Harm reduction tool to track your drug, reaserach chemical, nootropic, and substance use.




About

ChemLog is an app that can help you record your drug, research chemical, nootropic use, as well as provide curated information on substances; all for the purpose of harm-reduction. ChemLog's design is inspired by KnowDrugs and ChemDiary, but open source, well-maintained, highly polished, privacy-first, and always free.

We source much of our substance data from TripSit Factsheets and PsychonautWiki.
