A roadside breath test for marijuana is in the works according to a recent article in the High Times. The device, similar in construct to the portable device that tests for alcohol (PBT), was developed by a retired Canadian drug enforcement agent who believes the fear of prosecution for DUI is what deters most drivers from driving after consuming alcohol or drugs. Critics of the Cannabix Breathalyzer believe the device may lack accuracy and reliability and incriminate some drivers who are not necessarily impaired. Researchers will continue to test the device for accuracy and perhaps develop new field sobriety tests to be used in conjunction with the Cannabix device. Whether the device will be used in the US will likely depend on its ease of use and degree of reliability. Read the full article here.
