CBD might be familiar to you, but its cousin cannabinol (CBN) has started making waves because it helps people sleep better. CBN comes from tetrahydrocannabinol (THC) that breaks down naturally when exposed to heat, light, and oxygen.
CBD doesn't have any psychoactive effects, but CBN can make you feel slightly high in larger doses - though it's only about 25% as strong as THC. Scientists are most excited about CBN's ability to improve sleep. A newer study showed that people who used a mix of CBN, CBD, and THC slept 72 extra minutes each night. On top of that, 82% of users said they stayed asleep through the night. Your body's endocannabinoid system responds to CBN and helps control sleep, mood, and pain.
People often call CBN "the sleepy cannabinoid," and by now, you'll learn why this name fits so well. This natural compound could be exactly what you need, especially when you have trouble sleeping or need pain relief.
CBN explained: What it is and where it comes from
Cannabinol (CBN) is a fascinating member of the cannabis family with a unique story that sets it apart from other cannabinoids. Scientists Barlow Wood, Newton Spivey, and Easterfield found CBN in 1896 while studying hashish. This makes CBN the first cannabinoid anyone isolated from cannabis extract.
CBN is quite different from its well-known cousins CBD and THC. Fresh cannabis plants contain very little CBN. The compound only appears as cannabis ages naturally over time.
How CBN is created from THC over time
CBN forms differently than other cannabinoids. While most cannabinoids come from acidic precursors, CBN comes directly from THC's degradation. This change happens when THC is exposed to:
-
Oxygen (air)
-
Heat
-
Light (especially UV light)
-
Extended storage time
These elements trigger an "aromatization" reaction in THC's menthyl portion. The longer cannabis stays exposed to these elements, the more THC turns into CBN. Old or poorly stored cannabis products usually have higher CBN levels.
Research shows that THC changes to CBN faster in strongly acidic conditions and high temperatures (40-70°C). Studies of cannabis stored in different ways showed that THC broke down and CBN increased faster during the first year, especially when exposed to light at room temperature (22°C).
Storing cannabis at -20°C works best to stop this change, which helps preserve THC content.
Why CBN is gaining attention in 2025
CBN's special properties have caught the attention of researchers and consumers. People once overlooked CBN and focused on THC and CBD. Now CBN has carved its own space in the wellness market for good reasons.
CBN produces milder effects than THC. It connects to the same CB1 receptors in the brain as THC, but its binding strength is nowhere near as strong - about ten times weaker. This creates a gentler interaction with the endocannabinoid system. People who want subtle effects without feeling too intoxicated find this appealing.
The legal situation has helped CBN grow popular. The 2018 Farm Bill made CBN extracts from Cannabis sativa L federally legal in the US, as long as they contain no more than 0.3% THC. This opened new opportunities for product development and research.
Research suggests CBN might help with several health issues. Studies point to benefits for sleep, pain management, and reducing inflammation. Scientists are also looking at how CBN might help with neurological conditions like fibromyalgia.
The wellness industry has created many CBN products to meet growing demand. People can now choose from oils, tinctures, gummies, and topicals to add this cannabinoid to their wellness routines.
Research in 2025 continues to reveal more about CBN's potential. This once-forgotten compound has become a key player in today's cannabis world.
CBN vs CBD: Understanding the differences
CBD and CBN might sound alike, but they affect your body in completely different ways. The cannabis industry keeps evolving, and knowing these differences helps you pick the right product that fits your needs.
Psychoactive effects: None vs mild
The biggest difference between these cannabinoids shows up in how they affect your mind. CBD won't give you any mental changes or make you feel "high". Many people choose it because they want the health benefits without any mind-altering effects.
CBN comes from THC breaking down and has mild psychoactive properties. It's nowhere near as strong as THC (about 25% of THC's strength), but larger doses of CBN can still create subtle mind-altering effects.
Your endocannabinoid system responds differently to each compound. CBD doesn't stick to CB1 receptors in your brain, so you won't feel any euphoria. CBN does attach to these receptors, but much more weakly than THC. Some sensitive people might notice its effects.
Availability and extraction methods
CBD has become much more popular than CBN. A 2023 survey showed that 72% of people knew about CBD, while only 17% had heard of CBN. This gap affects how easy it is to find these products.
Hemp plants naturally produce lots of CBD. You can find it in oils, tinctures, gummies, topicals, and even shampoos. CBD extraction has become a refined process, making it more affordable and accessible to more people.
Plants don't directly produce CBN. Manufacturers must wait for THC to age and break down on its own. Heat, light, or oxygen exposure over time causes this change. This complex process makes CBN products more expensive and harder to find.
Both cannabinoids face challenges with bioavailability - getting into your bloodstream. Scientists have found that fluorination techniques might boost absorption rates. The way you take these compounds matters too. Vaping or putting them under your tongue works faster but doesn't last as long. Edibles take longer to kick in but provide longer-lasting effects.
Which is better for sleep or anxiety?
CBN seems to work better for sleep. Many companies market it as a sleep aid because it can make you drowsy - great news if you have insomnia. Users often say they sleep better with CBN products. Research shows THC combined with CBN made people more sleepy than just THC alone.
CBD helps with sleep too. A 2019 study found that 66.7% of people slept better after taking 25-175mg of CBD daily. Some studies show that CBD works just as well by itself as it does with CBN.
CBD takes the lead in fighting anxiety. Research backs up its anxiety-reducing effects. The Permanente Journal published a study where about 79% of CBD users felt less anxious within a month. CBN hasn't shown the same results for anxiety, mainly because we don't have enough research yet.
Many new products tap into the full potential of both cannabinoids. They combine CBD's anxiety-fighting power with CBN's sleep benefits. This all-encompassing approach works great if you're dealing with both issues at once.
Top CBN benefits you should know
Scientists continue to study cannabinoids, and CBN has shown several promising health benefits. Let's look at how CBN products might help your wellness journey.
Improved sleep quality
CBN has earned its nickname as "the sleepy cannabinoid," and with good reason too. A newer study, published in a double-blind, randomized, placebo-controlled format, showed that people taking 20 mg of CBN woke up less during the night and slept better than those taking a placebo. CBN helped people stay asleep all night without making them feel tired the next day.
CBN by itself hasn't proven to be a sedative yet. However, it works better at supporting sleep when combined with other cannabinoids and terpenes. This explains why many sleep-focused CBN products include small amounts of other cannabis compounds.
Reduced pain and inflammation
CBN shows impressive anti-inflammatory properties. Scientists found that CBN reduced pro-inflammatory interleukins in an inflamed cell model. This could help people with inflammatory conditions.
The compound works well for pain relief. A 2019 study showed that CBN eased nerve growth factor-induced sensitization in muscle tissue by activating CB1 receptors. Scientists also found that CBN reduced myofascial pain in rats through CB2 receptors, which help block pain and inflammation.
Potential for calming anxiety
While research is still new, CBN looks promising for anxiety management. It can help you relax without strong psychoactive effects. CBN works with your endocannabinoid system—specifically CB1 and CB2 receptors—to tackle anxiety both physically and mentally.
CBN might also help ease anxiety by improving your sleep and reducing pain, two things that often make anxiety worse.
Support for neurological health
The most exciting news comes from CBN's neuroprotective properties. Scientists at the Salk Institute found that CBN helps protect the brain from aging and neurodegeneration. Their research showed that CBN shields mitochondria—your cells' energy centers—in neurons, which keeps them working properly.
This protective quality makes CBN a possible treatment for:
-
Alzheimer's disease
-
Parkinson's disease
-
Traumatic brain injury
One study showed that CBN helped cells survive better than other cannabinoids, including CBD and THC. Scientists have now created improved versions of CBN that could help with various brain disorders.
Yes, it is exciting that CBN's ability to protect mitochondria suggests benefits beyond brain health, potentially supporting cell health throughout your body.
How to take CBN: Choosing the right product
Your specific needs and priorities determine the right CBN product for you. Several options are accessible to more people now, and knowing how each delivery method works will help you make better choices.
Sublingual oils and tinctures
Sublingual CBN products give you faster absorption with 20-30% bioavailability. You should place a few drops under your tongue and hold them for 30-60 seconds before swallowing. These oils start to work within 10-15 minutes, which makes them the quickest way to get relief.
Most experts suggest starting with half to one full dropper. CBN oil strength varies significantly—a 500mg bottle contains approximately 16.7mg of CBN per 1ml dropper, while a 1000mg bottle gives you about 33.3mg per dropper.
Gummies and edibles
CBN gummies deliver consistent, pre-measured doses with 10-20% bioavailability. Each piece typically contains 10-20mg of CBN, and you'll feel the effects 45-60 minutes after eating them.
Manufacturers recommend you start with half a gummy and slowly increase the dose if needed. These gummies are great for extended relief, lasting 4-6 hours—perfect to help you sleep through the night.
Topicals for localized relief
CBN topicals target pain directly on affected areas without entering your bloodstream. Products like pain relief sticks blend CBN with other cannabinoids and ingredients like menthol to create warming and cooling sensations.
You can massage a generous amount onto sore spots and let the effects sink in deeply. Feel free to apply topicals throughout the day as needed—they won't make you drowsy.
Combining CBN with CBD for better results
CBN and CBD create mutually beneficial effects—a principle known as the entourage effect. These cannabinoids work together to tap into the full potential of each other, often proving more effective than using either one alone.
CBD:CBN combination products work best for sleep when taken 5-60 minutes before bedtime, depending on how you take them. CBD helps balance CBN's mildly psychoactive properties while helping you relax more deeply.
Remember to ask your doctor about proper dosing, start with a low dose, and buy only from trusted sources.
What to know before trying CBN
You need to think over a few safety measures before adding CBN to your wellness routine. People's interest in this cannabinoid grows faster every day, so understanding safety basics will help you have a better experience.
Possible side effects and how to avoid them
CBN has an excellent safety profile, but some users might notice mild side effects. Most people report drowsiness, dry mouth, dizziness, and next-day grogginess. These effects usually show up only with high doses and go away naturally as your body processes the compound.
To keep side effects minimal:
-
Start taking CBN at home to see how your body responds
-
Stay away from mixing it with alcohol or other sleep aids
-
Lower your dose if you notice unwanted effects
CBN might make THC's psychoactive effects stronger when you take both together. Your liver processes certain medications differently when CBN is present.
How to start with the right dosage
Finding your optimal CBN dose takes time and careful attention. Expert advice suggests starting with just 2-5mg. You can slowly increase until you get the results you want. Most people find their sweet spot between 5-10mg. Effective doses range from 2.5mg to 50mg based on individual factors.
New users should start with the smallest possible amount and adjust based on how they feel. This careful approach helps you avoid feeling too sedated while you find what works best for your body.
Talking to your doctor before use
Make sure to check with your healthcare provider before trying CBN, especially if you:
-
Take medications that affect brain chemistry
-
Are pregnant or breastfeeding
-
Have liver or kidney conditions
Your doctor can review potential drug interactions since CBN might change how your body handles certain medications. This becomes even more significant if you take blood thinners or medications that make you drowsy.
Buying from trusted sources
Product quality makes all the difference when you're buying CBN products. These items don't have FDA regulation, so third-party testing is vital for safety. Before you buy:
Look for products that come with certificates of analysis (COAs) from independent labs. These documents show cannabinoid content and prove there are no contaminants like pesticides, heavy metals, or mold.
Check the lab results' date (should be within 12 months) and make sure CBN levels match the label. Read customer feedback both on the company's website and independent platforms.
Final Thoughts
CBN is a remarkable cannabinoid that works differently from its popular relative, CBD. Research shows it lives up to its nickname "the sleepy cannabinoid" by helping people sleep better and longer. It also reduces pain, fights inflammation, eases anxiety, and supports brain health. These benefits make it a great addition to your wellness routine.
Your specific needs will determine the right CBN product for you. You can choose from fast-acting sublingual oils, precise-dose gummies, or targeted topicals. Start with small doses to see how your body responds. The entourage effect might boost your results, especially when you have sleep issues and combine CBN with CBD.
Your healthcare provider should know before you start using CBN, particularly if you take other medications. Quality matters too - buy from trusted sources that use third-party testing. This will give you safe products with the right cannabinoid levels.
CBN research and product development show great promise. Scientists are still working to realize its full potential, and knowing about this compound helps you remain competitive. While CBN might not be as accessible to more people as CBD or THC right now, its unique benefits make it one of the most valuable compounds that ever spread from the cannabis plant.
