Abstract:

Growing basic research in recent years led to the discovery of the endocannabinoid system with a central role in neurobiology . New evidence suggests a therapeutic potential of cannabinoids in cancer chemotherapy - induced nausea and vomiting as well as in pain , spasticity and other symptoms in multiple sclerosis and movement disorders . Results of large randomized clinical trials of oral and sublingual _Cannabis_ extracts will be known soon and there will be definitive answers to whether _Cannabis_ has any therapeutic potential . Although the immediate future may lie in plant - based medicines , new targets for cannabinoid therapy focuses on the development of endocannabinoid degradation inhibitors which may offer site selectivity not afforded by cannabinoid receptor agonists .
