Key Takeaways
- Status: Medical patients only — Protections reach registered or certified medical cannabis patients, not adult-use consumers.
- Main source: NMSA 1978 § 26-2B-9.
- Federal testing rules (DOT and federal workplace programs) apply regardless of state law.
What the law protects
- NMSA 1978 § 26-2B-9(A) makes it unlawful to take adverse employment action against an applicant or employee based on conduct allowed under the Lynn and Erin Compassionate Use Act, unless not doing so would cost the employer a monetary or licensing-related benefit under federal law or regulations.
Exceptions and limits
- Employers may still prohibit, and act on, use of or impairment by medical cannabis on the premises or during hours of employment.
- The protection does not apply to an employee whose employer deems that the employee works in a safety-sensitive position.
Drug testing rules
- The statute does not set testing procedures. The state’s annotation notes a 2016 federal decision holding that the act, combined with the Human Rights Act, did not require an employer to accommodate medical cannabis; that case predates the 2019 employment-protection section.
Notes and history
- History: Laws 2019, ch. 247, § 11 (effective June 14, 2019).
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 New Mexico?
New Mexico’s protection (NMSA 1978 § 26-2B-9) is written for medical cannabis patients. It does not cover adult-use consumers, and employers can still act on use, possession, or impairment at work, plus the other exceptions listed in the statute.
Can New Mexico employers still drug test for THC?
Yes. NMSA 1978 § 26-2B-9 does not ban drug testing; it shapes what an employer may do with the results. Federally required tests, such as DOT-regulated jobs, are unaffected by state law.
Does New Mexico 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.
