Prohibition of drugs in the context of "Sumptuary law"

A controlled substance is generally a drug or chemical whose manufacture, possession, and use is regulated by a government, such as illicitly-obtained drugs or prescription medications that are designated by law. Some treaties, notably the Single Convention on Narcotic Drugs, the Convention on Psychotropic Substances, and the United Nations Convention Against Illicit Traffic in Narcotic Drugs and Psychotropic Substances, provide internationally agreed-upon "schedules" of controlled substances, which have been incorporated into national laws; however, national laws usually significantly expand on these international conventions.

Some precursor chemicals used for the illegal production of 'controlled drugs' are also controlled substances in many countries, even though they may lack the pharmacological effects of the drugs themselves. Substances are classified according to schedules and consist primarily of potentially psychoactive substances and anabolic steroids. The controlled substances do not include many prescription items such as antibiotics.

Drug liberalization is a drug policy process of decriminalizing, legalizing, or repealing laws that prohibit the production, possession, sale, or use of prohibited drugs. Variations of drug liberalization include drug legalization, drug relegalization, and drug decriminalization. Proponents of drug liberalization may favor a regulatory regime for the production, marketing, and distribution of some or all currently illegal drugs in a manner analogous to that for alcohol, caffeine and tobacco.

Proponents of drug liberalization argue that the legalization of drugs would eradicate the illegal drug market and reduce the law enforcement costs and incarceration rates. They frequently argue that prohibition of recreational drugs—such as cannabis, opioids, cocaine, amphetamines and hallucinogens—has been ineffective and counterproductive and that substance use is better responded to by implementing practices for harm reduction and increasing the availability of addiction treatment. Additionally, they argue that relative harm should be taken into account in the regulation of drugs. For instance, they may argue that addictive or dependence-forming substances such as alcohol, tobacco and caffeine have been a traditional part of many cultures for centuries and remain legal in most countries, although other drugs which cause less harm than alcohol, caffeine or tobacco are entirely prohibited, with possession punishable with severe criminal penalties.

Social conservatism in the United States is a political ideology focused on the preservation of traditional values and beliefs. It focuses on a concern with moral and social values which proponents of the ideology see as degraded in modern society by liberalism. In the United States, one of the largest forces of social conservatism is the Christian right.

Social conservatives in the United States generally take fundamentalist, familialist, moralist stances on social issues. This is exemplified by their opposition to abortion, opposition to feminism, support for traditional family values, opposition to pornography, support for abstinence-only sex education, opposition to LGBT rights, support for school prayer, support for school vouchers, support for homeschooling, support for Sunday blue laws, opposition to gambling, and opposition to recreational drug use, among others.

The war on drugs, sometimes referred to in the 21st century as the war on cartels in contexts of military intervention and counterterrorism, is a global anti-narcotics campaign led by the United States federal government, including drug prohibition and foreign assistance, with the aim of reducing the illegal drug trade in the US. The initiative's efforts includes policies intended to discourage the production, distribution, and consumption of psychoactive drugs that the participating governments, through United Nations treaties, have made illegal.

The term "war on drugs" was popularized by the media after a press conference, given on June 17, 1971, during which President Richard Nixon declared drug abuse "public enemy number one". Earlier that day, Nixon had presented a special message to the US Congress on "Drug Abuse Prevention and Control", which included text about devoting more federal resources to the "prevention of new addicts, and the rehabilitation of those who are addicted"; that aspect did not receive the same media attention as the term "war on drugs".

Barbiturates are a class of depressant drugs that are chemically derived from barbituric acid. They are effective when used medically as anxiolytics, hypnotics, and anticonvulsants, but have physical and psychological addiction potential as well as overdose potential among other possible adverse effects. They have been used recreationally for their anti-anxiety and sedative effects, and are thus controlled in most countries due to the risks associated with such use.

Barbiturates have largely been replaced by benzodiazepines and nonbenzodiazepines ("Z-drugs") in routine medical practice, particularly in the treatment of anxiety disorders and insomnia, because of the significantly lower risk of overdose, and the lack of an antidote for barbiturate overdose. Despite this, barbiturates are still in use for various purposes: in general anesthesia, epilepsy, treatment of acute migraines or cluster headaches, acute tension headaches, euthanasia, capital punishment, and assisted suicide.
