We microdose for seasonal depression (North Scotland), it's illegal, so we don't broadcast it. There's more info on reset.me. In UK, The Beckley Foundation, & Davis Nutt, are the forerunners, Open Foundation in the Netherlands & John Hopkins University & MAPS, are in USA. Please be careful, & make sure you either enter into a clinical drug trial, in a safe environment, or you REALLY know your shit. Erowid.org is a good tool for researching illegal drugs, check out the experiences BEFORE trying anything new.
