CBN (cannabinol) is a cannabinoid that forms as THC gradually degrades over time through exposure to heat, light, and oxygen. Elevated CBN levels may indicate aging cannabis material or storage conditions that have affected cannabinoid stability. Testing CBN can provide insight into product shelf life and cannabinoid degradation. For producers and retailers, CBN data can serve as a useful quality indicator — particularly for products with longer supply chains or extended shelf exposure — helping identify inventory that may have experienced potency loss due to improper storage conditions.
