There are many chemicals in synthetic marijuana, many that are still unknown to scientist and researchers of the incense. It is thought to be produced somewhere in china and distributes from there. k2, spice, Colorado chronic, is actually not suppose to be smoked, but because it mimics THC it has become more and more popular. The FDA or the DEA has not evaluated this substance so it is unknown what exactly is in synthetic weed.
