The Cost of Exclusion in Psychedelic Research

In the last two decades, researchers have started to reexamine psychedelics for their therapeutic potential. Though initial results seem promising, the research has a significant shortcoming: the lack of racial and ethnic diversity among research teams and study participants. In the 1960s, psychedelic substances such as LSD, psilocybin, and mescaline were a major part of American counterculture. Less well-known is that, concurrently, researchers were studying potential therapeutic uses of these mind-altering substances. Unfortunately, psychedelics were classified as Schedule I drugs in 1970, halting research into their therapeutic benefits. The recent renaissance of psychedelic research shows these substances have significant capabilities for treating anxiety, depression, posttraumatic stress disorder (PTSD), and substance use disorders. But these promising results are limited in their applicability: an analysis from 2018 showed that 82.3% of all study participants in psychedelic trials internationally were non-Hispanic Whites, and only 2.5% were African-American.
