Most of the psychotic episodes that I have personally responded to that were triggered by marijuana use were from marijuana that was eaten not smoked. Is that the “delivery method you were thinking of?
Other “delivery methods” of ingesting mj can easily lead to ODs as people, and not uncommonly, children, have no idea how much THC content of the brownies/gummy bears/etc.
Funny thing about the psychotic episodes - well, two funny things. DMOTMC (Devout Members Of The Marijuana Cult) claim that people who get psycho from mj would have been psycho anyway, that’s one. The other is that some people (a not inconsiderable number) don’t recover from mj induced or triggered psychosis. Or even not full on nutz, but bouts of paranoia and other fun stuff.
