Medical Cannabis Prices vs Recreational: A Buyer's Guide
Compare medical and recreational cannabis prices by tax, fees, potency caps, and limits so you pay the lowest cost per milligram.
An ounce of cannabis is 28 grams, and in U.S. legal markets it usually costs between $150 and $350 for flower. Budget and outdoor-grown ounces can sell for under $150, while top-shelf indoor flower from well-known brands often runs $400 or more. The final number depends on your state, the quality tier, THC and terpene content, taxes, and whether you buy from a licensed storefront or a licensed online menu with delivery.

What an Ounce Means in Cannabis Terms
An ounce is a weight, not a strain or a quality level. In the cannabis trade it is rounded to 28 grams, even though a true imperial ounce is 28.35 grams. You will also hear it called a "zip" or an "O" on dispensary menus.

- Eighth: 3.5 grams
- Quarter: 7 grams
- Half ounce: 14 grams
- Ounce: 28 grams
Because the unit is standard, price differences between two ounces almost always come down to quality, testing, and where you shop.
Typical Ounce Prices in the US
Prices swing a lot from state to state, and even between two shops in the same city. As a rough framework for flower:
- Budget or shake: $80 to $150. Often machine-trimmed, lower THC, or older harvests.
- Mid-tier flower: $150 to $250. Solid potency, common in mature markets.
- Premium flower: $250 to $400. Hand-trimmed, higher THC, recognizable brands.
- Top-shelf or craft: $400 and up. Small-batch grows, limited drops, high terpene content.
States with a long history of legal sales and heavy cultivation, such as California, Oregon, and Washington, tend to sit at the lower end. States with newer programs, limited license counts, or high excise taxes, such as Illinois and New York, often sit at the higher end. Concentrates, vapes, and pre-rolls are priced on their own scales and do not follow flower pricing.
What Drives the Price of an Ounce
- Grow method: Indoor flower costs more to produce than greenhouse or outdoor flower.
- Potency and testing: Lab-tested batches with documented THC, terpenes, and contaminant screening carry a premium.
- Trim and cure: Hand-trimmed, well-cured buds hold more bag appeal than machine-trimmed smalls.
- Taxes and fees: State excise taxes, sales tax, and local fees can add 15 to 35 percent at checkout.
- Supply and season: A glut after harvest pushes prices down; shortages push them up.
- Channel: Licensed retail, delivery, and medical menus each price differently.
Why Ounces Cost Less Per Gram
Buying in bulk lowers your cost per gram. A single gram might cost $12 to $20, an eighth might run $35 to $60, and a full ounce often lands near $5 to $12 per gram. The savings are real, but they only help if you can store the flower well and use it before it dries out. For occasional users, a half ounce or a few eighths often makes more sense than committing to 28 grams.
How to Compare Ounce Prices Before You Buy
- Check the THC percentage and total cannabinoid content, not just the strain name.
- Look for a harvest or packaging date. Fresher flower keeps its terpenes longer.
- Ask for the certificate of analysis (COA) from a licensed lab.
- Divide the listed price by 28 to get the per-gram cost, then add estimated taxes.
- Confirm the seller is a licensed retailer or delivery service in your state.
Reading the menu this way makes it easier to spot a genuine deal instead of a marked-up eighth in a larger jar.
Legal Notes for US Shoppers
Cannabis remains illegal under federal law in the United States, even where state programs allow adult or medical use. Rules on possession limits, home delivery, and where you can consume vary by state, and buyers generally must be 21 or older for adult-use products. Purchase from licensed operators in states where sales are legal, and check your own state's limits before ordering an ounce.
