A group of researchers and scientists working out of Stanford University are developing a high-tech marijuana breathalyzer that is designed to be potentially used by law enforcement personnel to assess whether drivers are dangerously high on the road.
This particular marijuana breathalyzer technology works by measuring the amount of THC in saliva. It is precise enough to be able to detect THC to a level of zero to 50 nanograms per milliliter of saliva by making use of special magnetic biosensors.
This marijuana breathalyzer is an important innovation in the prevailing atmosphere where cannabis is becoming legalized in many jurisdictions. While there still needs to be a lot of research done to understand how different individual levels of tolerance impact a driver's ability to drive safely under the influence of marijuana, this marijuana breathalyzer will help law enforcement to assess situations more objectively.
