Trying to come up with regulations for the state's new medical-marijuana industry, the Florida Department of Health will host two days of meetings in February to try to hammer out a plan with interested parties.

The department announced Monday that it will hold a "negotiated rulemaking" meeting Feb. 4 and Feb. 5 in Tallahassee. In publishing a notice of the meeting, the department specified representatives of groups it wants involved.

They include representatives from a nursery, a testing laboratory and the Department of Health. Also, they include a patient or patient representative, an attorney experienced in administrative law, a person with experience in agricultural practices and regulation, a physician authorized to order certain types of medical marijuana for patients and a person experienced with regulation of cannabis products elsewhere.

Under a law passed last year, doctors on Jan. 1 were supposed to begin ordering strains of cannabis that are low in euphoria-inducing tetrahydrocannabinol, or THC, and high in cannabadiol, or CBD , for patients who suffer from severe spasms or cancer.

But after a legal challenge from a group of nurseries and other businesses, an administrative law judge in November struck down the health department's first proposal for a regulatory structure.

That has prompted the department to make another attempt at drawing up a rule.
