Recreational cannabis has been legal in New Jersey since 2021, and dispensaries are now a familiar sight across South Jersey. That has led many people to assume that marijuana can no longer get them into legal trouble. That isn’t the case. NJ marijuana laws still draw clear lines around age, amount, driving and where cannabis can be used, and crossing them can lead to charges. Here’s a practical look at what’s allowed and where the risks remain.

Key Takeaways

• Adults 21 and older can legally buy cannabis from licensed dispensaries and possess up to 6 ounces.
• Adults can gift up to 1 ounce to another adult 21 or older, but selling without a license is still illegal.
• Driving while impaired by cannabis is treated like any other impaired driving case.
• Taking cannabis across state lines is still illegal, even into another state where it’s legal.
• Possessing more than 6 ounces, unlicensed sales and home growing for recreational use can still lead to criminal charges.

What Do NJ Marijuana Laws Allow?

Adults 21 and older can legally purchase cannabis from licensed dispensaries and possess up to 6 ounces. According to the New Jersey Cannabis Regulatory Commission, adults may also gift up to 1 ounce to another adult 21 or older, and cannabis can generally be smoked where cigarette smoking is allowed unless a property owner or other rule says otherwise.

Those rules give adults real freedom, but they also come with limits that matter when police get involved.

What Is Still Illegal Under NJ Marijuana Laws?

Legalization didn’t remove every cannabis-related offense. Activities that can still lead to charges or penalties include:

• Driving while impaired by cannabis: New Jersey’s impaired driving laws apply to cannabis just as they do to alcohol.
• Crossing state lines: Transporting cannabis into or out of New Jersey remains illegal, including trips to neighboring states such as Pennsylvania.
• Unlicensed sales: Selling cannabis without a state license is still a criminal matter, and gifting larger amounts or “gifting” as part of a sale can draw scrutiny.
• Possessing more than the legal limit: Possessing more than 6 ounces is a fourth-degree crime, and larger amounts can lead to distribution charges.
• Growing at home for recreational use: Home cultivation is not permitted for recreational users.
• Use on federal property: Cannabis remains illegal under federal law, which applies on federal land and in federal buildings.

Can You Get a DWI for Marijuana in New Jersey?

Yes. A driver who is impaired by cannabis can be charged with DWI under the same law that covers alcohol. Unlike alcohol cases, there’s no simple breath test number for cannabis, so these cases often rely on officer observations, field sobriety testing and evaluations by specially trained officers.

That reliance on observation can leave room for a strong defense. Our DUI and DWI defense work includes challenging the basis for the stop, the officer’s conclusions and the reliability of any testing.

What Happens if Someone Under 21 Is Caught With Cannabis?

Underage possession is still prohibited. For a first violation, police generally seize the cannabis and issue a written warning rather than making an arrest, and parents may be notified when the person is a minor. But the situation can change quickly when other allegations are involved, such as driving, distribution or school-related incidents.

Can Police Still Search Your Car Over Marijuana?

New Jersey changed the rules here too. The odor of cannabis, burnt or raw, by itself is no longer enough to justify stopping or searching someone. There is an important exception: if an officer has other evidence that a driver is impaired, an arrest and a vehicle search may follow. Police still need a lawful basis for any search, and when they cross that line, evidence may be challenged and potentially suppressed.
