okay i have done them 3 times, 2 times i had fun and had some good visuals, and the one time i was at a party and i freaked out and hid under a bed for 3 hours crying ... serioulsy dont do that shit around lots of loud people, oh and as for how bad for you they are pretty bad for you if you do them alot, but you build up a tolerance for them really fast so you cant do them very much, they arnt addictive at all really, and here we get an 8th for 20$
