What is Heroin?

Heroin is an opiate drug that is synthesized from morphine, a substance extracted from the seed pod of the opium poppy plant. Typically found as a white or brown powder or a black sticky substance known as “black tar heroin,” it is commonly injected, snorted, or smoked. Once inside the body, heroin rapidly converts to morphine and binds to opioid receptors in the brain and body, especially those involved in pain perception and pleasure, as well as vital functions like breathing and heart rate.

The drug’s euphoric effects, along with its ability to relieve pain, contribute to its high potential for addiction. Repeated use leads to tolerance, dependence, and a compulsion to continue using despite harmful consequences—a hallmark of addiction. Because heroin suppresses the respiratory system, overdose can result in slowed or stopped breathing, leading to coma or death.

Heroin addiction is considered a serious public health issue due to its links to increased rates of infectious diseases (from needle sharing), fatal overdoses, and social consequences such as criminal activity. Treatment often involves medication-assisted therapy (MAT) with drugs like methadone, buprenorphine, or naltrexone, alongside counseling and behavioral therapies.

As a Schedule I controlled substance in the United States, heroin has no accepted medical use and a high potential for abuse. Recovery from heroin addiction is possible with appropriate intervention, support, and long-term treatment strategies.
