Cannabinoid Thermal Degradation

Cannabinoid thermal degradation refers to the chemical breakdown of cannabinoids (THC, CBD, CBN, etc.) when exposed to heat above their stability thresholds, typically 160–200°C depending on the compound. This process is critical in breeding, curing, storage, and consumption contexts, as degradation alters cannabinoid profiles and can produce secondary compounds like CBN. Breeders and cultivators track stability profiles across strains to understand how cannabinoids behave under different conditions. Understanding degradation kinetics helps inform optimal drying, curing, and storage protocols to preserve target cannabinoid ratios. This phenomenon also explains why cannabinoid potency and composition shift over time in improperly stored material.

Breeders evaluate cannabinoid stability as part of strain characterization, particularly when developing lines intended for specific cannabinoid profiles or extraction methods. Stability data informs recommendations for post-harvest handling and helps predict how a strain's chemistry will evolve during cure and storage.
