Meta AnalysisWhat Do You Know About Maryjane? A Systematic Review of the Current Data on the THC:CBD Ratio.
Background: Ratios of delta-9-tetrahydrocannabinol (THC) and cannabidiol (CBD) impact metabolism and therapeutic effects of cannabis. Currently, no states with legalized medical or recreational cannabis consider ratios THC:CBD in regulations. Objective: Determine what THC:CBD ratios are selected for use in clinical cannabis trials and what is the rationale. ⋯ One study compared ratios of high and low THC:CBD, but did not specify the ratios. Conclusion: The medical and scientific communities have not drawn substantive conclusions nor thoroughly explored THC:CBD ratios for "best practice" treatment of different disease processes and their sequelae. While there is evidence that cannabis provides medical benefits, research is lacking on standardization of medical cannabis use in modern medical practices.
