i got caught at the airport for a super small amount of bud i didn't even know i had in my suitcase, wasn't a federal charge, just local state jurisdiction..
There has not been a single vacation in the last 5 years I have not brought some form of medication on. Recently on the way back I opened my goody box of cookies and my seat-mates immediately commented that someone was smoking weed. Caramels work the best in my experience.
ive done it with cookies multiple times, always brought in my carry on, never had a problem, ever, even eating them on the plane to vegas...i brought a bunch with me, at least 20 cookies all in a plastic bag in my carry on, no sweat
