New Jersey drug testing laws for employers

New Jersey has no general drug testing law for private employers, but its adult-use cannabis law limits what you can do with a marijuana result. You may still test, including random and pre-employment tests, but you may not act against a worker only because cannabis metabolites show up. Medical cannabis patients also get a written chance to explain a positive test.

Have a whole roster to keep current every month? DOT fleets: Pact's monthly DOT program, $25 a driver a month ($99 minimum), or $19 a month for an owner-operator. Nursing homes, hospice and home care: staff credential tracking, $10 a staff member a month ($250 minimum). First month free.

The state law

• We found no New Jersey law that sets general drug testing rules (written policy, notice period, lab rules) for private employers (no statute found).
• The state's cannabis law lets you keep a drug- and alcohol-free workplace and ban cannabis use and impairment during work hours (N.J.S.A. 24:6I-52(b)(1)(a)).
• The law says a cannabis drug test must include a scientific test (blood, urine or saliva) plus a physical evaluation by a person certified to judge impairment (N.J.S.A. 24:6I-52(a)(1)).
• Since a 2026 amendment, that certified person is called a Workplace Impairment Recognition Evaluator, and the Cannabis Regulatory Commission must set the training standards (N.J.S.A. 24:6I-52(a)(2), as amended by P.L.2025, c.325).
• A state rule says no physical evaluation is required until the Commission sets those certification standards (N.J.A.C. 17:30-2.1(e)).
• The Commission's guidance says a metabolite-only positive is not enough, but a positive test plus written, documented signs of impairment at work may support discipline (NJ-CRC Workplace Impairment Guidance, Sept. 9, 2022).

Testing applicants

• You may test applicants as part of pre-employment screening (N.J.S.A. 24:6I-52(a)(1)).
• You may not refuse to hire someone because they do or do not use cannabis (N.J.S.A. 24:6I-52(a)(1)).
• If an applicant tests positive for cannabis, you must give written notice of their right to give a medical explanation (N.J.S.A. 24:6I-6.1(b)(1)).
• The applicant then has 3 working days to explain the result or ask for a retest of the same sample at their own cost (N.J.S.A. 24:6I-6.1(b)(2)).

Random testing

• The cannabis law expressly allows random testing by the employer (N.J.S.A. 24:6I-52(a)(1)).
• A cannabis positive from a random test still cannot be the only reason for action; pair it with documented evidence of impairment at work (N.J.S.A. 24:6I-52(a)(1); NJ-CRC Workplace Impairment Guidance, Sept. 9, 2022).
• We found no state law that limits random testing for other drugs by private employers (no statute found).

Marijuana (recreational)

• You may not take adverse action against a worker solely because cannabis metabolites are in their body from lawful off-duty use (N.J.S.A. 24:6I-52(a)(1)).
• You may test on reasonable suspicion of use at work, on observable signs of cannabis intoxication, after a work accident you investigate, at random, or before hire (N.J.S.A. 24:6I-52(a)(1)).
• You do not have to allow cannabis use, possession or impairment at work (N.J.S.A. 24:6I-52(b)(1)(a)).
• If the law causes a provable problem with a federal contract, you may follow federal rules instead (N.J.S.A. 24:6I-52(b)(1)(b)).
• You may not act against an employee solely because they are a registered medical cannabis patient (N.J.S.A. 24:6I-6.1(a)).
• If your policy includes testing and a worker tests positive for cannabis, give written notice of the right to explain; they have 3 working days to respond or request a paid-by-them retest (N.J.S.A. 24:6I-6.1(b)).
• The medical law does not stop you from acting on use or possession during work hours or on work premises (N.J.S.A. 24:6I-6.1(c)(1)).

Also good to know

• P.L.2025, c.325 was approved January 20, 2026 and took effect 90 days later; it renamed the evaluator and kept the testing rules (P.L.2025, c.325, sec. 5 and 12).
