Then, it was just last week state officials in New Jersey began visiting gas stations and smoke shops to confiscate so-called “bath salts” from store shelves, after the state issued an order making the designer drugs illegal in New Jersey. Lawmakers moved quickly to ban bath salt sales after William Parisio, 22, murdered his girlfriend, Pamela Schmidt, while he was allegedly high on bath salts. The bath salt powder, which can be snorted, smoked or ingested can have effects similar to cocaine or methamphetamines. Users typically experience extreme agitation, paranoia and vivid hallucinations. During the show tonight, Dr. Drew talks to families whose lives were devastated by a loved one’s addiction to bath salts.

Catch it all tonight at 9 p.m. ET/PT on HLN!
