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.
Recreational drug use is the use of one or more psychoactive drugs to induce an altered state of consciousness, either for pleasure or for some other casual purpose or pastime. When a psychoactive drug enters the user's body, it induces an intoxicating effect. Recreational drugs are commonly divided into three categories: depressants, stimulants, and hallucinogens.
Fentanyl is a potent synthetic piperidine opioid primarily used as an analgesic. It is 50 times more potent than heroin and 100 times more potent than morphine; its primary clinical utility is in pain management for cancer patients and those recovering from painful surgeries. Fentanyl is also used as a sedative. Depending on the method of delivery, fentanyl can be very fast acting and ingesting a relatively small quantity can cause overdose. Fentanyl works by activating μ-opioid receptors. Fentanyl is sold under the brand names Actiq, Duragesic and Sublimaze, among others.
Club drugs, also called rave drugs or party drugs, are a loosely defined category of recreational drugs which are associated with discothèques in the 1970s and nightclubs, dance clubs, electronic dance music (EDM) parties, and raves in the 1980s to today. Unlike many other categories, such as opiates and benzodiazepines, which are established according to pharmaceutical or chemical properties, club drugs are a "category of convenience", in which drugs are included due to the locations they are consumed and/or where the user goes while under the influence of the drugs. Club drugs are generally used by adolescents and young adults.
A drug overdose is the ingestion or application of a drug or other substance in quantities much greater than are recommended. Typically it is used for cases when a risk to health will potentially result. An overdose may result in a toxic state or death.
Colloquially known as "downers", depressants or central depressants are drugs that lower neurotransmission levels, or depress or reduce arousal or stimulation in various areas of the brain. Depressants do not change the mood or mental state of others. Stimulants, or "uppers", increase mental or physical function, hence the opposite drug class from depressants are stimulants, not antidepressants.
Hypoventilation occurs when ventilation is inadequate to perform needed respiratory gas exchange. By definition it causes an increased concentration of carbon dioxide (hypercapnia) and respiratory acidosis. Hypoventilation is not synonymous with respiratory arrest, in which breathing ceases entirely and death occurs within minutes due to hypoxia and leads rapidly into complete anoxia, although both are medical emergencies. Hypoventilation can be considered a precursor to hypoxia and its lethality is attributed to hypoxia with carbon dioxide toxicity.
Opioids are a class of drugs that derive from, or mimic, natural substances found in the opium poppy plant. Opioids work in the brain to produce a variety of effects, including pain relief. As a class of substances, they act on opioid receptors to produce morphine-like effects.
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.
Carfentanil or carfentanyl, sold under the brand name Wildnil, is an extremely potent opioid analgesic used in veterinary medicine to anesthetize large animals such as elephants and rhinoceroses. It is typically administered in this context by tranquilizer dart. Carfentanil has also been used in humans to image opioid receptors. It has additionally been used as a recreational drug, typically by injection, insufflation, or inhalation. Deaths have been reported in association with carfentanil.
Gray death is a slang term which refers to a potent mixture of synthetic opioids, for example benzimidazole opioids or fentanyl analogues, often sold on the street misleadingly as "heroin". However, other substances such as cocaine have also been laced with opioids that resulted in illness and death.
Xylazine is a structural analog of clonidine and an alpha-2 adrenergic receptor agonist, sold under many trade names worldwide, most notably the Bayer brand name Rompun, as well as Anased, Sedazine and Chanazine.
Brompton cocktail, sometimes called Brompton mixture or Brompton's cocktail, was an elixir meant for use as a pain suppressant dosed for prophylaxis. Made from morphine or diacetylmorphine (heroin), cocaine, highly-pure ethyl alcohol, and sometimes with chlorpromazine (Thorazine) to counteract nausea, it was given to terminally-ill individuals to relieve pain and promote sociability near death. A common formulation included "a variable amount of morphine, 10 mg of cocaine, 2.5 mL of 98% ethyl alcohol, 5 mL of syrup BP and a variable amount of chloroform water." Brompton's cocktail was given most in the mid twentieth century. It is now considered obsolete.
Lacing or cutting, in drug culture, refer to the act of using a substance to adulterate substances independent of the reason. The resulting substance is laced or cut.
Diacetyldihydromorphine is a potent opiate derivative developed in Germany in 1928 which is rarely used in some countries for the treatment of severe pain such as that caused by terminal cancer, as another form of diacetylmorphine. Diacetyldihydromorphine is fast-acting and longer-lasting than diamorphine, with a duration of action of around 4–7 hours.
The drug policy in the United States is the activity of the federal government relating to the regulation of drugs. Starting in the early 1900s, the United States government began enforcing drug policies. These policies criminalized drugs such as opium, morphine, heroin, and cocaine outside of medical use. The drug policies put into place are enforced by the Food and Drug Administration and the Drug Enforcement Administration. Classification of Drugs are defined and enforced using the Controlled Substance Act, which lists different drugs into their respective substances based on its potential of abuse and potential for medical use. Four different categories of drugs are Alcohol, Cannabis, Opioids, and Stimulants.
An opioid overdose is toxicity due to excessive consumption of opioids, such as morphine, codeine, heroin, fentanyl, tramadol, and methadone. This preventable pathology can be fatal if it leads to respiratory depression, a lethal condition that can cause hypoxia from slow and shallow breathing. Other symptoms include small pupils, and unconsciousness; however, its onset can depend on the method of ingestion, the dosage and individual risk factors. Although there were over 110,000 deaths in 2017 due to opioids, individuals who survived also faced adverse complications, including permanent brain damage.
Acetylfentanyl is an opioid analgesic drug that is an analog of fentanyl. Studies have estimated acetylfentanyl to be 15 times more potent than morphine, which would mean that despite being somewhat weaker than fentanyl, it is nevertheless still several times stronger than pure heroin. It has never been licensed for medical use and instead has only been sold on the illicit drug market. Acetylfentanyl was discovered at the same time as fentanyl itself and had only rarely been encountered on the illicit market in the late 1980s. However, in 2013, Canadian police seized 3 kilograms of acetylfentanyl. As a μ-opioid receptor agonist, acetylfentanyl may serve as a direct substitute for oxycodone, heroin or other opioids. Common side effects of fentanyl analogs are similar to those of fentanyl itself, which include itching, nausea and potentially fatal respiratory depression. Fentanyl analogs have killed hundreds of people throughout Europe and the former Soviet republics since the most recent resurgence in use began in Estonia in the early 2000s, and novel derivatives continue to appear.
There is an ongoing opioid epidemic in the United States, originating out of both medical prescriptions and illegal sources. The epidemic began in the United States in the late 1990s, according to the Centers for Disease Control and Prevention (CDC), when opioids were increasingly prescribed for pain management, resulting in a rise in overall opioid use throughout subsequent years.
The opioid epidemic, also referred to as the opioid crisis, is the rapid increase in the overuse, misuse/abuse, and overdose deaths attributed either in part or in whole to the class of drugs called opiates/opioids since the 1990s. It includes the significant medical, social, psychological, demographic and economic consequences of the medical, non-medical, and recreational abuse of these medications.
