CBN (cannabinol) in plain English

A mildly intoxicating cannabinoid formed as THC degrades with time, light and heat.

Because it is a breakdown product, higher CBN content generally indicates older material rather than a deliberately produced feature.

CBN is widely marketed in connection with sleep. That association rests mainly on preclinical work and on the fact that degraded cannabis was historically described as more sedating; controlled human evidence in insomnia is very limited.
