This method can also be used to freebase cocaine or meth, or to smoke opium or hash. Basically any drug that can be imbibed through inhalation can be placed on a non-flammable substance such as a thin piece of glass or aluminum foil as described by dead, lit from underneath and chased in this way. I have heard stories of crackheads clumsily chasing the dragon off aluminum foil when they don't have access to the typical glass pipe.

I had been told that chasing the dragon had originated in Hong Kong for use with opium.
