An old stoner friend of mine told me a long time ago to ALWAYS keep weed on your person and not in a back pack, in your car etc. He said itâ??s always a little harder for cops to search you than your stuff, etc.

So using that philosophy I would say you are a lot better off keeping in your pocket or taped to your clothes like you said NOT in your luggage.

My 2 cents.

P.S. You also could cosider just mailing it to yourself in STL before you leave. Then you dont have to have it at the airport at all.
