Terminally ill patients will be allowed to use full-strength medical marijuana under a bill passed Monday that would expand the drug’s use in Florida.

HB 307 expands existing law that allows patients with seizure disorders, such as intractable epilepsy, and cancer to have access to a non-euphoric strain of cannabis.

It also solidifies a system that could give growers who already have licenses a head start on an even larger market if a proposed constitutional amendment passes in November’s election. That amendment, which appears to have broad public support, would further expand the ailments eligible for medical marijuana.

The Senate passed HB 307 on a bipartisan 28-11 vote and sent it to Gov. Rick Scott for his signature or veto. A spokeswoman for the governor said his office is reviewing the legislation.

Patients were supposed to have access to the non-euphoric cannabis more than a year ago, but legal fights between competing interests who have been excluded from licenses caused delays — a system Sen. Don Gaetz, R-Niceville, called “the swampland of greed and money.”
