Opiates are often referred to as narcotics and have been used medically to relieve pain for centuries. In the early 19th century, pure morphine extract was suitable for solution, and with the advent of the hypodermic needle in the mid-19th century, injection of morphine became a common method of pain relief. In 1898, heroin was introduced into the medical community as a remedy for addiction to morphine. However, it was soon revealed that heroin was even more likely to produce addiction than morphine. While opiates began their start in the medical community, they have quickly become one of the most commonly abused drug groups. Today, only codeine and morphine are still used in the clinical setting for pain management. The opiates drug group includes opium, morphine, codeine and heroin, among other synthetic opiates such as Demerol.

Short-term and Long-term Effects of Opiates

In the United States, opiate addiction has increased dramatically over the last decade mainly due to the rising level of pain killer addiction. Many people are ignorant to the fact that these pain killers are just like heroin.
