I am prescribed xanax and I put it in a little pill carrier so I can take it when I want without having to carry the bottle. I have gone through airports and even had police ask what it was. I just tell them the truth and they have never tried to arrest me for not having it in the original bottle. I would assume if I had 1000 of them in some container that would probably be a red flag, but something obviously in quantity for personal use is no biggie. On the two occations I had a cop ask about the pills once they found out what they were they would make remarks like "lucky you"...etc...but never anything bad.
