text: Sublingual absorbtion:  the absorbtion of a substance through a mucous membrane...\n\nIs not faster than smoking, but significantly faster than oral consumption... reason being that oral consumption requires the substance to pass through the gastro intestinal system first (you have to digest it) whereas sublingual absorbtion goes directly to the bloodstream...  sublingual absorbtion can also be expodited (speed up) by introducing food grade ethanol (alcohol), however, mixing drugs is a foolish and potentialy dagerous endeavor...  Please use caution.
