Nevada cannabis employment and drug testing law
Hiring-stage protections only. Employers can’t refuse to hire based on a pre-employment test showing marijuana, and new hires tested in their first 30 days may rebut with a second test. Status: Hiring-stage protections only — State law limits some pre-employment testing or hiring decisions, but not discipline of current employees generally.

Key Takeaways
- Status: Hiring-stage protections only — State law limits some pre-employment testing or hiring decisions, but not discipline of current employees generally.
- Main source: NRS 613.132.
- Federal testing rules (DOT and federal workplace programs) apply regardless of state law.
What the law protects
- NRS 613.132 makes it unlawful to fail or refuse to hire a prospective employee because they submitted to a screening test that detected marijuana.
- If an employer requires a screening test within the first 30 days of employment, the employee may submit to an additional test, at their own expense, to rebut the result, and the employer must give it appropriate consideration.
Exceptions and limits
- The hiring protection does not apply to firefighters, emergency medical technicians, positions that require operating a motor vehicle where federal or state law requires screening, or positions that the employer determines could adversely affect the safety of others.
- It does not apply where it conflicts with an employment contract or collective bargaining agreement, with federal law, or with positions funded by a federal grant.
- It protects applicants and new hires; it does not stop discipline of existing employees for workplace impairment.
Drug testing rules
- “Screening test” covers tests of a person’s blood, urine, hair, or saliva.
Federal law and testing
Federal rules still apply. Under the U.S. DOT’s testing rules, a Medical Review Officer must not verify a test as negative because a physician recommended a Schedule I drug under a state “medical marijuana” law, and must not accept use of hemp or other non-prescription marijuana-related products as an explanation (49 CFR § 40.151(e)–(f)). That covers safety-sensitive transportation workers regardless of state law.
Federal workplace drug testing programs follow HHS Mandatory Guidelines, which set the cannabis testing panel and cutoffs for urine and oral fluid (Federal Register, March 13, 2026). Most state protections above include an exception where federal law, a federal contract, or federal funding requires otherwise.

Common questions
Can you be fired for using cannabis in Nevada?
Nevada’s protection (NRS 613.132) mainly applies at the hiring stage. It does not generally stop an employer from disciplining a current employee for impairment or a policy violation, and it has exceptions for listed safety roles and federal requirements.
Can Nevada employers still drug test for THC?
Testing is limited in some situations but not banned outright. Read the testing section above for what NRS 613.132 allows, and remember that federally required tests (for example DOT-regulated jobs) are unaffected.
Does Nevada law protect CDL drivers or federal workers?
No state law overrides federal testing rules. DOT-regulated employees remain subject to federal cannabis testing, and a state medical recommendation is not an accepted explanation for a positive result.
