Microdosing psilocybin means taking a tiny dose of the substance every day or several times a week, as you may with a dietary supplement, for example. The idea is that you can experience and maintain the benefits of psilocybin without going as far as embarking on a full-scale psychedelic journey. People who microdose are generally looking to improve their mood, relieve chronic pain, improve cognitive function, or reduce symptoms of depression. Microdosing is a particularly fashionable technique thought up by psychologist James Fadiman, who recommends taking microdoses every other day. As an example, a “microdose” is typically around 0.3 g of truffle.
