What Is Heroin Addiction?
Heroin is one of the most addictive substances in existence. It is a potent opiate drug made from morphine, a natural substance taken from the seed pod of the various opium poppy plants grown in Southeast and Southwest Asia, Mexico, and South America. It comes in a white or brown powder, or a black sticky substance known as black tar heroin. Users inject, sniff, snort or smoke heroin.
