Canned air was barely enjoyable for me, but I did it a lot for a short while. I ended up doing too much once, getting sea sick because the room was spinning so bad, and puking. Since then, even the smell of canned air makes me feel sick. I'd never be able to do it again.

Salvia also tastes like shit to me. It has a really gross smell/taste, at least the stuff I did. I didn't have a bad experience from it or anything, I just didn't like it. I didn't feel anything and it smelled/tasted like shit. Why not just smoke a bowl of the good stuff instead.
