you missed the point, but its ok.
show me the formula that says Brain + Weed = Psychosis and then we can talk until then have a nice day
I didn't miss the point at all mate. I think you struggle with reading comprehension -but you're probably high, so it's ok. Marijuana is linked to increased risk of psychosis and drug-induced psychosis exists.
As for your silly little formula, you are asking for something that nobody can provide, and it doesn't make you clever.
It's true that we can't definitively 'prove' that in each individual case that a psychotic break was 'caused' by marijuana. We just know that somebody abusing it is more likely to experience one. However, mental health practioners - not being retards - will treat somebody who has no history of mental illness, but is abusing drugs, and suddenly has a psychotic break as having drug-induced psychosis, even if it's possible that the two phenomena are unrelated.
You should read up on this basic science rather than making inane points to some other dipshit on an MMA forum.
