New Jersey Cannabis Law: Possession, Use, and Home Growing

New Jersey cannabis laws let adults 21 and older possess up to six ounces of cannabis, buy it from licensed dispensaries, and use it in private under the Cannabis Regulatory, Enforcement Assistance, and Marketplace Modernization Act (the CREAMM Act). Home growing is not allowed, public use is restricted, and impaired driving is treated like drunk driving. Cannabis also remains illegal under federal law, which still matters in specific places and situations.

Who Can Possess Cannabis, and How Much

Anyone 21 or older can legally possess up to six ounces of cannabis and cannabis products at any given time.¹ The CREAMM Act protects possession of up to one ounce (28.35 grams) of usable flower or five grams of cannabis resin during any single interaction with law enforcement.² The Cannabis Regulatory Commission sets equivalency calculations for edibles, concentrates, and other forms.

Cross the six-ounce line and the consequences climb quickly. Possessing more than six ounces of marijuana or more than 17 grams of hashish is a fourth-degree crime carrying up to 18 months in prison and fines up to $25,000.³ Larger quantities are prosecuted as manufacturing or distribution under a separate statute.⁴

Buying From Licensed Dispensaries

All legal recreational cannabis has to come from a dispensary licensed by the Cannabis Regulatory Commission.⁵ Bring a valid government-issued photo ID showing you are at least 21. Retailers check identification on every purchase.

A single transaction is capped at one ounce of usable cannabis, even though you can hold six ounces total. That one-ounce cap translates differently depending on the product:

Dried flower: 28.35 grams (one ounce)
Solid concentrates or resin: 4 grams
Liquid concentrates: the equivalent of 4 grams in solution
Vaporized formulations: 4 grams of oil

Point-of-sale systems track these limits at the register.¹ Not every town has a dispensary. Many municipalities have used the CREAMM Act’s opt-out provision to prohibit cannabis businesses within their borders.

Delivery

Licensed delivery services can bring cannabis to your home. The driver has to inspect your photo ID and confirm you are at least 21 before handing anything over. Acceptable ID includes a driver’s license from any state, a U.S. passport, a foreign passport valid for U.S. use, or any government-issued photo ID with your date of birth.⁶ Delivery personnel log the age verification, and the service keeps those records available for CRC inspection.

Where You Can Use Cannabis

Use is generally confined to private residences where you have the right to be there. Smoking or vaping cannabis is prohibited in the same indoor public places where tobacco is banned: restaurants, bars, offices, public transportation. Many outdoor public spaces, including parks and sidewalks, are also off-limits, and local governments can impose stricter rules.

Landlords can bar smoking and vaping through lease provisions, and breaking those terms can support eviction. Hotels are allowed to designate up to 20% of their rooms as smoking rooms, but that does not mean cannabis is welcome. Most hotels treat cannabis differently from tobacco, so unauthorized use can lead to cleaning fees or removal. Ask before you consume.

Home Cultivation Is Illegal

New Jersey does not permit recreational or medical users to grow cannabis at home. The CRC has no authority to authorize private residential cultivation.⁷ This is where New Jersey diverges from many other legal states, and where people most often misread the law.

Growing even a few plants without a state cultivation license is prosecuted as manufacturing. A harvest of more than one ounce but less than five pounds is a third-degree crime carrying three to five years in prison and fines up to $25,000.⁴ Ten or more plants is a second-degree crime regardless of weight. Fifty or more plants moves into first-degree territory with potential fines up to $300,000.

Driving and Transporting Cannabis

You can transport cannabis you legally purchased, but it has to stay sealed and out of reach while the car is moving. New Jersey’s open-container law covers cannabis alongside alcohol: no occupant of a vehicle on a public road may possess any unsealed cannabis item intended for smoking, vaping, or aerosolizing.⁸ If the seal is broken, the product goes in the trunk, or behind the last upright seat if the vehicle has no trunk. A first violation is a $200 fine; a second is $250 or 10 days of community service.

Driving While Impaired

Driving impaired by cannabis is handled under the same DUI statute as alcohol. A first drug-related DUI carries a fine of $300 to $500, up to 30 days in jail, and a license suspension of seven months to one year.⁹ On top of those, you owe a $230 Intoxicated Driver Resource Center fee, $100 to the drunk driving fund, $100 to the Alcohol Education, Rehabilitation and Enforcement Fund, a $75 Neighborhood Services Fund fee, and a $1,000-per-year insurance surcharge for three years.

New Jersey’s implied consent law applies to cannabis stops. Refusing testing after a DUI arrest brings a separate $300 to $500 fine for a first refusal, plus an ignition interlock requirement before your license is restored.¹⁰ Second and third refusals add years of license forfeiture on top of the interlock.

Job Protections and Drug Testing

The CREAMM Act separates what you do off the clock from what your employer can penalize. An employer cannot refuse to hire, fire, or otherwise discipline you solely because a drug test finds cannabis metabolites in your system.¹¹ Metabolites can linger for weeks, and their presence alone does not prove current impairment.

The law created a certified role called the Workplace Impairment Recognition Expert (WIRE) to assess whether an employee is actually impaired on the job. A positive test by itself is not sufficient for adverse action; a WIRE has to physically evaluate the employee and observe signs of active impairment first.¹²

Employers can still keep drug-free workplace policies, test after accidents, and test on reasonable suspicion of on-the-job impairment. Certain jobs are carved out entirely, and workers in these categories can be prohibited from cannabis use even off duty:

Employees covered by the federal Omnibus Transportation Employee Testing Act
Railroad workers subject to the Railway Labor Act
Law enforcement officers whose duties require carrying a firearm
Public utility employees regulated by the Board of Public Utilities
Positions at critical infrastructure facilities where the CRC agrees the risk is exceptionally high¹¹

Taxes at the Register

Retail cannabis is subject to New Jersey’s 6.625% sales tax. A Social Equity Excise Fee also applies at the cultivator level and is passed through to consumers; as of January 1, 2026, it is $2.50 per ounce of cannabis sold by a licensed cultivator.¹³ Municipalities that allow cannabis businesses can add a local transfer tax on retail sales of up to 2%. Not every town charges the maximum, and some charge nothing.

Federal Law Still Matters

Cannabis is a Schedule I controlled substance under federal law, and state legalization does not change that. A few practical consequences follow. Carrying cannabis onto federal property, including post offices, national parks, military bases, and federal courthouses, can result in federal charges no matter what New Jersey allows. Crossing state lines with any cannabis product violates federal law, even into another legal state.

Federal illegality also reaches banking, housing, and immigration. Most banks operate under federal charters and remain cautious about cannabis-related accounts. Federally subsidized housing can prohibit cannabis use as a lease condition. For non-citizens, any cannabis involvement, even in a legal state, can create immigration consequences ranging from visa denial to deportation.

Medical Cannabis Works Differently

New Jersey also runs a medical program under the Jake Honig Compassionate Use Medical Cannabis Act. Registered patients can obtain up to 85 grams every 30 days from licensed Alternative Treatment Centers, and qualifying conditions include chronic pain, anxiety, PTSD, cancer, epilepsy, multiple sclerosis, migraines, inflammatory bowel disease, and opioid use disorder, among others.¹⁴ Medical patients carry a program-issued ID card and follow most of the same consumption, transport, and no-home-grow rules as recreational users. The practical benefits are a higher purchase allowance and exemption from certain taxes.

Past Convictions and Expungement

New Jersey’s Marijuana Decriminalization Law, effective July 1, 2021, ordered automatic expungement of certain marijuana and hashish cases. The New Jersey Supreme Court directed thousands of cases to be cleared without requiring individuals to file petitions.¹⁵

Automatic expungement applied where the only conviction was for one of these offenses:

Possession of marijuana (over 50 grams) or hashish (over 5 grams)
Possession of 50 grams or less of marijuana, or 5 grams or less of hashish
Distribution of less than one ounce of marijuana or less than 5 grams of hashish

Cases combining one of those offenses with a related charge, such as drug paraphernalia possession, being under the influence, or failure to dispose of a controlled substance, were also expunged. If you believe your case qualified but was not cleared, you can file a motion for judicial review with the court that handled the original charges.¹⁵ The Cannabis Regulatory Commission also publishes instructions for requesting a certification of expungement, which involves submitting a form to the court where the charges originated.¹⁶
