CBN (Cannabinol)

Cannabinol (CBN) is a cannabinoid found in the Cannabis sativa plant, so it is part of the phytocannabinoids family, just like cannabidiol (CBD) and tetrahydrocannabinol (THC).

As its name suggests, CBN is related to THC, the compound being in fact a metabolite of tetrahydrocannabinol. This means that cannabinol is obtained from THC, through a process that involves both natural and special treatments.

Unlike other cannabinoids, CBN does not stem directly from cannabigerol (CBG) or cannabigerolic acid (CBGA), but rather is the degraded product of tetrahydrocannabinolic acid (THCA).If cannabis is exposed to air or ultraviolet light (for example, in sunlight) for a prolonged period of time, THCA will convert to cannabinolic acid (CBNA). CBN is then formed by decarboxylation of CBNA.


The third best-known cannabinoid after CBD and THC, CBN is non-psychoactive. It may also be responsible for the sedative effects of some cannabis plants.

Cannabinol is soluble in fats and dissolves well in ethanol and methanol. If the cannabis plant is cut and stored at room temperature, in no special conditions, the exposure to air causes the degradation of THC to CBN, no enzymes being required for this process. Thus, if a plant has a higher concentration of CBN, it generally means that it has been stored in poor conditions and not in airtight containers.

What studies say about cannabinol (CBN)

Thanks to its sedative effects, CBN may relieve temporary symptoms of sleeplessness. 

A research from 2008 suggests that cannabinol, when applied topically, could be nourishing to the skin. Also,another research has shown that CBN can stimulate the appetite and the analgesic capabilities in the body.
Other research shows CBN has the ability to fight harmful bacteria. A 2008 study found CBN one of several cannabinoids (including CBD) effective in treating MRSA, and bacterial infection that is resistant to antibiotics.
Cannabinol (CBN) has also been shown to reduce  (IOP) intraocular pressure and neuroprotective action

CBN's property to reduce the pressure inside the eye is also found in THC, which is more psychoactive, so research is still needed to find the best solution while minimizing side effects and avoiding the euphoric feelings induced by the two phytocannabinoids.
