New Hampshire drug testing laws for employers: pre-employment testing rules (2026)

New Hampshire has no statewide law that regulates drug testing by private employers, as of October 2026: we found no testing statute in the New Hampshire Revised Statutes, and the state Human Rights Commission's guidance says an employer "is permitted to conduct initial and random drug testing, if it does so for all candidates and employees." Two rules shape a program anyway. The therapeutic cannabis law, RSA 126-X, says employers need not accommodate cannabis use at work, and the New Hampshire Supreme Court held in Paine v. Ride-Away (2022) that off-site therapeutic cannabis cannot be ruled out as a reasonable accommodation under the state's anti-discrimination law. Adult-use cannabis is not legal; the Senate laid HB 186 on the table on March 5, 2026.

Does New Hampshire have a drug testing law for private employers?

No. Unlike neighboring Vermont and Maine, which set out testing procedures in statute, New Hampshire leaves private-sector testing to the employer's own policy. Our guide to hiring employees in New Hampshire reached the same conclusion. Four sources fill the gap:

• the Human Rights Commission's guidance on drugs, alcohol and addiction;
• the Law Against Discrimination, RSA 354-A, which covers employers with six or more employees (RSA 354-A:2, VII) and requires reasonable accommodation for "a qualified individual with a disability who is an applicant or employee" (RSA 354-A:7, VII(a));
• the therapeutic cannabis law, RSA 126-X; and
• federal rules for DOT-regulated jobs and federal contractors.

What does the Human Rights Commission say about drug testing?

The Commission enforces RSA 354-A and its guidance is the closest thing New Hampshire has to a testing rulebook:

• Test everyone the same way. "An employer is permitted to conduct initial and random drug testing, if it does so for all candidates and employees."
• Ask about lawful use before deciding. "An employer should give anyone subject to drug testing an opportunity to provide information about lawful drug use that may cause a drug test result that's positive for opioid or marijuana use." As long as the person can perform the job safely and effectively, the Commission says, the employer can reasonably accommodate a positive and lawful screen.
• Recovery is protected. People in recovery from opioid or substance use are covered as disabled, and a person taking an opioid medication as directed for a recovery program has a valid prescription. The Commission says a person cannot be denied a job because they are in a recovery program unless they cannot do the job safely and effectively.
• Current illegal use is not protected. RSA 354-A:2, IV excludes "current, illegal use of or addiction to a controlled substance" as defined in the federal Controlled Substances Act from the definition of disability.

The practical result is a two-step process: a confirmed laboratory result, then a private conversation, usually through a medical review officer, about prescriptions or therapeutic cannabis before any decision.

Do New Hampshire employers have to accommodate therapeutic cannabis?

At work, no. RSA 126-X:3, III(c) says the chapter does not require "any accommodation of the therapeutic use of cannabis on the property or premises of any place of employment" and "shall in no way limit an employer's ability to discipline an employee for ingesting cannabis in the workplace or for working while under the influence of cannabis." Section 126-X:3, II also leaves patients exposed to arrest for being under the influence, or possessing cannabis, at a place of employment without the employer's written permission.

Away from work, the answer is less simple. RSA 126-X:2 says a qualifying patient with a registry card shall not be "denied any right or privilege" for therapeutic use within the two-ounce limit. In Paine v. Ride-Away, Inc., decided January 14, 2022, the complaint alleged that an automotive detailer with post-traumatic stress disorder enrolled in the therapeutic cannabis program and asked for an exception from his employer's drug testing policy, without asking to use or keep cannabis at work, and was terminated. The Supreme Court held that the trial court "erred in determining that the use of therapeutic cannabis prescribed in accordance with RSA chapter 126-X cannot, as a matter of law, be a reasonable accommodation" under RSA 354-A, because the disability was PTSD, not drug use, and reasonableness "should be decided on a case-by-case basis." The court reversed and sent the case back; it did not hold that the accommodation was required.

For hiring, that means a blanket rule rejecting every therapeutic cannabis patient who tests positive is risky in New Hampshire, because RSA 354-A:7 reaches applicants as well as employees. Where a candidate discloses a registry card and a disability, assess the specific job: safety-sensitive duties, DOT coverage and federal contract obligations can make an accommodation unreasonable, and an office role may not.

Is recreational marijuana legal in New Hampshire?

No. HB 186, "relative to the legalization and regulation of cannabis," passed the House on January 7, 2026 (division vote 208-135). In the Senate, the Judiciary Committee recommended it be found inexpedient to legislate by a 2-1 vote, and on March 5, 2026 the Senate laid it on the table by a 15-9 roll call. The General Court's docket shows no later action as of October 2026. Only registered therapeutic cannabis patients may lawfully possess cannabis under New Hampshire law, so a THC positive from a candidate without a registry card can be handled under your ordinary policy.

If the job is performed across the state line, in Massachusetts, Maine or Vermont, follow that state's rules for the job.

What else limits an employer's off-duty rules in New Hampshire?

• Tobacco. RSA 275:37-a bars requiring, as a condition of employment, that "any employee or applicant for employment abstain from using tobacco products outside the course of employment." Keep nicotine off a drug panel used to make hiring decisions.
• Workers' compensation. Under RSA 281-A:14, the employer is not liable for an injury "caused in whole or in part by the intoxication" of the worker, unless the employer knew the employee was intoxicated. A documented post-accident testing practice helps prove it.

Which federal rules still apply in New Hampshire?

• DOT-regulated roles. Drivers and other covered transportation workers follow 49 CFR Part 40, with a verified negative pre-employment result before the first safety-sensitive function (49 CFR 382.301). No accommodation analysis under state law overrides that.
• Rescheduling. The April 28, 2026 final order moved FDA-approved and state-medical-license marijuana to Schedule III, but DOT's Part 40 Q&A, updated May 15, 2026, says a state card or certification does not let a medical review officer verify a marijuana positive as negative.
• Federal contractors follow the FAR Drug-Free Workplace clause.
• The ADA treats a test for illegal drugs as outside its medical exam rules, but questions about prescriptions after a positive are disability-related; see pre-employment medical exams under the ADA.

What should staffing agencies placing workers in New Hampshire do?

• Apply the same panel to the same work. The Commission's guidance turns on testing "all candidates," so decide by job type which candidates are tested and do not test some and waive others.
• Route positives through a medical review officer. That gives every candidate the chance the Commission expects to explain prescriptions or therapeutic cannabis, without your recruiters hearing medical details.
• Separate work-time use from off-site use. You may bar cannabis at work and impairment on the job; a candidate's off-site therapeutic use for a disability calls for an individual assessment of the assignment.
• Mind the client's site. For assignments in Massachusetts, Maine or Vermont, screen under that state's rules.

For registration, see New Hampshire staffing agency licensing; for criminal history and other checks, New Hampshire background check laws; and for recorded screening calls, New Hampshire's recording consent law, which requires every party's consent.

A checklist before you test a candidate in New Hampshire

1. Write a policy that says which jobs require a pre-employment test and apply it to every candidate for those jobs.

4. Before rejecting a registry cardholder, assess the specific job and record why an accommodation is or is not reasonable.
5. Leave tobacco off any test used for hiring decisions.
6. Draft from the drug testing policy template and compare states in drug testing laws in hiring.
