D has more than one meaning in a cannabis store. On product labels, D most often stands for delta. D8 means delta-8 THC. D9 means delta-9 THC. In price slang, a dime is $10 of cannabis. In concentrate slang, d is the start of the word dab. Context tells you which meaning applies.
D8: delta-8 THC
Delta-8 THC occurs in cannabis plants in small amounts. Most D8 products on shelves contain delta-8 THC made from CBD in a lab. The FDA has not approved any delta-8 THC product for medical use. The agency issued a warning in September 2021 about D8 edibles shaped like candy and about adverse events reported to poison control centers.
D9: delta-9 THC
Delta-9 THC is the main intoxicating compound in cannabis. Federal law limits delta-9 THC in hemp to 0.3% on a dry weight basis. Hemp-derived D9 products sold in grocery stores and smoke shops sit under that limit. Cannabis flower in state-licensed dispensaries measures far above it. Federal law lists delta-9 THC as a Schedule I drug. State law governs sales inside licensed stores.
D as dime
A dime is $10 of cannabis. It is a dollar amount, not a weight. Weight depends on the price per gram at that store. A dime at $10 per gram is 1 gram. At $300 per ounce, $10 buys about 0.9 gram. Legal menus list grams and milligrams, so the word dime shows up in conversation more than on a label.
D as dab
A dab is one dose of cannabis concentrate. The user heats the concentrate on a hot surface and inhales the vapor. Concentrates test from 50% to 90% THC by weight. Flower tests from 15% to 35%. One dab of a high-potency concentrate can carry several times the THC of one joint.
How to confirm which D you mean
- Read the label for total THC in milligrams per serving and per package.
- Look for "hemp derived" or "delta-8" on the packaging. Those products differ from dispensary flower and vapes.
- Check state law. Some states ban delta-8 THC sales.
- Ask the budtender to spell out any abbreviation you do not know.
If a menu, text, or post uses "D" alone with no other detail, ask for the full product name. The letter itself tells you nothing about potency, dose, or legality.
