Oxidation And Degradation

Oxidation and degradation refer to chemical processes that alter cannabis flower composition over time, particularly affecting cannabinoid and terpene profiles. When plant material is exposed to oxygen, heat, or light, cannabinoids like THC can oxidize into CBN (cannabinol), while volatile terpenes may evaporate or break down into secondary aromatic compounds. These processes are not inherently desirable or undesirable—they represent natural aging pathways that breeders and cultivators monitor and sometimes deliberately manage. Understanding oxidation is essential for seed preservation, curing protocols, and predicting how a strain's aroma and chemical profile will shift from harvest through storage. Growers and breeders working with long-term seed banks or heirloom genetics frequently study oxidation patterns to maintain genetic integrity across generations.

Breeders track oxidation stability when selecting for shelf-life and consistency in stored flower and seeds. Cultivators managing curing and storage environments use oxidation knowledge to preserve desired terpene profiles and prevent unwanted degradation of cannabinoids.
