Thankyou for the support everyone. I really dont think the pot was laced or treated with anything. I work with one of the guys i smoked with and he is fine. I will find out from him if the other ppl who we shared the joint with are ok too. It might be that the marijuana was simply too stong for me, and that i took too many hits. (I can count on one hand the number of times i have smoked) In either case, that was the last time i will ever smoke pot.
