Since CBN is considered a minor cannabinoid in the hemp plant, it is found in low concentrations. This means that it is much more challenging to isolate CBN for use and research due to its difficulty in producing a large amount and the time it takes to make it. CBN will be much more expensive than CBD, for example. CBN will be up to 10 times the price of CBD per mg. You won’t find many CBN products on the market, and supply and demand play a significant role in their price.
