Insomnia is a problem that affects millions of people worldwide—from difficulty falling asleep to frequent nighttime awakenings. In 2025, as more and more people seek natural alternatives to pharmaceuticals, cannabis is becoming a star in the fight for better sleep. Two cannabinoids—CBD (cannabidiol) and CBN (cannabinol)—have gained particular attention for their potential relaxation and sedative properties. But how exactly do they work? Is this just another wellness trend or a scientifically backed method? In this article, we explore how CBD and CBN can help with insomnia, based on the latest research, and offer tips on how to safely incorporate them into your nighttime routine. Prepare for a journey into the world of cannabis that can transform your nights!

What are CBD and CBN?

Hemp (Cannabis sativa L.) is a plant containing over 100 cannabinoids, of which CBD and CBN are prominent in the context of sleep. CBD is a non-psychoactive compound that has gained popularity for its anti-anxiety, anti-inflammatory, and analgesic properties. It acts on the endocannabinoid system, which regulates key bodily functions such as sleep, mood, and stress response.

CBN, in turn, is formed by the degradation of THC (tetrahydrocannabinol) and is considered a cannabinoid with potential sedative effects, although research on it is less advanced. In Poland, CBD products are legal as long as they contain less than 0.31 TP3T THC, making them available in pharmacies and specialist shops. Due to its origins in THC, CBN may be subject to stricter regulations, so it's crucial to choose products with laboratory certificates confirming their composition and safety.

How does CBD support sleep?

CBD works by modulating the endocannabinoid system, which plays a key role in regulating the sleep-wake cycle. By interacting with CB1 and CB2 receptors, CBD can influence neurotransmitters like serotonin, which helps reduce anxiety—one of the main causes of insomnia. A 2019 study in The Permanente Journal (The Permanente Journal) showed that 66.7% of participants taking 25mg of CBD daily for a month noticed improved sleep quality, and 79.2% reported reduced anxiety.

Another study from 2023 in Journal of Clinical Sleep Medicine confirmed that CBD in doses of 15-50 mg can increase sleep duration and reduce the number of nighttime awakenings, which is particularly beneficial for people with chronic insomnia. CBD can also relieve pain that often makes falling asleep difficult, for example, in people with arthritis or fibromyalgia. This allows CBD to create the ideal conditions for restful sleep by indirectly reducing these obstacles.

How does CBN affect sleep?

CBN, nicknamed the "sleep cannabinoid," gained popularity thanks to anecdotal reports of its sedative properties. It is produced when the THC in cannabis ages and oxidizes, making it slightly psychoactive but significantly milder than THC. Initial studies, such as a 1975 experiment in mice, showed that CBN could increase sleep duration (PubMed).

Although clinical data is limited, users report that CBN helps them fall asleep faster and sleep deeper, especially when combined with CBD. In 2025, CBN products such as oils and gummies are becoming increasingly popular, especially in 1:1 CBD:CBN formulas, which may work synergistically through the entourage effect. However, the lack of large-scale clinical trials means that CBN's effectiveness is based primarily on user experience, requiring caution when using it.

CBD and CBN Compared to Fight Insomnia

CBD and CBN have different mechanisms of action, making them complementary in the treatment of insomnia. CBD works indirectly, relieving anxiety, stress, and pain, which are common causes of difficulty falling asleep. Its effects are well-documented, with numerous studies confirming its effectiveness in improving sleep quality. CBN, on the other hand, has a potentially more sedative effect, which may directly support the process of falling asleep and promoting deeper sleep. However, research on CBN is less advanced, and its effects may vary more depending on dose and individual response.

Products combining CBD and CBN, such as 1:1 oils, are gaining popularity in 2025 because they can offer synergistic benefits—relaxation from CBD and sedation from CBN. The key is to test small doses to find the perfect combination that best suits your needs.

How to use CBD and CBN to improve sleep?

To effectively use CBD and CBN in the fight against insomnia, it is worth following a few practical rules:

Start with low doses: The recommended starting dose is 5–25 mg of CBD or 2–10 mg of CBN, taken 30–60 minutes before bed. Too high a dose can paradoxically cause hypervigilance, especially with CBD.
Select the appropriate product form: Sublingual oils work quickly (15-30 minutes), which is ideal for those who want to fall asleep quickly. Gummies and capsules have a longer duration of action (4-8 hours), which helps maintain sleep throughout the night. Vaping is less recommended before bed due to its quick but short-lived effects.
Use regularly: The effects may require several days of use to reach their full effectiveness. Keep a sleep journal to monitor your progress.
Choose quality: Look for products with laboratory certificates that confirm the absence of THC and contaminants (Leafly). CBD products are widely available in Poland, but CBN may require more thorough testing.
Consult your doctor: If you are taking sleeping pills, anti-anxiety medications, or other medications, consult your doctor to avoid interactions.

For example, you can add a few drops of CBD oil to chamomile tea or eat a CBN gummy as part of your evening ritual. It's important to create a calm environment—turn off screens, dim the lights, and let the cannabinoids do their work.

Potential side effects and precautions

CBD and CBN are generally well-tolerated, but they can cause side effects, especially at higher doses. The most common include:

Dry mouth: A typical cannabinoid effect that can be alleviated by drinking water.
Dizziness: Especially with CBN, which can be slightly psychoactive.
Fatigue during the day: Too high doses may cause drowsiness in the morning.
Changes in appetite: CBD may affect appetite, although usually to a lesser extent than THC.

CBN, as a cannabinoid derived from THC, can produce subtle psychoactive effects, requiring caution in individuals sensitive to cannabinoids or with a history of mental illness. Both compounds can interact with medications metabolized by the liver, such as benzodiazepines and antidepressants, so consulting a doctor is essential. It's also important to avoid products with unknown ingredients, which may contain trace amounts of THC, which can be problematic in drug tests or for those avoiding psychoactive effects.

In 2025, CBD and CBN are promising natural remedies for insomnia, revolutionizing the way we approach sleep. CBD, with its anti-anxiety and pain-relieving properties, creates the ideal conditions for restful sleep, while CBN can act more sedatively, promoting deeper rest. While CBD research is more advanced, CBN is gaining traction thanks to anecdotal reports and preliminary data.

The key to success is low doses, high-quality products, and consistent use. If you struggle with insomnia, hemp can be your ally—provided you approach it with caution and awareness. Try CBD or CBN and discover how the natural power of hemp can transform your nights!
