It is the cannabinoids in cannabis that effect people. Scientists have discovered an “endocannabinoid” system in human beings. It is this system that processes and is affected by cannabis in the body. Some medical studies report that it is this system that can protect the nervous system, strengthen the immune system, and play a positive role in ‘stress recovery’. These functions are regulated by cannabinoid receptors binding to the endocannabinoids.
Most people are familiar with THC and CBD, but cannabis actually has many cannabinoids, each of which have different healing properties that effect the body in different ways. THC is what makes most cannabis consumers feel “high,” hitting the brain and body. CBD by contrast will not make the user feel high or impaired. It has even been said that higher doses of CBD helps “lower some of the effects” of THC in the user.
