Employer protections & drug testing
Ohio law protects employees from adverse action based solely on off-duty cannabis use, but employers may still restrict use in safety-sensitive roles and enforce workplace policies.
Even in legal states, employers may still drug test and set workplace policies. Off-duty protections vary widely and federal-adjacent roles keep zero-tolerance.
What it means for a drug test
Ohio restricts adverse employment action based solely on off-duty cannabis use, but employers can still test and act for safety-sensitive positions or when impairment is shown. A medical card does not provide blanket protection from testing.
