Will a Failed Drug Test Effect Workers' Compensation Benefits?Many Ohio employers will automatically give you a drug test after a workplace injury. However, in order for a failed drug test to disqualify you from receiving workers' comp benefits, you must have been under the influence at the time of the accident and the impairment must have been the direct cause of the accident. For example, if you were the passenger in a vehicle that crashed while on a work-related trip and you test positive for marijuana use, that should not affect your claim because your impairment had nothing to do with the accident and your injury. However, failing a drug test does mean you should consider hiring an experienced workers' comp attorney to represent you.

Workers' Comp and Drug Testing in Ohio

One of the main tenets of the workers’ compensation system across the U.S. is an injured employee’s ability to obtain benefits regardless of fault. In exchange for reduced liability, employers agree to provide care and compensation even if an employee played a role in the accident or situation that resulted in the illness or injury. There are, however, some key exceptions to this rule. Besides injuries suffered in fights or that occur when an employee violates company policy, drug use can disqualify workers from benefits. Many workers wonder both if their employers may perform drug tests and if it is possible to lose workers’ compensation benefits as a result of a failed test. Here, we look at drug testing and drug policy relevant to Ohio’s workers.

Employers’ Rights to Use Drug Testing in Ohio

Ohio employers are within their rights to perform drug tests on employees. The Ohio Bureau of Workers’ Compensation (BWC) even encourages employers to do so, offering incentives for employers to enroll in a state drug-free workplace initiative. The Drug-Free Safety Program (DFSP) calls for employers to drug test employees after an accident and upon return to work as two of several requirements of the program. Employers are also permitted to test an employee when reasonable suspicion of intoxication or drug use arises. While this program is voluntary and not every Ohio employer will participate, know that drug testing is a common practice and may occur at your place of employment regardless of whether your employer is involved with DFSP or not.

What to Expect From a Drug Test and What They Test For

There are several ways to test a person for drug use, and different employers may elect to use different methods. The most common forms of drug testing include examining samples of urine, hair, blood, breath, or even sweat.

Employers most commonly follow the guidelines set by the national Substance Abuse and Mental Health Services Administration. Under these guidelines, employers will test for:

  • Amphetamines (meth, speed, ecstasy)
  • THC (marijuana)
  • Cocaine and crack
  • Opiates (heroin, morphine, oxycodone)
  • Phencyclidine (PCP)
  • Alcohol

Failing a Drug Test Does Not Automatically Disqualify Workers From Benefits

So, you were involved in an accident at work and failed a subsequent drug test. What now? You still may have workers’ compensation benefits. State law mandates that an employee can only be denied benefits if:

  • He or she was under the influence during the accident or injury. It must be shown that the employee was under the influence when the injury occurred. This means a drug test days or weeks later may not matter. Only timely tests that can scientifically and reliably indicate impairment at a specific time are relevant.


  • The drug or alcohol use was the proximate cause of the injury. Proving an employee was impaired during an injury creates a presumption the drug use caused the accident leading to injury and, without more information, the claim will be denied. However, in Ohio, this is a rebuttable presumption; meaning, if other circumstances caused or contributed to the injury besides the employee’s drug use, it is still possible to obtain benefits.

There are a several other defenses to benefits being denied after a failed drug test. Workers taking medication prescribed by a doctor for a legitimate medical reason, those singled out unfairly among other employees, and anyone subject to inappropriate testing methods could dispute the drug test results.
