Good cannabis cartridge deals show up on dispensary menus every week, but not every discount is worth your money. A deal usually means the retailer wants to move that cart out the door, not necessarily that the oil is bad. In legal states, wholesale distillate prices have fallen, so a reasonable price per half gram may be lower now than it was a few years ago. Still, I want to know why the cart is cheaper.

Advice: Compare Price to Potency and Dosage

Before you look at percentage labels, figure out how much THC you actually use in a day. If you take about five hits per day and each hit from a standard cart is roughly 3 milligrams, one gram cartridge equals many days of use, but not forever. Divide the total THC in the cart by the price. The resulting cost-per-milligram is more honest than the cart's color or discount sticker.

Parameters: What I Check Before Adding a Cart to a Bag

  1. Packaging date. Cannabis carts are shelf-stable for a while, but oil that sat in a supply chain for over a year usually tastes dull.
  2. Test label and batch number. Licensed stores should show you a certificate or a QR code that walks you to test results.
  3. Hardware brand. Ceramic coils warm up comfortably. Clogged air paths can make a deal useless.
  4. Drop in price. If an item is priced 40 percent below every comparable cart in the display, make the employee explain the reason.

Pitfalls That Turn a Discount Into a Waste of Cash

The “too old, too clean” problem

Clear oil is not necessarily fresher oil. Distillate can be winterized and refined many times. I would rather buy a slightly darker live resin cart that shows a harvest date than a glassy cart with a loose supply chain label.

Buying for the sticker rather than the experience

A 2-for-$25 deal on extra-potent cartridges looks tempting, but if you only use one cart a month, the second one may sit for weeks and lose flavor.

Unregulated sources

The CDC pointed to vitamin E acetate as a likely culprit in EVALI cases tied to black market THC vapes. If a deal comes from a delivery service without a state license, it is not a deal. It is a gamble.
