Key Takeaways
- Status: Off-duty use protected — State law limits adverse action over lawful, off-duty cannabis use, with exceptions.
- Main source: N.J.S.A. 24:6I-52.
- Federal testing rules (DOT and federal workplace programs) apply regardless of state law.
What the law protects
- As enacted in P.L.2021, c.16, § 48, an employer may not refuse to hire or employ, discharge, or take adverse action against a person because the person does or does not use cannabis items.
- An employee may not be subject to adverse action solely because cannabinoid metabolites are present in their bodily fluid from conduct permitted by the state’s adult-use law.
Exceptions and limits
- Employers may keep a drug- and alcohol-free workplace and prohibit use, possession, or being under the influence during work hours.
- If the law results in a provable adverse impact on an employer subject to a federal contract, that employer may revise its employee prohibitions consistent with federal law.
Drug testing rules
- Employers may test on reasonable suspicion, on observable signs of intoxication, after a work-related accident, randomly, as part of pre-employment screening, or as regular screening (N.J.S.A. 24:6I-52).
- The drug test must include scientifically reliable objective testing methods (such as blood, urine, or saliva testing) and a physical evaluation of impairment by a certified individual — the law calls this certification a Workplace Impairment Recognition Expert.
Notes and history
- This summary is based on the law as enacted in 2021. It may have been amended or supplemented by regulations since; check the current statute before relying on it.
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 Jersey?
New Jersey law (N.J.S.A. 24:6I-52) limits adverse action over lawful off-duty cannabis use, but it has exceptions — including impairment or use at work, federally regulated or funded jobs, and specific positions listed in the statute. It is not a blanket protection.
Can New Jersey employers still drug test for THC?
Testing is limited in some situations but not banned outright. Read the testing section above for what N.J.S.A. 24:6I-52 allows, and remember that federally required tests (for example DOT-regulated jobs) are unaffected.
Does New Jersey 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.
