Overview

What to know

CBN (cannabinol) forms as THC breaks down with age, heat and light. It is mildly psychoactive at most and is widely marketed in sleep products, often paired with CBD or melatonin. Because aged plant material yields little of it, much commercial CBN is produced by converting other hemp cannabinoids.

CBN has been sold as a hemp product under the 2018 Farm Bill. It is not FDA-approved for any use, and the FDA's general position against cannabinoids in food and supplements applies.

The federal hemp redefinition raises open questions for CBN starting December 11, 2026. Products must stay under 0.4 mg total THC per container, and cannabinoids synthesized or manufactured outside the plant are excluded from hemp, which could reach CBN made by conversion. The law directed the FDA to publish lists of naturally occurring and THC-class cannabinoids, and those lists would help settle how CBN is treated. Check your state's rules, as some states regulate CBN directly.

FAQ

Common questions

Is CBN legal federally?

Hemp-derived CBN is not a controlled substance today. Starting December 11, 2026, CBN products must contain no more than 0.4 mg total THC per container, and CBN made outside the plant could fall under the new exclusion for synthesized cannabinoids.

Is CBN the same as THC?

No. CBN is a breakdown product of THC and is far less intoxicating. It is a different compound with a different legal treatment.

Will CBN be banned in December 2026?

The law does not name CBN. How it is treated will depend on how it is made and on the FDA cannabinoid lists the law requires, which have not been published.
