"Average" is the least useful word in cannabis retail. A state average blends $3 grams from a busted outdoor harvest with $18 grams of hand-trimmed indoor, then adds a tax picture that changes from one city to the next. So before you compare two states, decide what you're actually buying: a mid-shelf gram, a high-THC eighth, a vape cart, or an ounce of flower. The number moves a lot depending on that answer.
Start with out-the-door price, not menu price
Menu prices are bait. In Illinois, a 30% THC flower purchase can carry a 25% excise on top of local and sales taxes. In Washington, the 37% excise is baked into the sticker at many shops. In California you add 15% excise plus sales tax at the register. Two states can show the same $40 eighth and differ by $14 at checkout. That is the first parameter to pin down: is tax in or out?

Rough 2025 retail bands for a mid-shelf gram
These are typical recreational retail ranges for a single mid-grade flower gram, taxes excluded. They swing by city and by week, so treat them as a starting point rather than gospel.
Cannabis Price Per Ounce in California: A Buyer's Guide to Real Value
- Oregon: $4 to $7
- Washington: $5 to $8
- Colorado: $6 to $9
- Michigan: $6 to $9
- Arizona and Nevada: $8 to $11
- California: $8 to $12
- Maryland and Ohio: $9 to $12
- Florida (medical only): $8 to $11
- New York and Massachusetts: $10 to $14
- New Jersey, Connecticut, and Illinois: $12 to $16
Medical programs usually run 10% to 30% cheaper than the same state's recreational side. That gap comes mostly from lower tax, not from a lower list price.

The parameters that actually move the number
- License density. Oregon and Colorado have oversupply and many stores, so competition does the work. Illinois and New Jersey ran narrow license counts for years, and price reflects it.
- Form. Flower is the cheapest per milligram of THC. Vape carts cost more per gram, edibles more still per milligram. Concentrates sit in the middle per gram but hit harder.
- Tier. Most menus split flower into tiers by potency, trim, and brand. Tier 1 to Tier 3 can be a 2x gap inside one store.
- Distance from cultivation. Shops far from grow sites pay freight and pass it along.
- Season. Outdoor harvest lands in fall, and wholesale prices soften for months after.
Pitfalls I would avoid
- Comparing a medical gram to a recreational gram in the same state and calling it a price drop.
- Using a pre-roll price as a flower price. A 0.5g pre-roll at $9 works out to $18 per gram of flower, before you account for trim.
- Trusting a state average that folds in ounces, which sell at a steep per-gram discount.
- Ignoring delivery fees. Delivery adds $5 to $15 in most markets, plus a tip.
- Buying a cheap eighth without checking potency. A 14% eighth at $25 is worse value than a 24% eighth at $35.
How I would shop it
Pick three stores near you. Pull the same category at each, say 3.5g of 20%+ hybrid flower. Figure out-the-door cost per gram after tax, then compare. That is your real local average, and it beats any published state figure. Check a wholesale benchmark or state price index once a quarter to see which way the trend is running, then buy accordingly. If prices are sliding, buy smaller quantities more often and let the market keep dropping.
