Soma, as many anthropology majors who did a lot of drugs know, is a divine hallucinogen from India, widely believed to be derived from fly agaric mushrooms. The easiest way to concentrate it for maximum potency is to drink it. And then...drink it again. And again.** After a few runs through t'old urinary tract, it's potent enough to make you see god. However, I have already met a god on drugs, and while he was a pleasant sort, I would require a lot more incentive before drinking recycled Canadian urine.
