Nothing stays the same.
Have you heard of K2? It's the stuff that is sold in "head shops" and quickie marts as "incense". Many states are in the process of of banning this substance, Kansas has already banned it. But already there is a new version out called K3. Methodology of the product is it is actually being smoked like weed although the packaging does explicitly caution against using the product in this way.
The new one that is hitting the scene is "Bath Salts" . A common brand name is Ivory Wave. The active ingredient is MDPV and it provides a high similar to Ecstasy. This can be snorted and some even just use it as a bath salt and experience a high. Unfortunately people are dying using this "legal" product in the way it is not intended on the package. The UK has already banned this substance.
It amazes me how the people who manufacture and sell these types of materials always seem to take the high road by prominently posting on the package to use this material only in the way prescribed.
It is sad there is a few people with such a lack of humanity that they would profit on destroying humanity.
