Again, strong selection bias, but yes. THC stays in your system for a long time. It can take a while to figure out if the issue is a primary psychotic disorder, like Schizophrenia, that has been exacerbated by THC or if it's only drug-induced. I occasionally see cases that appear to be completely accounted for by THC, but at a far lower rate than meth-induced psychosis.
