March 20, 2019

Smoking weed daily quintuples users' chance of developing psychosis, according to the largest study to ever examine the impact of marijuana on psychotic-disorder rates. And the risk is especially pronounced if the pot is particularly potent. “If you decide to use high-potency marijuana, you should bear in mind: Psychosis is a potential risk,” the study's lead author, Dr. Marta Di Forti of King’s College London, told the AP, which notes that psychosis includes bouts with delusion and hallucination.
