Cannabis laws in New Jersey have undergone significant changes in recent years, making it legal for both medical and recreational use. However, purchasing cannabis comes with specific legal requirements that every consumer must follow. Whether you are a first-time buyer or a seasoned user, understanding these regulations ensures that your experience remains within the boundaries of the law.
Legal Requirements for Buying Cannabis in NJ
At Citi Roots, a veteran-owned dispensary located near Princeton and Plainsboro, we take pride in offering high-quality cannabis products while adhering to New Jersey’s legal framework. Here’s everything you need to know before making a purchase.
Is Cannabis Legal in New Jersey?
Yes, cannabis is legal in New Jersey, but there are distinctions between medical and recreational use.
- Medical Cannabis: Legal since 2010 under the New Jersey Compassionate Use Medical Marijuana Act, allowing patients with qualifying conditions to purchase and use cannabis with a prescription.
- Recreational Cannabis: Legalized in November 2020 through a voter-approved referendum. The state officially allowed dispensaries to sell recreational cannabis in April 2022.
Even though it is legal, strict regulations govern the sale, possession, and consumption of cannabis.
Who Can Buy Cannabis in New Jersey?
1. Age Requirement
- Recreational cannabis buyers must be at least 21 years old.
- Medical marijuana patients can be under 21, but they need a doctor’s recommendation and must register with the state’s medical marijuana program.
2. Identification
To make a purchase, customers must present a valid, government-issued ID, such as:
- Driver’s license
- Passport
- State-issued ID card
For medical cannabis, patients must also provide their NJ Medical Marijuana Program (MMP) ID card.

How Much Cannabis Can You Buy?
New Jersey has strict purchase and possession limits:
- Recreational Users: Up to 1 ounce (28.35 grams) per transaction.
- Medical Patients: Up to 3 ounces within a 30-day period.
Possessing more than the legal limit can result in fines or legal consequences, so it’s essential to stay within these restrictions.
Where Can You Buy Legal Cannabis?
Cannabis can only be purchased from state-licensed dispensaries. Buying from unlicensed sellers or online sources that aren’t registered with the state is illegal and may result in criminal charges.
When choosing a dispensary, consider the following:
- Compliance with NJ laws
- Verified product quality and safety
- Knowledgeable staff to assist with selection
Citi Roots is fully licensed and follows all state regulations to ensure a safe and legal cannabis shopping experience.
Where Can You Consume Cannabis in NJ?
Even though cannabis is legal, its use is restricted to private property. Public consumption is prohibited, meaning you cannot use cannabis in:
- Parks
- Sidewalks
- Restaurants and bars
- Public transportation
- Federal property (even in NJ)
Landlords and employers also have the right to ban cannabis use on their premises. Before consuming, always check the policies of your residence or workplace.

Can You Drive After Using Cannabis?
No. Driving under the influence of cannabis is illegal in New Jersey and can result in severe penalties, including:
- License suspension
- Hefty fines
- Possible jail time
If you need to travel after consuming cannabis, consider using a rideshare service or having a designated driver.
Additionally, cannabis must be stored properly in a vehicle:
- It should be in a sealed container.
- It must be inaccessible to the driver (preferably in the trunk).
Bringing Cannabis Across State Lines
Transporting cannabis across state lines—even to a state where it is also legal—is a federal offense. Crossing into Pennsylvania or New York with cannabis purchased in NJ could result in serious legal consequences. It is best to consume your cannabis before leaving the state.
Workplace and Employment Regulations
New Jersey’s cannabis laws allow employers to prohibit cannabis use in the workplace. However, due to the New Jersey Cannabis Regulatory, Enforcement Assistance, and Marketplace Modernization Act (CREAMMA), employers cannot discriminate against employees solely for cannabis use outside of work.
What does this mean for workers?
- Employers can test for cannabis use, but termination requires a combination of test results and evidence of on-the-job impairment.
- Employees in safety-sensitive roles (e.g., transportation, healthcare) may have stricter regulations.
