good info and mexico is by far less strict on any pharmacy guidlines, in fact what guidelines. the metal detectors will not go off on bottles , redijects, or even pins, my guess is that so many people carry across legal drugs,and wear metal on their shirts,belts,pants etc. they would be stopping nearly everybody,i just wouldnt want to carry across that nice looking set of brass knuckles that jose wants to sell you for 2 bucks.
