From what I can understand "Bath Salts" are basically meth. What the companies do is change the chemical formula slightly so it can't be classified as meth but it actually is with just a minor molecule tweak. This stuff is nothing like LSD, people saying it is is giving LSD a really bad rep. The stuff you might be thinking of is Salvia. Salvia is like LSD but only last a couple of minutes and in most cases is safe to take as long as you have someone watching you.
I totally agree that these "Bath Salts" need to be illegal and they need to make a law saying the taking a drug like meth and changing it slightly so it gives the same affect can't be legally sold. The thing that pisses me off is we spend billions of dollars trying to stop weed, which has benefits, but allow crap like this to be sold in stores right down the road. Good job government, good job.
