oh yeah, i have gotten waaay too high a time or two.
when i was newer to smoking i had cotton mouth so bad i thought i was going to die. i felt like my head was dehydrating.
and then once i kept laughing so long and hard that i couldnt breath and passed out due to lack of oxygen.
and another time i pissed on myself because i didnt realize that that feeling i was having ment i had to pee.

so yeah, i have been pretty damn stoned off my rocker.

since i have started smoking more regularly i dont get so far gone. but more recently i got too high, and i was walking around... everything looked like it was in a flip book... all choppy looking.

i have been more out of it than this by far but not on MJ
