Micro-dosing is the practice of consuming very low, sub-hallucinogenic doses of a psychedelic substance. The goal of micro-dosing magic mushrooms is to attain the positive effects of psilocybin, the active ingredient in magic mushrooms, without the heavier effects such as hallucination, sensory shifts or other experiential effects that a full dose can have. Micro-doses are supposed to have sub-perceptual effects, so if you are “really feeling it,” your dose may not be “micro” enough. Starting small is the key! Magic mushrooms can take up to an hour to take effect.
