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.
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.
Drug rehabilitation is the process of medical or psychotherapeutic treatment for dependency on psychoactive substances such as alcohol, prescription drugs, and street drugs such as cannabis, cocaine, heroin or amphetamines. The general intent is to enable the patient to confront substance dependence, if present, and stop substance misuse to avoid the psychological, legal, financial, social, and physical consequences that can be caused.
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, it is typically started when withdrawal symptoms have begun and for the first two days of treatment under direct observation of a health-care provider.
Naltrexone, sold under the brand names Revia and Vivitrol among others, is a medication primarily used to manage alcohol use or opioid use disorder by reducing cravings and feelings of euphoria associated with substance use disorder. It has also been found effective in the treatment of other addictions and may be used for them off-label. An opioid-dependent person should not receive naltrexone before detoxification. It is taken by mouth or by injection into a muscle. Effects begin within 30 minutes, though a decreased desire for opioids may take a few weeks to occur. Side effects may include trouble sleeping, anxiety, nausea, and headaches. In those still on opioids, opioid withdrawal may occur. Use is not recommended in people with liver failure. It is unclear if use is safe during pregnancy. Naltrexone is an opioid antagonist and works by blocking the effects of opioids, including both opioid drugs as well as opioids naturally produced in the brain.
Substance dependence, also known as drug dependence, is a biopsychological situation whereby an individual's functionality is dependent on the necessitated re-consumption of a psychoactive substance because of an adaptive state that has developed within the individual from psychoactive substance consumption that results in the experience of withdrawal and that necessitates the re-consumption of the drug. A drug addiction, a distinct concept from substance dependence, is defined as compulsive, out-of-control drug use, despite negative consequences. An addictive drug is a drug which is both rewarding and reinforcing. ΔFosB, a gene transcription factor, is now known to be a critical component and common factor in the development of virtually all forms of behavioral and drug addictions, but not dependence.
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 an Opioid Treatment Program (OTP) certified by the Substance Abuse and Mental Health Services Administration and registered with the Drug Enforcement Administration.
Treatment Improvement Protocols (TIPs) are a series of best-practice manuals for the treatment of substance use and other related disorders. The TIP series is published by the Substance Abuse and Mental Health Services Administration (SAMHSA), an operational division of the U.S. Department of Health and Human Services.
Drug detoxification is variously construed or interpreted as a type of “medical” intervention or technique in regards to a physical dependence mediated by a drug; as well as the process and experience of a withdrawal syndrome or any of the treatments for acute drug overdose (toxidrome). The first definition however, in relation to substance dependence and its treatment is arguably a misnomer and even directly contradictory since withdrawal is neither contingent upon nor alleviated through biological excretion or clearance of the drug. In fact, excretion of a given drug from the body is one of the very processes that leads to withdrawal since the syndrome arises largely due to the cessation itself and the drug being absent from the body; especially the blood plasma, not from ‘leftover toxins’ or traces of the drug still being in the system.
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.
Methadone maintenance treatment (MMT) utilizes methadone to treat dependence on heroin or other opioids, and is administered on an ongoing basis. Methadone is an opioid agonist that binds to the same receptors in the brain as heroin and other opioids. MMT is administered with the objective of relieving withdrawal symptoms. Higher doses of methadone may cause respiratory depression and/or euphoria in some patients. Methadone maintenance reduces the cravings for other opioids, and reduces the risk of fatal overdose from street drugs since the purity and strength of methadone is known, whereas substances obtained from the street vary significantly in strength and purity. Methadone maintenance has been termed "a first step toward social rehabilitation" because it increases the retention of patients in treatment, relieves them from the need to find, buy, and use multiple daily doses of street opioids, and offers a legal medical alternative.
Buprenorphine/naloxone, sold under the brand name Suboxone among others, is a fixed-dose combination medication that includes buprenorphine and naloxone. It is used to treat opioid use disorder, and reduces the mortality of opioid use disorder by 50%. It relieves cravings to use and withdrawal symptoms. Buprenorphine/naloxone is available for use in two different forms, under the tongue or in the cheek.
In the United States, the opioid epidemic is an extensive ongoing overuse of opioid medications, both from 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 great majority of Americans who use prescription opioids do not believe that they are misusing them.
SUPPORT for Patients and Communities Act, also known as Substance Use–Disorder Prevention that Promotes Opioid Recovery and Treatment for Patients and Communities Act, is a United States federal law, enacted during the 115th United States Congress, to make medical treatment for opioid addiction more widely available while also cracking down on illicit drugs. This piece of legislation is part of the ongoing conflict to stop and prevent the opioid epidemic in the United States. President Trump signed the bill on October 24, 2018.
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.
Clinical Opiate Withdrawal Scale (COWS) is a method used by registered practitioners to measure the severity of a patient's opioid withdrawal symptoms. This method consists of a series of 11 topics each comprising 4 - 5 common symptoms experienced by a patient undergoing opioid withdrawal. In each topic a rank is given depending on what the patient responds to. Generally, 0 is considered to be no symptom shown and 4 or 5 is considered to be the most common and severe symptom shown. These results are then added up and a final diagnosis is made based on the value obtained. This test is crucial as it allows the practitioner to assess the physiological and psychological behaviours of the patient as well as the severity of each symptom during the duration of the examination. The results are grouped into 3 categories of mild, moderately severe and severe. Mild consists of 5 to 12 points, moderately severe consists of 13 to 24 points and anything above 36 points is severe and requires direct medical attention.
Opioid agonist therapy (OAT) is a treatment in which prescribed opioid agonists are given to patients who live with Opioid use disorder (OUD). The benefits of this treatment include a more manageable withdrawal experience, cognitive improvement, and lower HIV transmission. The length of OAT varies from one individual to another based on their physiology, environmental surroundings, and quality of life.
Prescription drug addiction is the chronic, repeated use of a prescription drug in ways other than prescribed for, including using someone else’s prescription. A prescription drug is a pharmaceutical drug that may not be dispensed without a legal medical prescription. Drugs in this category are supervised due to their potential for misuse and substance use disorder. The classes of medications most commonly abused are opioids, central nervous system (CNS) depressants and central nervous stimulants. In particular, prescription opioid is most commonly abused in the form of prescription analgesics.
The Modernizing Opioid Treatment Access Act is a proposed United States congressional bill introduced in the 118th United States Congress. Introduced in response to the national opioid epidemic, the legislation would expand access to methadone, an approved medication for treating opioid use disorder (OUD).
