==Society and culture==
===Counterculture===
By the mid-1960s, the youth [[counterculture]]s in California, particularly in San Francisco, had widely adopted the use of hallucinogenic drugs, including LSD. The first major underground LSD factory was established by [[Owsley Stanley]].<ref name=DeRogatispp8-9>{{cite book |vauthors=DeRogatis J |title=Turn On Your Mind: Four Decades of Great Psychedelic Rock |location=Milwaukie, Michigan |publisher=Hal Leonard |date=2003 |isbn=0-634-05548-8 |pages=8–9}}</ref> Around this time, the [[Merry Pranksters]], associated with novelist [[Ken Kesey]], organized the [[Acid Tests]], events in San Francisco involving LSD consumption, accompanied by light shows and improvised music.<ref name=pc41>{{cite web |url=https://digital.library.unt.edu/ark:/67531/metadc19800/m1/ |title=Show 41 – The Acid Test: Psychedelics and a sub-culture emerge in San Francisco.

In San Francisco's Haight-Ashbury neighborhood, the Psychedelic Shop was opened in January 1966 by brothers Ron and Jay Thelin to promote the safe use of LSD. This shop played a significant role in popularizing LSD in the area and establishing [[Haight-Ashbury]] as the epicenter of the hippie counterculture. The Thelins also organized the [[Love Pageant Rally]] in Golden Gate Park in October 1966, protesting against California's ban on LSD.<ref>{{Cite web|title=OBITUARY — Ron Thelin |url=https://www.sfgate.com/news/article/OBITUARY-Ron-Thelin-2989153.php |vauthors=Taylor M |date=1996-03-22 |website=SFGate |access-date=2020-05-13 |url-status=live |archive-date=August 28, 2021 |archive-url=https://web.archive.org/web/20210828153344/https://www.sfgate.com/news/article/OBITUARY-Ron-Thelin-2989153.php}}</ref><ref>{{cite journal |vauthors=Davis JC |title=The business of getting high: head shops, countercultural capitalism, and the marijuana legalization movement. |journal=The Sixties |date=January 2015 |volume=8 |issue=1 |pages=27–49 |doi=10.1080/17541328.2015.1058480 |hdl=11603/7422 |s2cid=142795620 |hdl-access=free}}</ref>

A similar movement developed in London, led by British academic [[Michael Hollingshead]], who first tried LSD in America in 1961. After experiencing LSD and interacting with notable figures such as [[Aldous Huxley]], [[Timothy Leary]], and [[Richard Alpert]], Hollingshead played a key role in the famous LSD research at Millbrook before moving to New York City for his experiments. In 1965, he returned to the UK and founded the World Psychedelic Center in Chelsea, London.<ref>{{cite book | vauthors = Conners P |title=White Hand Society - The Psychedelic Partnership of Timothy Leary and Allen Ginsberg |publisher=City Lights Books |year=2010 |isbn=9780872865358 |page=[https://archive.org/details/isbn_9780872865358/page/148 148] |url-access=registration |url=https://archive.org/details/isbn_9780872865358/page/148 }}</ref>

[[Blotter art]] is an art form printed on perforated sheets of absorbent [[blotting paper]] infused with liquid LSD. The delivery method gained popularity following the banning of the [[hallucinogen]] LSD in the late 1960s. The use of graphics on blotter sheets originated as an [[underground art]] form in the early 1970s, sometimes to help identify the dosage, maker, or batch of LSD.

The influence of LSD in the realms of music and art became pronounced in the 1960s, especially through the Acid Tests and related events involving bands like the [[Grateful Dead]], [[Jefferson Airplane]], and [[Big Brother and the Holding Company]]. San Francisco-based artists such as [[Rick Griffin]], [[Victor Moscoso]], and [[Wes Wilson]] contributed to this movement through their psychedelic poster and album art. [[The Grateful Dead]], in particular, became central to the culture of "Deadheads," with their music heavily influenced by LSD.<ref name=Jarnow/>

In the United Kingdom, Michael Hollingshead, reputed for introducing LSD to various artists and musicians like [[Storm Thorgerson]], [[Donovan]], [[Keith Richards]], and members of [[the Beatles]], played a significant role in the drug's proliferation in the British art and music scene. Despite LSD's illegal status from 1966, it was widely used by groups including [[the Beatles]], [[the Rolling Stones]], and [[the Moody Blues]]. Their experiences influenced works such as the Beatles' ''[[Sgt. Pepper's Lonely Hearts Club Band]]'' and Cream's ''[[Disraeli Gears]]'', featuring psychedelic-themed music and artwork.<ref>{{cite magazine |vauthors=Gilmore M |url=https://www.rollingstone.com/feature/beatles-acid-test-how-lsd-opened-the-door-to-revolver-251417/ |title=Beatles' Acid Test: How LSD Opened the Door to 'Revolver' |magazine=Rolling Stone |date=August 25, 2016 |access-date=December 9, 2021 |archive-date=December 3, 2020 |archive-url=https://web.archive.org/web/20201203211257/https://www.rollingstone.com/feature/beatles-acid-test-how-lsd-opened-the-door-to-revolver-251417/ |url-status=live}}</ref>

Psychedelic music of the 1960s often sought to replicate the LSD experience, incorporating exotic instrumentation, electric guitars with effects pedals, and elaborate studio techniques. Artists and bands utilized instruments like sitars and tablas, and employed studio effects such as backward tapes, panning, and phasing.<ref>{{cite book |vauthors=Rubin R, Melnick JP |title=Immigration and American Popular Culture: an Introduction |location=New York, NY |publisher=New York University Press |date=2007 |isbn=978-0-8147-7552-3 |pages=162–4}}</ref><ref>{{cite book |vauthors=Prown P, Newquist HP, Eiche JF |title=Legends of Rock Guitar: the Essential Reference of Rock's Greatest Guitarists |location=London |publisher=Hal Leonard Corporation, 1997 |isbn=0-7935-4042-9 |pages=48 |year=1997}}</ref> Songs such as [[John Prine]]'s "Illegal Smile" and the Beatles' "[[Lucy in the Sky with Diamonds]]" have been associated with LSD, although the latter's authors denied such claims.<ref name=Sheff>{{cite book |vauthors=Sheff D |year=2000 |author-link=David Sheff |title=All We Are Saying: The Last Major Interview with John Lennon and Yoko Ono |publisher=St. Martin's Press |location=New York |isbn=978-0-312-25464-3 |url=https://archive.org/details/allwearesayingla00lenn |url-access=registration}}</ref>{{page needed|date=January 2024}}<ref name="life">{{cite magazine |vauthors=Thompson T |date=16 June 1967 |title=The New Far-Out Beatles |magazine=Life |url=https://books.google.com/books?id=lVYEAAAAMBAJ&pg=101 |location=Chicago |publisher=Time Inc. |pages=101 |access-date=8 Dec 2016 |archive-date=November 17, 2021 |archive-url=https://web.archive.org/web/20211117042255/https://books.google.com/books?id=lVYEAAAAMBAJ&pg=101 |url-status=live}}</ref>

===Legal status===
The [[United Nations]] [[Convention on Psychotropic Substances]] of 1971 mandates that signing parties, including the United States, Australia, New Zealand, and most of Europe, prohibit LSD. Enforcement of these laws varies by country. The convention allows medical and scientific research with LSD.<ref>{{cite web |work=UN Convention on Psychotropic Substances |date=1971 |url=http://www.unodc.org/pdf/convention_1971_en.pdf |title=Final act of the United Nations Conference |archive-url=https://web.archive.org/web/20120415011336/http://www.unodc.org/pdf/convention_1971_en.pdf |archive-date=15 April 2012}}</ref>

====Australia====
In Australia, LSD is classified as a Schedule 9 prohibited substance under the Poisons Standard (February 2017), indicating it may be abused or misused and its manufacture, possession, sale, or use should be prohibited except for approved research purposes.<ref name="Poisons Standard">{{cite web |url=https://www.legislation.gov.au/Details/F2017L00057 |title=Poisons Standard |date=July 2016 |archive-url=https://web.archive.org/web/20170302025331/https://www.legislation.gov.au/Details/F2017L00057 |archive-date=2 March 2017 |work=Therapeutic Goods Administration |publisher=Australian Government Department of Health}}</ref> In Western Australia, the Misuse of Drugs Act 1981 provides guidelines for possession and trafficking of substances like LSD.<ref>{{cite web |title=Misuse of Drugs Act 1981 |date=18 November 2015 |url=http://www.slp.wa.gov.au/pco/prod/FileStore.nsf/Documents/MRDocument:28280P/$FILE/Misuse%20Of%20Drugs%20Act%201981%20-%20%5B06-e0-00%5D.pdf?OpenElement |publisher=Government of Western Australia |archive-url=https://web.archive.org/web/20151222180141/http://www.slp.wa.gov.au/pco/prod/FileStore.nsf/Documents/MRDocument%3A28280P/%24FILE/Misuse%20Of%20Drugs%20Act%201981%20-%20%5B06-e0-00%5D.pdf?OpenElement |archive-date=22 December 2015}}</ref>

====Canada====
In Canada, LSD is listed under Schedule III of the Controlled Drugs and Substances Act. Unauthorized possession and trafficking of the substance can lead to significant legal penalties.<ref name="cdasa">{{cite web|url=http://laws-lois.justice.gc.ca/eng/acts/C-38.8/page-26.html#h-30 |title=Controlled Drugs and Substances Act |access-date=December 15, 2013 |publisher=Canadian Department of Justice |year=1996 |author=Canadian government |website=Justice Laws |archive-url=https://web.archive.org/web/20131215170432/http://laws-lois.justice.gc.ca/eng/acts/C-38.8/page-26.html |archive-date=December 15, 2013 }}</ref>

====United Kingdom====
In the United Kingdom, LSD is a Class A drug under the Misuse of Drugs Act 1971, making unauthorized possession and trafficking punishable by severe penalties. The Runciman Report and Transform Drug Policy Foundation have made recommendations and proposals regarding the legal regulation of LSD and other psychedelics.<ref>{{cite web |url=http://www.druglibrary.org/schaffer/Library/studies/runciman/pf3.htm |title=Drugs and the law: Report of the inquiry into the Misuse of Drugs Act 1971 |archive-url=https://web.archive.org/web/20160130144204/http://www.druglibrary.org/schaffer/Library/studies/runciman/pf3.htm |archive-date=30 January 2016 |location=London |publisher=Police Foundation |date=2000 |work=[[Runciman Report]]}}</ref><ref>{{cite web |url=http://www.tdpf.org.uk/blueprint%20download.htm |title=After the War on Drugs: Blueprint for Regulation |archive-url=https://web.archive.org/web/20131005145241/http://www.tdpf.org.uk/blueprint%20download.htm |archive-date=5 October 2013 |work=Transform Drug Policy Foundation |date=2009}}</ref>

====United States====
In the United States, LSD is classified as a Schedule I controlled substance under the Controlled Substances Act of 1970, making its manufacture, possession, and distribution illegal without a DEA license. The law considers LSD to have a high potential for abuse, no legitimate medical use, and to be unsafe even under medical supervision. The US Supreme Court case Neal v. United States (1995) clarified the sentencing guidelines related to LSD possession.<ref>{{cite court| litigants=Neal v.

====Mexico====
Mexico decriminalized the possession of small amounts of drugs, including LSD, for personal use in 2009. The law specifies possession limits and establishes that possession is not a crime within designated quantities.<ref>{{cite web |url=http://www.elpensador.com.mx/2009/10/17/Ley-de-Narcomenudeo/ |title=Ley de Narcomenudeo |archive-url=https://web.archive.org/web/20101130224127/http://www.elpensador.com.mx/2009/10/17/Ley-de-Narcomenudeo/ |archive-date=30 November 2010 |language=es |work=El Pensador |date=17 October 2009}}</ref>

===Illicit supply chain===

====Production====
[[File:LSDLabGlassware.jpg|thumb|Glassware seized by the DEA.]]

An active dose of LSD is very minute, allowing a large number of doses to be synthesized from a comparatively small amount of raw material. Twenty-five kilograms of precursor [[ergotamine]] [[tartrate]] can produce 5–6&nbsp;kg of pure crystalline LSD; this corresponds to around 50–60&nbsp;million doses at 100&nbsp;μg. Because the masses involved are so small, concealing and transporting illicit LSD is much easier than smuggling [[cocaine]], [[cannabis (drug)|cannabis]], or other illegal drugs.<ref name="DEA-pub">{{cite web|author=DEA |year=2007 |title=LSD Manufacture – Illegal LSD Production |url=https://fas.org/irp/agency/doj/dea/product/lsd/lsd-5.htm |website=LSD in the United States |publisher=U.S. Department of Justice Drug Enforcement Administration |archive-url=https://web.archive.org/web/20070829023659/https://fas.org/irp/agency/doj/dea/product/lsd/lsd-5.htm|archive-date=August 29, 2007}}</ref>

Manufacturing LSD requires laboratory equipment and experience in the field of [[organic chemistry]]. It takes two to three days to produce 30 to 100 grams of pure compound. It is believed that LSD is not usually produced in large quantities, but rather in a series of small batches. This technique minimizes the loss of precursor chemicals in case a step does not work as expected.<ref name="DEA-pub"/> Ali Altaft, the lead chemist at the [[University of Okara]], in [[Punjab]], [[Pakistan]], performed the synthesis of LSD on video.<ref>{{Cite web | vauthors = Maravelias P |date=2024-12-18 |title=Willy Myco Just Released the First-Ever Video Demonstrating How to Synthesize LSD |url=https://doubleblindmag.com/willy-myco-lsd-synthesis-in-pakistan/ |access-date=2025-02-10 |website=DoubleBlind Mag |language=en-US}}</ref>

=====Forms=====
LSD is produced in crystalline form and is then mixed with [[excipient]]s or redissolved for production in ingestible forms. Liquid solution is either distributed in small vials or, more commonly, sprayed onto or soaked into a distribution medium. Historically, LSD solutions were first sold on sugar cubes, but practical considerations{{clarification needed|date=September 2024}} forced a change to [[Tablet (pharmacy)|tablet]] form. Appearing in 1968 as an orange tablet measuring about 6&nbsp;mm across, "Orange Sunshine" acid was the first largely available form of LSD after its possession was made illegal. [[Tim Scully]], a prominent chemist, made some of these tablets, but said that most "Sunshine" in the USA came by way of Ronald Stark, who imported approximately thirty-five million doses from Europe.<ref name=Stafford1992>{{cite book |vauthors=Stafford P |year=1992 |title=Psychedelics Encyclopaedia |chapter=Chapter 1 – The LSD Family |pages=62 |edition=3rd |publisher=Ronin Publishing |isbn=978-0-914171-51-5}}</ref>

Over some time, tablet dimensions, weight, shape and concentration of LSD evolved from large (4.5–8.1&nbsp;mm diameter), heavyweight (≥150&nbsp;μg), round, high concentration (90–350&nbsp;μg/tab) dosage units to small (2.0–3.5&nbsp;mm diameter) lightweight (as low as 4.7&nbsp;μg/tab), variously shaped, lower concentration (12–85&nbsp;μg/tab, average range 30–40&nbsp;μg/tab) dosage units. LSD tablet shapes have included cylinders, cones, stars, spacecraft, and heart shapes. The smallest tablets became known as "Microdots."<ref name=Laing2003>{{cite book |vauthors=Laing RR, Beyerstein BL, Siegel JA |year=2003 |title=Hallucinogens: A Forensic Drug Handbook |chapter=Chapter 2.2 – Forms of the Drug |chapter-url=https://books.google.com/books?id=l1DrqgobbcwC |pages=39–41 |publisher=Academic Press |isbn=978-0-12-433951-4 |access-date=May 12, 2020 |archive-date=February 2, 2021 |archive-url=https://web.archive.org/web/20210202134552/https://books.google.com/books?id=l1DrqgobbcwC |url-status=live}}</ref>

======Blotters======
[[Blotter art]] designs printed on blotter paper can serve to identify dosage strengths, different batches, or makers.<ref name="Sfetcu">{{cite book |last1=Sfetcu |first1=Nicolae |title=Health & Drugs: Disease, Prescription & Medication |date=2014 |publisher=Nicolae Sfetcu |page=1958 |url=https://books.google.com/books?id=8jF-AwAAQBAJ&dq=acid+blotter+art&pg=PA1958 |language=en |access-date=2023-07-14 |archive-date=2023-07-14 |archive-url=https://web.archive.org/web/20230714011256/https://books.google.com.ar/books?id=8jF-AwAAQBAJ&newbks=1&newbks_redir=0&lpg=PA1958&dq=acid%20blotter%20art&pg=PA1958#v=onepage&q=acid%20blotter%20art&f=false |url-status=live }}</ref>

On the other hand, blotters without art may be considered safer by some, since there is no guarantee that the [[ink cartridge|printer ink]] used in clandestine production is edible or non-toxic for long-term exposure, and it is also possible for unscrupulous dealers to mimic reputable blotter art designs in order to boost sales.

LSD manufacturers and traffickers in the United States can be categorized into two groups: A few large-scale producers, and an equally limited number of small, clandestine chemists, consisting of independent producers who, operating on a comparatively limited scale, can be found throughout the country.<ref>{{cite book |vauthors=MacLean JR, Macdonald DC, Ogden F, Wilby E |chapter=LSD-25 and mescaline as therapeutic adjuvants. |veditors=Abramson H |title=The Use of LSD in Psychotherapy and Alcoholism |publisher=Bobbs-Merrill |location=New York |date=1967 |pages=407–426}}</ref><ref>{{cite book |vauthors=Ditman KS, Bailey JJ |chapter=Evaluating LSD as a psychotherapeutic agent |veditors=Hoffer A |title=A program for the treatment of alcoholism: LSD, malvaria, and nicotinic acid |pages=353–402}}</ref>

As a group, independent producers are of less concern to the [[Drug Enforcement Administration]] than the large-scale groups because their product reaches only local markets.<ref name="LSD: The Drug"/>

Many LSD dealers and chemists describe a religious or humanitarian purpose that motivates their illicit activity. Nicholas Schou's book ''Orange Sunshine: The Brotherhood of Eternal Love and Its Quest to Spread Peace, Love, and Acid to the World'' describes one such group, [[the Brotherhood of Eternal Love]]. The group was a major American LSD trafficking group in the late 1960s and early 1970s.<ref>{{cite book| vauthors=Schou N |title=Orange Sunshine: The Brotherhood of Eternal Love and Its Quest to Spread Peace, Love, and Acid to the World |date=2010 |publisher=Thomas Dunne Books |url=https://archive.org/details/orangesunshinebr00scho_0 |url-access=registration |isbn=9780312551834}}</ref>

In the second half of the 20th century, dealers and chemists loosely associated with the [[Grateful Dead]] like [[Owsley Stanley]], [[Nicholas Sand]], Karen Horning, Sarah Maltzer, "Dealer McDope," and [[Leonard Pickard]] played an essential role in distributing LSD.<ref name=Jarnow>{{cite book| vauthors=Jarnow J |title=Heads: A Biography of Psychedelic America |date=2016 |publisher=Da Capo Press |isbn=9780306822551}}</ref>
