I think it's some comfort to our professional vendors dealing in high volumes.- A 2009 study showed that at least 90% of US dollar bills have cocaine residues on them, and some of the tests showed that more than 95% of the cash in circulation is cocaine- contaminated.- People send cash through the post all the time despite being told it's a stupid idea by the postal service. Especially at Christmas time.Putting two and two together, this will mean:Using electronic noses for drug detection systems to stop each and every package is actually impossible.Yes, you can use a electronic nose for drug residue detection.Yes, in theory they are able to detect up to 1 billionth of a gram of cocaine or other drug.But in practice probably more people send cash through the post in the world, than use SR's services (those statistics don't differ much between Europe and America). As a result, the sensitivity of the electronic drug detection mechanisms has to be quite low or they would have to stop the mail every couple of seconds.Obviously this doesn't mean you should stop vacuum packing and using rubbing alcohol to get rid of drug residues, but it certainly makes sure that LEO is put back in his box. :PI doubt dogs can smell 0.0000000000000000000000000000000000000000001 gram of cocaine on a bill. Otherwise every time I get pulled over and a dog sniffs me he would bark at my bills.Woe betide you, you doubting Thomas! Actually it is not so simple as that, let me explain more fully.The Hound 2 System in prison mailrooms can detect up to 1 billionth of a gram of drug residue. Google away and check it out.That is 0.000000001 of a gram.Even the fundamental particles in physics are bigger than 0.0000000000000000000000000000000000000000001 of gram, so let's keep a sense of proportion here! God! :PAs for man's best friend, I'm willing to bet he is actually better than the machine, not worse. Not in terms of quantity per say, but in terms of accuracy. The reasons are simple:A: Dogs are hunters. Hence they have finely tuned biological filters for what is significant and what is not significant (mostly nose).B: Dogs have been hunters for hundreds of thousands of years of evolution.C: Dogs have been hunting with humans for at least tens of thousands of years of evolution.D: There is a big difference between being able to *detect* some quantity, and *knowing* if it's relevant to the situation.Dogs really are smart enough to do (D), and the combination of being addicted to the drug + desire to please their human masters is exceptionally powerful motivation.I bet my bottom dollar on the Dog, over the Machine, any day of the week. It's like comparing a pop gun with a atom bomb.Respect the Dog, he is your best friend and enemy, so don't underestimate him. Viktor Suvorov (a defector) says one of the first things the GRU (Russian Secret Military Intelligence Agency) teaches its operators is to respect the Dog. They think this lesson is so important, they release their agents into the wild and then hunt them down with dogs.
