File:Salvinorin Spot.jpg

Summary
This is a spot of Salvinorin, the active principal of Salvia divinorum on a sheet of aluminum foil. It contains a trace amount of waxy lipids from the plant, hence the greenish tint and border. The spot is estimated to contain 0.75mg of Salvinorin, which is enough to cause significant psychoactive effects when vaporized and inhaled. It was placed there by dripping one drop of Salvinorin-saturated acetone onto the foil from a dropper, and then allowing the acetone to evaporate. I created the spot and took the picture myself.
