chill the f out its pot not pcp you crackhead. obviously if its ur second time smoking dope and your smoking some crystally red-haired shit and entire blunts ur gunna be ripped out of ur face and ur mind is going to play tricks on u.

everything u said was a bad marijuana trip, and yes its possible i've had it before, and a lot worse than that. in my experience, my heart was pounding in my chest and i thought it was gunna stop beating. so chill don't lose ur faith in mj, just don't overdo it. just because you can't OD on it physically(like death) doesn't mean that u can't OD on it mentally, hence a bad trip. esp such a potent form of cannibus.
