Hallucinogens and Psychedelics

150
Hallucinogens are psychoactive substances that profoundly alter perceptual experiences, generating unreal visual and sensory images. Often referred to as psychedelic drugs — a term derived from the Greek words "psyche" (mind) and "delos" (revealing) — these substances include marijuana and lysergic acid diethylamide (LSD), among others. These drugs vary in intensity and effects.
Marijuana, derived from the dried leaves and flowers of the hemp plant, contains...

CNS Stimulants: Psychedelic Agents

114
Hallucinogens, also known as psychedelic drugs, are a class of substances known for their ability to alter perception, cognition, and emotions. Despite their profound effects on the mind, these drugs are non-addictive, setting them apart from many other abused substances. The mechanism of action of these drugs lies in their impact on the 5-HT2A receptor in the brain. Upon activation, this receptor couples to Gq-type G proteins, triggering a cascade that releases intracellular calcium. This...

Altered States of Awareness01:06

Altered States of Awareness

145
Altered states of consciousness represent significant deviations from one's normal mental state. These deviations can range from subtle changes in awareness to profound transformations in perception, thought processes, and sensory experiences. Altered states of consciousness can be triggered by various factors, including drug use, meditation, hypnosis, illness, or even intense fatigue.
The ingestion of substances like stimulants or hallucinogens leads to chemical alterations in the brain...

Summary

Lifetime use of classic psychedelics was linked to a 25% reduction in frequent severe headaches. This finding suggests psychedelics may offer a novel prophylactic treatment for primary headache disorders like migraine.

Area of Science:

  • Neuroscience
  • Psychopharmacology
  • Epidemiology

Background:

  • Migraine and cluster headaches are primary headache disorders with limited conventional treatment options.
  • Classic psychedelic substances, including lysergic acid diethylamide (LSD) and psilocybin, show potential as novel therapeutic agents for these conditions.

Purpose of the Study:

  • To examine the association between lifetime classic psychedelic use and the prevalence of frequent severe headaches.
  • To investigate the potential of psychedelics in managing primary headache disorders within a large British cohort.

Main Methods:

  • Cross-sectional analysis of data from 11,419 participants in the 1958 British National Child Development Study (collected 1999-2000).
  • Multiple logistic regression models were employed, controlling for potential confounding factors.
  • The study tested the hypothesis that classic psychedelic use is associated with reduced odds of experiencing frequent severe headaches.

Main Results:

  • Lifetime use of classic psychedelics was significantly associated with a 25% decrease in the odds of reporting frequent severe headaches (adjusted odds ratio = 0.75, 95% CI: 0.59-0.95, p = 0.016).

Conclusions:

  • The findings support the growing body of evidence suggesting classic psychedelics as a potential prophylactic treatment for primary headache disorders.
  • Further research into psychedelic-assisted therapies for conditions like migraine and cluster headaches is warranted.
