Hey everyone, I want to know more about psychosis and mental issues caused by mdma because my brother recently had a psychosis after about 7 years of drugs usage. He mainly smoked weed for those 7 years, but I know he also did many drugs such as E, speed, shrooms and salvia. I don't know how often he used these drugs, except for pot which he used on a daily basis most of the time. Note that my parents said they noticed he had mental health issues before he started using any drugs.
So my question is: Can rare usage(1-2 times a year) of ecstasy can cause psychosis or other serious mental health issues?
I consider my actual mental health to be OK, and I smoke pot couples times a week and did E twice. I'm thinking about taking E at an EDM festival this summer but I really hesitate because of what hapenned to my brother. Also, I talked to a cop about my brother and according to him drugs like ecstasy really fucks up your mental health and can causes psychosis (I know he probably knows nothing about it and just said that because he's against drugs, but it still made me think).
