How do you tell if someone is high or not—but, more to the point, how do you tell if they’re too high to drive? A marijuana breathalyzer sounds nice, but the technology simply may not work, a recent study suggests.
“This contrasts with the much stronger relationship between blood alcohol concentrations and driving impairment,” according to the researchers, whose work was published in the journal Neuroscience & Biobehavioral Review—and whose findings have “implications for the application of drug-driving laws globally,” they said.
In this, police and public-safety minded lawmakers have been spoiled by alcohol breathalyzers. Breathalyzers give police a quick and accurate-enough reading of a driver’s blood-alcohol count, because biology. The human body starts to break down alcohol almost immediately, and impairment exists as long as alcohol is present. That maxim—if it’s present, it’s impairment—is how alcohol works in the body, and why alcohol breathalyzers work.
Paris on May 12, 2018. - Some 1,300 people, according to the police, marched today in Paris for the decriminalization of cannabis in France, which"remains blocked" while, for the organizers,"the other countries have never advanced so far" on this issue. To their credit, makers of marijuana breathalyzers have tried to measure cannabis impairment in other ways.
