Cocaine Use Can Now Be Tested In Fingerprints Using Ambient Mass Spectrometry 143

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.

      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.

      The 4th amendment regulates the behavior of Government. It has nothing whatsoever to do with your relationship with a private employer. Drug testing is a crock of shit for a lot of reasons but the 4th Amendment is not one of them.

      • Yes, this will be used by private employers. However, it will also be abused by the police until a supreme court decision comes out of it one way or the other.

          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 som

            1- While a dragnet search might be impractical, an individual can still be targeted. For example: a corrupt authority has a cocaine-using informant hold a glass, which is then given to their target in a restaurant and taken as evidence afterwards. Bam, their target is on coke, liable for some of the most egregious penalities in our legal system.

              I didn't say we should rely on it; I simply stated that's how it works in the real world.

              Hypothetical Anecdote: I threw a McDonald's cup out of my car of my today. My fingerprints are in the system. I have no expectation of privacy with something that I willingly discarded. Fingerprint dusting and testing is comparatively cheap, thanks to advancements in technology. Is there going to be a knock on my door in a few days? Not bloody likely.

              Drug testing costs significantly more than fingerprint dusting

              Bam, their target is on coke, liable for some of the most egregious penalities in our legal system.

              Incidentally, it's not illegal to have drug metabolites in your system. It's not even illegal to use drugs. It's illegal to possess them, in certain jurisdictions, but unless you're on probation or hold certain licenses (a CDL or firearms license) the legal consequences of a positive drug test are non-existent. There may be private consequences, like termination of employment, but you don't go to jail for a positive drug test.

                If you took the drugs, then it's proof that you were in position of the drug at one point.
                • Its not proof that you were knowingly in possession of them. I believe that is the standards to meet too. For instance, i could slip something into your drink or food or have residue on something you are supposed to handle (money, car seat, whatever).

                  Testing positive is proof of nothing other than you tested positive for some reason.

                • If someone lays out a couple of lines of coke and someone else snorts them, was the person snorting the coke in possession of it?
            • Keep in mind that your targeted individual can't be tested without a warrant, no matter what the coke-using informant does to the cup. They could probably get a warrant if the coke-using informant says the target is a junkie, but the test isn't actually proof of anything illegal (remember: using drugs is technically legal, it's possessing them before you've taken them that's the problem). They might be able to use to get a warrant for the target's house, and plant some drugs or something in the toilet; but

                If you think this is only going to be used with warrants you sure haven't been paying attention. Maybe, if we are lucky, in 10 or 15 years the US Supreme Court would set up sensible rules about warrant requirements for fingerprints, but I sure wouldn't bet on it.

                • You're getting ahead of yourself.

                  The Courts currently require warrants for this kind of testing. They may in future change their minds, and say it's an extension of non-warrant-requiring fingerprint tests, but that ruling has not happened.

                  Moreover, as I pointed out (and you completely ignored), if the cops have a coke-using informant whose willing to fake evidence against you they really truly have no need for this test. They can get their warrant, plant their evidence, and fuck you over just based on the g

            You seems to misunderstand how police budgets work. They don't have the money to go after every crime, and they especially don't have money for crimes that no one cares about (black on black crime for example), But, if you somehow catch the attention of someone higher up in the department and they think they could get a career promotion from busting you, then you better believe they have hundreds of thousands at their disposal to catch you with.

              Your link discusses what private individuals are doing, not law enforcement, so it's kind of irrelevant here.

              Regarding your red herring, cops don't get "career promotions" for busting people for drug possession. And if you're going around pissing the cops off for no particular reason you should probably take care to mind your Ps and Qs.

              Example: In New York State marijuana possession is a violation (i.e., less than a misdemeanor) punishable by no more than a $100 fine. It actually costs less than a speed

            I guarantee you someone is working a spreadsheet figuring out if they buy a bunch of high tech scanners and can get more people with positive results they can seize a lot more stuff to pay for it.

            Test positive? We'll take everything you have on you, your car and possibly your house and we can do it all now without any court approving it. You have to prove to us that it's not ill-gotten gains.

              Please give me a single citation of someone facing civil asset forfeiture for a positive drug test. Just one.

              The authorities can't compel drug testing, outside of the few exceptions (suspected drugged driving, probation, or CDL holders), so how exactly are they going to use it as a basis for asset forfeiture?

                I can't, but I can give you plenty of citations of civil asset forfeiture for even less illegal activity -- like driving on the highway and having a large amount of cash or just making a wrong turn. Many areas have been extremely aggressive to the point of insanity with civil forfeiture.

                Existing drug tests now require more extensive court orders, but if you have basically a fingerprint scanner which can provide prima facie evidence of involvement in the cocaine business it's naive to believe this won't be

  • Note that this method does NOT work with a printed copy of the fingerprint, only the original fingerprint itself. That is because it detects chemicals which are sweated out onto the skin. and when the finger is pressed to the paper, the sweat is pressed onto the paper. The cocaine does NOT change the shape of the swirls; it only adds invisible chemicals to the sweat and ink on the paper.

This test sounds like it uses much smaller samples so I would imagine it would be far more susceptible.
