A commission commissioned by the state of Michigan has asked not to set a THC limit for drivers.
The Departmental Road Safety Commission, appointed by former Governor Rick Snyder, is a six-member committee to scientifically study the effects of THC on driving. The panel included a patient who used cannabis for medical purposes as well as experts in law enforcement, forensic toxicology, cannabis pharmacology and road safety. The commission studied pre-existing research on the relationship between cannabis and driving and conducted its own road fluid testing in collaboration with the Michigan State Police.
The result of rapport revealed that there is a low correlation between THC body content and impaired driving. In particular, the report mentions that because of the rapid elimination of THC body content, THC levels can be considerably lower at the time of a blood test, which greatly underestimates the amount of THC in the body. when the person was driving.
The report also suggests that the "Zero Tolerance Policy" in the state of Michigan, assuming there is an alteration in the detection, ≥1ng / ml, could falsely conclude that a person is impaired " .
La commission also notes that frequent cannabis users require a much higher THC body content to achieve the desired effect. In other words, a state-imposed limit for driving with THC may not accurately reflect the degree of driver impairment.
To reduce driver impairment, the Commission recommends increased research, police training and public education.
