State Senate President Robert Stivers suggested Monday night that he might be willing to approve medical marijuana in Kentucky on a very limited basis, but he expressed skepticism about the drug's effectiveness for pain relief. Stivers stated that he is working with others to find a way to provide care for those who are at the end of their lives. He also acknowledged the lack of scientific research and cited a study that found that 67% of the relief from pain reported by patients who used cannabis was also seen among those who received a placebo, suggesting that the pain reduction may be due to expectation rather than the compounds in cannabis. Stivers also discussed potential regulations for a medical cannabis system, such as public disclosure of dispensary owners and monitoring of cannabis prescriptions.
