History/Background of Heroin

Heroin comes from the Opium poppy, a plant that's found in the Middle East, South Asia and Central South America. The main ingredient of raw opium is morphine and they chemically transform it into heroin. The first production of heroin was in 1874. Fifty years later the heroin act made it illegal in the United States and around the same time made it illegal in several other countries.

How it is used

Heroin can be smoked, snorted, or injected through a person's veins. This is the method must users use and is also the most dangerous due to dirty needles and it is the easiest to over dose on.
