State lawmakers want to keep Florida pot home-grown. But the low-THC medical marijuana recently authorized by the Legislature has sparked an out-of-state “green” rush before the bill has even been signed into law.

Pot-related business owners from outside the state are less interested in the low-THC strain that will soon be legal—Gov. Rick Scott has said he will sign the bill—than the regular old weed, if only for limited medical use, that might be authorized by voters in November.
