    Summary PsychonautWiki

    Hexahydrocannabinol (HHC) is a cannabinoid analogue that has been marketed as an "alternative cannabinoid" since 2021. It is a saturated cannabinoid, meaning it has no double bonds in its chemical structure, which differentiates it from other cannabinoids such as THC. The mechanism of action is binding activity at cannabinoid receptors distributed throughout the body.

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

    Tip: for quicker logging you can also add a Custom Unit in the app, e.g. common dose ~ 21 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.
