Psychosis is usually triggered factors like genetics and the environment. Experts say the new study’s findings have implications for jurisdictions legalizing marijuana, warning they should also consider the impact on their psychiatric services.

Experts analyzed data from 11 sites across Europe and Brazil. They found daily marijuana use was more common among people with a new psychosis diagnosis than among those who didn’t smoke pot.

Dr. Marta Fiori, the study’s lead author, said that people smoking high-potency marijuana should know psychosis is a potential risk.
