Oxidation Degradation

Oxidation degradation refers to the chemical breakdown of cannabis compounds when exposed to air, light, and heat over time. Primary cannabinoids like THC and CBD gradually convert into secondary compounds—notably CBN (cannabinol)—through oxidative processes. This transformation alters the plant material's chemical profile and is frequently observed in poorly stored or aged samples. Understanding oxidation is critical for preservation protocols, as it directly impacts the stability of cannabinoid ratios and volatile terpene profiles. Breeders and cultivators track oxidation rates when evaluating storage methods and seed longevity. The aroma profile of oxidized cannabis typically shifts from fresh, bright terpene notes toward dull, hay-like, or musty characteristics.

Breeders working in seed preservation and stability genetics study oxidation resistance as part of long-term viability testing. Cultivators and seedbanks monitor oxidation patterns to optimize storage conditions and predict shelf-life performance across different genetic lines.
