Ok so psilocybin is the active chemical in “shrooms”. Your body almost instantly builds a tolerance to it making it near impossible to get addicted too. You would have to constantly take really high doses to do so. They just now legalized it for medical use, although it will be 2 years before it goes into effect. Micro dosing it will give you a slight uplifting feeling without the psychedelic effects it would have at higher doses. Because of this it can be used to cure depression, anxiety and, PTSD. In this case it would be administered in a gel capsule.
