I have been smoking daily for about a year now and i have felt no negative side effects, I use a vapourizer very ocassionally, and the rest is either bubbler or bong, but i eat fairly healthy, work out and play lots of sports.

Im quitting for the summer though, i just bought a half ounce and im beggin it up and only smokin a handful on special occasions, to bad my bong just broke... its good to take a break.

In the fall, ill buy a glass pipe and start over i dont imagine that half o will last very long.
