With Governor John Kasich’s Wednesday approval of a law legalizing medical marijuana in Ohio, exactly half the states in the union (plus Washington, D.C.) permit the use of cannabis in some form.
Because the federal government’s official policy on cannabis use still states that it is a crime to buy, sell or use marijuana under any circumstance, individual state government policies form a patchwork quilt of different restrictions and requirements without much overall guidance.
In Colorado, for instance, it is perfectly legal to use marijuana products recreationally. But in Wisconsin, the only legal cannabis product is cannabidiol, an oil extract used to treat children with severe epilepsy. In Washington, D.C., it is legal to buy, grow and use marijuana but not to sell it.
Starting in September, Ohioans will have access to medical marijuana — but what does “medical marijuana” even mean? Who can get it, and what conditions can it be used to treat? Those answers, too, are different from state to state.
The bill Kasich signed Wednesday allows physicians to prescribe cannabis products as treatment for 21 different medical conditions, including AIDS, epilepsy, chronic pain and post-traumatic stress disorder.
This policy approves cannabis treatment for a broader range of conditions than many other states, but comes with a few caveats: the products in question must be oils, patches or edibles, marijuana will not be covered by insurance and local governments can still decide to ban or limit marijuana dispensaries.
By contrast, Illinois, which has one of the most expansive medical marijuana policies in the country, allows physicians to prescribe cannabis products for nearly 40 conditions, and these products can be smoked, eaten, vaporized or applied to the skin as a balm.
