    The PsychonautWiki Journal logging app doesn't include every substance. To track NEB there, start adding an ingestion, search for the name, and choose to add it as a custom substance. Paste these values:

Oral dose (mg): threshold 30 · light 30-50 · common 50-80 · strong 80-100 · heavy 100+

Insufflated duration: onset 5-10m · peak 1.5-2h · after-effects 1-6h
Oral duration: onset 20-30m · peak 1.5-3h · after-effects 1-6h

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 ~ 22.5 mg (Insufflated).

    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.
