Narkotester will detect marijuana in the breath

Many drivers go not only under the influence of alcohol but also drugs. How much of the first substance can easily be detected in the breath, so special testers are needed to detect the drugs. However, researchers at Washington State University are working on a special narcotest to detect marijuana like alcohol.

Breathalyzers easily determine the presence of alcohol in the body and determine its concentration. These devices perform well during driver testing, allowing you to quickly determine whether a particular drive is traveling on dual gas.

For narcotic drugs, it is much more difficult, because, as shown in the study conducted in 2012, as many as 30 percent of the cases of standard narcotics have failed. Therefore, to get 100 percent certainty you need to have a blood test. And it can not be done in field conditions, because the results are ready after a dozen or so hours.

Washington State University researchers are working on a special narcotic that works in the same way as a typical breathalyzer. By testing the breath for the presence of a THC substance that is the primary ingredient of the drug, he would be able to tell if the driver is under the influence of marijuana.
