What are bath salts?
These are NOT the bath salts you put in your bath. "Street chemists have developed a form of synthetic cocaine/methamphetamine that is sold as bath salts or plant food".  These "Bath Salts" and other new designer drugs have become a way to circumvent the DEA and drug laws. They contain synthetic stimulants which are analogues (drugs formulated by street chemists that are similar to the controlled substance) to their controlled counterparts; Cathinone and Methcathinone. "MDPV is a central nervous system (CNS) stimulant and it was first seized in Germany in 2007. The abuse of MDPV is increasing, particularly in Europe and Australia. MDPV has been identified in products called "bath salts" which are sold on websites based in Europe."  Manufacturers are side stepping drug laws in two ways. First, by the use of primarily two analogues, methy 1-methcathinone (Mephedrone) and methylone dioxy-pyrovalerone (MDPV) along with some of their own synthetic mixture. Second, by packaging these drugs as bath salts or plant food and labeling them as "Not For Human Consumption".
What does it look like?
Bath salts are sold under many different names and brands normally in a small jar or re-sealable foil packet. The substance is usually a crystalline like material that is then crushed into a more powder like form where it can easily be snorted or mixed into a drink. Bath salts can also be smoked in a glass pipe like methamphetamine, placed in the mouth and chewed or liquefied and injected with a syringe.
Where can I find it?
Bath salts can be purchased in many states in tobacco shops, paraphernalia shops (Head Shops) and many gas stations in states that have not outlawed the substance. These drugs can also be easily purchased online where they do not follow state restrictions. Kansas HAS outlawed the substance and any and all analogues.
What are the dangers?
"Abusers of "bath salt" products have reported that they have experienced many adverse effects such as…"  chest pain, increased blood pressure, increased heart rate, agitation, panic attacks, hallucinations, extreme paranoia and delusions. Aside from the reported side effects are reports of suicidal ideations that have become increasingly common. A quick Google search of "Bath Salts Suicides" returned 506,000 results. Another danger to note is the lack of complete understanding of long term effects. These drugs are relatively new and created by street chemists, due to this fact it is difficult to know what the long term effects of the drug use will be.
