Brownies or a vaporizer are two easy ways around the toxins you speak of, didn't know it was such a touchy subject. Stress kills more than people think relax man, btw watch out for that fake sugar it'll cause cancer, and that milk will likely cause an allergic reaction, the sugar will cause diabetes, have you ever had your water checked from the tap? Mine has around 300 ppm's worth of crap in it, compared to 0-25 in pure water, and last I checked caffeine,alcohol and cigs are all drugs and legal, I used it to bring my weight back up to par period, I also take a needle in my ass at least weekly/daily so there is no denial of drug use here.
