Philips Develops Roadside Drug-Testing Device
Al writes "A handheld developed by Philips for law enforcement detects traces of cocaine, heroin, cannabis, and methamphetamine in 90 seconds. The system uses magnetic nanoparticles attached to ligands that bind to traces of these drugs. Once saliva has been placed inside the device, an electromagnet mixes the sample and the nanoparticles. Frustrated total internal reflection (FTIR) — the same phenomenon that underlies fingerprint scanners and multitouch screens — is then used to measure a change to the refractive index. By immobilizing different drug molecules on different parts of a sensor surface, the analyzer is able to identify traces of each different drug. An electronic screen displays instructions and a simple color-coded readout of the results."
This could go a long way towards treating other drugs like alcohol for driving purposes. One of the major roadblocks in legalization was no field test for driving while impaired.
Can this tell the difference between intoxication and merely having used said drug in the past couple of days? While cannabis may be illegal, a DUI should not be warranted if you happen to test positive, given the long time it's present in your bloodstream.

There has been some news here in the Netherlands about it and no it can't see whether you are under the influence or have used it in the last 24 hours or even days before depending on the drug. Most drug effect wear off after sleep and this machine won't know the difference. In the Netherlands this is such a big problem that drug prevention units like Trimbos are advising against its use as it will create more problems than solve. But maybe it works better in countries that prosecute users anyway.
I knew a guy in college who could smell weed from miles away. No matter where you were, if you broke out a joint, he would magically show up within minutes. Hiring guys like that has to be cheaper than these devices.
... so our government can keep being at 'war' with us.
Drugs are a social health problem, not a criminal problem. Sadly our representatives and much of our populous lacks the maturity or the foresight to acknowledge this difference --- and thus the current moralist/criminalist approach leads to filled prisons and fines that leave us wondering why we're all such bad people.
Wake up -- curiosity and susceptibility are not bad things. Given the change in availability and removal of black markets, most drugs only impact the individual -- and for 'other crimes' that people may commit on drugs, those acts are still criminal. Example: in a meth legal world, the addict is not treated like a criminal, but if she neglects her child she can still be held responsible for that neglect.
Like I said, drugs are a health issue.
Police could test actual impairment. Some years back I read about an impairment testing device for use in factories and heavy machinery. It's a simple LCD screen with a left-right joystick. A dot moves randomly to the left or the right on the screen, the user tries to keep it in the center using the joystick. If their reaction times are not impaired, the device unlocks the machinery. If they are, for whatever reason, like sleep deprivation, prescription medications, illegal drugs, or whatever, then the machinery remains locked. The police could test actual impairment rather than the presence of things that might or might not impair reactions. This would catch any sort of impairment which might endanger drivers and others on the road. For instance, studies have found that people with severe sleep apnea are about as likely to get in an accident as someone with a .1 BAC. If we are trying to protect people on the roads, rather than simply punish users of certain substances, this would be a fairer option.

Its just a photo of a dog in a baseball cap and sunglasses, if you totally think he looks like he could drive a truck, you failed the test.

So much for making out with crack whores.

... letting the "war on drugs" police-prison-industrial complex beat us into the ground (i.e., take away all vestiges of privacy, personal choice, and/or any sense of pleasure) with its ever advancing technology? We should just end the WOD already? It ain't nobody's business what drugs/substances I use, drink, smoke or eat if if it doesn't harm anyone else. We need to declare an end to this Nixon era nightmare so we can empty out the prisons, give cops something more productive to do and increase our revenues by taxing the dopers to recoup what we can from their vices. Drug abuse is a medical problem not a PPI one. So let's treat it that way before the PPI's tax subsidized techno mavens create a total (but drug free!) police state for us to live. (End of rant)

Personally I'd much rather see a test for melatonin levels than any narcotic. Driving while tired is much more common and more hence likely to cause accidents than drug use I think.

You mean you weren't sure whether or not you were stoned for half the tests?
PHEM - party like it's 1997-2003!
