People asked me the same thing going to an airport. They’ll say hey I have a medical marijuana card and I’m flying going to Colorado where I can buy there recreationally. The problem is once you get into that federal jurisdiction the federal law is going to hold. So, if you go into an airport, if you go into a federal building those federal officers are not going to care that you have a Florida medical marijuana card. They’re going to say hey it’s illegal under the federal system and they can still prosecute you for it.
