If I have a family history of mental illness is it ok for me to smoke Cannabis?

I'm only going to say that there is significant reason to believe that drug use, including pot can trigger oe exacerbate mental illness in persons whom are predisposed. This according to reliable study.The best advice for someone like you, is to never use recrational drugs, drink in excess, live a relaxed lifestyle, get plenty of rest, and adress emotional upsets early and often by seeking emotional support from friends/family or a therapist. Good luck.
