An ounce of weed is 28 grams. A true ounce is about 28.35 grams, but the cannabis world rounds it to 28, and the smaller sizes break down from there: a half is 14 grams, a quarter is 7 and an eighth is 3.5. Saint John Bud Express sells flower in all of these sizes to customers across Saint John, so here is a plain guide to the numbers and when each size makes sense.
What are the common weed sizes?
- 1 gram: the smallest common size. Enough for a couple of joints, depending on how you roll.
- Eighth (1/8 oz): 3.5 grams. A popular size for trying a new strain.
- Quarter (1/4 oz): 7 grams. A good middle ground for regular smokers.
- Half (1/2 oz): 14 grams. Often called a "half" or "half O."
- Ounce (1 oz): 28 grams. Also called an "O" or a "zip."
Why is an ounce 28 grams and not 28.35?
Rounding for simplicity. An avoirdupois ounce is about 28.35 grams, but the cannabis market has long used 28 as the standard because it divides neatly into halves, quarters and eighths. When you buy an ounce, expect 28 grams.
How many joints are in an ounce?
It depends on how you roll. A typical joint uses somewhere between a third of a gram and a gram. That means an ounce could roll roughly 28 to 80 joints, depending on size.
Smaller joints stretch further. If you roll slim joints or smoke from a small bowl, an ounce lasts a long time.
How much does an ounce last?
It depends on your habits. Someone who smokes a joint a night might take a few weeks to get through an ounce. Someone who smokes a little on weekends could take months.
Freshness is the limit. Stored well, flower keeps for months, but it is at its best earlier on. If an ounce would take you a long time, store most of it sealed and fill a small daily jar. Our guide to storing weed covers how.
Why buy an ounce instead of smaller amounts?
Better value per gram. Larger sizes usually cost less per gram than eighths or grams. If you smoke regularly, an ounce often works out cheaper over time.
Fewer orders. One bigger order means less reordering through the week. Larger orders can also clear the free delivery line: delivery is $5, and free on orders over $100.
Room to roll, bake and share. Having more on hand makes it easier to roll for friends, make edibles at home or try different methods.
Budget ounces exist for a reason. Lots of everyday smokers buy budget or mid-grade ounces for daily use and save top-shelf flower for special occasions. Our cheap ounces guide walks through how to pick a good one.
When does a smaller size make more sense?
Trying something new. An eighth lets you test a strain before committing.
Variety. Several eighths of different strains can be more fun than one big bag of a single one.
Occasional use. If you only smoke now and then, smaller amounts stay fresher.
Premium flower. Top-shelf buds are often bought in smaller sizes to savour. See what AAAA means for how grades work.
How much can you carry?
Check the current provincial rules. Canada sets a public possession limit for dried cannabis that is measured in grams, and an ounce sits right around it. Rules can change, so check the latest before you travel with cannabis. Our guide to New Brunswick cannabis rules and ID has more, and you must be 19 or older to buy.
The Bottom Line
An ounce is 28 grams, which breaks down into two halves, four quarters or eight eighths. If you smoke regularly, an ounce usually gives you the best value per gram, while smaller sizes are better for trying new strains.
