Cannabinol

The oxidized (aged) form of THC. CBN is a weaker version of THC. When Δ9-THC oxidizes, which happens as cannabis ages, it degrades into CBN. CBN has about 25% the intoxicating ability as Δ9-THC. Many have attributed sedative effects to CBN, but these claims are not substantiated by scientific literature.
