Dr. Lynn explains why breath – where THC stays for just 2-3 hours after smoking – is the best way to measure recent marijuana use.

“Since blood tests don’t tell how long THC has been in a person’s system, [Dr. Lynn] is helping develop a marijuana breathalyzer test.” -Read Full Article

“Mass spectrometry has been the gold standard for making laboratory measurements on breath samples because of the tool’s extreme sensitivity. But, because mass spectrometry devices are large, expensive instruments – table-top or even larger – they’re not practical to take into the field. That’s why, Heanue says, Hound Labs developed a technique that is portable…

Part of the circuit involved a simulated cyclist popping out of nowhere, as cyclists sometimes do, and, Lynn reported, “all of them hit that cyclist when they were stoned, and most of the time, they didn’t even know they’d hit him.” -Read Full Article

Both [blood and urine] can provide evidence that you’ve been using marijuana — so if possession or use is illegal, then the police might have a case. But if you’re in one of the 29 states that, along with Washington D.C., allow some of kind of pot use, then it’s impairment while driving they’re after….

The company will also target employers wanting to use the device to measure whether workers are impaired on the job instead of whether employees may have smoked (legally) days or weeks earlier but are not impaired at work. -Read Full Article

Con este nuevo e innovador invento los departamentos de policía tendrán en sus manos una nueva herramienta para detectar cuando una persona esté realmente bajo la influencia de la droga. -Read Full Article

“No one wants drivers detained or wrongfully arrested because residual THC was detected days or even weeks after use. That’s the fundamental flaw of current detection methods that rely on tests of bodily fluids such as saliva, blood, and urine – methods that cannot isolate recent use because they detect THC long after the window…

Testing breath is the only way to determine recent marijuana use, and to correlate the resulting measurement with impairment. Hound Labs CEO, Dr. Mike Lynn, explains why this is crucial for both safety and fairness.
