The increase in alcohol use, recently reported in JAMA Health Forum, suggests that states that legalize recreational cannabis should also consider targeted public health messaging around alcohol and other policy interventions aimed at mitigating problem drinking.

"Recreational cannabis laws have made cannabis legally accessible to nearly half of U.S. adults, but it has been unclear how this affects the use of other substances, such as alcohol," said senior author Coleman Drake, Ph.D., assistant professor in the Department of Health Policy and Management at Pitt Public Health. "It appears that cannabis use increases the probability that people drink, at least in the three years after legalization."
