CA has banned the sale of Salvia divinorum to minors. Several states have banned the plant outright. I wouldn't be surprized if the DEA steps in sometime soon and use its emergency powers to place the drug on Schedule I, just as it did with Ecstasy. That would be a shame because the drug is quite interesting from a pharmacological standpoint (I think it's the most potent natural psychoactive compound known, and a previously unknown class of drugs), and rapid progress is being made in studying its activity. A DEA ban would place a burden on researchers, and probably inhibit research progress.

BTW, CA is the home of the Salvia divinorum Research and Information Center.
