They are absolutely full of it. They were banning K2 and the like before they actually started research on any possible side effects. Don't be foolish. They don't care about the well-being of Americans, otherwise the FDA and Big Pharma wouldn't be getting away with all the toxins they push on us! Provided there are age restrictions, If someone wants some k2 herb, who are you to tell them that they can't have it? If someone wants to, they will buy k2 smoke whether it's legal or not as that is what happens with anything else that is unjustly and ridiculously prohibited. K2 incense will be no different. Plus, the formulas are constantly changing. http://www.k2incense.org Offers several products that are legal all over the world.
Bwah ha ha - but now I will make synthetic synthetic marijuana!
