Cannabinoid Degradation Pathways

Cannabinoid degradation pathways describe the enzymatic and chemical processes by which cannabinoids like THC and CBD transform over time due to heat, light, oxygen, and microbial activity. Understanding these pathways is essential for breeders and cultivators seeking to preserve cannabinoid profiles during storage, processing, and breeding selection. Degradation can alter potency, create new minor cannabinoids (such as CBN from THC oxidation), and affect the overall chemical fingerprint of plant material. Different environmental conditions—temperature fluctuations, humidity, and UV exposure—accelerate or slow degradation rates. Lineage records and breeding programs increasingly document how genetic factors influence cannabinoid stability, with some cultivars showing greater resistance to oxidative breakdown than others.

Breeders working in cannabinoid preservation focus on selecting for plant genetics and storage-friendly traits that minimize unintended cannabinoid conversion. Understanding degradation pathways helps inform seed selection, drying protocols, and long-term seed banking strategies.
