Employer Concerns – Significant to Review

  • Marijuana use in Michigan is legal both medical and recreational.
  • Nothing in the law requires an employer to accommodate use or being under the influence of marijuana in the workplace.
  • Employers may discipline an employee for the violation of a drug-free workplace policy including being under the influence.
  • Impaired driving violation denotes zero tolerance of any level of THC. However, Michigan’s Supreme Court separately determined that protections of the state’s medical marijuana law trump the state’s zero tolerance DUI law and the state must show evidence of impairment to qualify for a DUI conviction.
  • Michigan employers should address marijuana in their drug free workplace policies.


  • Drug testing is legal in Michigan including testing for marijuana
  • An employer may discipline an employee for a drug-free workplace policy violation up to and including terminating an employee for testing positive for marijuana on a drug test even when the use was off-duty.

  • Employers may discipline an employee for the violation of a drug-free workplace policy including being under the influence.
