Cocaine Use Can Now Be Tested In Fingerprints Using Ambient Mass Spectrometry

hypnosec writes: A novel technique of detecting cocaine abuse through a simple fingerprint has been developed by researchers from the UK and the Netherlands, paving the way for a secure, non-invasive drug detection method. The research, led by University of Surrey and published in the journal Analyst, demonstrates for the first time that cocaine can be detected by the excreted metabolites – benzoylecgonine and methylecgonine – resulting from abuse of the drug. These chemicals are found in fingerprint residue, which the researchers detect using analytical chemistry technique known as ambient mass spectrometry.

    lets spend billions upon billions to stop people from doing things to themselves, not even taking the 4th amendment into consideration

    Im not condoning abuse, but im also not condoning the absurd spending that we as a planet have done "for the children"

      You just don't understand. This is the breakthrough we've been looking for to finally win this war on drugs.

      It's only a matter of time now before 'Drugs' throws up the white flag.

      Your comment is highly misleading; with very few exceptions the police can't test you for drug metabolites without a warrant. Implied consent laws for driving and people on probation are the two scenarios that are most common. In the case of the former they may well need a court order, depending on the State. In NYS they can't ask for such an order unless you're involved in an accident involving personal injury. Mundane DWI and you refuse the chemical test? They can't do a damn thing about it. Run someone over and refuse the chemical test? They're gonna get a warrant and hold you down to draw blood.

      Either way, the cops aren't using drug testing to conduct fishing expeditions. It costs too much money for that. That CSI nonsense where they use DNA and mass spectrometry to figure out who threw the litter on the side of the highway? Doesn't happen in the real world. In the real world law enforcement agencies have finite budgets and testing for drugs, DNA, or even dusting for prints costs money.

    ...cocaine can be detected by the excreted metabolites...resulting from abuse of the drug.

    What about those that don't abuse cocaine, but use it responsibly?

    The metabolites are stable for a long time. They can transfer from paper money to your oil/sweat-laden fingerprints.

    And it's usually $1s and $5s that test positive for cocaine metabolites, and cocaine itself.

    The abuse of civil forfeiture is well documented; but this test isn't really relevant. If they intend to abuse civil forfeiture to take your stuff, this test isn't going to be their go-to.

    And if they don't intend to abuse civil forfeiture, all this test does is establish evidence that you've taken cocaine.

    If drug use is detected

    They need evidence of drug related crimes. Technically, past drug *use* isn't even illegal.

    Yeah but for some schizophrenic reason they still call it the "land of the free". "Denial" isn't just a river in Egypt you know.

    Oh yeah and from the summary, this is ridiculous.

    Yeah there's nothing invasive whatsoever about having your unique fingerprint on file, never to be deleted, and linked to the results of a drug test with an unspecified fase-positive rate and no appeals process. Really? The War on (some) Drugs is bullshit to begin with, and the fact that it provides so many excuses for shit like this is just one of many reasons to end it (other reasons being the freedom of consenting adults, and a notion of justice with this being a victimless crime).

    Anybody who wants drugs can get them. They cannot even keep drugs out of PRISON. That's just a fact, even though the prison environment strongly favors the people trying to prohibit drugs. Oh and it's easier for teenagers to get illegal drugs than it is for them to get alcohol since drug dealers don't ask for ID. The War on (some non-patentable, not pushed by Big Pharma) Drugs is a failure. It's past time to stop this futile effort and move on to something that might work, such as regulated legal sales to adults. It only took about a decade for people to realize that alcohol prohibition was not going to work. Sure, the intelligent freethinkers knew that before it was made law, but listening to them is not popular. It's been close to a century since we tried prohibition of other drugs and it's a failure. It amazes me the way people will continue to support failing ideas in the face of all evidence to the contrary. Must be a religious deal?

    For drug dealers, perhaps the status quo. But for drug users, perhaps we should focus on reform and helping them. Treat it as a sickness and not necessarily as a crime.

    I'd be worried about false positives with this test.

    General skills, aka the ability to succeed in society without reverting to drug abuse, are considered when a company is hiring.

    Chemcial tests can't tell whether a person is absuing drugs, only if they are using them. (It is a prohibitionist fiction that the use of certain drugs is inherently abuse.)

    If the only way you can tell whether someone is using drugs is through chemical tests, ipso facto it is not affecting their performance on the job.
