Abusing bath salts

When Neil Brown got high on dangerous chemicals sold as bath salts, he took his skinning knife and slit his face and stomach repeatedly. Brown survived, but authorities say others haven't been so lucky after snorting, injecting or smoking powders with such innocuous-sounding names as Ivory Wave, Red Dove and Vanilla Sky.

Some say the effects of the powders are as powerful as abusing methamphetamine... emergency calls are being reported over-exposure to the stimulants the powders often contain: mephedrone and methylenedioxypyrovalerone, also known as MDPV...

The stimulants aren't regulated by the U.S. Drug Enforcement Administration, but are facing federal scrutiny. Law officers say some of the substances are being shipped from Europe, but origins are still unclear... MDPV and mephedrone are made in a lab, and they aren't regulated because they're not marketed for human consumption...

A small packet of the chemicals typically costs as little as $20.
