Oklahoma Drug Testing Laws and Regulations



Statute of Order

OK Stat. Tit. 40 §551-565

Covered Employers

Public and private employers

Applicant Testing

Applicant testing is authorized with advance notice to applicant and after offer of employment has been made. Notice has to be in writing, describing methods, procedures, and policies in detail. Refusal to undergo drug testing or positive drug test are grounds for not hiring said applicant.

Employee Testing

Employees testing is authorized on 30 days advance notice to employees of policy describing the potential discipline for positive test result. For-cause drug testing, post-accident testing and random drug testing are permissible. Scheduled and random drug testing are mandatory to: police or peace officers; those who are authorized to carry firearms; those whose jobs directly affect the safety of the public; those who work in public hospitals and health centers; and those who work in correctional facilities.

Conditions & Methods

Testing facilities must be duly approved by the health department. Specimen shall be collected and tested by qualified personnel. Procedures must ensure privacy and confidentiality of results. Confirming test must be conducted in case of positive findings.

Important Bulletpoints

  • Apart from compliant applicant testing upon conditional offer of employment, authorized chemical tests for controlled substances include reasonable suspicion, post-accident, random testing (with restrictions to public employers for specific positions; unrestricted for private employers), as part of periodic fitness-for-duty medical examination (same restrictions for public employers apply), and post-rehabilitation testing.
  • The employer’s drug or alcohol testing policy must be compliant with the provisions of the Standards for Workplace Drug and Alcohol Testing Act and must be communicated to employees and prospective employees through posting at prominent employee access areas, personally handing a copy of the policy, through mail, or via e-mail with document receipt capability.
  • The employer shall pay for all costs of the drug or alcohol testing as required including confirmation tests and transportation costs of the employee to the testing laboratory. Employee requested retests for confirmed positives to be paid by the employee unless the results of the retesting come out negative. In such cases the employer pays for the cost of the retest. The time allotted to the tests is to be considered as compensable work time.
  • Collection of samples may be performed on-site but only by qualified individuals as determined by the State Board of Health. Actual testing must be conducted at licensed testing facilities only.
  • An employer requiring or requesting an employee to undergo drug or alcohol testing must also provide an employee assistance program, either in-house or contracted, that provides at the minimum substance dependency evaluation and referral services for counseling, treatment and rehabilitation.
  • An employer may only take adverse employment action upon a confirmed positive test result. An employee’s refusal to undergo compliant drug or alcohol testing is also a basis for disciplinary action. For cases of refusal to test or a confirmed positive test, the employee is considered discharged for misconduct and may be ineligible for benefits.
  • An employee discharged due to a positive drug test or his refusal to undergo drug testing is considered discharged for misconduct and cannot avail of unemployment benefits.

Medical Marijuana Law

Oklahoma has no rules and regulations pertaining to the possession and use of medical marijuana. SB 710, authored by Senator Constance Johnson, calls for the legalization of medical marijuana in the state of Oklahoma. However, this bill was vetoed by the state committee.

Oklahoma expanded the controlled protection of patients who are using low THC, high-CBD cannabis oil for specific medical conditions. In 2015, HB 2835 was passed, allowing adult patients to use low THC, high-CBD cannabis oil. The bill also added to the list of qualifying medical conditions the following: obstinate nausea, vomiting, spasticity due to paraplegia or multiple sclerosis. Note that minors have been covered by the existing law.2 A summary of the law is found here.

Qualifying Medical Conditions:

• Pediatric epilepsy

• Obstinate nausea, vomiting

• Spasticity due to paraplegia

• Multiple Sclerosis


• CBD products are only to be sourced from either mature stalks or seeds of the marijuana plant.

• Prohibits drivers with detectable level of drug metabolite from operating a motor vehicle.

• CBD content should not be greater than 3/10th of 1% THC.

Recreational Marijuana Law

Oklahoma has no recreational marijuana law. Possession and distribution of marijuana is considered a felony.

In the November 8, 2016 elections, 7 measures were voted on by the residents of Oklahoma. Among the State Questions asked, SQ 780 was specifically designed to re classify some non-violent drug and theft-related crimes, and deemed them as misdemeanors instead of felonies. This will effectively reduce maximum penalty to only a year in prison, and reduce the fine to $1,000.

SQ 781 pertains to use the money saved by the reclassification of specific drug and property crimes as misdemeanors, for funding rehabilitation programs. Reduced prison cost as a consequence of implementing SQ 780 will be redistributed to counties for the rehabilitation of criminals. These two SQs are lumped together as without SQ 780, funding for SQ 781 will not exist.

As of July 1st, 2017, State Question 780 was signed into law. The next step is to design a motion for extended medical marijuana laws in Oklahoma.


• First time offenders are given conditional release to opt for probation instead of trial. After probation, the person's criminal record is not affected.

Effects on Drug Testing in the Workplace

Oklahoma employers are allowed to require applicants to undergo drug testing as a condition of employment. They may also require employees to undergo drug testing after an accident in the workplace that caused damage to property, or injury; as back-for-duty fitness test, random drug testing, or following an employee's rehabilitation program. An employer may require drug testing for cause on a particular employee.
