According to addiction researcher Martin A. Plant, some people go through a period of self-redefinition before initiating recreational drug use.<ref name=plant1980/> They tend to view using drugs as part of a general lifestyle that involves belonging to a subculture that they associate with heightened status and the challenging of social norms.<ref name=plant1980/> Plant states: "From the user's point of view there are many positive reasons to become part of the milieu of drug taking. The reasons for drug use appear to have as much to do with needs for friendship, pleasure and status as they do with unhappiness or poverty. Becoming a drug taker, to many people, is a positive affirmation rather than a negative experience".<ref name=plant1980/>

[[Anthropology|Anthropological research]] has suggested that humans "may have evolved to counter-exploit plant [[neurotoxin]]s". The ability to use botanical chemicals to serve the function of [[endogenous]] [[neurotransmitter]]s may have improved survival rates, conferring an evolutionary advantage. A typically restrictive prehistoric diet may have emphasized the apparent benefit of consuming [[psychoactive drug]]s, which had themselves evolved to imitate neurotransmitters.<ref>{{cite journal |vauthors=Sullivan RJ, Hagen EH, Hammerstein P |date=June 2008 |title=Revealing the paradox of drug reward in human evolution |url=https://anthro.vancouver.wsu.edu/documents/293/Sullivan_et_al_2008_Revealing_the_paradox_of_drug_reward_in_human_evolution_yZX1BuS.pdf |url-status=live |editor-last=Barrett |editor-first=S |editor-link=Spencer Barrett (evolutionary biologist) |journal=[[Proceedings.

Drug harmfulness is defined as the degree to which a [[psychoactive drug]] has the potential to cause harm to the user and is measured in several ways, such as by [[Substance use disorder|addictiveness]] and the potential for physical harm. More objectively harmful drugs may be colloquially referred to as "hard drugs",<ref name=hardaz>{{cite book |title=The A-Z Encyclopedia of Alcohol and Drug Abuse |url=https://archive.org/details/azencyclopediaal00nord |url-access=limited |author=Thomas Nordegren |year=2002 |isbn=1-58112-404-X |page=[https://archive.org/details/azencyclopediaal00nord/page/n326 327] |publisher=[[Brown Walker Press]] |location=Parkland, Fla.}}</ref> and less harmful drugs as "soft drugs".<ref name=softaz>{{cite book |title=The A-Z Encyclopedia of Alcohol and Drug Abuse |url=https://archive.org/details/azencyclopediaal00nord|url-access=limited |author=Thomas Nordegren |year=2002 |isbn=1-58112-404-X |page=[https://archive.org/details/azencyclopediaal00nord/page/n596 597] |publisher=Brown Walker Press |location=Parkland, Fla.}}</ref> The term "soft drug" is considered controversial by critics as it may imply the false belief that soft drugs cause lesser or insignificant harm.<ref name=softaz/>

===Responsible use===
{{Main|Responsible drug use}}
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, through cartoons explaining responsible drug use and the consequences of irresponsible drug use to users.<ref>{{cite book | vauthors = Faupel CE, Horowitz AM, Weaver GS | title = The Sociology of American Drug Use | date = 2004 | publisher = McGraw-Hill Higher Education | location = Boston | isbn = 978-0-07-240683-2 | pages = 366 }}</ref> Another issue is that the illegality of drugs causes social and economic consequences for users—the drugs may be "cut" with adulterants and the purity varies wildly, making overdoses more likely—and legalization of drug production and distribution could reduce these and other dangers of illegal drug use.<ref>{{cite news |url= http://www.economist.com/printedition/displayStory.cfm?Story_ID=13237193 |title=Failed states and failed policies, How to stop the drug wars |access-date=10 March 2009 |date=5 March 2009 |newspaper=The Economist}}</ref>

The prevalence of recreational drugs in human societies is widely reflected in fiction, entertainment, and the arts, subject to prevailing laws and social conventions. For instance, in the [[music industry]], the musical genres [[Hip hop music|hip hop]], [[Hardcore hip hop|hardcore rap]], and [[Trap music|trap]], alongside their [[List of hip hop genres|derivative subgenres]] and [[subculture]]s, are most notorious for having continuously celebrated and promoted [[Illegal drug trade|drug trafficking]], [[Gangster|gangster lifestyle]], and consumption of alcohol and other drugs since their inception in the United States during the late 1980s–early 1990s.<ref>{{cite web |last=Gonzales |first=Matt |date=2 March 2020 |origyear=27 November 2017 |title=Rap Culture's Evolution from Glorifying to Decrying Drug Use |url=https://www.drugrehab.com/featured/substance-use-and-rap-music/ |url-status=live |location=[[Orlando, Florida]] |publisher=DrugRehab.com |archive-url=https://web.archive.org/web/20210116094555/https://www.drugrehab.com/featured/substance-use-and-rap-music/ |archive-date=16 January 2021 |access-date=10 January 2022}}</ref><ref>{{cite magazine |author-last=Granovsky |author-first=Josh |date=23 November 2018 |title=Emo rap needs to end |url=https://www.queensjournal.ca/story/2018-11-23/pop-culture/emo-rap-needs-to-end/ |url-status=live |magazine=[[The Queen's Journal]] |location=[[Kingston, Ontario]] |publisher=[[Alma Mater Society of Queen's University]] |archive-url=https://web.archive.org/web/20210724213024/https://www.queensjournal.ca/story/2018-11-23/pop-culture/emo-rap-needs-to-end/ |archive-date=24 July 2021 |access-date=7 August 2022}}</ref><ref>{{cite journal |author-last=Smiley |author-first=Calvin J. |year=2017 |title=Addict Rap?: The Shift from Drug Distributor to Drug Consumer in Hip Hop |url=https://scholarscompass.vcu.edu/cgi/viewcontent.cgi?article=1062&context=jhhs |url-status=live |format=PDF |journal=Journal of Hip Hop Studies |location=[[Richmond, Virginia]] |publisher=VCU Scholars Compass ([[Virginia Commonwealth University]]) |volume=4 |issue=1 |pages=1–24 |doi=10.34718/ZBWC-RN03 |doi-access=free |issn=2331-5563 |archive-url=https://web.archive.org/web/20210706234554/https://scholarscompass.vcu.edu/cgi/viewcontent.cgi?article=1062&context=jhhs |archive-date=6 July 2021 |access-date=10 January 2022}}</ref> In [[video games]], for example, drugs are portrayed in a variety of ways: including power-ups ([[cocaine]] gum replenishes stamina in ''[[Red Dead Redemption 2]]''), obstacles to be avoided (such as the Fuzzies in ''[[Super Mario World 2: Yoshi's Island]]'' that distort the player's view when accidentally consumed), items to be bought and sold for in-game currency (coke dealing is a big part of ''[[Scarface: The World Is Yours]]'').

* [[Cannabis (drug)|Cannabis]]: Its common forms include [[marijuana]] and [[hashish]], which are smoked, vaporized or eaten. It contains at least 85 [[cannabinoid]]s. The primary [[psychoactive]] component is [[THC]], which mimics the neurotransmitter [[anandamide]], named after the [[Hindu]] ''ananda'', "joy, bliss, delight". When cannabis is eaten, THC metabolized into [[11-OH-THC]], this molecule is the primary psychoactive compound of edible forms of cannabis. [[THC]] and [[11-OH-THC]] are [[partial agonist]] at [[Cannabinoid receptor 1|CB1]] and [[Cannabinoid receptor type 2|CB2]] receptors of the [[endocannabinoid system]].

LSD (d-Lysergic Acid Diethylamide) is a molecule of the [[lysergamide]] family, a subclass of the [[tryptamine]] family. 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.

* [[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 (whippets or whip-its) (see [[inhalant]]), as it causes perceptual effects, a "high" and at higher doses, hallucinations.
* [[Opiates]] and [[opioids]]: Available by prescription for pain relief. Commonly used opioids include [[oxycodone]], [[hydrocodone]], [[codeine]], [[fentanyl]], [[heroin]], [[methadone]], and [[morphine]]. Opioids have a high potential for [[addiction]] and have the ability to induce severe physical [[Drug withdrawal|withdrawal]] symptoms upon cessation of frequent use.

==Routes of administration==
[[File:Caffeineinsufflation.JPG|thumb|[[Insufflation (medicine)|Insufflation]] of powdered drug]]
[[File:Injecting Heroin.JPG|thumb|[[Drug injection|Injection]] of heroin]]

Drugs are often associated with a particular [[route of administration]]. Many drugs can be consumed in more than one way. For example, [[marijuana]] can be swallowed like food or smoked, and [[cocaine]] can be "sniffed" in the nostrils, injected, or, with various modifications, smoked.

* [[inhalation]]: all intoxicative inhalants (see below) that are gases or solvent vapours that are inhaled through the trachea, as the name suggests
* [[Insufflation (medicine)|insufflation]]: also known as "snorting", or "sniffing", this method involves the user placing a powder in the nostrils and breathing in through the nose, so that the drug is absorbed by the [[mucous membranes]]. Drugs that are "snorted", or "sniffed", include [[History and culture of substituted amphetamines|powdered amphetamines]], [[cocaine]], [[heroin]], [[ketamine]], [[MDMA]], and [[Snuff (tobacco)|snuff tobacco]].
* [[Subcutaneous injection]] (see also the article [[Skin popping]]): injection of drug into the third lowest layer of skin.
* [[Intramuscular injection]]: injection of drug into a muscle.
* [[intravenous injection]] (see also the article [[Drug injection]]): the user injects a solution of water and the drug into a vein, or less commonly, into the tissue.<ref name="Wang-Maher 2019"/> Drugs that are injected include [[morphine]] and [[heroin]],<ref name="Wang-Maher 2019"/> less commonly other opioids. Stimulants like [[cocaine]] or [[methamphetamine]] may also be injected.<ref name="Wang-Maher 2019"/> In rare cases, users inject other drugs.
* oral intake: caffeine, ethanol, cannabis edibles, psilocybin mushrooms, [[coca tea]], [[poppy tea]], [[laudanum]], [[Gamma-hydroxybutyrate|GHB]], ecstasy pills with [[MDMA]] or various other substances (mainly stimulants and psychedelics), prescription and over-the-counter drugs (ADHD and narcolepsy medications, benzodiazepines, anxiolytics, sedatives, cough suppressants, morphine, codeine, opioids and others)
* [[Sublingual administration|sublingual]]: substances diffuse into the [[blood]] through [[Tissue (biology)|tissues]] under the tongue.  Many psychoactive drugs can be or have been specifically designed for sublingual administration, including [[barbiturate]]s, benzodiazepines,<ref>{{Cite web|url=http://home.intekom.com/pharm/akromed/ativansl.html | archive-url = https://web.archive.org/web/20040204200938/http://home.intekom.com/pharm/akromed/ativansl.html | archive-date = 4 February 2004 |title= Ativan 1 mg Sublingual Tablets | work = Malahyde Information Systems | date = 3 May 1985 | access-date = 8 July 2016 }}</ref> [[opioid]] [[analgesics]] with poor gastrointestinal bioavailability, [[LSD]] blotters, [[Coca plant|coca]] leaves, some hallucinogens. This route of administration is activated when chewing some forms of [[smokeless tobacco]] (e.g. [[dipping tobacco]], [[snus]]).
* [[Rectal (medicine)|intrarectal]]: administering into the rectum, most water-soluble drugs can be used this way.
* [[smoking]] (see also the section below): tobacco, cannabis, [[opium]], [[Methamphetamine|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]].<ref>{{Citation |last1=Ruiz |first1=María Esperanza |title=Routes of Drug Administration |date=2018 |url=http://link.springer.com/10.1007/978-3-319-99593-9_6 |work=ADME Processes in Pharmaceutical Sciences |pages=97–133 |editor-last=Talevi |editor-first=Alan |place=Cham |publisher=Springer International Publishing |language=en |doi=10.1007/978-3-319-99593-9_6 |isbn=978-3-319-99592-2 |access-date=2022-03-27 |last2=Scioli Montoto |first2=Sebastián |editor2-last=Quiroga |editor2-first=Pablo A.

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]].

{{Further|Depressant}}
Depressants are psychoactive drugs that temporarily diminish the function or activity of a specific part of the body or mind.<ref name="urlMSDS Glossary">{{cite web |url= http://www.utexas.edu/safety/ehs/msds/glossary/?page=d | title = Depressant | date =  30 August 2007 | work = MSDS Glossary | publisher = Environmental Health and Safety, University of Texas at Austin |access-date= 1 January 2009 |url-status= dead |archive-url= https://web.archive.org/web/20090117220900/http://www.utexas.edu/safety/ehs/msds/glossary/?page=d |archive-date= 17 January 2009}}</ref> Colloquially, depressants are known as "downers", and users generally take them to feel more relaxed and less tense. Examples of these kinds of effects may include anxiolysis, sedation, and hypotension. Depressants are widely used throughout the world as [[prescription medicine]]s and as [[prohibition (drugs)|illicit substances]]. When these are used, effects may include [[anxiolysis]] (reduction of anxiety), [[analgesia]] (pain relief), [[sedation]], [[somnolence]], cognitive/memory impairment, [[dissociation (psychology)|dissociation]], muscle relaxation, lowered [[blood pressure]]/[[heart rate]], [[respiratory depression]], [[anesthesia]], and [[anticonvulsant]] effects.  Depressants exert their effects through a number of different pharmacological mechanisms, the most prominent of which include potentiation of [[GABA]] or [[opioid]] activity, and inhibition of [[adrenergic]], [[histamine]] or [[acetylcholine]] activity. Some are also capable of inducing feelings of [[euphoria]]. The most widely used depressant by far is [[alcohol (drug)|alcohol]] (i.e. [[ethanol]]).

Stimulants or "uppers", such as [[amphetamines]] or [[cocaine]], which increase mental or physical function, have an opposite effect to depressants.

Depressants, in particular alcohol, can precipitate [[Substance-induced psychosis|psychosis]]. A 2019 systematic review and meta-analysis by Murrie et al. found that the rate of transition from opioid, alcohol and [[sedative]] induced psychosis to schizophrenia was 12%, 10% and 9% respectively.<ref name="Transition of Substance-Induced, Br">{{cite journal | vauthors = Murrie B, Lappin J, Large M, Sara G | title = Transition of Substance-Induced, Brief, and Atypical Psychoses to Schizophrenia: A Systematic Review and Meta-analysis | journal = Schizophrenia Bulletin | volume = 46 | issue = 3 | pages = 505–516 | date = April 2020 | pmid = 31618428 | pmc = 7147575 | doi = 10.1093/schbul/sbz102 | doi-access = free }}</ref>

====Antihistamines====
{{Further|Antihistamine}}
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 [[H1 antagonist|classical antihistamines]] that act upon the [[histamine H1 receptor|H<sub>1</sub> 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.{{Citation needed|date=July 2020}} High dosages taken to induce recreational drug effects may lead to overdoses. Antihistamines are also consumed in combination with alcohol, particularly by youth who find it hard to obtain alcohol. The combination of the two drugs can cause intoxication with lower alcohol doses.

Hallucinations and possibly delirium resembling the effects of [[Datura stramonium]] can result if the drug is taken in much higher than therapeutic doses. Antihistamines are widely available over the counter at drug stores (without a prescription), in the form of allergy medication and some [[cough medicine]]s. 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 extend and intensify the effects of opioids and depressants. The most commonly used are [[hydroxyzine]], mainly to extend 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 observed.

====Analgesics====
{{Further|Analgesic}}
Analgesics (also known as "painkillers") are used to relieve [[pain]] (achieve [[wikt:analgesia|analgesia]]). The word ''analgesic'' derives from Greek "αν-" (''an-'', "without") and "άλγος" (''álgos'', "pain"). Analgesic drugs act in various ways on the [[peripheral nervous system|peripheral]] and [[central nervous system|central]] nervous systems; they include [[paracetamol]] (also known in the US as acetaminophen), the [[nonsteroidal anti-inflammatory drug]]s (NSAIDs) such as the [[salicylate]]s (e.g. [[aspirin]]), and [[opioid]] drugs such as [[hydrocodone]], [[codeine]], [[heroin]] and [[oxycodone]]. Some further examples of the [[Brand|brand name]] [[prescription medication|prescription]] [[opiate]]s 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).

====Tranquilizers====
{{Further|Tranquilizer}}
The following are examples of tranquilizers ([[gamma-Aminobutyric acid#GABAergic drugs|GABAergics]]):
* [[Barbiturate]]s
* [[Benzodiazepine]]s
* [[Ethanol]] (drinking alcohol; ethyl alcohol)
* [[Nonbenzodiazepine]]s

===Stimulants===
{{Further|Stimulant}}
[[File:Cocaine lines 2.jpg|thumb|right|[[Cocaine]] is a commonly used [[stimulant]].]]
Stimulants, also known as "psychostimulants",<ref name="dorlands">{{cite web |url=http://www.mercksource.com/pp/us/cns/cns_hl_dorlands_split.jsp?pg=/ppdocs/us/common/dorlands/dorland/seven/000088218.htm |title= Psychostimulant | work = Dorlands Medical Dictionary }}</ref> induce [[euphoria]] with improvements in mental and physical function, such as enhanced alertness, wakefulness, and locomotion. Stimulants are also occasionally called "uppers". [[Depressant]]s or "downers", which decrease mental or physical function, are in stark contrast to stimulants and are considered to be their functional opposites.

Stimulants enhance the activity of the [[central nervous system|central]] and [[peripheral nervous system]]s. Common effects may include increased [[alertness]], [[awareness]], [[wakefulness]], [[endurance]], [[productivity]], and [[motivation]], [[arousal]], [[animal locomotion|locomotion]], [[heart rate]], and [[blood pressure]], and a diminished desire for [[food]] and [[sleep]].

Use of stimulants may cause the body to significantly reduce its production of endogenous compounds that fulfill similar functions. Once the effect of the ingested stimulant has worn off the user may feel depressed, lethargic, confused, and dysphoric. This is colloquially termed a "crash" and may promote reuse of the stimulant.

Amphetamines are a significant cause of drug-induced psychosis. Importantly, a 2019 meta-analysis found that 22% of people with amphetamine-induced psychosis transition to a later diagnosis of schizophrenia.<ref name="Transition of Substance-Induced, Br"/>

Examples of stimulants include:
* [[Sympathomimetic]]s ([[catecholaminergic]]s)—e.g. [[amphetamine]], [[methamphetamine]], [[cocaine]], [[methylphenidate]], [[ephedrine]], [[pseudoephedrine]]
* [[Entactogen]]s ([[Serotonin|serotonergic]]s, primarily phenethylamines)—e.g. [[MDMA]] (which is also an amphetamine)
* [[Eugeroics]], e.g. [[modafinil]]
* Others
** [[arecoline]] (found in ''[[Areca catechu]]'')
** [[caffeine]] (found in ''[[Coffea|Coffea spp.]]'')
** [[nicotine]] (found in ''[[Nicotiana|Nicotiana spp.]]'')
** [[rauwolscine]] (found in ''[[Rauvolfia serpentina]]'')
** [[yohimbine]] (Procomil; a tryptamine alkaloid found in ''[[Pausinystalia johimbe]]'')

===Euphoriants===

* [[Cannabis]]: [[Tetrahydrocannabinol]], the main psychoactive ingredient in this plant, can have sedative and euphoric properties.
* 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.<ref>{{cite book| vauthors = Foster S |title=A field guide to Western Medicinal Plants and Herbs|year=2002|publisher=Houghton Mifflin Company|location=New York|pages=58|url=https://books.google.com/books?id=tg_bPUzhJ9oC|isbn=978-0395838068}}</ref>

===Hallucinogens===
{{Further|Hallucinogen}}
{{See also|List of psychedelic drugs}}
Hallucinogens can be divided into three broad categories: [[psychedelic drug|psychedelic]]s, [[dissociative]]s, and [[deliriant]]s. 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 [[dream]]s.

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]].

Hallucinogen-induced psychosis occurs when psychosis persists despite no longer being intoxicated with the drug. It is estimated that 26% of people with hallucinogen-induced psychosis will transition to a diagnosis of schizophrenia. This percentage is less than the psychosis transition rate for cannabis (34%) but higher than that of amphetamines (22%).<ref name="Transition of Substance-Induced, Br"/>

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 [[clinical depression|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.
