Psychoactive bath salts (PABS) are a designer drug of abuse that has led to reports of dangerous intoxication from emergency departments across the US. "Bath salts" are not a hygiene product, as the name might imply. "Bath salts" are central nervous system stimulants that inhibit the norepinephrine-dopamine reuptake system and can lead to serious, and even fatal adverse reactions. The most commonly reported ingredient in "bath salts" is methylenedioxypyrovalerone (MDPV), although other stimulants may be present, such as mephedrone and pyrovalerone.1 MDPV is of the phenethylamine class and is structurally similar to cathinone, an alkaloid found in the khat plant and methamphetamine. Mephedrone has been reported to have a high potential for overdose.
