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. Limited animal research suggests mild anti-inflammatory and analgesic activity; anecdotal human use points to gentle sedation similar to low-dose CBN. Pharmacokinetic and toxicological data are sparse due to scarcity on the recreational market.
