The Science of Microdosing Psychedelics – A Short Review

In 2011, Jim Fadiman PhD described the intake of very low doses of psychedelics (e.g. 10–20 mcg of LSD). Claims about “microdosing” include better work performance, less procrastination, better mood, more creativity, psychological well-being and healthier life habits.

This lecture provides a rough overview on the history of microdosing and describes existing research on the effects of low doses of LSD, psilocybin and mescaline. Including; the place of microdosing and minidosing in the context of pharmacology, effects of psychedelics on the human psyche and organism, possible effects on performance, creativity, headaches, anxiety and depression, side effects and mechanisms of action, and concluding with thoughts on microdosing as a socio-psychological phenomenon assimilating psychedelics in our culture.
