Cannabis rules in New Brunswick
In New Brunswick you have to be 19 to buy, possess, grow or use cannabis. You can't consume it in public: the law limits use to your home, your own property or an occupied campsite. Adults can grow up to four plants, and legal cannabis is sold by Cannabis NB, its online store and a small number of certified private stores.
What is the legal age for cannabis in New Brunswick?
The legal age is 19 to buy, possess, consume or grow cannabis. Stores and the Cannabis NB website are 19 and over only, and stores accept a provincial driver's licence, a Canadian military ID or a passport as proof of age.
Provincial rules come from New Brunswick's Cannabis Control Act, which sits on top of the federal Cannabis Act. This is general information; the law is what counts.
How much cannabis can you carry in New Brunswick?
Outside your home, adults can carry up to 30 grams of dried cannabis or the equivalent, the federal limit. The province sets no cap on how much you can keep at home.
What it does set is a storage rule: cannabis kept in a home has to be in a secure space that people under 19 can't get to. Cannabis NB also limits each order to 30 grams of dried flower equivalent.
Where can you smoke weed in New Brunswick?
Not in public. New Brunswick bans consuming cannabis in any form, smoking, vaping or eating, in any place the public can access. That rules out streets, sidewalks, parks, beaches and patios, even where tobacco smoking is allowed.
The province says you can consume cannabis in your home, in your backyard or on your property, and at an occupied campsite. In someone else's home you need the owner's permission. Tenants can use cannabis in their unit unless the lease specifically bans smoking or growing it, and an existing no-smoking clause already covers cannabis.
| Place | Allowed? |
|---|---|
| Your home, backyard or property | Allowed |
| Someone else's home | Allowed with the owner's permission |
| An occupied campsite | Allowed |
| A rental unit | Allowed unless the lease bans smoking or growing |
| Streets, sidewalks, parks, beaches | Not allowed |
| Bars, restaurants, patios | Not allowed |
| In or on any vehicle on a road or off-road trail, parked or moving | Not allowed |
Can you grow cannabis at home in New Brunswick?
Yes. Adults 19 and over can grow up to four plants per household, but New Brunswick adds security rules that most provinces don't. Plants grown indoors must be in a separate locked space, and plants grown outdoors must be surrounded by a locked enclosure at least 1.52 metres (5 feet) tall. You must also have obtained the seeds or plants legally.
Landlords can ban growing in a rental unit, so check your lease before you start.
How do you buy cannabis legally in New Brunswick?
Cannabis NB, a provincial Crown corporation, runs the legal market. According to its July 2026 figures it operates 32 stores, alongside 12 private retailers and 8 farmgate stores run by licensed producers, in more than 31 communities. Private retailers are certified by Cannabis NB and licensed by the province's Public Safety department; legal ones display a Cannabis NB badge with a QR code you can scan to confirm the store is on the approved list. You can browse legal stores on WeedDB.
Online orders go through cannabis-nb.com and ship only to New Brunswick addresses, not to post office boxes. Orders placed before 2:30 p.m. usually arrive the next business day. Whoever accepts the package must be 19 or older and show valid government photo ID, and it can be anyone 19+ living at that address. Same-day delivery is offered within 12 km of participating stores in the greater Moncton, Saint John, Rothesay, Fredericton and Oromocto areas.
Driving, travel and tips for visitors
You can't consume cannabis in or on a vehicle on a road or managed off-road trail, whether it's moving or not, and that applies to passengers. Under federal law, driving with 2 ng or more of THC per ml of blood within two hours of driving is a crime, with tougher penalties at 5 ng or more. New Brunswick also treats drug-impaired driving as an offence under its Motor Vehicle Act, and graduated licence holders must not use drugs at all while driving: a breach means a one-year suspension and starting the graduated licence over.
Visitors need to be 19 and carry photo ID. You can bring legally bought cannabis from another province within the 30 gram limit, but New Brunswick's rules apply once you arrive, which means no consuming in public, including at the beach or in a park. Never take cannabis across the US border or any international border, in either direction, even if it's legal where you're going. If you're shopping, our label guide helps you compare products.
