Marijuana – Ohio has a medical marijuana law. This does not mean that employers in Ohio cannot drug test or drug test for marijuana. Employers are not limited in any employment actions based on an employee's medical marijuana use. A person who is discharged from employment because of that person's use of medical marijuana should be considered to have been terminated for just cause for purposes of [unemployment] if the person's use of medical marijuana violated an employer's drug-free workplace policy, zero-tolerance policy, or other formal program or policy regulating the use of medical marijuana.

Nothing in the Ohio medical marijuana law prohibits an employer from establishing and enforcing a drug testing policy, drug-free workplace policy, or zero-tolerance drug policy. In fact, in Ohio, the drug-free workplace program is strongly encouraged by the Ohio Bureau of Workers' Compensation. Qualifying employers can receive discounts on workers' compensation insurance when implementing a comprehensive drug-free workplace program.
