Heroin is an opiate, in a class of narcotics, powerful pain relieving drugs such as morphine. Opiates are used in medicine to treat pain associated with surgeries and illnesses. Heroin is produced from an annual herb native to Southeastern Europe, Western Asia and grown in Mexico, Guatemala, and Columbia called the Opium Poppy.
