If I smoke just a tiny bit of weed (1 or 2 hits) and then smoke a bowl of salvia (just plain leaves) it makes me feel like I'm floating and like my body is pulling away from itself. It's relly trippy. You should also try smoking salvia after taking about 5 shots of your favorite drink and then smoke salvia. Wait until you feel a "buzz" from the alcohol before you smoke. When I did that I got an uncontrolable laughter for like 10-15 minutes and got an amazing body buzz.

Another thing to remember is that salvia has little or no effect on a small amount of people .
