gj87 -- I agree! I want to be legal! It's not a secret! But nobody knows anything. I only called the TSA because the DEA (6 DEA agents) were not sure. One told me to call DHS, which told me to call TSA. Crazy!
But now I have numbers for CBP -- you must call individual air ports because CBP main number doesn't answer. It's funny, I called one CPB port and the person yelled at me "how did you get this number!".
Maybe I'll call later, but I think I will stop. Without the medicine it will be harder, but not hard as jail.
I think if a country wants the laws like that, it should make them clear. If US government agent does not know the law, how can other people know?
