Weed measurements explained: grams, eighths, ounces — and what they cost
A gram, an eighth, a quarter, an ounce — what each cannabis measurement means, how many joints it rolls, and the typical price range for each.

Dispensary flower menus are priced by weight, and the units come from an odd mix of metric and imperial: grams on the small end, fractions of an ounce above that. Here is the ladder, what each amount is actually good for, and what it typically costs in a licensed shop.
The ladder: gram to ounce
A gram (1 g) is the smallest amount most shops sell — enough for one to two joints. It is the right size for trying a new strain.
An eighth (3.5 g, one-eighth of an ounce) is the most popular purchase in America — roughly five to seven joints, or a week or two of light evening use. Most shelf prices you see quoted are eighth prices.
A quarter (7 g), half (14 g), and ounce (28 g) scale up from there. An ounce is the legal possession limit in many adult-use states, and per-gram pricing drops meaningfully as you buy larger sizes.
What flower typically costs
Prices vary a lot by state, taxes, and shelf tier, but broad licensed-market ranges look like this: grams around $5–15, eighths around $20–60, quarters around $40–110, and ounces around $80–300. Mature markets like Oklahoma, Oregon, and Michigan sit at the low end; newer or high-tax markets run higher.
Within one shop you will see budget, mid-shelf, and top-shelf tiers. The difference is genetics, growing method (indoor commands a premium), freshness, and brand — not safety; everything on a licensed shelf passed the same state testing.
Non-flower products price differently
Edibles are priced per package with the THC total on the label — a typical 100 mg package (ten 10 mg pieces) runs $10–25. Vape cartridges are priced by oil volume, usually $25–60 for a half-gram or full gram. Concentrates run $20–70 per gram depending on extraction type.
Comparing price-per-milligram of THC across product types is the budget shopper’s trick: edibles and concentrates usually deliver THC cheaper than flower, though the experience differs.
How to pay less
Shop deals first — daily specials, first-time customer discounts, and bundle pricing are everywhere in competitive markets. On Weedtip, the Deals page shows what is running near you today, and buying a size up almost always beats buying grams twice.
Frequently asked questions
How many joints does an eighth roll?
Five to seven average joints (about half a gram each), or three to four larger ones. Pre-rolls sold in shops are usually 0.5 g or 1 g each.
Why is dispensary weed more expensive than street prices?
Licensed products carry state testing, packaging, and cannabis taxes that can add 10–35%. In return you get lab-verified potency and contaminant screening, plus deals that often close most of the gap.
What is the biggest amount I can buy at once?
Most adult-use states cap purchases at one ounce of flower (sometimes more) per day, with separate limits for concentrates and edibles. The dispensary tracks this at checkout, so you cannot accidentally exceed it.
