If you’ve ever looked at a menu and wondered what an “eighth” actually is, you’re in good company. Cannabis is sold by weight, and the words can be confusing the first few times. Here’s a simple, no-jargon guide to the common sizes, what they weigh, and roughly what they cost in Massachusetts — so you can shop with confidence and get exactly what you need.

How Many Grams Are in an Eighth, Quarter, and Ounce?
The names all come from fractions of an ounce, which is where it gets a little math-y. Here’s the plain version:
- An eighth is 3.5 grams (an eighth of an ounce). It’s the most popular size and enough for several sessions for most people.
- A quarter is 7 grams — two eighths.
- A half is 14 grams.
- An ounce is 28 grams, which is also the most flower you’re allowed to buy at one time in Massachusetts.
How Much Does Weed Cost in Massachusetts?
Price comes down to a few things: the strain, the brand, the quality tier, and the format. Premium craft flower sits at the top of the range; house brands and daily deals sit lower. A couple of things worth knowing before you check out:
- Massachusetts adds cannabis tax at checkout (state and local, commonly around 20% total), so the shelf price isn’t quite the final price.
- Buying a little more at once usually lowers the price per gram — an ounce almost always costs less per gram than a single gram does.
- Bundles and daily deals are the easiest way to save. Take a look at our current specials and our $20 & under menu.
Which Size Should You Buy?
If you’re trying a strain for the first time, a gram or an eighth is a low-commitment way to see if you like it. Once you’ve found a favorite you keep coming back to, stepping up to a quarter, half, or ounce saves money over time.
One tip: buy what you’ll realistically use over the next few weeks. Flower is at its best fresh — store it somewhere cool, dark, and airtight to keep it that way.
Weights for Other Products
Flower isn’t the only thing measured by weight. Here’s how the other categories work:
- Pre-rolls are sold by the gram — usually 0.5g or 1g each, and often in multipacks. See our pre-rolls.
- Concentrates are potent, so they’re sold in small amounts. In Massachusetts you can buy up to 5 grams of concentrate at a time. Browse concentrates.
- Edibles are measured in milligrams (mg) of THC rather than grams. Massachusetts caps a single edible purchase at 500mg of THC.
Purchase limits can change, so if you’re buying in bulk it’s always worth confirming the current rules with the Massachusetts Cannabis Control Commission.
