Heroin is a highly addictive narcotic. It is available in a tarlike substance or dark brown powder, and is typically injected, snorted, or smoked. Heroin is an opiate that comes from morphine, and is classified by the DEA as a Schedule I controlled substance.[1]

Heroin is a "downer" that disrupts the brain's ability to perceive pain, and affects the brain's pleasure systems.[1] Morphine, from which the drug heroin is processed, is most commonly found in poppy plants that are grown in Southwest and Southeast Asia, Colombia, and Mexico.[2]

Physiologic Effects of Heroin

Heroin is converted to Morphine once it enters a person's brain, where it binds itself to opiod receptors. Located in various parts of the brain, these receptors are responsible for an individual's perception of reward and pain. Those who administer heroin to themselves intravenously reportedly feel an immediate euphoria. This is followed by a warm feeling in the skin, dry mouth, heavy muscles, and a foggy mental state.[3]

There are numerous side effects associated with heroin use, most notably its tendency to create physical dependence. Long-term heroin users, especially those who inject the drug, may develop liver or kidney disease, collapsed veins or abscesses. These individuals may also contract infectious diseases as a result of sharing heroin needles with other users. Additionally, long-term users may experience withdrawal symptoms that include muscle pain, insomnia, vomiting, diarrhea, restlessness, and cold flashes. These users may need help to get off the drug. Drugs that help individuals to detox from heroin include Methadone, Naltrexone, Naloxone, and Buprenorphone.[3]

Heroin Legal Status

Heroin is a Schedule I controlled substance due to its abusive nature. There are no medical uses for the drug that are currently accepted and there are no safety procedures for the drug to be administered under medical supervision. Heroin is considered to be highly addictive and the most rapidly active drug in the opiate family.[2] Prior to becoming illegal, heroin was once considered a "cure-all", a non-addictive alternative to Morphine and Codeine.
