Add to PsychonautWiki Journal
The PsychonautWiki Journal logging app doesn't include every substance. To track Barbital there, start adding an ingestion, search for the name, and choose to add it as a custom substance. Paste these values:
Barbital Source: SubstanceSearch (substancesearch.com) Oral dose (mg): common 650-970 Oral duration: onset 15-30m · peak 6-12h · total 6-12h Note: ranges are harm-reduction guidance, not a prescription. Start low, go slow, and test your substances.
Tip: for quicker logging you can also add a Custom Unit in the app, e.g. common dose ~ 810 mg (Oral).
The app keeps custom substances simple, so the full dose ranges live in the description text above. Ranges are harm-reduction guidance, not a prescription.
