A cannabis cartridge price comparison chart is only useful when it compares cost per milligram of THC instead of the number printed on the box. A cheap half-gram cart and a pricier full-gram cart are not competing at the same scale, and normalizing the numbers often flips which one is actually the better buy. Once you chart price per milligram, most bargain carts stop looking like bargains.
Do the Math Before You Compare Anything
The core formula fits on one line: total price divided by total THC milligrams equals cost per milligram. Run it once and the rest of the chart falls into place.

Example: a half-gram cart with 400 mg of THC at $25 works out to about 6.3 cents per milligram. A full-gram cart with 800 mg of THC at $45 works out to about 5.6 cents per milligram. The second cart costs more at checkout and less per milligram, which is exactly the kind of thing a flat price list hides.
- Use the total THC number from the lab label, not the oil weight.
- Include tax in the price column or build a second column for out-the-door cost.
- Note the cartridge size in grams so you can sort by unit price.
Columns Your Chart Needs
- Product and brand name
- Oil type: distillate, cured resin, live resin, or rosin
- Cartridge size in grams
- Total THC in milligrams, plus CBD and minor cannabinoids if listed
- Price before tax and price after tax
- Cost per milligram of THC
- Hardware notes: ceramic vs. cotton wick, airflow, refillable or sealed
- Batch or test date
Typical Price Tiers
Prices shift with state taxes, licensing, and brand positioning, so treat these as buckets rather than fixed numbers.

- Value distillate. Usually the lowest cost per gram. THC is the main selling point, and terpenes are often added back after processing.
- Mid-tier resin. Cured and live resin carts sit in the middle. More plant-derived flavor and a wider cannabinoid profile than distillate.
- Premium rosin. Solventless and small-batch carts land at the top of the chart, with the shortest supply and the fewest hardware options.
- Multi-packs and full grams. Same product line in a larger size almost always drops the cost per milligram.
Why the Same Cart Has Different Prices
Cannabis is taxed and regulated at the state level, so excise rates, testing rules, packaging requirements, and retail markups vary from one market to the next. A cannabis cartridge price comparison chart that mixes menus from two states will mislead you. Keep separate charts for separate markets, or rebuild the chart after a move.
Hardware also moves the price. A cart with a ceramic core and adjustable airflow costs the producer more than a basic wick design, and that difference shows up at the register.
Pitfalls That Skew a Price Comparison
- Comparing 0.5 g to 1 g carts. Normalize to cost per milligram first, or the smaller cart looks cheaper.
- Leaving out tax. Excise and sales tax can change the ranking of two carts that look close on the shelf.
- Assuming price equals quality. High price can reflect brand marketing, limited batch size, or hardware, not better oil.
- Ignoring yield. A cart that clogs at half full delivers fewer usable milligrams than the label suggests.
- Checking price but not test dates. Older batches and fresh batches in the same product line are not equal purchases.
- Forgetting your own use rate. Cost per milligram says nothing about how fast you go through a cart.
Build Your Own Chart in Ten Minutes
- Open your local legal menu and pick five to eight carts in your usual size.
- Write down the total THC milligrams from each product page.
- Add the listed price, then add tax to get an out-the-door figure.
- Divide price by THC milligrams for each row.
- Sort the rows from lowest to highest cost per milligram.
- Note oil type and hardware next to the top three, then decide whether the savings are worth the tradeoff.
Questions to Ask at the Counter
- What is the total THC in milligrams for this cart?
- Is this price before or after tax?
- Do you carry the same oil in a full-gram size?
- When was this batch tested?
- What is your return policy if the cart clogs or leaks?
Buying in store gives you the chance to ask these questions before you pay, and online menus let you run the numbers ahead of time. Do both and your chart gets sharper with every purchase.
