Actually, the 'Bath Salts' crisis has been ramping up significantly in ERs 'everywhere'. That's one intentionally-mislabeled name this stuff is sold under. This stuff is sold legally at Convenience Stores and Truck Stops. A person seriously overheats, and becomes extremely delusional. Symptoms return once Detox is tried using the 'usual' calming Drugs like Valium. That aspect, alone, has Doctors mystified.
As a Sub Teacher in Health, my Wife and I try to stay up on these developments in a casual manner. See 2 Links that explain what's going on - IMO - and edited Video of the actual attack that is not gruesome. Everything occurring - including the 'casual' response of folks passing by - is caught on Tape. FWIW, this Video is from the Site of a major Newspaper. I consider it factual, rather than sensational, since most all the event is behind a Bridge Support. Otherwise, I would not post this Link.
