Recreational and Medical Marijuana Michigan's legalization of recreational marijuana does not override employers' policies to maintain a drug-free workplace, nor does it prohibit disciplinary actions for violating drug policies. Employers are not required to accommodate recreational or medicinal marijuana use, especially in sectors like transportation and those with federal contracts.
Instant or POCT Testing Point-of-care testing and instant drug tests for employees are permitted in Michigan.
Specimens Tested Michigan laws do not specify the types of specimens that can be used for employment drug and alcohol testing.
Substances Screened Michigan drug tests may check for any illegal drugs and/or alcohol.
Laboratories While there is no Michigan state law regulating the choice of laboratories for drug testing, the use of a certified laboratory is highly recommended.
