How much is a half of weed? A half is half an ounce of cannabis, listed on dispensary menus as 14 grams. It sits between a quarter and a full ounce, and it suits adults who know what they like and want it to last. Here's what 14 grams looks like, how many joints it rolls, how it compares with other sizes and how it fits within Michigan law.
How much is a half of weed? 14 grams
An ounce weighs about 28.35 grams, and menus round it to 28 so the fractions come out clean. Converted, a half ounce of weed in grams comes to 14 on the menu, or about 14.17 by exact weight. That's also two quarters, or four eighths.
What 14 grams looks like
How much room a half takes up depends on the buds. Dense, tightly trimmed flower packs into a small container, while airy buds of the same weight can look like a lot more. Trust the scale, not your eyes: licensed packages list their net weight.
Slang for a half
- A half or a half O, short for half an ounce
- Half oz, the written shorthand
- Half zip, from "zip," older slang for an ounce
- Fourteen, for the grams
How many joints a half rolls
Researchers who analyzed more than 10,000 U.S. cannabis purchases estimated the average joint at about 0.31 to 0.32 grams. Other studies put typical joints at 0.3 to 0.5 grams.
| Joint size | Flower per joint | Joints from a half |
|---|---|---|
| Slim | 0.3 g | About 46 |
| Standard | 0.5 g | 28 |
| Large | 1 g | 14 |

Other common sizes and value per gram
| Size | Menu weight | How many make a half |
|---|---|---|
| Gram | 1 g | 14 |
| Eighth | 3.5 g | 4 |
| Quarter | 7 g | 2 |
| Ounce | 28 g | Half of one |
Divide the price by the grams to compare value. Bigger sizes usually cost less per gram, so a half can stretch your budget if you'll finish it while it's fresh. Still choosing a strain? An eighth or a quarter is a smaller commitment, and our cannabis measurements chart lines up every size.
What moves the price
Check your store's live menu for current prices. The main factors:
- Quality tier. Premium buds cost more than smalls or shake from the same harvest.
- Potency and strain. High-THC flower and sought-after strains tend to cost more.
- Retail taxes. Adult-use sales carry a 10% excise tax plus the 6% sales tax, which is figured on the price including the excise: about 16.6% together. Registered medical patients pay only the 6% sales tax.
- Wholesale tax. As of October 2026, a 24% wholesale tax, in effect since January 1, 2026, applies when growers and processors first sell adult-use cannabis to a retailer. It's not on your receipt, but it can be passed along.
- Deals. Promotions come and go, so check what's current before you buy.
Ways to use a half
- Rolling. Enough for a few dozen joints.
- Baking. Plenty for a batch of infused butter or oil. Decarboxylate the flower first and estimate the dose per serving before you bake.
- Spreading it out. For an occasional consumer, a half can last weeks or months in an airtight container away from heat and light.
Can you legally carry a half in Michigan?
Yes, if you're 21 or older:
| Situation | Michigan limit | A half is |
|---|---|---|
| Carrying it | 2.5 ounces, with a 15-gram cap on concentrate | One-fifth of the limit |
| Buying at a licensed adult-use store | 2.5 ounces per transaction | Well under |
| Keeping it at home | 10 ounces plus your own plants' harvest; past 2.5 ounces, keep it locked | Well under |
- Bring ID. Michigan stores check government-issued photo ID before every sale.
- In the car. No using cannabis while driving, and no smoking in a vehicle's passenger area on a public road. Sealed and out of reach, such as in the trunk, is the cautious habit.
- Stay in state. Don't travel across state lines with cannabis.
