Summary
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
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.)
| ROA | Light | Common | Strong | Heavy |
|---|---|---|---|---|
| Oral | 10-25mg | 25-50mg | 50-100mg | 100mg+ |
| Sublingual | 5-15mg | 15-30mg | 30-60mg | 60mg+ |
Onset, Duration & After-effects
| ROA | Onset | Peak | Offset | Total |
|---|---|---|---|---|
| Oral | 30-90 min | 1.5-3 hrs | 1-2 hrs | 3-6.5 hrs |
| Sublingual | 10-30 min | 1.5-3 hrs | 1-2 hrs | 2.67-5.5 hrs |
Add to PsychonautWiki Journal
The PsychonautWiki Journal logging app doesn't include every substance. To track CBNA there, start adding an ingestion, search for the name, and choose to add it as a custom substance. Paste these values:
CBNA Source: SubstanceSearch (substancesearch.com) Oral dose (mg): threshold 5 · light 10-25 · common 25-50 · strong 50-100 · heavy 100+ Sublingual dose (mg): threshold 2 · light 5-15 · common 15-30 · strong 30-60 · heavy 60+ Oral duration: onset 0.5-1.5h · peak 1.5-3h · offset 1-2h · total 3-6.5h · after-effects 12h Sublingual duration: onset 10-30m · peak 1.5-3h · offset 1-2h · total 2.67-5.5h · after-effects 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 ~ 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.
Tolerance
Tolerance Decay
Acute tolerance: develops within a single session — the reset numbers above apply after sustained heavy use, not after one binge. Within-session tachyphylaxis usually resets largely overnight.
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.
