“Microdosing psychedelics is the practice of taking 1/10th to 1/20th of a full ‘journey’ dose of mushrooms, LSD, San Pedro, or another entheogenic substance. The phrase was coined in 2011 by longtime psychedelic researcher James Fadiman, PhD, in his book, ‘The Psychedelic Explorer’s Guide’, and has since become a cultural phenomenon.”

Who shouldn't microdose?
“We specifically do not recommend that people with colorblindness, who live with diagnoses of psychotic disorders or along the autism spectrum try microdosing. People with colorblindness report lasting visual distortions from microdosing. Literature suggests people with psychotic disorders may be harmed by psychedelics. In our experience, people with diagnoses along the autism spectrum seem to require dosages that far exceed what is traditionally considered microdosing.”
