Thc To Cbn Oxidation

THC-to-CBN oxidation describes the natural chemical degradation pathway in which tetrahydrocannabinol (THC) converts to cannabinol (CBN) over time, particularly when cannabis plant material is exposed to heat, light, and oxygen. This process is a well-documented aspect of cannabis chemistry and storage science, not a desired outcome in most cultivation and preservation contexts. The oxidation rate varies based on environmental conditions, storage methods, and initial plant genetics. Understanding this conversion is relevant for breeders selecting for storage stability and for researchers studying cannabinoid stability profiles across different chemotypes.

Breeders working in preservation genetics and seed banking consider oxidation resistance when selecting parent plants. Lines showing slower THC-to-CBN conversion under standard storage conditions are often retained for seed stock maintenance programs, as they better maintain their chemotype integrity over multi-year storage periods.
