Casias v. Wal-Mart Stores, Inc.

**What Happened** Joseph Casias worked for Walmart and was fired after testing positive for marijuana during a drug test. Casias had a medical marijuana card and was legally using marijuana under Michigan's medical marijuana law to treat cancer and an inoperable brain tumor. He sued Walmart and his store manager, claiming he was wrongfully fired for using legally prescribed medical marijuana. **What the Court Decided** The court sided with Walmart and dismissed the case entirely. The judge ruled that Michigan's medical marijuana law does not give employees the right to sue their employers for firing them over marijuana use, even when it's legally prescribed. The court also found that the store manager was improperly included in the lawsuit. **Why This Matters for Workers** This ruling shows that having a medical marijuana card may not protect your job. Even in states where medical marijuana is legal, employers can still fire workers for using it, and employees may have no legal recourse. Workers should understand that workplace drug policies can override state medical marijuana protections, and they should carefully review their company's policies before using medical marijuana.
