However, these findings have important implications for treatment and prevention, particularly in the context of changes in marijuana legalization. In the USA, greater alcohol consumption can only mean increases in traffic fatalities and injuries, violent crime, and all the other negative population-wide outcomes and costs associated with alcohol and marijuana use. Interestingly, in Colorado, where marijuana has been legal for recreational use since 2014, all these negative indicators have been on the rise along with a conspicuous increase in alcohol consumption.

“While marijuana can cause anxiety and paranoia, addiction, decreased cognition, behavioural problems and impaired driving,” doctors said, Trudeau’s promise to legalize it means all they can do is try to persuade him to anticipate future health costs, introduce measures to protect public safety, and ensure there is appropriate surveillance of consequences.
