You've heard of CBD and THC. But there's another cannabinoid gaining serious attention: CBN (cannabinol). Often called the "sleepy cannabinoid," CBN is being marketed as a natural sleep aid. But does the science support the hype?
What is CBN?
CBN is a cannabinoid that forms when THC ages and oxidizes. It's found in older cannabis and occurs naturally as THC breaks down over time when exposed to heat, light, and oxygen.
Unlike CBD, which is produced directly by the cannabis plant, CBN is a degradation product. This means:
- Fresh cannabis has very little CBN
- Aged or improperly stored cannabis has more CBN
- Commercial CBN is often converted from other cannabinoids
CBN vs CBD: What's the Difference?
| Property | CBN | CBD |
|---|---|---|
| Origin | THC degradation | Direct plant production |
| Psychoactive? | Mildly (much less than THC) | No |
| Primary Use | Sleep | Anxiety, pain, general wellness |
| Research Level | Limited | More extensive |
| Availability | Less common | Widely available |
Does CBN Actually Help Sleep?
Here's the truth: the scientific evidence for CBN as a sleep aid is limited.
The "sleepy cannabinoid" reputation comes largely from anecdotal reports and the observation that older cannabis (which contains more CBN) seems more sedating. However:
- Very few human studies have specifically tested CBN for sleep
- The sedative effect may come from CBN combined with other cannabinoids, not CBN alone
- Some research suggests the sedation is from terpenes in aged cannabis, not CBN itself
The Research Gap
Most CBN sleep claims are based on a single 1975 study that found CBN enhanced THC's sedative effects. More recent research is needed—and emerging. A 2021 study found that CBN combined with CBD may improve sleep quality, suggesting cannabinoid combinations may be key.
Potential Benefits of CBN
While sleep research is limited, CBN shows promise for:
Sleep Support (Possibly)
Many users report improved sleep with CBN products, especially when combined with CBD. The entourage effect—where cannabinoids work together—may enhance benefits.
Pain and Inflammation
Early research suggests CBN may have anti-inflammatory and pain-relieving properties, similar to other cannabinoids.
Appetite Stimulation
Unlike CBD, CBN may increase appetite—potentially helpful for those struggling to eat due to medical conditions.
Antibacterial Properties
Lab studies have shown CBN has antibacterial effects against resistant bacteria strains, though this hasn't been tested clinically.
How to Use CBN
CBN is typically available as:
- CBN oils/tinctures: Taken under tongue before bed
- CBN gummies: Often combined with CBD and melatonin for sleep
- CBN capsules: Convenient, consistent dosing
- Full spectrum products: Contain CBN along with other cannabinoids
Timing: Take CBN 30-60 minutes before bed for potential sleep benefits.
Dosing: Start with 5-10mg and adjust based on effects. CBN products are often lower-dosed than CBD.
CBN vs Melatonin for Sleep
- Melatonin: Hormone that regulates sleep-wake cycles. Well-researched, works for many people, but can cause grogginess.
- CBN: May promote relaxation and support sleep through different mechanisms. Less researched but anecdotally effective.
- Combination: Many sleep products combine CBN, CBD, and melatonin for synergistic effects.

CBN derived from hemp (containing less than 0.3% Delta-9 THC) is federally legal under the 2018 Farm Bill. However, because CBN comes from THC degradation, some products may have trace THC amounts. Always check lab reports.
The Bottom Line
CBN has earned its "sleepy cannabinoid" reputation from user experiences, but the scientific evidence is still catching up. It may be most effective when combined with other cannabinoids like CBD rather than used alone.
If you're exploring cannabinoid options for sleep:
- Consider full spectrum products that include CBN naturally
- Try CBN combined with CBD for potential synergy
- Keep expectations realistic—more research is needed
- Track your results to see what works for you
