Entourage Theory

The Entourage Theory posits that cannabinoids, terpenes, flavonoids, and other plant compounds interact synergistically rather than functioning in isolation. This concept emerged from cannabinoid research in the 1990s and has become foundational to modern cannabis breeding and product development discussions. Breeders and researchers often examine full-spectrum profiles—not just THC or CBD levels alone—when evaluating cultivar effects and characteristics. The theory suggests that a strain's terpene profile, minor cannabinoids, and plant material composition collectively shape the plant's chemical expression. While peer-reviewed evidence remains limited, the framework has influenced how the industry approaches strain selection, extraction methods, and phenotype evaluation.

Breeders working within Entourage Theory frameworks prioritize maintaining or selecting for diverse cannabinoid and terpene profiles rather than maximizing single compounds. This approach has led to renewed interest in landrace genetics, CBD-rich cultivars, and preserved minor cannabinoid expression as breeding targets.
