Microdosing refers to taking a small dose of a psychedelics (such as magic mushrooms), well below the threshold of the evident effects usually associated with the drug, while going about ones daily activities. At this level there are no psychedelic effects, or even immediately obvious effects, it becomes more stimulatory and nootropic in nature. You might not feel any particular drug effects at sub-threshold doses, but at the end of the day you might notice that it was a particularly good day, and you got the things done that needed to be done. There is a lot of debate on how much you should “feel” a microdose, and at the end of the day, your dosage and regime is up to you. It is advisable to keep your dosage and frequency to the minimum effective dose, as too heavy or too frequent dosing can lead to fatigue in the serotonin network and increase the incidence of unwanted side effects.
