when i smoked it i used about 1/2 gram, or 1/2 of the tube it is in. I didn't like salvia at all it made me nuts and insane, it wasn't a nice feeling it felt like my body was being ripped apart and i couldn't stop talking to try to describe it. I got lost in a world but not hallucinating i would believe things like people were against me or i had a missions to fulfill. Smoke it with weed cuz the salvia high is only like 5-20 minutes. You probably wont like it but its good to try it and know. Good luck anyhow.
