All animals may benefit from cannabis, like hemp, where THC is limited. In the 1990’s scientists discovered Endocannabinoid, the natural cannabis-like molecules produced by the human body. They seem to maintain “biological harmony.” The scientists discovered that they evolved over 500 million years ago. It is present in all vertebrates, mammals, birds, reptiles, amphibians, and fish. All of them produce Endocannabinoids.
