Salvia divinorum is completely legal. Don't ask me how or why it's legal, just know that it is, in fact, LEGAL. Salvia is a powerful psychoactive plant, a member of the sage genus and the mint family. It pretty much makes you trip like you're on mushrooms, but the trip hits you instantly upon exhaling, and only lasts a few minutes. Salvia is most effective if you smoke it out of a bong. From experience I do not recommend the purchase or use of salvia. It's a waste of money, if you really want to do drugs, then do illegal drugs! If you're still thinking about trying it... Here's a few videos of some idiots tripping on salvia. Maybe they'll make you change your mind.
