The entourage effect is a hypothesis that the many compounds in cannabis interact so that the whole plant acts differently from purified THC or CBD. The term comes from endocannabinoid research by Ben-Shabat, Mechoulam and colleagues in 1998; Russo (2011) extended it to cannabinoid-terpene interactions. Critics such as Cogan (2020) argue that much of it is marketing, and controlled human tests of specific terpene-cannabinoid combinations have so far been limited and mixed.
In practice
The phrase is used to sell "full-spectrum" products and to argue against isolates and distillates. For growers, there is a firmer, separate point: people consistently report that aroma matters to their experience, and one survey study (Plumb et al. 2022) found that aroma predicted reported subjective effects better than THC percentage. That supports caring about terpenes and VSCs without endorsing specific synergy claims. GenetixBay makes no medical claims; effects are only reported.
Don't confuse with
- Terpene profile: a measurement; the entourage effect is a hypothesis about what the measurement means.
- Full-spectrum: a product label, not a tested outcome.
Myth check
Evidence: Contested. Claims that a particular terpene "steers" effects are not established. See Mythbusters.
THC (Δ9-tetrahydrocannabinol) is the neutral, decarboxylated cannabinoid mainly responsible for cannabis's reported intoxicating effects; the living plant makes it almost entirely as THCA.CBD (cannabidiol) is a non-intoxicating neutral cannabinoid formed when CBDA decarboxylates; hemp-type and CBD-dominant cannabis make it mainly as CBDA in their trichomes.Distillate is a highly refined cannabis oil in which cannabinoids, usually THC or CBD, have been separated from most other compounds by distillation, leaving a clear, almost odourless oil.Terpenes are volatile hydrocarbon compounds built from five-carbon isoprene units; in cannabis they are made in the trichome heads and are a major part of aroma and flavour.Volatile sulfur compounds (VSCs) are trace sulfur-containing aroma molecules, especially prenylated thiols, that give cannabis its skunky, gassy smell at concentrations far below terpenes.A terpene profile is the measured mix of terpenes in a sample, reported as each compound's % w/w and the total, used to describe and compare cultivar aroma chemistry.A cannabinoid is any compound that binds the body's cannabinoid receptors or shares the typical cannabis terpenophenolic structure; the plant-made ones are phytocannabinoids such as THCA and CBDA.An isolate is a concentrate refined to one cannabinoid at very high purity, often 99% or more, usually a white crystalline powder such as CBD or THCA isolate.
