It is worse than you think. Cocaine quality at the wholesale level is tested chemically, not by experimental use. And, contrary to what the media portrays, from what I have seen, lesbians tend to be not only odd and ugly, but they are usually also souls in torment with dismal personal histories of being victims and generally disliked.
Back in the old days, druggies grabbed up a wino and dose them with LSD to see if it was good, or perhaps test out the batch.
