The Controlled Substances Act (CSA) is the statute establishing federal U.S. drug policy under which the manufacture, importation, possession, use, and distribution of certain substances is regulated. It was passed by the 91st United States Congress as Title II of the Comprehensive Drug Abuse Prevention and Control Act of 1970 and signed into law by President Richard Nixon. The Act also served as the national implementing legislation for the Single Convention on Narcotic Drugs.
Oxycodone, sold under various brand names such as Roxicodone and OxyContin, is a semi-synthetic opioid used medically for treatment of moderate to severe pain. It is highly addictive and is a commonly abused drug. It is usually taken by mouth, and is available in immediate-release and controlled-release formulations. Onset of pain relief typically begins within fifteen minutes and lasts for up to six hours with the immediate-release formulation. In the United Kingdom, it is available by injection. Combination products are also available with paracetamol (acetaminophen), ibuprofen, naloxone, naltrexone, and aspirin.
Thebaine (paramorphine), also known as codeine methyl enol ether, is an opiate alkaloid, its name coming from the Greek Θῆβαι, Thēbai (Thebes), an ancient city in Upper Egypt. A minor constituent of opium, thebaine is chemically similar to both morphine and codeine, but has stimulatory rather than depressant effects. At high doses, it causes convulsions similar to strychnine poisoning. The synthetic enantiomer (+)-thebaine does show analgesic effects apparently mediated through opioid receptors, unlike the inactive natural enantiomer (−)-thebaine. While thebaine is not used therapeutically, it is the main alkaloid extracted from Papaver bracteatum and can be converted industrially into a variety of compounds, including hydrocodone, hydromorphone, oxycodone, oxymorphone, nalbuphine, naloxone, naltrexone, buprenorphine, butorphanol and etorphine.
The term narcotic originally referred medically to any psychoactive compound with numbing or paralyzing properties. In the United States, it has since become associated with opiates and opioids, commonly morphine and heroin, as well as derivatives of many of the compounds found within raw opium latex. The primary three are morphine, codeine, and thebaine.
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.
Mitragyna speciosa is a tropical evergreen tree in the coffee family native to Southeast Asia. It is indigenous to Cambodia, Thailand, Indonesia, Malaysia, Myanmar, and Papua New Guinea, where it has been used in herbal medicine since at least the 19th century. It has also historically been used for chewing, smoking, and tea. Kratom has opiate properties and some stimulant-like effects.
Oxymorphone is a highly potent opioid analgesic indicated for treatment of severe pain. Pain relief after injection begins after about 5–10 minutes, after oral administration it begins after about 30 minutes, and lasts about 3–4 hours for immediate-release tablets and 12 hours for extended-release tablets. The elimination half-life of oxymorphone is much faster intravenously, and as such, the drug is most commonly used orally. Like oxycodone, which metabolizes to oxymorphone, oxymorphone has a high potential to be abused.
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.
Nalbuphine, sold under the brand names Nubain among others, is an opioid analgesic which is used in the treatment of pain. It is given by injection into a vein, muscle, or fat.
Dihydromorphine is a semi-synthetic opioid structurally related to and derived from morphine. The 7,8-double bond in morphine is reduced to a single bond to get dihydromorphine. Dihydromorphine is a moderately strong analgesic and is used clinically in the treatment of pain and also is an active metabolite of the analgesic opioid drug dihydrocodeine. Dihydromorphine occurs in trace quantities in assays of opium on occasion, as does dihydrocodeine, dihydrothebaine, tetrahydrothebaine, etc. The process for manufacturing dihydromorphine from morphine for pharmaceutical use was developed in Germany in the late 19th century, with the synthesis being published in 1900 and the drug introduced clinically as Paramorfan shortly thereafter. A high-yield synthesis from tetrahydrothebaine was later developed.
Thebacon, or dihydrocodeinone enol acetate, is a semisynthetic opioid that is similar to hydrocodone and is most commonly synthesised from thebaine. Thebacon was invented in Germany in 1924, four years after the first synthesis of hydrocodone. Thebacon is a derivative of acetyldihydrocodeine, where only the 6–7 double bond is saturated. Thebacon is marketed as its hydrochloride salt under the trade name Acedicon, and as its bitartrate under Diacodin and other trade names. The hydrochloride salt has a free base conversion ratio of 0.846. Other salts used in research and other settings include thebacon's phosphate, hydrobromide, citrate, hydroiodide, and sulfate.
Hydrocodone/paracetamol is the combination of the pain medications hydrocodone and paracetamol (acetaminophen). It is used to treat moderate to severe pain. It is taken by mouth. Recreational use is common in the United States.
Codeine is an opiate and prodrug of morphine mainly used to treat pain, coughing, and diarrhea. It is also commonly used as a recreational drug. It is found naturally in the sap of the opium poppy, Papaver somniferum. It is typically used to treat mild to moderate degrees of pain. Greater benefit may occur when combined with paracetamol (acetaminophen) or a nonsteroidal anti-inflammatory drug (NSAID) such as aspirin or ibuprofen. Evidence does not support its use for acute cough suppression in children or adults. In Europe, it is not recommended as a cough medicine in those under 12 years of age. It is generally taken by mouth. It typically starts working after half an hour, with maximum effect at two hours. Its effects last for about four to six hours. Codeine exhibits abuse potential similar to other opioid medications, including a risk of habituation and overdose.
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.
Ethoheptazine is an opioid analgesic from the phenazepane family. It was invented in the 1950s and is a ring expanded analogue of pethidine.
Metethoheptazine (WY-535) is an opioid analgesic from the phenazepine family. It was invented in the 1960s.
AH-7921 is an opioid analgesic drug selective for the μ-opioid receptor, having around 90% the potency of morphine when administered orally. It was discovered in the 1970s by a team at Allen and Hanburys located in the United Kingdom. The drug is considered a new psychoactive substance (NPS) in which it is synthetically created in laboratories to mimic that of controlled substances. The substance has also been sold on the internet since 2012 as a "research chemical". When sold online it may be called the alternative name doxylam, not to be confused with doxylamine. AH-7921 has never progressed to clinical trials. The DEA is not aware of any medical usage in the United States, and has not insisted the Health and Human Services department (HHS) to conduct any medical research of the substance's uses.
Naldemedine is a medication that is used for the treatment of opioid-induced constipation in adults with chronic non-cancer pain. It is a peripherally acting μ-opioid receptor antagonist and was developed by Shionogi. Clinical studies have found it to possess statistically significant effectiveness for these indications and to be generally well tolerated, with predominantly mild to moderate gastrointestinal side effects. Effects indicative of central opioid withdrawal or impact on the analgesic or miotic effects of co-administered opioids have only been observed in a small number of patients.
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.
