Recreational drug use
Recreational drug use is the use of a drug (legal, controlled, or illegal) with the primary intention to alter the state of consciousness (through alteration of the central nervous system) in order to create positive emotions and feelings. The popular concept of this phenomenon puts it closer to a social behaviour that many places around the world tolerate rather than to serious medical conditions such as self-medication. When a substance enters the user's body, it brings on an intoxicating effect; in terms of psychoactive drugs, such as cannabis or MDMA, this is often referred to as a "high".
Recreational drug use has been associated by some[by whom?] with various dispositions such as curiosity, boredom, low self-esteem, desire for risk, for meditation, desire to escape from or cope with difficulties, to relax, to increase energy, and to improve focus, concentration, or creativity. Psychological disorders such as depression, trauma, social anxiety, and schizophrenia have also been claimed by some people[by whom?] to be promoters of drug use. Some users seek to encourage their socializing or an aphrodisiac effect.
Drugs commonly considered capable of recreational use include ethanol, cannabis, nicotine, caffeine, and controlled substances within the scope of the United Nations' Single Convention on Narcotic Drugs and Convention on Psychotropic Substances. In 2009 it was estimated that about 3% to 6% of people aged 15 to 65 had used illegal drugs at least once (149 to 270 million). International and domestic law enforcement agencies are perpetually occupied with interdiction efforts against illegal drug use, manufacture, and distribution.

Genetic research has indicated that man and his distant ancestors "may have evolved to counter-exploit plant neurotoxins". The ability to use botanical chemicals to serve the function of endogenous neurotransmitters may have improved the survival rate, conferring an evolutionary advantage. A typically restrictive prehistoric diet may have emphasised the apparent benefit of consuming psychoactive drugs, which had themselves evolved to imitate neurotransmitters.
"Emerging insights from plant evolutionary ecology and the genetics of hepatic enzymes, particularly cytochrome P450" have led researchers to believe that "humans have shared a co-evolutionary relationship with psychoactive plant substances for millions of years".
The concept of "responsible drug use" is that a person can use drugs recreationally or otherwise with reduced or eliminated risk of negatively affecting other aspects of one's life or other people's lives. Advocates of this philosophy point to the many well-known artists and intellectuals who have used drugs, experimentally or otherwise, with few detrimental effects on their lives. Responsible drug use becomes problematic only when the use of the substance significantly interferes with the user's daily life.
Responsible drug use advocates that users should not take drugs at the same time as activities such as driving, swimming, operating machinery, or other activities that are unsafe without a sober state. Responsible drug use is emphasized as a primary prevention technique in harm-reduction drug policies. Harm-reduction policies were popularized in the late 1980s, although they began in the 1970s counter-culture, when cartoons explaining responsible drug use and the consequences of irresponsible drug use were distributed to users. Another issue is that the illegality of drugs in itself may also cause social and economic consequences for those using them—the drugs may be "cut" with adulterants and the purity varies wildly, making overdoses more likely—and legalization of drug production and distribution would reduce these and other dangers of illegal drug use. Harm reduction seeks to minimize the harm that can occur through the use of various drugs, whether legal (e.g., alcohol and nicotine), or illegal (e.g., heroin and cocaine). For example, people who inject illicit drugs can minimize harm to both themselves and members of the community through proper injecting technique, using new needles and syringes each time, and proper disposal of all injecting equipment.
The amount and type of risks that come with recreational drug use vary widely with the drug and the amount being used. There are many factors in the environment and the user that interact with each drug differently. Overall, some studies suggest that alcohol is one of the most dangerous of all recreational drugs; only heroin, crack cocaine, and methamphetamines are judged to be more harmful. However, studies which focus on a moderate level of alcohol consumption have concluded that there can be substantial health benefits from its use, such as decreased risk of cardiac disease, stroke and cognitive decline. Experts in the UK offer that some drugs that may be causing less harm, to fewer users (although they are also used less frequently in the first place) include Cannabis, psilocybin mushrooms, LSD, and ecstasy. These drugs are not without their own particular risks.
The following substances, all widely illegal unless stated otherwise, are here listed by order of world-wide popularity:
- alcohol: Most drinking alcohol is ethanol, CH
2OH, produced by the fermentation of sugars by yeasts to create wine, beer, and distilled liquor. In most areas of the world it is legal for those over a certain age (typically 18–21). It is an IARC 'Group 1' carcinogen and a teratogen.
- amphetamines: Prescribed for ADHD, narcolepsy, depression and weight loss. A potent central nervous system stimulant, in the 1940s and 50s methamphetamine was used by Axis and Allied troops in World War II, and, later on, other armies, and by Japanese factory workers. It increases muscle strength and fatigue resistance and improves reaction time. Methamphetamine use can be neurotoxic, which means it damages dopamine neurons. As a result of this brain damage, chronic use can lead to post acute withdrawal syndrome.
- cannabis: Its common forms include marijuana and hashish, which are smoked or eaten. It contains at least 85 cannabinoids. The primary psychoactive component is THC, which mimics the neurotransmitter anandamide, named after the Hindu ananda, "joy, bliss, delight." The review article Campbell & Gowran (2007) states that "manipulation of the cannabinoid system offers the potential to upregulate neuroprotective mechanisms while dampening neuroinflammation. Whether these properties will be beneficial in the treatment of Alzheimer's disease in the future is an exciting topic that undoubtedly warrants further investigation."
- caffeine: A legal drug, often from coffee, tea, energy drinks, some soft drinks, and chocolate.
- cocaine: It is available as a powder, which is insufflated or injected. A popular derivative, crack cocaine is typically smoked. When transformed into its freebase form, crack, the cocaine vapour may be inhaled directly. This is thought to increase bioavailability, but has also been found to be toxic, due to the production of methylecgonidine during pyrolysis.
- MDMA: Commonly known as "Ecstasy", it is a common club drug in the rave scene.
- ketamine: used by paramedics in emergency situations for its dissociative and analgesic qualities and illegally in the club drug scene
- LSD: A popular ergoline derivative, that was first synthesized in 1938 by Hofmann. However, he failed to notice its psychedelic potential until 1943. In the 1950s, it was used in psychological therapy, and, covertly, by the CIA in Project MKULTRA, in which the drug was administered to unwitting US and Canadian citizens. It played a central role in 1960s 'counter-culture', and was banned in October 1968 by US President Lyndon B Johnson.
- nitrous oxide: legally used by dentists as an anxiolytic and anaesthetic, it is also used recreationally by users who obtain it from whipped cream canisters (see inhalant).
- opiates and opioids: Available by prescription.
- psilocybin mushrooms: Until 1963, when it was chemically analysed by Albert Hofmann, it was completely unknown to modern science that psilocybe semilanceata ("Liberty Cap", common throughout Europe) contains psilocybin, a hallucinogen previously identified only in species native to Mexico, Asia, and North America.
- tobacco: Nicotiana tabacum. A legal drug contained in tobacco leaves, which are either smoked, chewed or snuffed. It contains nicotine, which crosses the blood–brain barrier in 10–20 seconds. It mimics the action of the neurotransmitter acetylcholine at nicotinic acetylcholine receptors in the brain and the neuromuscular junction. The neuronal forms of the receptor are present both post-synaptically (involved in classical neurotransmission) and pre-synaptically, where they can influence the release of multiple neurotransmitters.
- tranquilizers: barbiturates, benzodiazepines (commonly prescribed for anxiety; known to cause dementia and post acute withdrawal syndrome)
- Bath salts: Mephedrone/Methylenedioxypyrovalerone (MDPV)
- DMT – primary ingredient in ayahuasca, can also be smoked in a crack pipe; briefly (c. 30 minutes) causes a "total loss of connection to external reality"
- Peyote: Contains mescaline, native to southwestern Texas and Mexico
- salvia divinorum: hallucinogenic Mexican herb in the mint family; not considered recreational, most likely due to the nature of the hallucinations (legal)
- Synthetic cannabis: Spice, K2, JWH-018, AM-2201
- research chemicals: 2C variants, etc.
Routes of administration
Drugs most often associated with a particular route of administration:
- inhalation: all inhalants (listed above), as the name suggests
- insufflation: amphetamines, cocaine, heroin, ketamine and MDMA.
- chewing, absorbing sublingually, placing under the lip, etc. – some forms of smokeless tobacco (e.g. dipping tobacco, snus), LSD blotters, coca leaves, some hallucinogens
- intravenous injection (see also the article Drug injection): morphine and heroin, less commonly other opioids or stimulants like cocaine or methamphetamine.
- oral intake: caffeine, ethanol, cannabis edibles, psilocybin mushrooms, coca tea, poppy tea, laudanum, GHB, ecstasy pills with MDMA and/or various other substances (mainly stimulants and psychedelics), prescription and over-the-counter drugs (ADHD and narcolepsy medications, benzodiazapines, anxiolytics, sedatives, cough suppressants, morphine, codeine, opioids and others)
- intrarectal: administering into the rectum, most water-soluble drugs can be used this way
- smoking (see also the section below): tobacco, cannabis, opium, crystal meth, phencyclidine, crack cocaine and heroin (diamorphine as freebase) known as chasing the dragon
- transdermal patches with prescription drugs: e.g. methylphenidate (Daytrana) and fentanyl
Many drugs are taken through various routes. Intravenous route is the most efficient, but also one of the most dangerous. Nasal, rectal, inhalation and smoking are safer. The oral route is one of the safest and most comfortable, but of little bioavailability.

Depressants are psychoactive drugs that temporarily diminish the function or activity of a specific part of the body or mind. Examples of these kinds of effects may include anxiolysis, sedation, and hypotension. Due to their effects typically having a "down" quality to them, depressants are also occasionally referred to as "downers". Stimulants or "uppers", which increase mental and/or physical function, are in stark contrast to depressants and are considered to be their functional opposites. Depressants are widely used throughout the world as prescription medicines and as illicit substances. When these are used, effects may include anxiolysis, analgesia, sedation, somnolence, cognitive/memory impairment, dissociation, muscle relaxation, lowered blood pressure/heart rate, respiratory depression, anesthesia, and anticonvulsant effects. Some are also capable of inducing feelings of euphoria. Depressants exert their effects through a number of different pharmacological mechanisms, the most prominent of which include facilitation of GABA and/or opioid activity, and inhibition of adrenergic, histamine and/or acetylcholine activity.
Antihistamines (or "histamine antagonists") inhibit the release or action of histamine. "Antihistamine" can be used to describe any histamine antagonist, but the term is usually reserved for the classical antihistamines that act upon the H1 histamine receptor. Antihistamines are used as treatment for allergies. Allergies are caused by an excessive response of the body to allergens, such as the pollen released by grasses and trees. An allergic reaction causes release of histamine by the body. Other uses of antihistamines are to help with normal symptoms of insect stings even if there is no allergic reaction. Their recreational appeal exists mainly due to their anticholinergic properties, that induce anxiolysis and, in some cases such as diphenhydramine, chlorpheniramine, and orphenadrine, a characteristic euphoria at moderate doses.
Hallucinations and possibly delirium resembling the effects of Datura stramonium can result if the drug is taken in much higher than therapeutical dosages.
Antihistamines are widely available over the counter at drug stores (without a prescription), in the form of allergy medication and some cough medicines. They are sometimes used in combination with other substances such as alcohol. The most common unsupervised use of antihistamines in terms of volume and percentage of the total is perhaps in parallel to the medicinal use of some antihistamines to stretch out and intensify the effects of opioids and depressants. The most commonly used are hydroxyzine, mainly to stretch out a supply of other drugs, as in medical use, and the above-mentioned ethanolamine and alkylamine-class first-generation antihistamines, which are - once again as in the 1950s - the subject of medical research into their anti-depressant properties.
For all of the above reasons, the use of medicinal scopolamine for recreational uses is also seen.
Analgesics (also known as "painkillers") are used to relieve pain (achieve analgesia). The word analgesic derives from Greek "αν-" (an-, "without") and "άλγος" (álgos, "pain"). Analgesic drugs act in various ways on the peripheral and central nervous systems; they include paracetamol (para-acetylaminophenol, also known in the US as acetaminophen), the non-steroidal anti-inflammatory drugs (NSAIDs) such as the salicylates, and opioid drugs such as hydrocodone, codeine, heroin and oxycodone. Some further examples of the brand name prescription opiates and opioid analgesics that may be used recreationally include Vicodin, Lortab, Norco (hydrocodone), Avinza, Kapanol (morphine), Opana, Paramorphan (oxymorphone), Dilaudid, Palladone (hydromorphone), and OxyContin (oxycodone).

- Catnip Catnip contains a sedative known as nepetalactone that activates opioid receptors. In cats it elicits sniffing, licking, chewing, head shaking, rolling, and rubbing which are indicators of pleasure. In humans, however, catnip does not act as a euphoriant.
- Cannabis Tetrahydrocannabinol, the main psychoactive ingredient in this plant can have sedative and euphoric properties.
- Stimulants: "Psychomotor stimulants produce locomotor activity (the subject becomes hyperactive), euphoria, (often expressed by excessive talking and garrulous behaviour), and anorexia. The amphetamines are the best known drugs in this category..."
- MDMA: The "euphoriant drugs such as MDMA (‘ecstasy’) and MDEA (‘eve’)" are popular amongst young adults. MDMA "users experience short-term feelings of euphoria, rushes of energy and increased tactility."
- Opium: This "drug derived from the unripe seed-pods of the opium poppy…produces drowsiness and euphoria and reduces pain. Morphine and codeine are opium derivatives."
Hallucinogens can be divided into three broad categories: psychedelics, dissociatives, and deliriants. They can cause subjective changes in perception, thought, emotion and consciousness. Unlike other psychoactive drugs such as stimulants and opioids, hallucinogens do not merely amplify familiar states of mind but also induce experiences that differ from those of ordinary consciousness, often compared to non-ordinary forms of consciousness such as trance, meditation, conversion experiences, and dreams.
Psychedelics, dissociatives, and deliriants have a long worldwide history of use within medicinal and religious traditions. They are used in shamanic forms of ritual healing and divination, in initiation rites, and in the religious rituals of syncretistic movements such as União do Vegetal, Santo Daime, Temple of the True Inner Light, and the Native American Church. When used in religious practice, psychedelic drugs, as well as other substances like tobacco, are referred to as entheogens.
Starting in the mid-20th century, psychedelic drugs have been the object of extensive attention in the Western world. They have been and are being explored as potential therapeutic agents in treating depression, post-traumatic stress disorder, Obsessive-compulsive disorder, alcoholism, and opioid addiction. Yet the most popular, and at the same time most stigmatized, use of psychedelics in Western culture has been associated with the search for direct religious experience, enhanced creativity, personal development, and "mind expansion". The use of psychedelic drugs was a major element of the 1960s counterculture, where it became associated with various social movements and a general atmosphere of rebellion and strife between generations.

Stimulants, also known as "psychostimulants", induce euphoria with improvements in mental and physical function, such as enhanced alertness, wakefulness, and locomotion. Due to their effects typically having an "up" quality to them, stimulants are also occasionally referred to as "uppers". Depressants or "downers", which decrease mental and/or physical function, are in stark contrast to stimulants and are considered to be their functional opposites.
Stimulants enhance the activity of the central and peripheral nervous systems. Common effects may include increased alertness, awareness, wakefulness, endurance, productivity, and motivation, arousal, locomotion, heart rate, and blood pressure, and a diminished desire for food and sleep.
Use of stimulants may cause the body to reduce significantly its production of natural body chemicals that fulfill similar functions. Until the body reestablishes its normal state, once the effect of the ingested stimulant has worn off the user may feel depressed, lethargic, confused, and miserable. This is referred to as a "crash", and may provoke reuse of the stimulant.
- Sympathomimetics (catecholaminergics)—e.g. amphetamine, methamphetamine, cocaine, methylphenidate, ephedrine, pseudoephedrine
- Entactogens (serotonergics, primarily phenethylamines)—e.g. MDMA
- Eugeroics, e.g. modafinil
Inhalants are gases, aerosols, or solvents that are breathed in and absorbed through the lungs. While some "inhalant" drugs are used for medical purposes, as in the case of nitrous oxide, a dental anesthetic, inhalants are used as recreational drugs for their intoxicating effect. Most inhalant drugs that are used non-medically are ingredients in household or industrial chemical products that are not intended to be concentrated and inhaled, including organic solvents (found in cleaning products, fast-drying glues, and nail polish removers), fuels (gasoline (petrol) and kerosene), and propellant gases such as Freon and compressed hydrofluorocarbons that are used in aerosol cans such as hairspray, whipped cream, and non-stick cooking spray. A small number of recreational inhalant drugs are pharmaceutical products that are used illicitly, such as anesthetics (ether and nitrous oxide) and volatile anti-angina drugs (alkyl nitrites).
The most serious inhalant abuse occurs among children and teens who "[...] live on the streets completely without family ties." Inhalant users inhale vapor or aerosol propellant gases using plastic bags held over the mouth or by breathing from a solvent-soaked rag or an open container. The effects of inhalants range from an alcohol-like intoxication and intense euphoria to vivid hallucinations, depending on the substance and the dosage. Some inhalant users are injured due to the harmful effects of the solvents or gases, or due to other chemicals used in the products that they are inhaling. As with any recreational drug, users can be injured due to dangerous behavior while they are intoxicated, such as driving under the influence. Computer cleaning dusters are dangerous to inhale, because the gases expand and cool rapidly upon being sprayed. In some cases, users have died from hypoxia (lack of oxygen), pneumonia, cardiac failure or arrest, or aspiration of vomit.
- diethyl ether
- laughing gas (nitrous oxide)
- Poppers (alkyl nitrites)
- solvents and propellants (including propane, butane, freon, gasoline, kerosene, toluene) and the fumes of glues containing them
In efforts to curtail recreational drug use, governments worldwide introduced several laws prohibiting the possession of almost all varieties of recreational drugs during the 20th century. The West's "War on Drugs" however, is now facing increasing criticism. Evidence is insufficient to tell if behavioral interventions help prevent recreational drug use in children.
Alcohol is the most widely used drug in Australia tried one or more times in their lives by 86.2% of Australians aged 12 years and over, while 34.8% of Australians aged 12 years and over have used cannabis one or more times in their lives.
In the 1960s, the number of Americans who had tried cannabis at least once increased over twentyfold. In 1969, the FBI reported that between the years 1966 and 1968, the number of arrests for marijuana possession, which had been outlawed throughout the United States under Marihuana Tax Act of 1937, had increased by 98%. Despite acknowledgement that drug use was greatly growing among America's youth during the late 1960s, surveys have suggested that only as much as 4% of the American population had ever smoked marijuana by 1969. By 1972, however, that number would increase to 12%. That number would then double by 1977.
The Controlled Substances Act of 1970 classified marijuana along with heroin and LSD as a Schedule I drug, i.e., having the relatively highest abuse potential and no accepted medical use. Most marijuana at that time came from Mexico, but in 1975 the Mexican government agreed to eradicate the crop by spraying it with the herbicide paraquat, raising fears of toxic side effects. Colombia then became the main supplier. The "zero tolerance" climate of the Reagan and Bush administrations (1981–93) resulted in passage of strict laws and mandatory sentences for possession of marijuana and in heightened vigilance against smuggling at the southern borders. The "war on drugs" thus brought with it a shift from reliance on imported supplies to domestic cultivation (particularly in Hawaii and California). Beginning in 1982 the Drug Enforcement Administration turned increased attention to marijuana farms in the United States, and there was a shift to the indoor growing of plants specially developed for small size and high yield. After over a decade of decreasing use, marijuana smoking began an upward trend once more in the early 1990s, especially among teenagers, but by the end of the decade this upswing had leveled off well below former peaks of use.
Recreational drugs and culture
Many movements and organizations are advocating for or against the liberalization of the use of recreational drugs, notably cannabis legalization. Subcultures have emerged among users of recreational drugs, as well as among those who abstain from them, such as teetotalism and "straight edge".
The prevalence of recreational drugs in human societies is widely reflected in fiction, entertainment, and the arts, subject to prevailing laws and social conventions. In video games, for example, enemies are often drug dealers, a narrative device that justifies the player killing them. Other games portray drugs as a kind of "power-up"; their effect is often unrealistically conveyed by making the screen wobble and blur.
