Heroin, also known as diacetylmorphine and diamorphine among other names, is a morphinan opioid substance synthesized from the dried latex of the Papaver somniferum plant; it is mainly used as a recreational drug for its euphoric effects. 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 used medically in several countries to relieve pain, such as during childbirth or a heart attack, as well as in opioid replacement therapy.
Methadone, sold under the brand names Dolophine and Methadose among others, is a synthetic opioid agonist used for chronic pain and also for opioid use disorder. It is used to treat chronic pain, and it is also used to treat addiction to heroin or other opioids. Prescribed for daily use, the medicine relieves cravings and removes withdrawal symptoms. Withdrawal management using methadone can be accomplished in less than a month, or it may be done gradually over a longer period of time, or simply maintained for the rest of the patient's life. While a single dose has a rapid effect, maximum effect can take up to five days of use. After long-term use, in people with normal liver function, effects last 8 to 36 hours. Methadone is usually taken by mouth and rarely by injection into a muscle or vein.
Harm reduction, or harm minimization, refers to a range of intentional practices and public health policies designed to lessen the negative social and/or physical consequences associated with various human behaviors, both legal and illegal. Harm reduction is used to decrease negative consequences of recreational drug use and sexual activity without requiring abstinence, recognizing that those unable or unwilling to stop can still make positive change to protect themselves and others.
Hydromorphone, also known as dihydromorphinone, and sold under the brand name Dilaudid among others, is a morphinan opioid used to treat moderate to severe pain. Typically, long-term use is only recommended for pain due to cancer. It may be used by mouth or by injection into a vein, muscle, or under the skin. Effects generally begin within half an hour and last for up to five hours. A 2016 Cochrane review found little difference in benefit between hydromorphone and other opioids for cancer pain.
Opioid use disorder (OUD) is a substance use disorder characterized by cravings for opioids, continued use despite physical and/or psychological deterioration, increased tolerance with use, and withdrawal symptoms after discontinuing opioids. Opioid withdrawal symptoms include nausea, muscle aches, diarrhea, trouble sleeping, agitation, and a low mood. Addiction and dependence are important components of opioid use disorder.
Buprenorphine, sold under the brand name Subutex among others, is an opioid used to treat opioid use disorder, acute pain, and chronic pain. It can be used under the tongue (sublingual), in the cheek (buccal), by injection, as a skin patch (transdermal), or as an implant. For opioid use disorder, the patient must have moderate opioid withdrawal symptoms before buprenorphine can be administered under direct observation of a health-care provider.
A methadone clinic is a medical facility where medications for opioid use disorder (MOUD) are dispensed-—historically and most commonly methadone, although buprenorphine is also increasingly prescribed. Medically assisted drug therapy treatment is indicated in patients who are opioid-dependent or have a history of opioid dependence. Methadone is a schedule II (USA) opioid analgesic, that is also prescribed for pain management. It is a long-acting opioid that can delay the opioid withdrawal symptoms that patients experience from taking short-acting opioids, like heroin, and allow time for withdrawal management. In the United States, by law, patients must receive methadone under the supervision of a physician, and dispensed through the Opioid Treatment Program (OTP) certified by the Substance Abuse and Mental Health Services Administration and registered with the Drug Enforcement Administration.
Vincent Dole was an American doctor, who, along with his wife, Marie Nyswander, developed the use of methadone to treat heroin addiction. Dole and Nyswander, in establishing methadone maintenance treatment (MMT), improved treatment options in addiction medicine which for a century had been based on the conventional view that narcotic addiction was the result of an intractable moral defect. His work resulted in the partial re-legalization of opioid maintenance in the United States. For this contribution he was a recipient of the 1970 Canada Gairdner International Award, and the 1988 Albert Lasker Award for Clinical Medical Research.
Heroin-assisted treatment (HAT), or diamorphine-assisted treatment, refers to a type of Medication-Assisted Treatment (MAT) where semi-synthetic heroin is prescribed to opiate addicts who do not benefit from, or cannot tolerate, treatment with one of the established drugs used in opiate replacement therapy such as methadone or buprenorphine. For this group of patients, heroin-assisted treatment has proven superior in improving their social and health situation. Heroin-assisted treatment is fully a part of the national health system in Switzerland, Germany, the Netherlands, Canada, and Denmark. Additional trials are being carried out in the United Kingdom, Norway, and Belgium.
An opiate is an alkaloid substance derived from opium. It differs from the similar term opioid in that the latter is used to designate all substances, both natural and synthetic, that bind to opioid receptors in the brain. Opiates are alkaloid compounds naturally found in the opium poppy plant Papaver somniferum. The psychoactive compounds found in the opium plant include morphine, codeine, and thebaine. Opiates have long been used for a variety of medical conditions, with evidence of opiate trade and use for pain relief as early as the eighth century AD. Most opiates are considered drugs with moderate to high abuse potential and are listed on various "Substance-Control Schedules" under the Uniform Controlled Substances Act of the United States of America.
Marie Nyswander was an American psychiatrist and psychoanalyst known for developing and popularizing the use of methadone to treat heroin addiction.
Substance use disorder (SUD) is the persistent use of drugs despite the substantial harm and adverse consequences to one's own self and others, as a result of their use. In perspective, the effects of the wrong use of substances that are capable of causing harm to the user or others, have been extensively described in different studies using a variety of terms such as substance use problems, problematic drugs or alcohol use, and substance use disorder. The National Institute of Mental Health (NIMH) states that "Substance use disorder (SUD) is a treatable mental disorder that affects a person's brain and behavior, leading to their inability to control their use of substances like legal or illegal drugs, alcohol, or medications. Symptoms can be moderate to severe, with addiction being the most severe form of SUD". Substance use disorders (SUD) are considered to be a serious mental illness that fluctuates with the age that symptoms first start appearing in an individual, the time during which it exists and the type of substance that is used. It is not uncommon for those who have SUD to also have other mental health disorders. Substance use disorders are characterized by an array of mental/emotional, physical, and behavioral problems such as chronic guilt; an inability to reduce or stop consuming the substance(s) despite repeated attempts; operating vehicles while intoxicated; and physiological withdrawal symptoms. Drug classes that are commonly involved in SUD include: alcohol (alcoholism); cannabis; opioids; stimulants such as nicotine, cocaine and amphetamines; benzodiazepines; barbiturates; and other substances.
