Have we seen such activity when ephedra and kava kava, or any other herbal drugs were banned, for instance?
ephedra hasn't been banned as far as i know in general, just in diet supplements. i bought some from drugstore.com last year. it's an otc asthma drug, i think.
that may more be a function of having a large indigenous population, than libertarianism, i think. i'd have to look into similar laws in the other southwest and northcentral states. and i'm way too lazy to do that. but it's something to consider.
