1. The average cannabis product sold for $15.54

Headset’s September 2026 register data puts the average item price at $15.54, down 3.2% from $16.05 a year earlier. Figures are pre-tax and post-discount across 12 licensed U.S. markets.

2. The average dispensary basket was $44.74

Shoppers spent $44.74 per visit across 2.88 items on average in September 2026. Basket size matters as much as unit price when comparing “how much a run costs.”

3. Flower items averaged $23.92; vapor pens $22.02

By category, flower averaged $23.92 per item (−1.7% YoY) and vapor pens $22.02 (+1.5% YoY). Edibles averaged $10.50, pre-rolls $8.08, concentrates $17.73, and topicals $32.07.

4. A single gram of flower averaged $8.09

One-gram packages averaged $8.09 in September 2026. That is the expensive way to buy flower on a per-gram basis.

5. An eighth (3.5g) averaged $20.23 — $5.78 per gram

The standard eighth cost $20.23 ($5.78/g), down 0.5% year over year. Dispensaries in Headset’s 12 markets sold 10.3 million eighths in September 2026 alone.

6. Quarters, halves, and ounces keep dropping the per-gram rate

An ounce at $47.83 ($1.71/g) costs about one-fifth the per-gram rate of a single gram. Across all packaged sizes, flower equivalized to $3.56 per gram.

7. Vapor pens average about $22 per item

Headset’s category view shows vapor pens averaging about $22 across U.S. markets over the past year, matching the $22.02 September item price on the national prices page.

8. Cartridges ~$18; all-in-one disposables ~$28

In Headset’s vapor-pen mix, cartridges average about $18 and take roughly half of category dollars; all-in-one disposables average about $28 and take the other half. Hardware batteries sit outside that oil-product average.

9. Larger fills cost less per gram of oil

Headset’s equivalized view: roughly $46/g for half-gram, $20/g for full-gram, and $16/g for 2g formats. Buying more oil at once usually lowers unit cost — the same pattern as flower ounces.

10. Oregon eighths average $12.74; Ohio $29.54

State licensing and supply dominate price. Headset’s September 2026 packaged-eighth averages (full table):

That is a 2.3× spread inside one country: mature, high-supply Western markets at the bottom; newer limited-license Midwest and Mid-Atlantic markets at the top.

11. Packaged flower fell 3.8% per gram year over year

From September 2025 to September 2026, packaged flower moved from $3.70 to $3.56 per gram (−3.8%). Average item prices fell in seven of nine categories.

12. Discount rates rose from 23.6% to 27.1%

More of the shelf is given back at the register. Headset’s average discount rate rose from 23.6% to 27.1% over that year — more than a quarter of pre-discount shelf value.

13. What shoppers should take from the data

• Compare per gram, not sticker alone. Ounces and 1g–2g vape fills rewrite the unit math.
• Know your state’s lane. An “everyday” eighth in Oregon is priced like a deal in Ohio.
• Expect promotions. A 27% average discount rate means the register price often beats the menu board.
• Separate oil price from battery price. Vapor-pen averages exclude reusable hardware; proprietary pods (e.g. STIIIZY) need a matching battery on day one.

How much does an eighth of weed cost in 2026?

About $20.23 on average for a packaged 3.5g eighth in September 2026 across Headset’s 12 U.S. markets (pre-tax, post-discount). State averages range from $12.74 in Oregon to $29.54 in Ohio.

How much does a vape cart cost?

Headset’s vapor-pen data shows cartridges averaging about $18 and all-in-one disposables about $28, with the blended vapor-pen item near $22.

Are cannabis prices going down?

In per-gram terms, yes for flower: −3.8% year over year to $3.56/g, with discount rates up to 27.1%. Category item prices fell in most formats; vapor pens were a mild exception at +1.5% on item price in September 2026.

Why do weed prices differ so much by state?

Supply and licensing. Open-license, high-cultivation markets compress eighths toward the low teens; limited-license markets hold averages near $30, per Headset’s state table.
