Wisconsin Drug Testing Laws

Wisconsin has its set of regulations governing drug testing in workplaces. Employers have the right to enforce drug-free environments while respecting the rights and privacy of their employees.

Marijuana in Wisconsin: As of 2022, recreational marijuana use is illegal in Wisconsin. Medical marijuana use is also not allowed, with some exceptions for CBD oil under specific conditions. Employers typically are not required to accommodate medical marijuana use, but they must be conscious of not discriminating based on the underlying medical condition if CBD oil is being used legally.
