Imagine the police bursting down your door with their drug dogs as you try and take a hot bath with your relaxing bath salts.
Maybe it’s not that dramatic--but bath salts are going on the chopping block in many states.
Of course, the state's solution is always to create new laws and make up more invented "crimes". If the state gives itself the "legal" right to use force against people who refuse to stop selling and using bath salts, I will also have the right to use force against people using and selling things I think are harmful. Oh, wait, no I won't (I was using Bret Alan's brain for a moment, sorry).
