Cannabinoid Degradation Curves

Cannabinoid degradation curves describe how THC, CBD, and other cannabinoids chemically transform over time under various storage and environmental conditions. These curves are essential reference tools in cannabis breeding and preservation, documenting how heat, light, oxygen, and humidity accelerate the conversion of THC to CBN (cannabinol) and other oxidized metabolites. Understanding degradation kinetics helps breeders select for genetic stability, guides cultivators on harvest timing and curing protocols, and informs seed banks on proper storage methodology. Breeders working in this category often study cultivar-specific degradation rates to optimize shelf life and cannabinoid profile consistency. Degradation curves are commonly mapped through HPLC analysis across weeks or months, providing quantitative data rather than visual or sensory assessment alone.

Breeders use degradation curve data to select parent plants with slower cannabinoid breakdown rates, improving final product longevity and consistency across batches. Understanding how specific cultivars degrade informs seed storage protocols and helps develop cultivars with more stable cannabinoid profiles under sub-optimal conditions.
