Heroin also known diamorphine, is an opioid used as a recreational drug for its euphoric effects. Medical grade diamorphine is used as a pure hydrochloride salt which is distinguished from black tar heroin, a variable admixture of morphine derivatives—predominantly 6-MAM (6-monoacetylmorphine), which is the result of crude acetylation during clandestine production of street heroin.
Diamorphine is used medically in several countries to relieve pain, such as during childbirth or a heart attack, as well as in opioid replacement therapy. It is typically injected, usually into a vein, but it can also be smoked, snorted, 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.
Uses of Heroin
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 effect.
In the United States, heroin is not accepted as medically useful.
Under the generic name diamorphine, heroin is prescribed as a strong pain medication in the United Kingdom, where it is administered via oral, subcutaneous, intramuscular, intrathecal, intranasal or intravenous routes. It may be prescribed for the treatment of acute pain, such as in severe physical trauma, myocardial infarction, post-surgical pain and chronic pain, including end-stage terminal illnesses.
Dosage and Administration
Use of heroin by mouth is less common than other methods of administration, mainly because there is little to no “rush”, and the effects are less potent. Heroin is entirely converted to morphine by means of first-pass metabolism, resulting in deacetylation when ingested. Heroin’s oral bioavailability is both dose-dependent (as is morphine’s) and significantly higher than oral use of morphine itself, reaching up to 64.2% for high doses and 45.6% for low doses; opiate-naive users showed far less absorption of the drug at low doses, having bioavailability’s of only up to 22.9%. The maximum plasma concentration of morphine following oral administration of heroin was around twice as much as that of oral morphine.
Injection , is a popular method which carries relatively greater risks than other methods of administration. The dose of heroin used for recreational purposes is dependent on the frequency and level of use: thus a first-time user may use between 5 and 20 mg, while an established addict may require several hundred mg per day. As with the injection of any drug, if a group of users share a common needle without sterilization procedures, blood-borne diseases, such as HIV/AIDS or hepatitis, can be transmitted. The use of a common dispenser for water for the use in the preparation of the injection, as well as the sharing of spoons and filters can also cause the spread of blood-borne diseases.
Smoking heroin refers to vaporizing it to inhale the resulting fumes, rather than burning and inhaling the smoke. It is commonly smoked in glass pipes. Heroin may be smoked from aluminum foil, which is heated by an underneath flame, with the resulting smoke inhaled through a tube of rolled up foil.
Another popular route to intake heroin is insufflation (snorting), where a user crushes the heroin into a fine powder and then gently inhales it into the nose, where heroin is absorbed through the soft tissue in the mucous membrane of the sinus cavity and straight into the bloodstream. This method of administration redirects first-pass metabolism, with a quicker onset and higher bioavailability than oral administration, though the duration of action is shortened. This method is sometimes preferred by users who do not want to prepare and administer heroin for injection or smoking but still experience a fast onset. Snorting heroin becomes an often unwanted route, once a user begins to inject the drug. The user may still get high on the drug from snorting, and experience a nod, but will not get a rush. A “rush” is caused by a large amount of heroin entering the body at once. When the drug is taken in through the nose, the user does not get the rush because the drug is absorbed slowly rather than instantly.
Effects of Use
Common side effects include respiratory depression (decreased breathing), dry mouth, drowsiness, impaired mental function, constipation, and addiction. Side effects of use by injection can include 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. It typically comes as a white or brown powder.
