Michigan Driving Commission Recommends Against Chemical Testing for Marijuana Based DUI Charges

Although the use of marijuana is legal in many states, drivers are still prohibited from operating a vehicle while impaired, which includes impairment due to marijuana. States across the country have struggled with the issue of how to test whether a person is under the influence of marijuana, with some states, including Illinois, choosing to employ blood tests. Recently, Michigan’s Impaired Driving Commission has recommended that the state bypass blood tests to prove a person is under the influence of marijuana, and choose to employ field sobriety tests instead. If you live in Illinois and were recently charged with a marijuana-related DUI charge it is vital to retain a skilled Illinois DUI attorney to assist you in planning your defense.

Michigan’s Impaired Driving Commission’s Findings

Following a two-year review, the State Impaired Driving Commission recommended that the state legislature not set a limit for how much THC a driver is permitted to have in his or her blood. Rather, the Commission recommended that police investing a driver for suspected intoxication due to marijuana employ filed sobriety tests to assess the person’s fitness to operate a motor vehicle. This recommendation was based on the fact that THC blood levels do not correlate to a person’s level of intoxication. THC, unlike alcohol, is fat soluble and stays in a person’s body well after a person is no longer affected by the marijuana he or she ingested. Further, the Commission found that THC limits set in other states are wholly arbitrary and are not based on sound evidence. Additionally, the State has been able to convict people of DUIs absent any chemical testing. While Michigan currently has a zero-tolerance level for any THC in a driver’s blood it will be interesting to see if the law changes based on the Commission’s recommendations.

Illinois Marijuana Law

Currently, under Illinois law, a person is not permitted to drive while under the influence of any drug, including marijuana, that affects the person to the point where he is or she is incapable of driving safely. Thus, a person can be charged with DUI for the use of marijuana. Illinois has set a threshold of 5 nanograms of THC in whole blood for the level at which it will be presumed a driver was under the influence of marijuana. For cases where the defendant’s blood concentration of THC is less than 5 nanograms, the person’s THC blood level can be considered along with other competent evidence to determine if the person was under the influence of marijuana. While the Michigan Impaired Driving Commission’s recent findings will not affect Illinois law, they may be persuasive as to whether Illinois and other states should continue to employ THC blood levels in the prosecution of DUIs.
