Drug DUI in New Jersey
Marijuana & Prescription Drug Charges
If you’ve been charged with a drug DUI in New Jersey, you may be wondering what the law says and how it applies to your situation. Convictions can result in harsh penalties. With the proper defense, you may be able to protect your license, avoid jail time, and reduce long-term consequences.
This page explains the law, penalties, and defense options for marijuana DUIs, prescription drug DUIs, and over-the-counter drug cases in NJ.
What Is a DUID in NJ?
Under N.J.S.A. 39:4-50, a drug DUI (DUID) applies when a driver operates a motor vehicle while impaired by:
- Marijuana
- Prescription medications
- Over-the-counter drugs
- Illicit or controlled substances
Marijuana DUI in NJ: Legalization & Impairment Laws
- Recreational marijuana became legal in New Jersey in 2021.
- A medical marijuana card does not prevent prosecution if police believe you are impaired.
- There is no per se THC limit under New Jersey law.
- Even lawful possession of marijuana in a vehicle can result in separate charges, particularly for open containers.
- A 2012 bill attempted to legalize recreational marijuana but failed. Recreational use was not legalized until 2021.
Legal Marijuana Does Not Mean Legal Driving
- Recreational marijuana is legal in New Jersey, but driving while impaired is not.
- Possession of marijuana in a vehicle, especially in an open container, can still lead to charges.
- Even medical marijuana cardholders can face a DUID if police believe their ability to drive was affected.
Prescription Drug DUI in New Jersey & OTC Medications
Certain medications, even if prescribed or legally purchased, can still cause impairment:
- Prescription drugs: opioids, benzodiazepines, antidepressants, sleep aids
- Over-the-counter drugs: antihistamines, cough syrup, Nyquil-type products
Key point: You can be charged with a DUI in NJ even if you took medication precisely as prescribed, if it impaired your ability to drive safely.
How Police Prove DUID In New Jersey
Police may rely on several forms of evidence:
- Observations of driving behavior and physical signs of impairment
- Field sobriety tests
- Drug Recognition Evaluator (DRE) assessments — In 2023, the NJ Supreme Court limited DRE testimony: officers may only say a driver’s behavior was consistent with impairment, not caused by drugs, and only if toxicology was reasonably attempted
- Chemical tests (blood and urine) require a warrant or consent. Results can be unreliable due to differences in how the body metabolizes drugs, the time delay between driving and testing, and potential chain of custody issues. Unlike alcohol breath tests, New Jersey’s implied consent law does not apply.

DUID Enforcement at DWI Checkpoints
- DWI checkpoints are used to identify impaired drivers
- While aimed mainly at alcohol, they are also used for drug impairment.
- Officers may note odors, slurred speech, abnormal eye movements, and other signs.
- Lawful checkpoints must follow:
- Advance public notice
- Neutral stopping formula
- Clear safety signage
- If these conditions are missing, defense attorneys may challenge the stop.

Additional Laws to Know
- N.J.S.A. 2C:35-10: Drug possession and penalties near schools. Possession or use of drugs within 1,000 feet of school property can bring enhanced fines, mandatory community service, and possible jail time.
- School Zone DWI Repeal (2019): The law enhancing penalties for DWI within 1,000 feet of a school was repealed. However, possession laws near schools remain in effect.
- Commercial Drivers (CDL): CDL drivers face federal disqualifications under 49 C.F.R. § 383.51, even for DUIs in personal vehicles.
- Marijuana Odor & Searches: Since legalization, odor alone is not always enough to justify a full vehicle search, though it may still be a factor.
School Zone Laws in New Jersey
- The School Zone DWI law was repealed in 2019. Driving under the influence within 1,000 feet of a school no longer carries automatic enhanced penalties.
- Drug possession near a school is still a crime under N.J.S.A. 2C:35-10. If drugs are found within 1,000 feet of school property, penalties may include added fines, community service, and possible jail time.
- This means a driver could face both a drug DUI and school zone possession charges in the same case.
New Jersey DUID (Drug DWI) FAQ
FAQs on Marijuana, Prescription Drugs, Penalties & CDL And Charges
If you’ve been arrested or are worried about a drug DUI in New Jersey, you probably have questions about what the law allows, how police prove impairment, and what penalties you could face. Below are answers to the most common questions people ask about marijuana DUIs, prescription drug DUIs, DUID penalties in NJ, and CDL consequences.
General DUID Questions
Can I get a DUI if marijuana is legal in New Jersey?
Yes. Marijuana may be legal to use recreationally and medicinally, but it is still illegal to drive if it impairs your ability to operate a vehicle safely.
Is there a legal THC limit in New Jersey?
No. Unlike alcohol, New Jersey has no set THC limit. Prosecutors rely on officer observations, field tests, and toxicology results to argue impairment.
Does having a medical marijuana card protect me from a DUI?
No. A valid card does not shield you from a DUI if police believe you were impaired.
Is there a difference in penalties for marijuana vs. prescription drugs?
No. DUID penalties in NJ are similar regardless of whether the substance was marijuana, a prescription medication, or an over-the-counter drug.
What are the long-term consequences of a drug DUI conviction?
A conviction can increase insurance costs, limit job opportunities, and impact professional licenses. It also remains on your driving record.
Can a DUID conviction be expunged in New Jersey?
No. A DUID is a traffic offense and cannot be expunged under current New Jersey law.
Prescription & Over-the-Counter Medications
Can over-the-counter medications like NyQuil lead to a DUI?
Yes. If a cold medicine or sleep aid makes you drowsy or affects coordination, you can be charged with impaired driving.
Can I be charged with DUI for prescription medications if I have a valid prescription?
Yes. Even if legally prescribed, you may face charges if the drug impairs your ability to drive safely.
Which prescriptions most often lead to DUI stops?
Common examples include:
Opioids (e.g., oxycodone)
Benzodiazepines (e.g., Xanax/Alprazolam)
Sleep aids (e.g., Ambien/Zolpidem)
Certain antihistamines (e.g., Benadryl/Diphenhydramine)
Police Stops, Testing & Checkpoints
How do police determine drug impairment?
Through driving observations, field sobriety tests, Drug Recognition Evaluator (DRE) assessments, and blood or urine chemical testing.
Do I have to take a drug test if I’m pulled over?
No. The implied consent law applies to alcohol breath tests, not drug, blood, or urine tests.
Can I refuse a blood or urine test in NJ?
Yes. Refusal does not carry the same penalties as refusing a breath test, though police may obtain a warrant for testing.
Are sobriety checkpoints legal in New Jersey?
Yes. They are legal if conducted properly with advance notice, neutral stopping patterns, and clear safety measures.
Can you be arrested for DUID at a sobriety checkpoint?
Yes. If officers see signs of drug impairment, you may be detained and charged.
Marijuana, Vehicles & Searches
Can police search my car if they smell marijuana?
Not always. Odor alone is not always enough to justify a full search, but it can contribute.
Can I keep marijuana in my car if it’s legal in NJ?
You cannot keep it in an open container within the driver’s reach. It should be stored in the trunk or another sealed area.
Did New Jersey legalize marijuana in 2012?
No. A bill was proposed in 2012, but failed. Recreational marijuana was not legalized until 2021.
What happened to the School Zone DWI in New Jersey?
The law that enhanced DWI penalties within 1,000 feet of a school was repealed in 2019. However, possession near schools is still treated as a separate offense.
Penalties & Alternatives

Yes. Alternatives may include treatment programs, community service, or placement in Recovery Court when drug charges are also involved.
How long does marijuana stay in your system for DUI purposes?
It can remain detectable in urine or blood for days or even weeks, but detection does not always mean you were impaired while driving.
Appeals & CDL Consequences
Can I appeal a DUID conviction in New Jersey?

How long do I have to appeal a DUID conviction in NJ?
Generally, you have 20 days to file an appeal in municipal court.
