How Michigan’s oral swab test could change drug-impaired driving enforcement

A proposed bill in Michigan seeks to implement oral swab drug testing to reduce impaired driving, with backing from law enforcement. The bipartisan bill, introduced by House Representative Brian BeGole, aims to test for substances such as cannabis, cocaine, heroin, and certain prescription drugs. While it's praised for being non-invasive and reliable, concerns exist over potential false positives, particularly for cannabis. The bill has advanced to the Senate for further consideration amid debates on balancing public safety and scientific validity.
