This summer, Missouri Governor Jay Nixon signed a bill that legalized some medical uses of cannabidiol (CBD) and some growing of marijuana in order to produce that oil. However, the new law still leaves most medical marijuana use and all recreational use prohibited in the state. CBD is an oil that can be extracted from the leaves of marijuana plants. Medical researchers say that CBD is not psychoactive. While formal evidence of the medical efficacy of CBD is still scant, families across the United States and in Missouri insist that CBD has been effective in reducing seizure activity in severe epileptics. The new law in Missouri will restrict usage of CBD to chronic epilepsy patients for whom three or more traditional treatments have failed. This means that in Missouri, patients with other serious illnesses, including cancer and HIV/AIDS, will still not be allowed to use cannabis. Facilities created to grow the plants will be licensed and regulated by the state. Earlier this year, the passage of Missouri Senate Bill 491 revised criminal penalties for illegal possession of marijuana, removing the possibility of jail time for first-time offenders possessing a small amount of the drug. However, most of Missouri’s harsh penalties for marijuana possession remain in effect, especially for major possession and repeat offenses. Moreover, the revised law does not go into effect until January 2017.
