These receptors are ordinarily activated by chemicals similar to THC that naturally occur in the body (such as anandamide; see picture, above) and are part of a neural communication network called the endocannabinoid system. This system plays an important role in normal brain development and function. However, THC-based drugs to treat pain and nausea are already FDA approved and prescribed, and scientists continue to investigate the medicinal properties of other chemicals found in the cannabis plant—such as cannabidiol, a non-psychoactive cannabinoid compound that is being studied for its effects at treating pain, pediatric epilepsy, and other disorders.
