What is Heroin?

Heroin is an illegal, highly addictive opioid 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 Colombia. Heroin can be a white or brown powder, or a black sticky substance known as black tar heroin. Other common names for heroin include big H, horse, hell dust, and smack.1

Know That Heroin Use is on the Rise

Heroin use has increased sharply across the United States among men and women, most age groups, and all income levels. Some of the greatest increases occurred in demographic groups with historically low rates of heroin use, including women, people who are privately insured, and people with higher incomes. Not only are people using heroin, they are also using multiple other substances, including cocaine and prescription opioids. Nearly all people who use heroin also use at least one other drug.2

Know About Heroin and Opioids

Prescription opioid pain medicines such as OxyContin® and Vicodin® have affects similar to heroin. Research suggests that misuse of these drugs may open the door to heroin use. Recent data also suggests that heroin is frequently the first opioid people use. In a study of those entering treatment for opioid use disorder, approximately one-third reported heroin as the first opioid they used regularly to get high.3 This suggests that prescription opioid misuse is just one factor leading to heroin use.

Know Other Potential Health Effects of Heroin Use

Heroin often contains additives, such as sugar, starch, or powdered milk that can clog blood vessels leading to the lungs, liver, kidneys, or brain, causing permanent damage.
