A new study shows teens who admit to using marijuana are at a higher risk of developing psychotic disorder.

The study showed when compared to those who reported not using cannabis during adolescence, the ones who admit to cannabis use were more likely to be hospitalized or to visit an emergency room related to psychotic disorder.
