salvia is available in most head shops and is still pretty much legal everywhere. best smoked from either a pipe or a bong using a butane lighter to torch the salvia to a higher temp. You might want to start on the 10x salvia to get used to it as its a pretty strong exp.

is a very good site with a lot of info on how to use salvia divinorum. Recommend it highly. Dunno bout buying from it but from what i remember its supposed to be pretty good.
