How Much Is an Ounce of Cannabis? The Short Answer
An ounce of cannabis is 28 grams. In legal US markets, the retail price for an ounce of flower typically falls between about $100 and $400. That range is wide because price depends on where you buy, what tier of flower you choose, and the taxes added at checkout. In mature markets with heavy supply, such as Oregon or Washington, budget ounces can sell for under $150. In markets with limited competition or high taxes, such as Illinois, top-shelf ounces often exceed $350. Before you buy, confirm the weight, the license status of the seller, and the total cost after tax.
Medical Cannabis Prices vs Recreational: A Buying Guide
What to Look For When Buying an Ounce
- Weight: An ounce is 28 grams. A half ounce is 14 grams. A quarter is 7 grams. An eighth is 3.5 grams. Ask for a receipt that lists the weight.
- Tier: Dispensaries usually sort flower into budget, mid-tier, and premium. Budget often means smaller buds or older harvest. Premium means hand-trimmed, dense buds with strong aroma.
- Harvest date: Fresh flower keeps terpenes. Older flower loses smell and potency. Look for a harvest or package date within the last few months.
- Lab testing: Legal products carry a label with THC and CBD percentages, plus test results for mold, pesticides, and heavy metals. If the label is missing, walk away.
- Taxes and fees: The sticker price is not the final price. State and local cannabis taxes can add 20% to 40% or more. Delivery fees and card fees also apply.

Common Pitfalls
- Buying from unlicensed sellers: No testing, no weight guarantee, and no legal recourse. Licensed shops follow state lab rules.
- Assuming higher THC means better value: A 30% THC flower can cost more than a 22% flower, but effects depend on terpenes and your own response.
- Ignoring the final price: Taxes can turn a $200 ounce into a $260 purchase. Ask for the out-the-door total.
- Short weights: Some illegal sellers short the bag. A kitchen scale is cheap insurance. Legal dispensaries are audited, but mistakes happen.
- Old inventory: Flower that sits for a year loses smell and potency. Check the date.
FAQ
How many grams are in an ounce of cannabis?
28 grams. That is the standard in the US and most legal markets.
Why Are Cannabis Prices High at Dispensaries?
What is a zip?
Zip is slang for an ounce, short for "oz." It means 28 grams.
Why is an ounce cheaper per gram than an eighth?
Volume pricing. Packaging, labeling, and labor costs are spread across more product, so the per-gram price drops as the weight goes up.
Can I buy an ounce at one time legally?
Many legal states set the purchase limit at one ounce of flower per transaction. Some allow more for medical patients. Check your state's rules before you shop.
Does an ounce of shake cost the same as an ounce of flower?
No. Shake and trim usually cost less because they contain fewer intact buds and lower potency. They work for pre-rolls or extraction, but not for a premium smoking experience.
