Cannabinol, a mildly psychoactive cannabinoid formed when THC degrades, often associated with sedative properties.
Cannabinol, or CBN, is a mildly psychoactive cannabinoid that forms when THC degrades over time through exposure to heat, light, and oxygen. It is not produced directly by the cannabis plant but rather appears as aged cannabis breaks down, which is why older flower tends to contain higher CBN levels.
Effects and Research
CBN has gained attention for its potential sedative properties, leading many product manufacturers to market it as a sleep aid. However, scientific evidence for this claim is limited. A 1975 study suggested that CBN combined with THC enhanced drowsiness, but CBN alone showed minimal sedative effect in subsequent research. CBN does interact with CB1 and CB2 receptors, albeit with lower affinity than THC, and early studies suggest it may have anti-inflammatory, antibacterial, and appetite-stimulating properties.
Practical Uses
CBN is increasingly available in sleep-focused cannabis products including tinctures, capsules, and gummies, often combined with CBD, melatonin, or other calming ingredients. If you find that older cannabis makes you sleepier than fresh flower, the elevated CBN content may be a contributing factor. For consumers interested in trying CBN, look for lab-tested products that clearly state the CBN content per serving rather than relying on anecdotal marketing claims.
