how to bring edibles on a plane Since edibles are still frequently regarded as controlled substances in many nations, it is illegal to bring them on aeroplanes. If you try to carry edibles on a plane, you could face serious legal repercussions, such as being arrested and charged. If you need to bring medical marijuana or other prescription medications on your trip, keep them in their original containers with the prescription label still attached. Along with any other pertinent documentation, you should carry a letter from your doctor outlining the reasons you require the medication. To make sure you are aware of any limits or requirements, it is usually better to check with the airline and the TSA (Transportation Security Administration) before travelling.
