Cannabinoid Density

Cannabinoid density describes the concentration of cannabinoids (CBD, THC, CBN, etc.) per unit of dried plant material, typically measured in milligrams per gram or percentage by weight. This classification emerged as analytical testing became standard in cannabis breeding, allowing breeders to distinguish between high-potency cultivars and lower-concentration material. Density varies significantly across strain families and growing conditions, with some cultivars naturally accumulating cannabinoids at much higher rates than others. Modern breeding programs often select for specific cannabinoid density targets to meet market demand or research objectives. Density differs from cannabinoid *profile* (the ratio of different cannabinoids) and cannabinoid *expression* (total yield per plant).

Breeders use cannabinoid density as a primary selection criterion when developing cultivars for specific applications—high-density lines for extraction or concentrate production, lower-density lines for balanced consumption or breeding diversity. Density is heritable and can be tracked across generations to stabilize desired trait ranges.
