[Edit: I thought this was so hilarious, that I had to double post]Original Post: http://dkn255hz262ypmii.onion/index.php?topic=11731.30;topicseen--I came across some most amusing information while doing my research. 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. :P
