Cannabinoid Degradation

Cannabinoid degradation refers to the chemical breakdown of cannabinoids—primarily THC and CBD—into secondary compounds through heat, light, oxidation, or enzymatic processes. This occurs naturally during curing, storage, and drying, and can also happen during extraction or consumption. Understanding degradation pathways is essential for seed banks and breeders working on preservation methods, as different cultivars show varying stability profiles. CBN (cannabinol) is a well-documented degradation product of THC oxidation, commonly observed in aged or improperly stored material. Lineage records frequently report that some genetics maintain cannabinoid profiles more stably than others under identical conditions, influencing storage and seed preservation protocols.

Breeders working in preservation genetics and long-term seed stability programs monitor cannabinoid degradation profiles to select for cultivars with superior shelf-life and chemical stability. Understanding which parent lines resist degradation helps inform breeding decisions for seed banking, commercial storage, and heritage preservation initiatives.
