My first time trying Salvia, I tried 5x after a nice high off of JuicyFruit was going smooth, and the first hit I took, I LAUGHED like there was no end. I was a lot more relaxed, no CEV or anything like that, but I'm going to try it on its own pretty soon. I only feel comfortable in my friend's apartment; he's rather experienced and is the type of person who can definately improve the high just by sitting there.
