Oklahoma’s amendment to its Medical Marijuana and Patient Protection Act takes effect Nov. 1, 2026, under HB 3127. This bill revises the definition of “safety sensitive positions,” implements a zero-tolerance policy, and expands an employer’s authority to act on positive marijuana tests.
Safety Sensitive Positions
Under the original law, “safety sensitive” is subjective, based on what the employer “reasonably believes could affect the safety and health of the employee performing the task or others.” The new definition of “safety sensitive position” covers any position in which the employee performs one or more listed duties, including:
- handling hazardous materials,
- operating vehicles, equipment, machinery, or power tools,
- repairing or maintaining equipment, machinery, or processes that could result in injury or property damage if malfunction occurs,
- firefighting,
- overseeing critical utility infrastructure,
- working with volatile or highly regulated materials,
- dispensing pharmaceuticals,
- carrying a firearm, and
- providing direct patient or child care.
Zero Tolerance
In addition to redefining “safety sensitive position,” HB 3127 also introduces a zero-tolerance drug and alcohol standard for those positions. This standard applies regardless of whether an employer has a policy that permits impairment-based testing or other standards for positions that are not safety sensitive. Furthermore, there is no exception for employees with a medical marijuana license.
Positive Marijuana Tests
Under current law, an employer may not refuse to hire, discipline, discharge, or otherwise penalize an employee based on a positive marijuana test, with two exceptions:
- The applicant or employee does not have a valid medical marijuana license, or
- The licensee possesses, consumes, or is under the influence of medical marijuana at work or during job duties.
HB 3127 adds a third exception:
- The action is taken pursuant to a written drug and alcohol testing policy adopted and enforced in accordance with the Oklahoma Standards for Workplace Drug and Alcohol Testing Act.
Next Steps
Oklahoma employers should review employee positions to determine which ones qualify as safety sensitive positions and are therefore subject to the zero-tolerance standard. If an employer has a drug policy, it should confirm that the policy meets the Oklahoma Standards for Workplace Drug and Alcohol Testing Act.
