i've seen people do it. i haven't. but it depends on the person.
my friends just start laughing real hard. but don't scare them.
they'll flip and run away.
I've never tried it, don't plan on trying it either. I'm pretty well experienced with most other things besides opiates & the very hard drugs, I've seen this drug turn out to be a very bad experience to a good number of people. More times bad than good, I would honestly say. Pass me my bong and we'll be good.
