YES.     While travel within the state of Florida is allowed, despite widespread belief to the contrary, customers cannot travel from Florida to other states with medical marijuana. Anytime you go outside Florida with cannabis, whether by plane, train, bicycle, or walking, you’re transporting a federally restricted substance across state lines. Although the Transportation Security Administration does not routinely focus on marijuana screening, it will likely be confiscated if found during a search with the matter being referred to law enforcement. Many airlines and airports do not allow cannabis. Travel to other countries is also a risky gray zone; for example, Japan has a zero-tolerance policy for marijuana with even small amounts possibly landing you at least five years in jail. We recommend researching your destination for marijuana use before you travel and arrange to purchase it there, if possible.
