Props to all you junkies who "clean"ed up their act - it takes a lot of willpower that few people are able to muster up.
I had a run in with weed that seems similar to what Falcon describes - quite frightening.
A friend of mine who has been a druggy for most of his life, turned 39 some time ago, had a likewise experience with weed... he said "After all the LSD and other shit I've taken it was smoking too much [of it] that nearly made me run to my parents because I was in such an extreme state of paranoia and fear."
