Knox Medical is the fourth organization to receive authorization to distribute low-THC medical marijuana in the state of Florida.
Florida's Department of Health gave the Winter Garden-based organization authorization over the weekend. Knox Medical spokesman Adam Sharon says they expect to begin in-home delivery to patients by Friday.
Knox's approval is the first since Amendment 2 was passed overwhelmingly by voters last month.
The amendment broadened access to pot beyond the limited therapeutic uses approved by the state legislature two years ago.
Department of Health spokeswoman Mara Gambineri says 208 physicians and 1,150 patients are currently in the state registry for ordering and using medical marijuana.
