— synthetic drugs chemically related to cathinone, a stimulant found in the khat plant. Khat is a shrub grown in East Africa and southern Arabia, and people sometimes chew its leaves for their mild stimulant effects. However, when variants of cathinones are synthetic, the effects can be much stronger and more dangerous. So if you are using bath salts in your bath, they are harmless and can be wonderful for the skin. But if bath salts are used as a stimulant, they can be extremely dangerous and addictive. In fact, drugabuse.gov ranked bath salts 4th in a list of the top ten most abused drugs in 2017.
Bath salts are typically swallowed, smoked, injected, or snorted and dangerously, their effect on the brain is still largely unknown. However, we do know that the effect of bath salts on the brain is similar to cocaine -but is at least 10 times more powerful! Bath salts can produce effects such as: paranoia, nosebleeds, increased sex drive, hallucinations, increased sociability, and panic attacks. In some cases, abusing bath salts has resulted in death. Further, although behavioral therapy has been used to treat addiction to bath salts, there is currently no medication available to treat this addiction.
