Cannabinol (CBN): A Scientific Guide to the Non-Intoxicating Cannabinoid
Cannabinol (CBN) is a non-psychoactive cannabinoid that forms naturally from THC as cannabis ages. Although classified as a minor cannabinoid, CBN is gaining major attention in the wellness world — especially in sleep support, calm-focused formulations, and anti-inflammatory applications.
Unlike CBD or THC, CBN is not directly biosynthesized by the cannabis plant. Instead, it’s the oxidative breakdown product of tetrahydrocannabinolic acid (THCA), forming over time when cannabis is exposed to light, heat, or oxygen.

Chemical Structure and Biosynthesis
Chemical Properties
CBN has the molecular formula C₂₁H₂₆O₂. Structurally, it resembles THC but lacks the double bond responsible for THC’s intoxicating effects — explaining CBN’s non-psychoactive profile

Biosynthetic Pathway
CBN is not produced directly by cannabis biosynthesis. It forms via oxidative degradation of THCA:
- CBGA → THCA (via THCA synthase)
- THCA → THC (via heat/decarboxylation)
- THC → CBN (via oxidation over time or with light exposure)

Molecular Pharmacology of CBN
Cannabinoid Receptor Interactions
CBN has low affinity for both CB1 and CB2 receptors:
- CB1 (CNS): Weak agonism → No intoxication
- CB2 (immune tissues): Suggests role in inflammatory balance and immune modulation

Non-Cannabinoid Targets
CBN also interacts with:
- TRPV2 channels – Potential influence on pain, inflammation, and temperature response
- PPARγ – Nuclear receptor tied to metabolic regulation and immune responses
- 5-HT1A – May play a role in mood balance and calming effects

Enzymatic Modulation
CBN may indirectly influence the FAAH enzyme, responsible for breaking down anandamide, an endogenous cannabinoid linked to mood, pain regulation, and calm.

Pharmacokinetics: Absorption, Metabolism & Bioavailability
Absorption & Bioavailability
CBN bioavailability is improved with MCT oil for first-pass metabolism providing a higher efficacy like our Sleep Gummies.
📚 Source: Frontiers in Pharmacology
Metabolism & Excretion
CBN is metabolized by cytochrome P450 enzymes (particularly CYP2C9 and CYP3A4).
- It is excreted through urine and bile after hydroxylation and conjugation.

How Long Does CBN Stay in Your System?
CBN can remain detectable in your system for 2–5 days, though this varies based on:
- Frequency of use: Regular use may lead to accumulation and longer retention in the body.
- Dosage: Higher doses typically take longer to clear from your system.
- Body fat percentage: CBN is lipophilic, meaning it binds to fat — individuals with higher body fat may retain CBN longer.
- Metabolism: Faster metabolic rates can lead to quicker processing and elimination of CBN.
- Method of consumption: Inhalation (e.g., vaping): rapid onset, shorter duration
- Sublingual (e.g., oils): moderate onset, moderate duration
- Oral ingestion (e.g., edibles or capsules): slower onset, longer duration
For daily users or those using higher doses, traces may remain for up to two weeks.
⚠️ Side Effects
Known side effects are generally mild and may include:
- Drowsiness or fatigue
- Dry mouth
- Diarrhea
- Appetite changes
⚠️ Drug Interactions
CBN is metabolized by cytochrome P450 enzymes, which are also responsible for breaking down many medications.
Potential interactions include:
- Blood thinners (e.g., warfarin)
- Anti-epileptics
- SSRIs
- Benzodiazepines
- NSAIDs
🩺 Always consult a healthcare professional before combining CBN with prescription medications.
Analytical & Extraction Methods
Supercritical CO₂ Extraction
CBN is typically extracted via:
- Supercritical CO₂ – Clean, safe, solvent-free
- Ethanol extraction – May be used with aged cannabis to maximize CBN content

Chromatographic Testing
- HPLC (High-Performance Liquid Chromatography) is the gold standard for quantifying CBN and other cannabinoids.
- GC-MS (Gas Chromatography–Mass Spectrometry) is often used for advanced purity and degradation profiling.

Sustainability and the Role of Hemp in CBN Extraction
Hemp as a Source for CBN
Although CBN forms more in aged cannabis, hemp-derived CBN is now extracted intentionally from stored or oxidized biomass.
Environmental Benefits
- Hemp cultivation supports carbon sequestration, improves soil quality, and requires less water than traditional crops
