Yes and it is more dangerous now because they have to work around the bans have a chem called AM2201 in all the incense now.....believe me this one is going to make people very sick......and the withdrawl from it is hell on earth.

anecdotal reports of individuals experiencing panic attacks and vomiting, at doses as small as 2 milligrams. As the dosage is much smaller than most other synthetic cannabinoids, users may accidentally dose too much. Convulsions have been reported at doses exceeding 10 milligrams.[2] Caution should be taken if using this substance as it is active at doses as small as 500 µg (micrograms), has a very steep dose-response curve, and tolerance builds up very quickly to the effects. As of November 2011, there have been no reports of death associated with the drug. The toxicity of AM-2201 is still a matter of debate and there may be long term side effects.
