Drug Testing in Oklahoma

In the state of Oklahoma, drug testing in the workplace is subject to specific laws and regulations that employers must adhere to. It is important for both employers and employees to understand these rules in order to ensure compliance and maintain a safe and drug-free work environment. This article provides an in-depth analysis of Oklahoma’s drug testing laws, covering topics such as testing requirements, types of tests, procedures, and other relevant considerations.

Understanding Oklahoma’s Drug Testing Laws

Oklahoma is classified as a “mandatory state” when it comes to drug testing. This means that private, non-regulated employers who choose to implement drug testing policies must follow specific rules and regulations. These rules apply to employees assigned to work at any Oklahoma site. While there are no statewide mandates for drug testing, employers must still comply with the state’s general substance abuse policies.

It is essential for employers to have a written drug testing policy that is distributed to all employees. This policy should outline the company’s stance on drug testing, the substances that will be tested for, and the testing procedures that will be followed. In cases where the company substance abuse policy conflicts with the state rules, the state rules will take precedence.

Types of Drug Tests Allowed in Oklahoma

Drug testing in Oklahoma can be conducted using various methods, including urine, saliva, and hair tests. Employers may choose the type of test that best suits their needs and requirements. Additionally, alcohol testing can be performed using breath or saliva tests. It is important for employers to ensure that the testing laboratory they work with is qualified and licensed according to Oklahoma law. All initial positive results must be confirmed, and the results should be available for copying.

Instant Testing and Qualifications

Instant testing, also known as point-of-care testing or POCT, is a method of conducting drug tests that provides immediate results. However, in Oklahoma, instant testing can only be performed by qualified facilities that meet the qualifications established by state law. Employers who wish to conduct instant testing must ensure that the testing facility meets these requirements.

Collection Procedures and Direct Observation

In non-DOT (Department of Transportation) testing cases, direct observed collections are not allowed in Oklahoma. Direct observation refers to the practice of an observer being present during the collection of a urine sample to ensure its integrity. However, it is important to note that DOT testing follows different regulations and may allow for direct observed collections in certain circumstances.

Compensation and Benefits for Test Time

In Oklahoma, all required test time for drug testing is considered “on duty” time for compensation and benefits purposes. This means that employees undergoing drug testing should be compensated for the time spent on the testing process and should not face any negative consequences or loss of benefits due to participating in the test.

Workers’ Compensation and Drug Testing

Oklahoma’s laws regarding workers’ compensation include provisions related to drug testing. If an employee tests positive for the presence of substances such as “huffing” substances, alcohol, illegal drugs, or illegally used chemicals, or refuses to take a drug or alcohol test required by the company, they may be deemed ineligible for workers’ compensation benefits in the event of a workplace injury.

Follow-Up Testing and Time Limitations

Follow-up testing in Oklahoma is limited to a two-year period after an employee returns to work. This means that if an employee has previously tested positive for drugs or alcohol, the employer may require them to undergo follow-up testing for a specified period of time. It is important for employers to establish a clear policy regarding follow-up testing and communicate it to employees.

Medical Marijuana Considerations

Oklahoma has authorized the medical use of CBD (Cannabidiol) for limited medical conditions. However, it is important to note that the use of medical marijuana does not provide immunity from drug testing in the workplace. Employers may still enforce their drug testing policies and take appropriate action based on positive test results, even if an employee has a valid medical marijuana license.

Compliance with Drug Testing Legislation

Private employers in Oklahoma who choose to implement drug testing policies must ensure that they remain in compliance with state laws and regulations. It is essential to regularly review and update drug testing policies to align with any changes in the legal landscape. Employers should also stay informed about any new developments or updates regarding drug testing laws in Oklahoma to ensure ongoing compliance.


Understanding and complying with drug testing laws in Oklahoma is crucial for both employers and employees. By following the state’s rules and regulations, employers can create a safe and drug-free work environment, while employees can be aware of their rights and responsibilities regarding drug testing. It is recommended that employers seek legal advice or consult with a drug testing service provider to ensure full compliance with Oklahoma’s drug testing laws and regulations.

Additional Information: It is important for employers to strike a balance between maintaining a safe work environment and respecting employees’ rights and privacy. Implementing a comprehensive drug testing policy that is fair, consistent, and compliant with state laws can help achieve this balance. Employers should also provide education and resources to employees regarding the effects of drugs and alcohol, as well as the potential consequences of substance abuse in the workplace.
