“A flesh-eating drug that turns people into zombie-like creatures seems to have made its way to the United States.
This extremely addictive injectable opioid is called krokodil (pronounced like crocodile) or desomorphine. It’s so named in part because users report black or green scaly skin as a side effect.
Krokodil causes serious damage to the veins and soft tissue infections, rapidly followed by gangrene and necrosis, according to a 2013 study.”
