A coalition of medical groups, including several that opposed the ballot question that legalized medical marijuana in Oklahoma, says the law needs at least three fixes to protect public health.

At a joint press conference on Monday afternoon, the group called for three rules on dispensaries: requiring them to have a pharmacist on staff, limiting the number of licenses available to open one and forbidding them to sell smokeable forms of marijuana. Patients who grow marijuana for their own medical use would still be permitted to smoke it.

The Oklahoma State Department of Health is scheduled to vote Tuesday morning on a set of regulations that doesn’t include the medical groups’ three priorities, and it isn’t clear if the board might consider the proposals in the future. Dr. Jean Hausheer, president of the Oklahoma State Medical Association, said coalition members have met with interim Health Commissioner Tom Bates and members of the board, but the Health Department raised legal concerns about some of their priorities.

The ban on products that can be smoked is intended to ensure patients get a consistent dose of the active chemicals in marijuana, without the negative health effects of inhaling combusted material, Hausheer said.
