Why does medicinal cannabis remain so popular? Is it the ‘entourage effect’?
Australian demand for medicinal cannabis remains high despite limited evidence of efficacy. One proposed explanation for this disconnect is the 'entourage effect', which suggests that non-cannabinoid components of whole-plant formulations, typically missing from the standardised products subject to trial, enhance therapeutic outcomes. While advocates cite observational studies and overseas usage patterns, there is no clinical or in vitro evidence supporting this hypothesis. Furthermore, Australian usage patterns do not suggest a preference for whole plant products. Until further evidence emerges from well-designed trials, the entourage effect remains speculative and claims regarding the benefits of whole-plant preparations must be interpreted as such.
