Sen. Dana Young is pressing the Department of Health to ramp up efforts to issue more licenses for medical marijuana providers.

Young, a Tampa Republican, sent a letter to Office of Medical Marijuana Use director Christian Bax on Tuesday.

She referred to the state’s cracking the 100,000 mark last Friday – coincidentally on April 20, or 4/20 – in the number of registered medicinal cannabis patients.

Lawmakers, as well as patient and provider advocates, have been complaining about Florida’s supply of medicinal cannabis not keeping up with what they say is the burgeoning demand.

“Given the indisputable fact that patient demand for medical marijuana is quickly increasing, my strong recommendation is that the Department award the additional four contingent MMTC (medical marijuana treatment centers) licenses in the upcoming review cycle to be activated once the number of qualified patients reaches 200,000,” Young wrote.

Approved MMTCs currently number 13, with 34 retail locations across the state, state records show.

“Thus, the review for issuance of licenses for the 200,000 patient threshold would be done at the same time as the review for licenses to meet the initial 100,000 threshold,” Young said.

She added: “Based on information from my constituents and others interested in the success of Florida’s medical marijuana program, there are many interested and qualified applicants for these statutorily mandated additional MMTC licenses, ensuring that the current application cycle will have a sufficient number of strong candidates.”

Surterra also is licensed in Florida, with six dispensaries here. Young faces re-election this November against outgoing Democratic House Leader Janet Cruz, also of Tampa. Democrat Bob Buesing has said he’s dropping out of the race.)

But a Health Department spokesman last week noted that patients
