I think it might be damaging. Not sure. It really just gets you light headed and high at the same time. If it is real bad let me know lol. I dont know if it is and i have done it at least 100 times this month hahahaWHOA!!!! Sounds fucked up...and maybe a bit damaging if done too many times, but sounds fun a try or 2.
lol, yeah i fall alot. And blacking out is all part of the crocking haha. If you dont black out your not crocking right hahayea when i was smoking with my aunt and it happened to me and i told her "I cant see you right now Im having a head rush" she got all worried and thinks I have epilepsy now lol
