About Us

About MAPS

Founded in 1986, MAPS is a 501(c)(3) non-profit research and educational organization that develops medical, legal, and cultural contexts for people to benefit from the careful uses of psychedelics and marijuana. MAPS is sponsoring the most advanced psychedelic therapy research in the world: Phase 3 clinical trials of MDMA-assisted therapy for PTSD. Since MAPS was founded, philanthropic donors and grantors have given more than $130 million for psychedelic and marijuana research and education. MAPS has earned both the Guidestar Platinum Seal of Transparency and a 4-Star Rating from Charity Navigator.


MAPS Public Benefit Corporation (MAPS PBC) catalyzes healing and well-being through psychedelic drug development, therapist training programs, and sales of prescription psychedelics while prioritizing public benefit above profit. Founded in 2014, MAPS PBC is a wholly-owned subsidiary of the Multidisciplinary Association for Psychedelic Studies (MAPS), a 501(c)(3) non-profit organization. It is the parent company of MAPS EU, formed to organize and administer clinical trials of MDMA-assisted therapy for PTSD in the United Kingdom and European Union.

About Psychedelics


MDMA was invented in 1912 by chemist Anton Köllisch of Merck but was largely unexplored for medical or psychiatric use until 1976, when Alexander Shulgin and Leo Zeff identified its potential in therapy. Due to its popularity in social contexts, in 1983 MDMA was caught up in the War on Drugs and swiftly prohibited, halting all research into its potential as an adjunct, or catalyst, to therapy. In 2001, Rick Doblin, Ph.D., outlined MAPS’ strategy for the development of MDMA-assisted therapy for PTSD and in 2004, the first study participant was treated by Dr. Michael Mithoefer and Annie Mithoefer in Charleston, South Carolina. 

Today, MAPS is sponsoring the second of two Phase 3 trials for FDA evaluation of MDMA-assisted therapy for PTSD, anticipated to conclude with approval in 2023.  MDMA-assisted therapy may hold potential in the treatment of eating disorders, anxiety associated with advanced-stage illness, and social anxiety. Research into treatment for couples in which one partner has been diagnosed with PTSD combines MDMA-assisted therapy with conjoint cognitive behavioral therapy. 

MDMA is not the same as “Ecstasy” or “molly.” Substances sold in unregulated markets under these names may contain MDMA, but frequently also contain unknown and/or dangerous adulterants. In laboratory studies, pure MDMA has been proven sufficiently safe for human consumption when taken a limited number of times in moderate doses.

Marijuana Facts

  • Generic name: Cannabis Sativa
  • Chemical name: 6,6,9-trimethyl-3-pentylbenzo[c]chromen-1-ol
  • Compound type: Plant
  • Earliest use: ~2700 BC
  • Prohibited: 1970
  • Conditions under investigation: Chronic pain, PTSD, insomnia, epilepsy
  • Mechanism of action: Activates CB1 (alters mood and cognition) and CB2 receptors (regulate immune responses and anti-inflammatory effects)
  • Expected reactions in therapeutic setting: Increased heart rate, impaired short-term memory, impaired movement, euphoria, relaxation, and altered states of mind.

LSD, or Lysergic Acid Diethylamide, was first synthesized in 1938 in Basel, Switzerland by chemist, Albert Hofmann. Originally one of many lysergamides synthesized with the intent of developing new respiratory stimulants, its psychoactive properties were not discovered until 1943, when it was accidently absorbed through the skin. Hofmann described the effects as an “intoxicated-like condition, characterized by an extremely stimulated imagination” with visual distortions of “extraordinary shapes” and “kaleidoscope play of colors”. Three days later on April 19th, 1943, Hofmann intentionally ingested 250 micrograms of LSD and soon recognized its potential therapeutic benefits.

LSD was introduced as a psychiatric drug in 1947 and used throughout the 1950’s and 1960’s to enhance psychotherapy for the treatments of anxiety, depression, alcoholism, and other diseases. However, psychedelic therapy and research were halted after LSD was classified as a Schedule I substance in 1968, citing no therapeutic potential and the potential for abuse, although this has been disproven. In the US, FDA-approved research in patients and healthy volunteers concluded in the 1980’s.

MAPS has conducted the first double-blind, placebo-controlled study of the therapeutic use of LSD in human beings since the early 1970s. This study took place in Solothurn, Switzerland and investigated the safety and effectiveness of LSD-assisted psychotherapy in subjects with life-threatening illnesses and who are experiencing associated anxiety. The results were that patients experienced significant reductions in anxiety, with no acute or chronic adverse effects beyond one day after treatment.

Due to its drug scheduling, research on LSD continues to be very limited, but demonstrates significant therapeutic potential. Learn more about our progress on our LSD research page.
