Drug Type Vs Fiber Type

Drug-type and fiber-type cannabis represent distinct chemovars selected for different end-uses, historically influencing terpene profiles and secondary metabolite expression. Drug-type cultivars, bred for cannabinoid potency, often develop more complex volatile aromatic profiles with emphasis on myrcene, limonene, and caryophyllene. Fiber-type (hemp) cultivars, selected for stalk strength and cellulose yield, typically show lower overall terpene complexity and reduced volatile expression. These distinctions are genetic—not merely environmental—and reflect centuries of parallel selective breeding in different regions. Understanding the chemotype difference is foundational to interpreting terpene data across seed banks and breeding records.

Breeders working to reintroduce fiber-type traits into modern cultivars must manage terpene profile shifts, as cannabinoid-focused selection often amplifies volatile production. Conversely, hemp breeders selecting for agronomic traits document terpene suppression as a byproduct, relevant to regulatory compliance and cultivar stability across generations.
