chemicals commonly used to make bath salts: mephedrone, MDPV, and methylone. its basically synthetic crack and synthetic meth mixed together that can either be snorted or smoked. like any other drug of this sort there could be anything used to cut it even rat poison you never know. if you have ever tried salvia then you already know the effect of just one of the two chemicals of bath salts so imagine a longer effect of salvia but 10 times worse and you can understand why these people go completely nuts.
