Chemical compounds called cannabinoids are found in marijuana and also are produced naturally in the body from omega-3 fatty acids. A well-known cannabinoid in marijuana, tetrahydrocannabinol, is responsible for some of its euphoric effects, but it also has anti-inflammatory benefits. A new study in animal tissue reveals the cascade of chemical reactions that convert omega-3 fatty acids into cannabinoids that have anti-inflammatory benefits—but without the psychotropic high.

The findings are published in the Proceedings of the National Academy of Sciences.

Foods such as meat, eggs, fish and nuts contain omega-3 and omega-6 fatty acids, which the body converts into…
