Is it legal to fly with cannabis? Technically no, airports and airplanes are governed by federal law in which cannabis is illegal. However, TSA has gone on record saying they do not search for cannabis, they are looking for potential threats (i.e. bombs) If they do happen to find something, they are required by law to notify the authorities. So, don’t make your cannabis look like a bomb and yew should be good to go. Avoid disguising it mixed in with powder or liquids. It is important to note the unfair scanning procedures that Black, Latin and Indigenous people often face from the TSA.
