What is CBN: Effects, Benefits, Uses, & Legality

Medically Reviewed by Ciera Cammilleri

CBN is one of the minor cannabinoids that is often marketed alongside more familiar compounds like THC and CBD.

In the cannabis plant, there are over 100 compounds called cannabinoids. These naturally occurring molecules interact with the human endocannabinoid system (ECS), which plays a key role in regulating various physiological processes. While THC and CBD are the most well-known and abundant cannabinoids, there are many other compounds, like CBN, that contribute to the "entourage effect" - the synergistic impact of using full-spectrum cannabis products.

So, what exactly is CBN, and how does it affect your cannabis experience? Let's find out.

What You'll Learn

In this article, you'll discover everything you need to know about CBN, a lesser-known cannabinoid found in both cannabis and hemp plants. You will learn:

  • What is CBN?
  • Where does CBN come from?
  • The effects of CBN
  • What is CBN used for?
  • The benefits of CBN
  • Potential risks of CBN
  • The legal status of CBN
  • Which cannabis strains contain CBN
  • How to find products that contain CBN

What is Cannabinol (CBN)?

Cannabinol (CBN) is a cannabinoid found in cannabis plants, including both cannabis and hemp varieties. It is distinguished by a unique molecular structure, characterized by a strong carbon-carbon bond between two benzene rings.

CBN is considered a mild cannabinoid with subtle effects, though it can be psychoactive in larger doses.

CBN forms through a process called oxidation. It is found in aged cannabis plants and mature flowers that have been exposed to light and air. Like other cannabinoids, CBN begins as cannabigerol (CBG), which is the precursor to various cannabinoids. Through decarboxylation (when heat is applied), CBG transforms into (tetrahydrocannabinolic acid) THCA, which then converts into THC. When THC is exposed to oxygen over time, it undergoes oxidation, transforming into CBN. This oxidation process releases water molecules, resulting in the formation of CBN.

What are the Effects of CBN?

Although CBN has been studied less extensively than THC and CBD, research and anecdotal evidence suggest that it shares some common effects with other cannabinoids.

  • Sleep Aid: CBN is often noted for its sedative properties, making it effective in promoting sleep and helping users stay asleep longer. It is frequently used by people seeking natural remedies for insomnia or poor sleep quality.
  • Pain Relief: Some studies have shown that CBN may offer relief from pain, particularly muscle and joint discomfort. It is also thought to be beneficial for those dealing with conditions like fibromyalgia.
  • Neuroprotective: CBN has demonstrated neuroprotective qualities, helping to prevent damage to the nervous system and white matter in certain conditions. This makes it a potentially valuable cannabinoid for supporting brain health.
  • Psychoactive: While CBN is generally non-psychoactive, in higher doses it can produce mild psychoactive effects. This is likely due to its structural similarity to THC, as both compounds are derived from THCA.
  • Entourage Effect: CBN is most effective when combined with other cannabinoids. This synergy is known as the "Entourage Effect," where the presence of other cannabinoids like CBD enhance CBN's benefits and potency. The right combination of cannabinoids can amplify therapeutic effects and provide a more balanced experience.

What is CBN Used For?

CBN is typically not found in isolation but rather as part of broader, full-spectrum cannabis products. While you can find CBN oils, tinctures, or capsules that isolate the cannabinoid, it's more commonly included alongside other cannabinoids in full-spectrum cannabis products. CBN is known to enhance the entourage effect--a phenomenon where cannabinoids, terpenes, and other plant compounds work together synergistically to amplify each other's effects. This makes CBN particularly effective for supporting pain relief, promoting better sleep, and offering neuroprotective benefits.

"Full spectrum" products contain a wide range of cannabinoids, terpenes, and flavonoids that work together to deliver the therapeutic effects found in the natural cannabis plant.

If you see CBN listed alongside other cannabinoids, the combined effects are likely to be more potent and balanced.

Though CBN has been studied for its potential in helping conditions like fibromyalgia, it has not yet been widely pursued for medical use. This is likely due to the difficulty in extracting enough CBN for therapeutic use, making large-scale application impractical.

What are the Benefits of CBN?

  • Sleep Aid: If you're struggling with sleep, consider strains containing CBN. It may help you fall asleep more easily and stay asleep longer.
  • Pain Relief: CBN can enhance the pain-relieving effects of cannabis, particularly when it's part of the entourage effect.
  • Mild Psychoactivity: When paired with THC, CBN's mild psychoactive properties can complement and refine the overall experience.

Are There Health Risks to Consider With CBN?

Like all cannabinoids, CBN is metabolized by the liver, which can lead to potential drug interactions with medications that are also processed by the liver. CBN may either enhance or inhibit the effects of these medications.

It's important to check for cannabis-related drug interactions and consult your doctor if you're taking medications that are metabolized by the liver.

Is CBN Legal?

CBN is legal. As a minor cannabinoid that can be derived from hemp, it is federally legal under the 2018 Farm Bill, and no state has specifically banned or regulated CBN.

While CBN breaks down in the body to produce similar metabolites to THC, it can potentially trigger a positive result on a drug test. However, possession and consumption of CBN-containing products are legal both federally and in all states.

What Cannabis Strains Contain CBN?

CBN forms when THCA in cannabis oxidizes, typically after the plant has been exposed to light and air for an extended period. While all strains can potentially produce CBN if left to age, some strains naturally contain higher levels of it than others. "Widow" strains are known for their higher CBN content and the euphoric effects they produce.

To find out if a strain contains CBN, check the product label or look up its cannabinoid(profile online. Many full-spectrum products will list entourage cannabinoids like CBN.
