an already weakened mind is the only way pot can cause schizophrenia.

schizophrenia may show physical signs that it is there, but it is not induced by outside forces. your brother was previousely mentally unstable before he started smoking pot.
Stoner Shadow Wolf Reviewed by Stoner Shadow Wolf on . Does weed cause heart problems? I have been smoking for 2 years and a bit, and i was wondering if weed, actually contains the same heart problems agents as ciggarettes do. Sometimes after i hit up a huge sess, my heart aches, its not like a sharp pian, but rather an ache, like you'd get in your stomach, any idea what could be causing this? Probably lack of oxygen circulating the the heart(oh wait, can't that turn into a heart attack?) Rating: 5
