The possibility of taking edibles on a plane depends not only on what type of edible you have but also on where you plan to fly from and where to. Products with THC in them could be prohibited to transport from one state or country to another, even if cannabis is legal both at the point of departure and at the destination. In case of air transportation within the U.S., the federal law might still be applied at the airport and while traveling across states. The airport security will refer any suspected illegal substance to the police.

CBD products might be regulated differently, but it is always better to check whether the product has some THC and what are the legal requirements regarding its transportation to the destination. Also, you can get additional restrictions from airlines.

When trying to find out "Can I take edibles on a plane?", the most reliable step would be checking TSA recommendations, airline policies, and laws in force at the destinations you plan to fly to and from. While traveling internationally, don't expect that any product which is legal in your home state is legal abroad.
