I told myself I'd never smoke Salvia again. However, after experiencing what I thought was literally death.... it does interest me in retrospect. Most unique experience I ever had, left me kinda depressed/whacked out for days after though. My buddies handed me a pipe and I expected it was just Weed, and at the time I wasn't prepared for the trippy effects.
If I ever smoked it again, I'd try to plan it out, and do it like the Shamans do! In a dark place, lying down, with very calming music playing. And someone to watch me so I didn't hurt myself.
