Even if you're traveling on a domestic flight, it's a very dumb move to carry cannabis. TSA does random bag checks. If it weren't for Brittany Griner being stupid enough to leave a vape pen in her luggage traveling to a totalitarian country like Russia, Paul Whelan would probably have never gotten out of prison. He should be very grateful for her stupidity. Now Russia gets Merchant if Death Viktor Bout out of prison. I'm sure he's grateful for her stupidity as well.
