I thought this shit was bangin: http://www.neurophys.wisc.edu/~cozzi/maps4-4-93.html i mean i guess everybody knows that water filters take alot of the bad shit out, and THC is not water soluble.. but its nice to read some studys.. its nice to know you can smoke without alot of health risk.. i hate how people try to say that weed is like smokin an entire pack of cigs.. i guess it could be true but i kinda think its bs.. anyway.. im gonna float away now. peace
