CBNA
Aliases: Cbna-c5, Cannabinol acid
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.

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.
