Marijuana in the Workplace: What Employers Need to Know in 2026
Updated November 2026
Marijuana laws continue to evolve, and employers are facing new questions about drug testing, workplace safety, employee protections, and federal regulations.
For organizations managing drug-free workplace programs, the challenge is understanding which rules have changed, which remain in effect, and how to respond consistently when concerns arise.
What Changed in 2026?
In April 2026, the U.S. Department of Justice issued a final rule moving certain FDA-approved marijuana products and marijuana products covered by state medical marijuana licenses from Schedule I to Schedule III under the Controlled Substances Act.
This was a significant federal development, but it did not legalize marijuana across the country or automatically change workplace drug-testing requirements. Broader federal rescheduling remains a separate regulatory process.
What About DOT-Regulated Employees?
Employers with DOT-regulated, safety-sensitive employees must continue following applicable federal drug and alcohol testing requirements.
In May 2026, the Department of Transportation clarified that a state medical marijuana card, physician recommendation, or dispensary receipt does not provide a legitimate medical explanation for a positive DOT marijuana test.
Employers should not assume that changes in federal drug scheduling eliminate existing DOT testing obligations.
Does a Positive Marijuana Test Mean an Employee Is Impaired?
Not necessarily.
Marijuana can remain detectable after its impairing effects have passed. As a result, a positive test does not automatically establish that an employee was impaired at the time of testing.
Employers should understand the purpose and limitations of their testing methods, train supervisors to document observable concerns, and follow their established policies.
What Should Employers Review?
As marijuana laws continue changing, employers should evaluate:
- Whether their drug-free workplace policies reflect applicable federal and state requirements.
- How marijuana testing applies to safety-sensitive and non-safety-sensitive employees.
- Whether supervisors understand reasonable suspicion procedures and objective documentation.
- How positive test results are reviewed and communicated.
- Whether employees clearly understand workplace expectations and testing procedures.
