CBN is a phytocannabinoid product of the oxidation degradation of THC. It is produced by the conditions of exposure to ultraviolet radiation and high temperatures (during the last stages of the flowering cycle). Conditions resulting from prolonged storage of harvested plant material also cause such degradation by oxidation from THC to CBN. It is also produced by decarboxylation of its acid form (CBNA).

CBN has less psychotropic intensity than THC (about 25%) and its effects are different. In terms of recreational use, the effects of CBN are associated with states of relaxation or sedation. Remember always that any psychotropic substance acts differently in each person.
