LANSING MI (WKZO AM/FM) – A state lawmaker has introduced a bill that would modify the legal limit for THC that a motorist could have in their blood, but there are some concerns that it may not be the right way to determine impairment.
State Rep. Pamela Hornberger, a Republican from Macomb County, said that the measure would put appropriate restrictions in place to protect drivers from those who would drive impaired.
However, a professor at MSU who is an expert on cannabis, says that that level of THC can remain in someone’s blood long after the effects of the drug are gone, and that a better assessment would be specific field tests to determine impairment.
