Despite tens of thousands of years of use by humans around the world, psychedelics were abruptly made illegal to supply and possess by a UN convention in 1971 as a consequence of President Nixon’s War on Drugs.
Whilst the policy was framed as promoting public health, one of Nixon’s top advisors said in 1994 that the drug war was in fact a ploy to undermine Nixon's political opposition :
"You want to know what this was really all about? The Nixon campaign in 1968, and the Nixon White House after that, had two enemies: the antiwar left and black people. You understand what I'm saying? We knew we couldn't make it illegal to be either against the war or black, but by getting the public to associate the hippies with marijuana and blacks with heroin, and then criminalizing both heavily, we could disrupt those communities. We could arrest their leaders, raid their homes, break up their meetings, and vilify them night after night on the evening news. Did we know we were lying about the drugs? Of course we did."
To this day, the UK government persists in claiming that psychoactive substances are classified on the basis of harm, but the House of Commons’ own Science and Technology Committee has described UK drug law as "arbitrary", "unscientific" and "based on historical assumptions, not scientific assessment", and the government's chief drug adviser was famously sacked when he pointed out that classical psychedelics are far less dangerous than alcohol.
Let's examine some key arguments for why psychedelics should be legal to supply and possess.
The benefit argument
Studies suggest psychedelics could be a breakthrough therapy for mental health issues including depression, anxiety, addiction, OCD, and PTSD through their ability to work on a deep emotional as well as biological level. Matthew Johnson, who leads the Johns Hopkins University Psilocybin Research Project, says "Unlike almost all other psychiatric medications that have a direct biological effect, these drugs seem to work through biology to open up a psychological opportunity”.
Psychedelics can also bring about profoundly positive and meaningful experiences for people who aren't facing any particular issue or difficulty. In a study by the Johns Hopkins School of Medicine, 80% of those who received psilocybin said it was one of the five most meaningful experiences of their lives; 50% said it was the single most meaningful experience. Many of the participants said they were left with the sense that they understood themselves and others better and therefore had greater compassion and patience - a change reported by their colleagues, friends and families too.
Psychedelics may also improve creativity and problem-solving abilities. Apple's Steve Jobs said taking LSD was "one of the most important things [I did] in my life" , whilst Gregory Sams, co-founder of Whole Earth Foods, said "It was as a direct consequence of my brother and myself taking LSD that we introduced natural and organic foods in the UK."
The liberty argument
A 2010 study rated LSD and magic mushrooms as among the safest of 19 commonly used drugs, significantly safer than alcohol and tobacco.
Surely any psychoactive substance less risky than alcohol should be legally available in some way? Anything else is pure discrimination against sections of the population that happen to prefer other substances.
What possible justification is there for saying "OK, you can legally go out binge drinking every Friday and Saturday night, but if you go out picking for magic mushrooms once a year then we'll lock you up"?
The substitution argument
The use of psychoactive substances is a near universal practice of human cultures across history. Whatever the laws, people will still use psychoactive substances.
Were psychedelics and other low risk substances legalised, we would likely see a net health benefit to society as (at least some of the time) people chose to consume psychedelics instead of alcohol and other riskier substances. Prof David Nutt estimates that a regulated market in cannabis could cut alcohol consumption by up to 25%.
