A study at Columbia University Mailman School of Public Health and The City University of New York has found that the rates of cannabis use and daily cannabis use have increased across the U.S., and that current cannabis use and daily use are substantially higher among individuals residing in states that have legalized recreational cannabis use, relative to those where cannabis use remains illegal. The study also found that rates of cannabis use are even higher among Americans 12 and older who smoke cigarettes, and who reside in states with recreational cannabis laws, compared to those who live in states where cannabis was illegal in 2017.
