Can I be fired for being a medical marijuana patient?

The Michigan Medical Marihuana Act (MMMA) does not regulate private employment, protect private employees from disciplinary action if they use medical marijuana, or require any private employer to accommodate the use of medical marijuana outside of the workplace.

Michigan is an employment-at-will state and, if you are not protected by an employment contract, you can be fired for any reason or no reason except an illegal reason. An illegal reason would be if you were fired for being a member of a protected class. The MMMA did not create a new protected class of employee in Michigan.

For example, Wal-Mart was allowed to fire its employee, a medical marijuana patient, for a blood test showing positive results for marijuana. The employee did not smoke at work, but he was injured at work and had to submit to a mandatory blood test. He was fired based on a Wal-Mart policy, despite having provided his medical marijuana information.
