Shoot you guys, do you all forget that weed is a psychotrophic substance? It acts on the central nervous system and alters brain function, hello, hallucinations aren't out of the norm for some people who smoke. Yes, weed is a hallucinagin, a minor one, albiet, but a hallucinagin none the less. You ever wonder why more people don't smoke? It's because many have adverse reactions like this guy, weed is powerful stuff.
I doubt someone paid the extra dollar and went the extra mile to get PCP and give it to this guy (which has a street nickname of embalming fluid, embalming fluid is actually NEVER used to get anyone high, except maybe by the dumbest teenagers in the world who I bet won't make that mistake again)
Sounds like this guy just has some brain chemical issues that he should be concious of when smoking, and make sure he is always in a place where he can't hurt himself or others if a reaction like that happens again (not driving for example). Ya might want to stop holding in the smoke for such a long time man, not good for ya. I know when I started smoking after 4 years of not, weed was almost too intense and trippy for me to get back into. All you pothead out there, maybe you forget what that first bowl is like after your tolerance is completely gone. It's pretty crazy...
