Nevada Drug Testing Laws for Employers

No Program Rules

There is no comprehensive Nevada testing statute. Nothing prescribes policy contents, notice periods, laboratory accreditation for employment testing, confirmation testing, a medical review officer step, a result-notification deadline or an employee appeal procedure. Laboratory licensing appears only on the workers' compensation side.

What Nevada regulates is consequences, at three points.

One: The Hiring Decision

NRS 613.132(1) makes it unlawful to fail or refuse to hire a prospective employee because a screening test indicated the presence of marijuana. Read the verb carefully — it bars the decision, not the test. A multi-state employer can keep marijuana on its national applicant panel in Nevada; what it cannot do is screen people out on that result unless an exemption applies.

The exemptions are firefighters, emergency medical technicians, positions requiring operation of a motor vehicle for which federal or state law requires screening, and positions that in the employer's determination could adversely affect the safety of others — plus conflicts with a contract or collective bargaining agreement, conflicts with federal law, and federally grant-funded positions.

That fourth exemption is unusually generous because the statute commits the judgment to the employer. It is also the one most likely to be tested. An employer that designates an entire workforce as safety-affecting has effectively read the statute out of existence; an employer that can point to a specific, written rationale for each job family is in a much better position. Nothing in NRS 613.132 restricts applicant testing for substances other than marijuana.

Two: The First Thirty Days

This provision is easy to overlook because it sits inside a section that otherwise reads as a hiring rule, and it is the one that reaches current employees.

Under NRS 613.132(3), where an employer requires an employee to submit to a screening test within the first 30 days of employment, the employee may submit to an additional screening test at their own expense to rebut the initial result, and the employer shall accept and give appropriate consideration to that result.

Two practical consequences. If you test during onboarding, or drop new hires straight into a random pool, you need a documented process for receiving an employee-funded second test and for demonstrating that it was actually considered before any decision — "appropriate consideration" is a standard someone can be asked to evidence.

And a scope question the statute leaves open: subsection 3 does not repeat the word marijuana, while screening test is defined broadly as a test of blood, urine, hair or saliva to detect the general presence of a controlled substance or any other drug. Whether the rebuttal right reaches beyond marijuana is not resolved on the face of the statute. The practical answer is the same either way — build the process so it works for any substance.

Three: Medical Cannabis Patients

Nevada is in the minority of states with an affirmative accommodation duty. NRS 678C.850(2) confirms no employer must allow medical use in the workplace. Subsection 3 then requires the employer to attempt to make reasonable accommodations for the medical needs of an employee who engages in medical use and holds a valid registry identification card, provided the accommodation would not pose a threat of harm or danger to persons or property, impose an undue hardship, or prohibit the employee from fulfilling any and all of their job responsibilities.

Subsections 4 and 5 carve out law enforcement agencies — defined to include the Office of the Attorney General, district attorneys' offices, the Nevada Gaming Control Board and their attorneys, investigators and employees, plus other Nevada law enforcement agencies and their peace officers — which may preclude medical use entirely.

For everyone else, a cardholder's positive should route into an interactive accommodation review rather than straight to termination. That is a different workflow from the one most national programs run, and it needs to exist before the first case rather than after.

For adult use, the position is much lighter: NRS 678D.510(1)(a) preserves an employer's ability to maintain, enact and enforce a workplace policy prohibiting or restricting conduct the adult-use chapter otherwise permits, and NRS 613.132 does not create an off-duty protection for current employees.

The Post-Accident Payoff

Nevada has no drug-free workplace certification and no premium credit. What it has is one of the most concrete benefit denials in the country, with the thresholds written into the statute.

NRS 616C.230(1)(c) denies compensation for an injury occurring while the employee was intoxicated, and (1)(d) does the same where the employee was under the influence of a controlled or prohibited substance — in both cases unless the employee proves by clear and convincing evidence that the condition was not the proximate cause. That is a demanding burden placed on the employee rather than the employer.

The statute then sets nanogram-per-milliliter thresholds in a table, paired for urine and blood: amphetamine 500 and 100; cocaine and cocaine metabolite 150 and 50; heroin and morphine 2,000 and 50; 6-monoacetyl morphine 10 and 10; LSD 25 and 10; methamphetamine 500 and 100; phencyclidine 25 and 10. Marijuana is listed with a single figure of 2 rather than the paired values given for every other substance, and the source does not make clear which specimen it applies to. We are not going to guess — confirm that one with counsel before designing a panel around it.

Two procedural conditions attach and both are easy to satisfy if you know about them: the testing laboratory must be licensed under NRS chapter 652, and results of testing must be released to the employer on request. The provision applies only where the employee did not have a current, lawful prescription in their own name.

The Lawful Products Statute

NRS 613.333(1) makes it an unlawful employment practice to refuse to hire, discharge or otherwise discriminate against an employee because they engage in the lawful use in this state of any product outside the employer's premises during nonworking hours, where that use does not adversely affect job performance or the safety of other employees. Whether cannabis is a product used "lawfully" for that purpose, given its federal status, is a question that turns on case law rather than the statute, and we are not resolving it here.

Where This Lands

Nevada's employment base is dominated by casino gaming, hospitality and tourism, alongside construction, transportation and warehousing, mining, healthcare, and a growing data center and advanced manufacturing sector. Hospitality in particular hires at volume and at speed, which makes the applicant marijuana rule and the thirty-day retest right the two provisions most likely to be hit repeatedly — and therefore the two worth building into the process rather than handling case by case.
