[Solved] What is the history of LSD therapy?

LSD (lysergic acid diethylamide) was discovered by the Swiss chemist Albert Hofmann in 1938. Hofmann worked for the pharmaceutical company Sandoz in Basel, Switzerland, and investigated substances derived from ergot (a fungus that grows on rye) for potential medicinal applications.

Discovery and early experiences (1938–1943)

• 1938: Hofmann first synthesised LSD, but little attention was paid to it at the time because, initially, no practical use for it was apparent.
• 16 April 1943: Hofmann decided to investigate LSD again and accidentally came into contact with a small dose. He experienced strange sensory changes and an altered state of consciousness.
• 19 April 1943 (later known as "Bicycle Day"): Hofmann deliberately took a dose of 250 micrograms of LSD. This experience confirmed the powerful psychoactive effects of LSD, including changes in perception, emotion and self-awareness.

Early research (1940–1960)

From the 1940s through to the 1960s, LSD was extensively researched as a potential therapeutic agent, mainly in Europe and the United States. These early studies showed that LSD had great potential for treating psychiatric disorders, such as:

• Alcoholism and addiction: Studies have shown promising results, with a large number of patients reporting that LSD therapy helped them to gain insight into their addiction and brought about lasting behavioural change.
• Anxiety and depression: Patients often experienced relief from their symptoms and a lasting sense of improved mood and well-being.
• Psychotherapy: LSD was used as a catalyst for deeper psychoanalytic and psychotherapeutic processes, as it made it easier for patients to access repressed memories and emotions.

Popularity and Controversy (1960–1970)

In the 1960s, LSD became popular outside the medical world and began to be used as a recreational drug, particularly by the hippie movement. This led to public concern, making research and therapy increasingly controversial.

Due to growing concern and political pressure, LSD was eventually banned:

At 1966 LSD was banned in the US and in 1971 LSD was banned internationally and added to the UN list of prohibited substances.

The revival of psychedelic therapy (2000–present)

Since around the year 2000, there has been a renewed interest in LSD and other psychedelics as therapeutic agents. Recent studies are once again showing promising results for conditions such as:

• Anxiety in terminally ill patients
• Post-traumatic stress disorder (PTSD)
• Severe depression and addiction

These modern studies often confirm the initial findings from the 1950s and 1960s, and LSD is now once again being taken seriously in scientific and medical circles.

Summary of the initial findings:

The first studies into LSD showed that it was capable of eliciting profound psychological insights and, in some patients, led to long-lasting behavioural changes. Despite promising results, LSD was kept out of medical practice for a long time for social and political reasons, but psychedelic therapy is now undergoing a resurgence, underpinned by fresh, positive and scientifically substantiated research.
