People often ask, “Does being high impair driving?” The Tennessee Bureau of Investigation does test for certain substances in blood including marijuana, and alcohol, and other types of drugs. The test that they typically do for marijuana only measures the metabolite. What that means is they’re only measuring to prove that you have actually had something to smoke typically in the last 30 days. It makes it very difficult for the state to prove beyond a reasonable doubt that somebody is impaired by marijuana because metabolite doesn’t tell us anything usually other than someone has had something to smoke in the last 30 days or so, Evidence that you smoked marijuana 30 days ago doesn’t tell us anything about whether a person is impaired or uinimpaired at the time they drove.
