When taken properly they are used to treat many different types of pain including pain in teeth, skeletal system, skin, internal organs of the body. When used in high doses opiates can also relieve pain cause with certain types of cancer. The most commonly abused opiates are Hydrocodone, Oxycotin, Fentanyl, and Morphine. These substances are taken snorted, smoked and sometimes even injected to give a high close to heroine. Heroine is made from the opiate plant so these pain killers are basically synthetic heroine.

In 1914 when the Harrison Narcotic Act was passed the average opiate addict was a middle age, southern, white woman who functioned well and was adjusted to her role as a wife and a mother.
