New Jersey Marijuana Testing Laws Could Change for Construction Workers and First Responders
A pending New Jersey Senate bill would create a significant carve-out from the state's recreational cannabis employment protections — allowing certain employers to test for and act on THC use, including off-duty use, for workers in safety-sensitive roles. Here is what employers need to know before it moves forward.
Quick Answer
New Jersey Senate Bill S4685, introduced October 1, 2026, would allow employers to prohibit recreational marijuana use — including off-duty use — for four categories of safety-sensitive workers: law enforcement officers, first responders, commercial drivers, and heavy equipment operators. Under the proposal, employers in these sectors could conduct random THC drug testing and take disciplinary action based on a positive result without needing to demonstrate workplace impairment. The bill has not passed. It remains in committee, and current New Jersey employment protections still apply. This is a proposal to watch — not a law to act on yet.
What Senate Bill S4685 Would Do
New Jersey legalized adult recreational cannabis use in 2021, and the state's Cannabis Regulatory, Enforcement Assistance, and Marketplace Modernization Act — commonly called CREAMMA — includes strong employment protections. Under current law, most New Jersey employers cannot take adverse employment action against an employee solely because they use cannabis lawfully off-duty, or because a drug test returns positive for cannabinoid metabolites. The standard for adverse action is demonstrable on-the-job impairment — observable symptoms, not a test result alone.
Senate Bill S4685 would create a targeted exception to that framework. As analyzed by Morgan Lewis in an October 30, 2026 legal publication, the bill would permit employers to prohibit recreational cannabis use — on and off duty — for employees in these four occupational categories:
- Law enforcement officers
- First responders (including emergency medical technicians and firefighters)
- Commercial drivers
- Heavy equipment operators
For workers in these roles, employers would be authorized to conduct random THC drug testing and to impose discipline — including termination — based on a positive test result, even without documented evidence that the employee was impaired while on duty. The bill expressly references urine, saliva, and blood as permitted testing methods, per the official New Jersey Legislature text of S4685.
⚠ Status as of October 2026: S4685 has been referred to the Senate Law and Public Safety Committee. It has not passed either chamber and is not yet law. New Jersey employers should not change their existing drug testing policies based on this proposal until and unless it is enacted. Consult qualified employment counsel before making any policy changes.
Current Law vs. Proposed S4685: Side-by-Side for New Jersey Employers
Why Construction and Transportation Employers Are Watching This Closely
New Jersey's construction sector and transportation industry have some of the most direct exposure to the question this bill is trying to answer. Heavy equipment operators — crane operators, excavator and bulldozer operators, forklift operators on active job sites — are the category where a THC-impaired worker creates the most immediate physical risk to coworkers and the public. Under current New Jersey law, a construction employer who conducts a random drug test and receives a positive THC result is in a difficult position: the result alone may not support adverse action, and proving impairment at the time of the test is operationally complex.
Commercial drivers, particularly those operating under CDL requirements, are already subject to federal DOT drug testing rules that preempt state cannabis protections. But non-CDL commercial driving and intrastate transportation operations in New Jersey sit in a gap where state law currently limits what employers can do with a positive THC result. S4685 would close that gap for covered roles.
The New York comparison: The contrast with neighboring New York is striking. A New York State Trooper terminated after two positive THC tests is currently suing to get his job back — a case that illustrates how difficult it is to act on a positive THC result under states with strong off-duty cannabis protections. For a full breakdown of that case and what it means for employer drug testing programs, see our analysis of the New York trooper THC firing and what employers can learn from it. New Jersey S4685 is, in part, a legislative response to exactly the kind of enforcement gap that case exposes.
What Drug Testing Methods Would Apply Under S4685
The bill's express reference to urine, saliva, and blood as permitted testing methods is notable. It signals that the New Jersey Legislature is aware of the detection window debate — the well-documented fact that urine THC tests detect metabolites that can remain detectable for days to weeks after impairment has resolved — and is not limiting covered employers to any single collection method.
For New Jersey construction companies, first-responder agencies, and transportation employers preparing for a possible legal change, the practical implication is that oral fluid saliva testing may become a preferred collection method for random programs in covered roles. Oral fluid tests detect recent use — typically within 6 to 48 hours — and align the test result more directly with potential on-the-job impairment. Oral fluid saliva drug test kits are available from DrugScreens.com in employment, insurance, and forensic use classifications, including SAFElife saliva drug test kits and the Healgen saliva drug test kit lineup.
For programs that prefer urine collection — the established standard for most non-DOT workplace programs — CLIA-waived urine drug test cups remain the most widely used format. The SAFElife urine drug test cup collection and SAFElife dip card tests are available in multi-panel configurations for construction, transportation, and safety-sensitive employer programs across the region.
What New Jersey Employers Should Do Now
Because S4685 has not passed, the right move for most New Jersey employers right now is to monitor — not to act. Current CREAMMA protections remain in effect. Changing your drug testing policy based on a pending bill that has not cleared committee would be premature and could expose your organization to the same legal risk you are trying to avoid.
That said, employers in the four covered categories — law enforcement agencies, first-responder organizations, commercial carriers, and construction companies with heavy equipment operations — have a specific reason to begin reviewing their written drug-free workplace policies now, so they are positioned to update them quickly if S4685 moves forward. Key preparation steps include:
- Identifying which positions in your workforce would fall into the four covered categories under the bill's language
- Reviewing your current written drug testing policy to understand how it addresses THC and off-duty cannabis use
- Consulting with employment counsel about how S4685 would interact with any medical cannabis accommodations your organization currently makes
- Evaluating whether your current drug test supply configuration — panel count, collection method, THC vs. non-THC — remains appropriate for your workforce and your risk profile under either the current law or the proposed framework
✓ For employers evaluating non-THC panel options: Some New Jersey employers outside the four covered categories are already moving toward drug test supplies without THC for pre-employment and random programs — screening for cocaine, methamphetamine, opiates, and benzodiazepines without creating a paper trail of THC positives that current law limits their ability to act on. This approach sidesteps the off-duty use liability while maintaining meaningful substance abuse detection for the drugs most commonly associated with on-the-job impairment risk.
