Well... the effects you described are indeed very unusual for weed, no matter how potent it can be... and as you said the weed smelled "different", it seems it was laced indeed.
I know its the usual thing people says when hear about stories like this... "the weed was laced"... mostly it was not, it was just some good weed... but the effects you described are in fact much like the effects of PCP (which is the most common thing used for lacing weed).
I would suggest you to look at the link below... maybe youll find some interesting info there... and maybe the answers you need.

NOTE: Please mods be sensible and dont take this as "other drug talk"...

BTW, the bad feelings you get when remember this are into your mind. I know its hard to fight against our own mind, but if you really wish, you can overcome them... and be able to smoke again... so, good luck! :thumbsup:
