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.
