hey, Im not old enough to buy from headshops, but I still do. It doesn't seem to really matter...they just say u need to be 18+ for legal reasons, but do not enforce it really. I know of a product called Total Impact and it contains salvia divinorum, wild dagga (mild marijuana alternative), and some other herbs to enhance the effects. I personally like it a lot when I mix another product called Aztec Gold liquid extract to it. It gets me feelin pretty outta it. If anyone's interested, goto http://www.blazeblock.com . Thats where I buy all my shit and they give me free samples in every order as well.
