San Diego, CA – On St. Patrick’s Day, California’s southernmost metropolis decided to debut a roadside test for those suspected of driving under the influence of cannabis. Several “sobriety checkpoints” were set up throughout the city with the standard invasions of privacy, but this time they added a mouth swab test known as the Drager 5000.
If a cop suspects a driver of being high, they request that he or she take the mouth swab test, and perhaps a field sobriety test as well. They’re trying to gather evidence to incriminate you, although the mouth swab test is not mandatory.
The Drager 5000, already in use in other countries and cities such as Los Angeles and New York, detects the presence of various substances, including THC, the psychoactive ingredient in cannabis. The problem is, this test has absolutely zero ability to test actual impairment or level of intoxication.
