Heroin, also known as diacetylmorphine and diamorphine among other names, is a morphinan opioid substance synthesized from the dried latex of the opium poppy; it is mainly used as a recreational drug for its euphoric effects. Heroin is used medically in several countries to relieve pain, such as during childbirth or a heart attack. Medical-grade diamorphine is used as a pure hydrochloride salt. Various white and brown powders sold illegally around the world as heroin are routinely diluted with cutting agents. Black tar heroin is a variable admixture of morphine derivatives—predominantly 6-MAM (6-monoacetylmorphine), which is the result of crude acetylation during clandestine production of street heroin. Heroin is typically injected, usually into a vein, but it can also be snorted, smoked, or inhaled. In a clinical context, the route of administration is most commonly intravenous injection; it may also be given by intramuscular or subcutaneous injection, as well as orally in the form of tablets. The onset of effects is usually rapid and lasts for a few hours. Common side effects include respiratory depression (decreased breathing), dry mouth, drowsiness, impaired mental function, constipation, and addiction. Use by injection can also result in abscesses, infected heart valves, blood-borne infections, and pneumonia. After a history of long-term use, opioid withdrawal symptoms can begin within hours of the last use. When given by injection into a vein, heroin has two to three times the effect of a similar dose of morphine. It typically appears in the form of a white or brown powder. Treatment of heroin addiction often includes behavioral therapy and medications. Medications can include buprenorphine, methadone, or naltrexone. A heroin overdose may be treated with naloxone. As of 2015, an estimated 17 million people use opiates non-medically, of which heroin is the most common, and opioid use resulted in an estimated 109-129 thousand deaths in 2015; The total number of heroin users worldwide is believed to have increased in Africa, the Americas, and Asia between 2000 and 2015. In the United States, approximately 1.6 percent of people reported using heroin at some point in their lives and 0.4% of people aged 12 or older in 2021 reported using heroin in the past 12 months. When people die from overdosing on a drug, the drug is usually an opioid and often heroin. Heroin was first made by C. R. Alder Wright in 1874 from morphine, a natural product of the opium poppy. Internationally, heroin is controlled under Schedules I and IV of the Single Convention on Narcotic Drugs, and it is generally illegal to make, possess, or sell without a license. About 448 tons of heroin were made in 2016. In 2015, Afghanistan produced about 66% of the world's opium. Illegal heroin is often mixed with other substances such as sugar, starch, caffeine, quinine, or other opioids like fentanyl.
Uses
Recreational
Bayer's original trade name of heroin is typically used in non-medical settings. It is used as a recreational drug for the euphoria it induces. Anthropologist Michael Agar once described heroin as "the perfect whatever drug." Tolerance develops quickly, and increased doses are needed in order to achieve the same effects. Its popularity with recreational drug users, compared to morphine, reportedly stems from its perceived different effects. Short-term addiction studies by the same researchers demonstrated that tolerance to heroin and morphine developed at a similar rate. When compared to the opioids hydromorphone, fentanyl, oxycodone, and pethidine (meperidine), former addicts showed a strong preference for heroin and morphine, suggesting that heroin and morphine are particularly susceptible to misuse and causing dependence. Morphine and heroin were also much more likely to produce euphoria and other positive subjective effects when compared to these other opioids. Heroin came into widespread use in South Africa in 2009 but the epidemic of heroin addiction has escalated since 2013 as prices have fallen rapidly in recent years. Heroin is primarily used by unemployed young men. Heroin generates intense feelings of euphoria, deep contentment, and relaxation. It also reduces appetite. Effects may last two to four hours. The drug can be inhaled after being warmed in a glass pipe but can be also smoked with cannabis in the form of a joint,. It is primarily injected intravenously.
