than those who smoked a placebo. They also reported an immediate reduction in the urge to drink. Those who smoked cannabis with the lower level of THC consumed about 19% less alcohol.
The study’s lead author, Jane Metrik, Ph.D., noted that the findings suggest that cannabis may not exert a uniform effect on alcohol motivation, and that other mechanisms may also explain how cannabis impacts subsequent alcohol use.
While the study’s results are promising, the researchers emphasized that the long-term effects of cannabis use on alcohol consumption are still unknown. They also noted that the study’s sample consisted of individuals who used cannabis nearly every day, so those who use cannabis less often may show different alcohol-related behaviors.
Experts weigh in on the study’s findings, with some praising the study’s rigorous design and others cautioning that more research is needed to fully understand the effects of cannabis on alcohol use.
The study’s findings align with the “California sober” trend, where smoking cannabis may be a way to reduce other substance use. However, the long-term effects of cannabis use on alcohol consumption are still unknown, and more research is needed to fully understand the effects of cannabis on alcohol use.
In the meantime, the study’s lead author recommends that individuals who are substituting cannabis for alcohol closely monitor their use and be aware of the risk of cannabis use disorder. She also encourages them to consider evidence-based alcohol treatments.
