Bath salts are powerful stimulants. Because these drugs are new and some of their contents are unknown, their use presents many dangers. Many of these chemicals are sold over the Internet, in convenience stores, and in 'head shops.' Bath salts may be sold as white or brown crystalline powder in small plastic or foil packages labeled 'not for human consumption."
Mephedrone and MDPV (3-4 methylene-dioxypyrovalerone) are chemicals from a group called cathinones, most commonly found in 'bath salt' products. Users may call them by names such as blizzard, blue silk, charge+, ivory snow, ivory wave, ocean burst, pure ivory, purple wave, snow leopard, stardust, vanilla sky, white dove, white knight and white lightning.
