Nurses: Marijuana is still Illegal in Ohio, and a Positive Drug Screen could lead to Discipline

Marijuana for medical or recreational purposes is now legal in some states, such as Colorado and Oregon. However, use of marijuana is still illegal in Ohio. If employed as a nurse, you can be subjected to pre-employment, for cause, or random drug tests. If you test positive for marijuana, you may be terminated from your job and may be subjected to discipline by the Ohio Board of Nursing. Chemicals in marijuana, mainly THC, can show on a urine, blood, saliva or hair follicle drug test after 120 or more days, based on usage and other personal factors. (See for guidance on drug testing).

According to RC 4723.28(B)(8), it is a disciplinable offense for a nurse to be self-administering or otherwise taking into the body any dangerous drug, as defined in RC 4729.01, in any way that is not in accordance with a legal, valid prescription issued for that individual, or self-administering or otherwise taking into the body any drug that is a Schedule I controlled substance. (Marijuana is defined as a Schedule I substance.)

Courts have held that an employee is not protected from a wrongful discharge even if they are lawfully taking medical marijuana, and test positive at work. (Coats v. Dish Network). This is because marijuana is unlawful under Federal Law, which the court determined prevails in this situation.

The Ohio Board of Nursing routinely takes disciplinary action against a nurse who tests positive for marijuana, even in cases where the nurse has consumed marijuana in a legal jurisdiction. Therefore, it is important for Ohio nurses to be aware of the risks they take if consuming marijuana, whether it be legally or illegally. Testing positive on a drug screen may result in a disciplinary action against your nursing license.
