Out of all the acid, shrooms and various ritualisitic drugs I've tried, salvia divinorum is one of the strangest and enlightening experiences. With extracts salvia can be very powerful; smoking 1 hit of 40X extract is like taking 40 hits of plain leaf salvia at once.

Salvia can be scary, funny, relaxing or just plain unsettling, but just remember that you're gonna be feeling mighty weird. After all you just took the universe, loaded it into a cannon and fired it directly at your brain.
Haha, Zenf!
