In the United States, the Controlled Substances Act (CSA) of 1990 classifies marijuana as a Schedule I substance, which states it has no approved medical use and a high potential for abuse.According to the National Institute on Drug Abuse (NIDA), marijuana is the most abused drug in the US.Many states in the US have now legalized marijuana for medical or recreational use.Sativex is composed of standardized extracts of THC and cannabidiol and is available as an oral mucosal spray formulation.Studies from Lakhan, et al report that THC and cannabidiol (CBD) provide therapeutic benefit for Multiple Sclerosis (MS) spasticity (muscle stiffness/spasm) symptoms.GW Pharmaceuticals and Otsuka Pharmaceuticals announced results of three US Phase 3 trials in 2015 for the use of Sativex for the treatment of pain in patients with advanced cancer who experience inadequate analgesia during optimized chronic opioid therapy.
According to the study results, Sativex did not meet the primary endpoint of demonstrating a statistically significant difference from placebo for pain control.
