According to federal law the answer is no – you may NEVER fly on a commercial airliner with marijuana or marijuana containing products, even if you have a doctor’s written recommendation for medical marijuana or a medical marijuana card. It does not matter if you are flying within state, out of state or out of the country, the answer is always no. You may be fined and or detained for flying with marijuana.
It’s illegal to take marijuana through a TSA checkpoint, so technically, no, though various Internet users report little risk if the amount you carry in your luggage is small and for personal use. Still, it isn’t advisable. If you’re planning on traveling ib a private plane, the rules may be different, but it is illegal to carry marijuana past a TSA checkpoint.
No, you cannot fly anywhere with marijuana. Commercial airports and airlines are under Federal jurisdiction. Marijuana remains illegal under Federal law and the TSA does not respect local law. Where you are flying does not matter as the marijuana becomes illegal as soon as you enter a commercial airport. The TSA may just warn you, but they also could prosecute you.
