    Summary dose.wiki

    CBNA (cannabinolic acid) is the carboxylated precursor of cannabinol (CBN), formed when THCA oxidizes. It is produced naturally during storage and aging of cannabis, or rapidly when heated above ~110°C. CBNA itself has minimal affinity for CB1/CB2 receptors and is regarded as non-intoxicating.

    Dose Information Drugs.Wiki

    Dose basis. No established clinical dosing. Numbers are extrapolated from vendor guidance and scattered user reports; potency varies with product stability and decarboxylation state. Lipid vehicles likely increase absorption. Anecdotal reports only; absorption and onset depend on formulation and contact time. Heating to aid dissolution risks decarboxylation to CBN. (Dose figures and this note are from Drugs.Wiki.)

    Tolerance

    Build-up develops over weeks of regular use via CB1 receptor downregulation
    Reset 2–4 weeks for most users; heavy users may need longer

    Tolerance Decay

    Full tolerance 21d Half tolerance 14d Baseline ~28d

    Cannabinoid‑like sedation shows some tolerance with frequent daily use, likely driven by any co‑present/formed CBN rather than CBNA itself. Data quality is low and based on inference from related cannabinoids and user reports; expect individual variability.

    Tip: for quicker logging you can also add a Custom Unit in the app, e.g. common dose ~ 37.5 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.
