A new study has found a surge in psychosis and schizophrenia among young adults in Canada who use cannabis.

Cannabis-linked schizophrenia cases nearly tripled from 2006 to 2022, with young men ages 19 to 24 facing the highest risk. The increase coincided with the legalization of cannabis in Ontario, Canada, in October 2018.
