Add to PsychonautWiki Journal
The PsychonautWiki Journal logging app doesn't include every substance. To track Hexobarbital there, start adding an ingestion, search for the name, and choose to add it as a custom substance. Paste these values:
Hexobarbital Source: SubstanceSearch (substancesearch.com) Oral dose (mg): light 10-15 · common 15-20 · strong 20-30 · heavy 30+ Oral duration: onset 1-2m · peak 30-45m · total 30-45m · after-effects 1-4h 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 ~ 17.5 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.
