Medical marijuana law doesn’t preempt workplace drug policy

Many states have passed laws in recent years allowing people to use marijuana for medical reasons.

But while these laws may protect users against the police, they won’t necessarily protect them against their employers.

For example, a Wal-Mart employee in Michigan recently sued the company for firing him under its drug-use policy when he tested positive for marijuana. The employee claimed he was wrongfully fired because he used marijuana after work for medical reasons.

But a federal judge ruled that Michigan’s medical marijuana law didn’t prevent a company from disciplining a worker under its drug policy. The law doesn’t require companies to accommodate medical marijuana users, the judge said.

Every state’s law is different, though. Undoubtedly this issue will keep coming up in other states.
