For those of you not up to date with intravenous drug use news, there are reports of a new drug epidemic in Russia. The drug? Krokodil, or "crocodile" in English, so called because one of the rather nasty after effects of continued use is the user's skin turning green and scaly due to the hydrochloric acid present in the drug. The drug literally eats you away from within, leaving severe skin deformities, brain damage, and sometimes amputations.
Seriously, don't do drugs, kids.
