i agree with most the guys here. 1, just chill, try and keep your head about you, if you get a funny feeling later on, don't thikn to yourself you're dying at the dinner table, just take a deep breath and just wait till it passses, you'll be fine.

secondly, worst bad trip i've ever seen for real from smoking jsut weed, well it basically brought on a bad case of claustrophobia and thought atht eh walls were closing, that was it, passed after some fresh air and water. definately sounds like there was some magic additive in with that joint, be it pcp or whatever
