The basic public possession rule

Adults of legal age in Alberta can carry up to 30 grams of dried cannabis or the equivalent in public. You can choose many formats, such as flower, pre-rolls, vapes, edibles, drinks, oils, capsules, topicals, and more. The key is to keep your total under the 30 g dried cannabis limit. At home you can store more, but when you leave your home the 30 g public rule applies.

What “dried cannabis equivalent” means

Not every product is sold as dried flower. To make the law simple, each package lists a number called the dried cannabis equivalence. This number tells you how many grams of dried cannabis that package counts toward your 30 g limit. You do not need to do math yourself. Just read the label and add up the equivalence numbers across all the items you carry.

For example, a small package of gummies might say “dried cannabis equivalence: 2 g.” A vape cart might show a different number. If you carry both, you add those numbers. If the total is 28 g you are under the limit. If the total is 32 g you are over and should remove an item before you leave home.

How to check your total quickly

1. Lay out your items. Keep unopened and opened packages together so you do not forget anything.
2. Find the equivalence line on each label. It is usually near the cannabinoid numbers, lot, and weight.
3. Write the numbers down. A small note in your phone works well.
4. Add them up. Stop once you reach 30. Remove something if you go over.

Most people carry far less than 30 g. If you are moving items between home and a friend’s place, it still pays to check the total, since multiple edibles and a vape can add up faster than you might expect.

Travel inside Canada

On domestic flights within Canada, the same 30 g dried cannabis equivalent rule applies to adults of legal age. Keep products in your carry-on if the airline allows it, and leave packages sealed when possible. Do not bring cannabis on international flights, even to countries where cannabis is legal. Different laws apply once you cross a border, and the penalties can be serious.

Cars, buses, and ride share

If you take a car, bus, or ride share, keep products sealed and out of reach of the driver. Do not open or use cannabis in a moving vehicle. If you are the driver, wait until another day to use cannabis. Impaired driving laws apply even when the product is legal. Plan your rides, book a taxi, or stay home if you plan to consume.

Buying vs carrying

Retail stores sell legal products in labeled, child-resistant packages. You can buy more than one item in a visit. The limit is about what you carry in public at a time, not about how many items you can purchase across the week. If you plan a large purchase for home storage, split the trip into two runs if your carry total would push beyond 30 g dried equivalent. The label makes this easy to track.

Storage at home

At home, store products in a cool, dark place. Keep them in child-resistant containers and out of reach of kids and pets. For flower, use airtight jars and avoid heat and sunlight. For edibles and drinks, keep to the best-before date on the package and follow any temperature guidance. A simple lockable box is a smart add-on if you live with family or roommates.

Events, parks, and private spaces

Rules about where you can use cannabis are set by local authorities and by property owners. Many public spaces do not allow consumption. Private homes and some outdoor areas do. Check posted signs or local websites before you open anything. The 30 g rule covers how much you carry, not where you can use it, so think of these as two separate checks: amount carried, and place rules.

Tips to stay on the right side of the rules

• Keep packages labeled. The label shows your equivalence and can help if anyone has questions.
• Carry only what you need. If you are going out for a few hours, a single package is often enough.
• Do not mix up opened items. Keep lids tight and avoid stray pieces in your pocket or bag.
• Plan your ride. Never drive after using cannabis. Book a cab, use transit, or walk with a friend.

FAQs

Does the 30 g limit apply to edibles and vapes?

Yes. Every product lists a dried cannabis equivalence number. Add those numbers together and keep the total at or below 30 g.

Do I need to weigh anything myself?

No. Use the number on the label. It already converts the product to dried cannabis equivalent.

Can I carry more than 30 g at home?

At home you can store more. The 30 g limit applies to public possession. Keep products stored safely.

Can I fly with cannabis?

Only on domestic flights within Canada and within the 30 g dried equivalent limit. Never take cannabis on international flights.

What happens if my package label is damaged?

Keep the receipt and avoid carrying large amounts in public. When in doubt, carry less and keep products sealed.

Bottom line

Read the equivalence line on each package and add the numbers. Stay at or below 30 g dried equivalent in public, keep items sealed, plan your transport, and you will be set for a smooth day.
