Am I legal in Florida if I have an out of state card?

NO.     Currently, Florida does not have MMID reciprocity with other states. Having a license in any other state with a medical marijuana program does not qualify you in Florida. To obtain your cannabis card within this state, and be able to purchase cannabis from a Medical Marijuana Treatment Center, you need to be evaluated by a certified Florida marijuana physician, who can register you onto the Florida State Medical Marijuana Use Registry.
