The SensAbues DrugTrap is out to foil your drugged-up driving experiences.
The breathalyzer. Anyone pulled over on suspicion of driving under the influence knows it all too well. Since the 1980s, police have used the tool, first developed in 1967, to detect alcohol content in the blood. Until now, breath samples have only really been accurate in terms of alcohol, but Swedish researchers have just published a study which touts the abilities of the new product, a breathalyzer for drugs.
The product and research comes from Stockholm’s Karolinska Institute, who used their drug-detecting breathalyzer to detect the presence of a wide variety of illegal drugs - with accuracy. They were even able to detect a host of other drugs with a little less accuracy.
Researchers tapped 47 participants from the Stockholm Drug Emergency Clinic, collected blood and urine samples (for comparison), and had them blow into their device. Researchers say that they were able to accurately detect these substances: amphetamine, methamphetamine, morphine, heroin, THC, Diazepam, Oxazepam, cocaine, and benzoylecgonine.
And with less accuracy, these: Codiene, MDMA, Methadone, Nicotine, Continine, Zolpiden, and MDPV (bath salts)
Here's how SensAbues describes the technology:
During normal breathing microparticles are formed from the airway liquid fluid by the closure and opening of bronchioles. These particles form a bioaserol that is carried out in the exhaled breath. These bioaerosol particles can be selectively collected by a unique filter technique developed at the Karolinska Institute. Collected particles can be used for drugs of abuse detection by analysis with high sensitivity technique, e.g. liquid chromatography – mass spectrometry.
"Until now, sampling for drug testing has been a complicated, lengthy or intrusive process: urine samples have to be collected under surveillance; blood tests that have to be taken by trained medical staff. SensAbues offers a sampling device for easy and rapid sampling on site, a sampling procedure difficult to adulterate, and analysis by mass spectrometry for legally defensible results," says SensAbues.
It could be only a matter of time until police everywhere are able to quickly and easily breathalyze you for anything. Yeah, science?
