Refusing to take this test has driver's license consequences that are separate from those that result from any conviction that flows from the traffic stop. You may request an administrative hearing regarding the alleged refusal. At the hearing, the law enforcement officer would have to prove certain things before the statutory consequences would apply. If you do not request the hearing, or if the officer proves his or her case at the hearing, the following will happen:
Six points will be added to your driving record.
Your license will be suspended for 1 year if it is the first time you refused to take the test under the Implied Consent law.
Your license will be suspended for 2 years if you refused to take the test one or more times within the preceding 7 years. There are no hardship appeals in circuit court for a restricted license in this situation.
If you refuse to take the test, or if the test shows that your BAC is 0.08 or higher, the law enforcement officer will destroy your driver license, and will issue a paper permit to you. You may drive on the paper permit until your criminal case is resolved in court.

 From NORML.org: The Michigan Supreme Court has found that inert metabolites of marijuana do not constitute schedule I controlled substances. The court found that natural byproducts created by body during break down of THC were not derivative of marijuana. Inert metabolites do not constitute schedule I controlled substance, in part because they do have any known pharmacological effect, relate to level of THC-related impairment, and do not have potential for abuse and dependence. People v. Feezel, 783 N.W.2d 67(2010).
The Michigan Supreme Court has separately determined that the protections of the state's medical marijuana act trump the state's zero tolerance per se law for the presence of THC in blood. This means that qualified patients may not be charged under the state's zero tolerance per se DUI statute. Rather, the state would have to show proof of impairment in order to gain a DUI drug conviction. This zero tolerance standard does apply to non-patients. People v. Koon, 2013.
