CBN

A minor, non-intoxicating cannabinoid that forms as THC ages, widely marketed for sleep on evidence that does not yet support the claim.

CBN for Pets: What the Evidence Actually Shows

CBN (cannabinol) is a minor, non-intoxicating cannabinoid that forms as THC ages. It is marketed almost everywhere as "the sleepy cannabinoid." The peer-reviewed literature does not support that reputation, and we would rather tell you so than repeat it.

Here is what CBN is, where it comes from, and where the evidence currently stands.

What Is CBN?

CBN is an oxidative degradation product. When THC is exposed to heat, light and oxygen over time, it breaks down and CBN is what remains. Fresh hemp contains very little of it; aged material contains more.

That origin story sounds alarming until you follow it through: the degradation is what removes the intoxicating character. CBN is a different molecule from THC and is described in the literature as non-intoxicating, with markedly weaker central effects.

Where CBN Sits Among the Cannabinoids

Hemp produces well over a hundred cannabinoids. CBD is the most abundant, with CBG, CBC and CBDV present in smaller amounts. CBN is different from all of them in that the plant does not really make it — time does.

This is also why CBN is not a headline compound in a fresh, properly stored full-spectrum hemp extract. An extract rich in CBN is generally an extract that has aged.

How Cannabinoids Interact With Your Pet's Body

Dogs, cats and horses all have an endocannabinoid system — a network of receptors involved in keeping the body in balance. Cannabinoids from hemp interact with that system, which is the mechanism behind the entourage effect.

Cornell's Riney Canine Health Center is a good plain-English primer on cannabinoids in dogs.

The Sleep Claim, Examined

A 2021 review in Cannabis and Cannabinoid Research looked specifically at CBN and sleep and concluded there is insufficient published evidence to support sleep-related claims. Most of the underlying human work dates from the 1970s and 1980s, with small samples and no validated sleep measures. You can read it here.

There are also no published canine efficacy studies on CBN. Anyone telling you CBN is proven to make your dog sleep is ahead of the science.

Why We Say This Out Loud

We have spent since 2016 breeding our own hemp genetics, growing them on our Longmont, Colorado farm using organic growing practices, and formulating in-house. We also commissioned real university research rather than borrowing someone else's — including a 90-day canine study overseen by Dr. Robin Downing with researchers from Colorado State University.

A brand that funds its own studies does not get to wave away inconvenient evidence elsewhere. CBN's reputation outran its data, and that is worth knowing before you pay a premium for it.

Is CBN Safe for Pets?

CBN is non-intoxicating and hemp-derived cannabinoid products have a well-established safety record in animals — Cornell cites National Animal Supplement Council data showing fewer than two adverse events per million products sold annually over a decade, most commonly mild digestive upset or drowsiness.

As with any supplement, start low, go slow, and talk to your veterinarian first if your pet is on medication.

What We Make Instead

Our products are full-spectrum: the plant's whole cannabinoid and terpene profile, third-party tested every batch, in organic coconut oil, hemp seed oil or olive oil. For everyday calm support, see Calming Support; browse the full range at CBD Hemp for Dogs and CBD Hemp for Cats.

Frequently Asked Questions

What is CBN and how is it different from CBD? CBN forms as THC degrades over time; CBD is produced by the plant directly and is far more abundant. Both are non-intoxicating.

Is CBN the same as THC? No. CBN is what THC becomes as it breaks down, and the resulting compound is not intoxicating.

Does CBN make dogs sleepy? The evidence does not establish that. A 2021 peer-reviewed review found insufficient published support for CBN's sleep claims, and no canine studies exist.

Is CBN safe for dogs? Hemp cannabinoids have a strong safety record in animals, with mild digestive upset or drowsiness the most commonly reported effects. Check with your veterinarian if your pet takes medication.

Does CBN show up in full-spectrum hemp oil? Sometimes, in trace amounts, since some THC degrades naturally over time. A fresh, well-stored extract will contain very little.

Is CBN legal? Cannabinoids from hemp containing no more than 0.3% THC fall under the 2018 Farm Bill, though state rules vary.

Is CBN more powerful than CBD? No. CBN occurs in far smaller amounts, is far less studied, and its reputation rests on limited older research rather than on strength.

Does CBN make dogs calm or sleepy? The published evidence does not establish that. The 2021 review found insufficient support for CBN's sleep claims, and no canine studies exist.

Does CBN calm anxiety? There is no published evidence establishing that CBN affects anxiety in dogs, cats or horses — no canine trials exist, and the human work behind CBN's reputation was about sleep rather than anxiety, and was thin even there. Anyone marketing CBN to you for anxiety is ahead of the science. If your pet is anxious, start with your veterinarian.

Is CBN or CBD better for a nervous dog? CBD is far better studied, and it is the cannabinoid veterinary research has actually concentrated on. Neither is a treatment for anxiety, but if you are choosing between them on evidence rather than marketing, CBD is the one with a literature behind it.

What form of hemp works best for calm support? A full-spectrum extract in an oil, because the amount can be adjusted precisely to your pet's weight. See Calming Support.

Can I give CBD and CBN together? Full-spectrum extracts naturally contain multiple cannabinoids together. Discuss any specific combination with your veterinarian.
