I bet it was a combination of things, probably it was extremely good weed, possibly laced but probably not if no one else felt those crazy effects, and I think the reason that you still experienced things long after, and since the neurologist couldn't find anything wrong, its probably psychological. The fact that the smell of the smoke triggers the feeling is a perfect example of classical conditioning. A psychologist could possibly help if you know one, maybe he could help you get back to smoking the herb once again. :rastasmoke:
