Marijuana
Effective January 1, 2024, an employer may not take action based on a positive pre-employment test for cannabis if the test finds an applicant to have nonpsychoactive cannabis metabolites in their hair, blood, urine, or other bodily fluids. The law prohibits discrimination against applicants for off-duty marijuana use.
Employers may use drug tests that assess a range of controlled substances, including cannabis, if the test results provided to the employer do not relate to past cannabis use.
An employer may use a scientifically valid drug screening for cannabis that does not screen for nonpsychoactive cannabis metabolites. However, there are currently no tests that can distinguish between psychoactive cannabis metabolites and nonpsychoactive metabolites. Oral fluid, or saliva, tests can detect recent drug use and can identify the presence of psychoactive cannabis metabolites shortly after cannabis is used. It us unclear whether they would detect only nonpsychoactive metabolites, however.
The marijuana testing restriction does not apply to:
These positions must be identified by the employer prior to the applicant’s application for employment.
Washington's law does not preempt state or federal laws requiring an applicant to be tested for controlled substances.
Post-accident and reasonable suspicion tests for cannabis are allowed.
Unemployment compensation
Washington’s unemployment compensation law provides that alcoholism does not constitute a defense to disqualification from benefits due to misconduct.
State employees
State agencies can test specific employees in safety-sensitive positions based on reasonable suspicion, which must be stated in writing. The agency must have a comprehensive written policy.
