Salvia is a very interesting and manageable short trip. As long as you're relaxed while you're tripping, you'll be good. I bought some 40x a while back and took several tokes and ended up with a very very interesting experience As for legal buds, it isn't a psychoactive high, so it's not going to be all that close to a high from pot, but I'm thinking of buying some sometime just to check it out. It's relatively cheap, so I'd give it a go.
