abstract:"Chasing the dragon" (a slang phrase of Cantonese origin from Hong Kong, Traditional Chinese: 追龍, Simplified Chinese: 追龙, Cantonese Jyutping: zeoi1 lung4, pinyin: zhuī lóng) refers to inhaling the vapor from heated morphine, heroin, oxycodone or opium that has been placed on a piece of foil. The 'chasing' occurs as the user gingerly keeps the liquid moving in order to keep it from coalescing into a single, unmanageable mass.
So, he's gone from the streets to the forest and he's recorded his adventures in several books: Jaguar, Chasingthe Dragon's Tail, and more recently, Beyond the Last Village.
