Medical marijuana: emerging applications for the management of neurologic disorders

Marijuana contains over 60 different types of cannabinoids, which are its medicinally active ingredients. Cannabinoids have the capacity for neuromodulation--through direct, receptor-based mechanisms--at many levels within the nervous system, providing therapeutic properties that may be applicable to the treatment of neurologic disorders. These include antioxidation, neuroprotection, analgesia, anti-inflammation, immunomodulation, modulation of glial cells, and tumor growth regulation. This article reviews the current and emerging research on the physiologic mechanisms of endogenous and exogenous cannabinoids and their applications in the management of neurologic disease.
