New Mexico does not have one general statute that tells private employers when they may or may not drug test. Instead, employers have to read across several separate laws: the Cannabis Regulation Act for adult use cannabis, the Lynn and Erin Compassionate Use Act for medical cannabis patients, the Workers' Compensation Act for intoxication at the time of an injury, and the Unemployment Compensation Law for misconduct disqualification. The full text of New Mexico statutes is compiled at the New Mexico Legislature's statutes portal, which links out to the official compiled code. Nothing in this article is legal advice, and employers building a testing policy should confirm current section language with counsel before relying on it.
Is There a General Drug Testing Statute in New Mexico
No. New Mexico has not enacted a standalone drug free workplace act or a general private sector testing statute the way some other states have. That means a private employer's baseline authority to test applicants and employees for cause, at random, post accident or pre employment comes from ordinary employment at will principles, not from a dedicated testing law. The limits that do exist are carved out in the cannabis statutes described below, in the workers compensation law and in the unemployment law. Employers should not assume a right to test is unlimited just because no specific testing statute restricts it; federal law, contract terms and the cannabis protections below still apply.
Adult Use Cannabis: The Cannabis Regulation Act
New Mexico legalized adult use cannabis in 2021 through the Cannabis Regulation Act. The enacted bill includes a section titled "Employer Protections, Exemptions" that preserves, rather than limits, an employer's authority over workplace cannabis use. Unless the employer and employee have agreed otherwise, the act does not restrict an employer's ability to prohibit or take adverse action against an employee for impairment by or possession or use of intoxicating substances at work or during work hours, does not require an employer to violate federal law or lose federal funding or a federal contract, and does not prevent an employer from adopting and enforcing a written zero tolerance policy, including one that allows discipline or termination based on a positive test for any amount of THC or its metabolite. That language appears in the enacted 2021 special session House Bill 2, now compiled as Chapter 26, Article 2C of the New Mexico Statutes. In short, legalizing adult use cannabis did not create a right for employees to use it on the job or to be free of a zero tolerance policy at a private employer.
The same act also defines a "safety sensitive position" as one in which performance by a person under the influence of drugs or alcohol would create an immediate or direct threat of injury or death to that person or to another. That definition is the one employers should point to when they classify a role as safety sensitive for cannabis policy purposes, rather than relying on an informal label.
Medical Cannabis: The Lynn and Erin Compassionate Use Act
Medical cannabis patients have narrower, but real, employment protections under the Lynn and Erin Compassionate Use Act. A 2019 amendment added an employment protections section providing that, unless a failure to do so would cause the employer to lose a monetary or licensing related benefit under federal law or federal regulations, it is unlawful to take an adverse employment action against an applicant or employee based on conduct allowed under the act, meaning the patient's registered medical use off the job. That same section carves out two exceptions: it does not restrict an employer's ability to prohibit or discipline use of, or impairment by, medical cannabis on the employer's premises or during work hours, and it does not apply to an employee whose employer deems the position safety sensitive. This text is in the enacted 2019 Senate Bill 406, generally cited as NMSA 1978 Section 26-2B-9 of the compiled code linked from the legislature's statutes portal.
In practice this means a registered patient who tests positive for THC generally may not be fired for that result alone if the position is not safety sensitive and no federal funding or contract risk is involved. An employer may still act if the patient was impaired or used cannabis at work or during work hours, or if the employer has determined in good faith that the role is safety sensitive. Because federal law still treats cannabis as a controlled substance, employers with federal contracts, federal funding or positions regulated under the Department of Transportation rules below should document that basis carefully, and should get counsel involved before treating a patient's positive result as cause for termination.
Workers Compensation and Intoxication
New Mexico's Workers' Compensation Act addresses intoxication as a factor that can reduce or affect a benefits claim when intoxication contributed to the accident. The Workers' Compensation Administration posts the current compiled Workers' Compensation Act, Chapter 52, and its governing rules at its legal resources page. Because the exact proof requirements and any benefit reduction percentage can be amended and are fact specific to each claim, employers and claims handlers should confirm the current section text directly rather than relying on a general summary, and should not assume a positive post accident test by itself proves the legal intoxication standard without a documented chain of custody and, where medication is involved, review by a medical review officer.
Unemployment Benefits: Misconduct for a Failed or Refused Test
New Mexico's Unemployment Compensation Law disqualifies a claimant from benefits for misconduct connected with the work. A discharge tied to violating a clear, written drug testing policy, including a confirmed positive result or a refusal to test, can be treated as misconduct in an unemployment claim, but the outcome depends on whether the employer had a written policy, applied it consistently and can document the result. The New Mexico Department of Workforce Solutions administers unemployment claims and posts program information at its unemployment insurance program page; the underlying statute is part of the compiled code linked from the legislature's statutes portal. Employers should keep the signed policy acknowledgment, the chain of custody paperwork and, for any medication related result, the medical review officer's determination, since an unemployment hearing officer will ask for that documentation.
Public Employees and State Personnel Rules
New Mexico does not appear to run a single statewide drug free workplace program covering every state agency the way some states do for their executive branch workforce. State classified employees are instead subject to rules adopted by the State Personnel Board, which an agency can view through the State Personnel Office's board rules page. A public employer should confirm whether its own agency, board or local government has adopted a specific drug free workplace rule or policy rather than assuming one statewide rule applies, and should still apply the Compassionate Use Act and Cannabis Regulation Act protections described above to its own employees.
DOT Covered Positions: Federal Law Still Controls
None of the state protections above change testing for a position covered by United States Department of Transportation drug and alcohol testing rules, such as a commercial driver subject to Federal Motor Carrier Safety Administration rules. Those positions are governed by 49 CFR Part 40, the federal rule that sets collection, laboratory and medical review officer procedures, and federal law treats marijuana as a prohibited substance regardless of a state medical or adult use card. A DOT regulated employer may not excuse a verified positive result because the employee is a New Mexico registered medical cannabis patient.
| Testing scenario | General New Mexico rule | Primary source |
|---|---|---|
| Private employer, no cannabis involved | No general state testing statute; employer policy and at will principles govern | NM Legislature statutes portal |
| Adult use cannabis, non safety sensitive job | Employer may still enforce a written zero tolerance policy | Cannabis Regulation Act, enacted bill |
| Registered medical cannabis patient | Adverse action generally barred unless safety sensitive, on premises impairment, or federal funding risk | 2019 Senate Bill 406, employment protections |
| Workplace injury with suspected intoxication | Intoxication may affect a workers comp claim; proof and effect are fact specific | Workers' Compensation Administration |
| Discharge for a positive or refused test | May be treated as misconduct if tied to a written, consistently applied policy | Dept. of Workforce Solutions |
| DOT safety sensitive function | Federal rule controls; state cannabis protections do not apply | 49 CFR Part 40 |
Building a Written Policy That Holds Up
Because so much of the outcome in New Mexico depends on whether an employer had a clear written policy and applied it consistently, the policy itself is the employer's main protection. A usable policy generally states which positions are safety sensitive and why, states how a zero tolerance rule applies to on the job impairment versus off duty legal conduct, explains that a positive result tied to a prescribed medication goes through a medical review officer before any decision is made, and is given to and signed by every employee before enforcement begins. Employers comparing how other states draw these same lines can see the broader pattern in our roundup of workplace drug testing laws by state and in our look at what employers can still do where marijuana is legal.

Frequently asked questions
Does New Mexico require private employers to drug test?
No. New Mexico has no general statute requiring or standardizing private employer drug testing. Testing is governed by the employer's own policy, subject to the cannabis, workers comp and unemployment rules described above.
Can a New Mexico employer fire someone for off duty medical cannabis use?
Generally, no, unless the position is safety sensitive, the use or impairment happened at work or during work hours, or a federal funding or contract requirement is at stake. Employers should confirm the current statute and get counsel involved before acting on a registered patient's positive result.
Can an adult use cannabis cardholder be disciplined for a positive test at work?
The Cannabis Regulation Act does not stop an employer from enforcing a written zero tolerance policy for on the job impairment, possession or use, and it does not require an employer to accommodate cannabis use to keep a federal contract or funding.
Does a positive post accident test automatically reduce a workers comp claim?
Not automatically. Intoxication can be a factor in a New Mexico workers compensation claim, but the proof needed and the effect on benefits are fact specific and the current statute should be confirmed with the Workers' Compensation Administration or counsel rather than assumed.
Can someone collect unemployment after being fired for a failed drug test?
It depends on whether the employer had a written, consistently applied policy and can document the result as misconduct connected with the work. A claim without that documentation is harder for an employer to defend.
Do New Mexico cannabis protections apply to a DOT regulated driver position?
No. Positions covered by 49 CFR Part 40, including most commercial drivers, remain subject to federal testing rules regardless of a state medical or adult use cannabis card.
