Airport Metal Detectors
Airport Metal Detectors
Metal Detector tech hasn't changed in the last few years has it? In other words, airport metal detectors (the ones you pass through not the x-ray machines) still only detect metal correct? It wouldn't pick up say a few grams of hash, would it? 
50 characters? Nothing to say in 50 characters.
The metal detector is not an issue. In a few months though some American airports will be installing "sniffers". A sniffer is a machine what you would walk through and sample the molecules on you by sucking them off you. The sniffer is supposed to be for detecting explosives but I can imagine that they could be used to sniff other things. FYI
