CBN is a chemical compound found in cannabis plants, just like THC and CBD. It is believed to have mild sedative effects and is known to be non-psychoactive. While both marijuana and CBN have similar effects, the THC metabolite that is detected in drug tests is significantly more potent in marijuana than in CBN. Therefore, CBN is a less detectable form of THC, which makes it a preferable choice for those wanting to avoid a positive drug test.
