Entourage Effect
Definition
The entourage effect is the theory that cannabinoids and terpenes work synergistically — that whole-plant extracts produce different effects than isolated compounds.
First proposed by Israeli researcher Raphael Mechoulam in 1998, the entourage effect explains why some users report different experiences from full-spectrum CBD versus pure CBD isolate, even at the same total CBD dose.
The theory is widely accepted directionally — peer-reviewed studies have supported synergy between specific cannabinoid pairs and between cannabinoids and terpenes — but the precise mechanisms are still being researched. The practical takeaway: full- and broad-spectrum products often produce noticeable effects at lower CBD doses than isolate does.
