I do belive in Pot-Induced-Psycosis, cuz I think I may have or had it. It could also be you just causing it in your head. But I do belive its real because Pot is a psychedelic drug, and some people may not "come back" from it to how they were before. Also thats bull shit bout that anti-social behavior thing, sure pot may make you become a deeper thinker, but common when your high you will talk as long as there is someone to listen, plus you always want people to be laughing while your stoned cuz then you laugh your ass off. Pot has made me more social, and have a better outlook on life, and just generally have a better time enjoying life. Althought the better outlook could also be because of the Extacy.
