If driving high is part of your normal routine, it might be wise to be more cautious now that more states are legalizing marijuana and law enforcement is stepping up efforts to curb stoned driving.
States such as Colorado are now ramping up efforts to nab drugged drivers with their recent statewide marijuana testing program, which allows them to use weed breathalyzers to detect cannabis in the driver’s system. The program also calls for using five different breathalyzers since the state is still testing each method but with various results. The results could potentially be inaccurate or take time and could arrest individuals who are not high but a new method to test for cannabis in a person’s system has been developed that will test for THC in 3 minutes.
The system was created by Professor Shan Xiang Wang at Stanford University and is a saliva-based test that uses a magneto-nanosensor able to detect traces of marijuana in saliva as rapidly as three minutes. The sensors require connections via Bluetooth to a smartphone where officers can analyze instantly eliminating the need to test at a lab.
