An entourage effect: inactive endogenous fatty acid glycerol esters enhance 2-arachidonoyl-glycerol cannabinoid activity

Summary & key facts

Researchers did lab experiments with natural fat-like molecules found in the body and showed that some of these molecules do nothing by themselves but make a natural cannabinoid called 2-arachidonoyl-glycerol (2-AG) work stronger. This finding supports the idea of an "entourage effect," where inactive companion molecules change how an active signaling molecule behaves. The work was done in laboratory tests, not in people, so it shows a possible biological trick but does not tell us how big the effect is in living humans or how it changes feelings or behavior.

Key facts:

• The study tested naturally occurring fatty acid glycerol esters along with the natural cannabinoid 2-arachidonoyl-glycerol (2-AG) in laboratory systems.
• Some glycerol esters were inactive when tested alone, meaning they did not produce a cannabinoid effect by themselves.
• When those inactive glycerol esters were present together with 2-AG, they increased the cannabinoid activity of 2-AG in the lab tests.
• The authors described this interaction as an 'entourage effect'—that is, inactive nearby molecules can change how a signaling molecule works.
• These experiments were done in controlled lab preparations, not in people, so we cannot assume the size or exact consequences of this effect in humans.
