Chasing the dragon

"Chasing the dragon" (traditional Chinese: 追龍; simplified Chinese: 追龙; pinyin: zhuī lóng; Jyutping: zeoi1 lung4) is a slang phrase of Cantonese origin from Hong Kong referring to inhaling the vapor from a heated solution of morphine, heroin, oxycodone, opium, or ya ba (a pill containing caffeine and methamphetamine). The "chasing" occurs as the user gingerly keeps the liquid moving in order to keep it from overheating and burning up too quickly, on a heat conducting material such as aluminium foil. The moving smoke is chased after with a tube through which the user inhales.[1] The process may be referred to as a "foily" in Australian English.[2]

Another use of the term "chasing the dragon" refers to the elusive pursuit of a high equal to the user’s first in the use of a drug, which after acclimation is no longer achievable.[3]

Advantages[]

This method of intake significantly decreases or eliminates certain risks of heroin use, such as the transmission of HIV, hepatitis, and other diseases through needle sharing, the introduction of skin bacteria to the bloodstream due to non-sterile injection, and the stress that injection puts on veins cannot occur.

Risks[]

It is always harmful to expose the lungs to any kind of smoke or heated vapor.[4]

Drug overdose[]

A drug overdose caused by chasing the dragon is hard to predict because this technique doesn't deliver a standardized dosage. It's virtually impossible even for skilled users to know how much of the substance that has been evaporated, burned, and inhaled. These combined factors may create a false sense of security when a given dose seem safe to repeat, but may cause an overdose when all the factors are randomly excluded.

Lung cancer from natural talc[]

Illicit drugs that occur as white powder in their pure form are often cut with cheap talc. Natural talc is cheap but contains asbestos while asbestos-free talc is more expensive. Inhaled talc that has asbestos is generally accepted as being able to cause lung cancer if it is inhaled. The evidence about asbestos-free talc is less clear, according to the American Cancer Society.[5]

Substance specific[]

Heroin[]

Inhaling heroin appears to rarely lead to toxic leukoencephalopathy.[6][7] There are also documented cases of both severe acute asthma and exacerbation of underlying asthma caused by heroin inhalation, potentially resulting in death.[8][9][10]
