This is the most Thorough article I've found on Salvia yet
http://www.maps.org/media/abcsalvia.html
I read through this whole thing, which I came upon through google, and I thought I'd share it with everybody here since there's so many questions about it. I've explored the web and read many articles on salvia, but I'd definately say this one contains the most information about legal status, public opinion, effects, health concerns, research, and historical spiritual use. enjoy :)
