Marijuana legalization is associated with decreased use of alcohol, nicotine and non-prescription opioids among young adults, according to a new study.

Researchers at the University of Washington analyzed data on substance use trends from 2014 to 2019, finding that people aged 21-25 were less likely to consume the arguably more dangerous drugs post-legalization in the state.

The study [...] analyzing data from 12,694 adults.

“Contrary to concerns about spillover effects, implementation of legalized nonmedical cannabis coincided with decreases in alcohol and cigarette use and pain reliever misuse,” the study abstract said.
