A new report published in Drug Science, Policy and Law suggests that psychedelic drugs may improve symptoms of color blindness. The study discusses 23 anecdotal reports describing improved color blindness after taking drugs like lysergic acid diethylamide (LSD) and psilocybin (also known as “magic mushrooms”).
Anecdotal and historical reports have long contended that psychedelic drugs can alter color vision. Researchers JEC Anthony and colleagues say that barriers to conducting research on these drugs have slowed down the study of this topic.
In a previous research project, Anthony and colleagues received reports from participants who described changes in their color blindness symptoms following the use of psychedelics. Motivated to explore whether experiences like these are common, the researchers analyzed responses to a large-scale annual drug survey — the 2017 edition of the Global Drugs Survey (GDS).
