Phytocannabinoid
CBN (Cannabinol)
CBN, or cannabinol, is a mildly psychoactive cannabinoid produced as THC degrades through oxidation. Aged cannabis flower contains progressively more CBN. CBN is marketed for sleep, though the clinical evidence base is modest. It binds weakly to both CB1 and CB2 receptors.
Associated effects
mildly sedating, sleep-marketed
CBN is essentially the breakdown product of THC. When cannabis flower is exposed to oxygen, heat, and light over time, THC slowly oxidizes into CBN. This is why aged or improperly stored cannabis tests lower in THC and higher in CBN. The compound has weak affinity at CB1 and CB2 receptors and only mild psychoactivity. CBN has been heavily marketed as a sleep aid, though the clinical evidence supporting that use case remains modest — many of the sleep effects often attributed to CBN are more reliably attributable to terpenes like myrcene and linalool.
