A cannabis potency chart by type sorts products into four groups based on how much THC they deliver. Flower and pre-rolls test in the 15% to 30% THC range, vape cartridges and concentrates sit between 60% and 90%, edibles are dosed in milligrams per serving instead of percent, and CBD products are labeled by CBD content. The format changes the math, so a 25% number on flower and a 25 mg number on a gummy are nowhere near the same thing.
Cannabis Potency for Edibles Dosing: A Practical Guide
Potency labels come from third-party lab tests on each batch. Results shift from harvest to harvest, even under the same strain name and brand.
THC potency ranges by product type
These ranges reflect common lab results on legal US cannabis products. Individual batches vary by cultivar, grow method, and extraction style.

- Flower: 15% to 30% THC, with top-shelf cultivars reaching 33%.
- Pre-rolls: 18% to 28%, plus whatever concentrate or kief gets added.
- Hash: 20% to 60% THC.
- Kief: 40% to 60% THC.
- Wax, shatter, live resin, rosin: 60% to 85% THC.
- Distillate: 80% to 95% THC.
- Vape cartridges: 70% to 90% THC.
- Edibles: 1 mg to 10 mg THC per serving, with many states capping a package at 100 mg.
- Tinctures: 1 mg to 5 mg THC per dropper, sometimes higher.
- Topicals: THC listed by weight, with little to no psychoactive effect.
Flower and pre-rolls
Dried flower carries the most THC the plant makes on its own. Breeding pushed average THC from single digits in the 1990s to the high teens and twenties today. A 3.5 gram eighth of 25% flower holds about 875 mg of THC before combustion destroys much of it.

Concentrates, hash and kief
Concentrates strip plant material and leave cannabinoids behind, which is why the numbers jump. Kief is the simplest version: trichomes sifted off flower. Solvent extracts and rosin go further and land in the 60% to 90% range.
Vape cartridges and distillate
Distillate is refined THC oil that can climb into the low 90s. Cartridges blend that oil with terpenes, so the label shows the final mix, not the raw distillate. A 1 gram cart at 85% holds about 850 mg of THC.
Edibles, drinks and tinctures
Edibles skip percentages and use milligrams. A standard serving in legal US markets is 5 mg to 10 mg THC. The liver converts THC into a stronger metabolite, 11-hydroxy-THC, which hits harder and lasts longer than inhaled THC.
Why edible potency does not compare to flower potency
Inhaling sends THC to the bloodstream in minutes, and a large share burns off before it reaches you. Eating sends the full dose through the liver. That is why 10 mg of edible THC can feel stronger than several puffs of 25% flower.
Edible effects start in 30 to 90 minutes and can run 4 to 6 hours. Inhaled effects start within minutes and fade in 1 to 3 hours.
CBD potency ranges by type
- Hemp flower: 10% to 20% CBD with under 0.3% THC.
- CBD oil and tinctures: 5 mg to 50 mg CBD per mL.
- CBD gummies: 10 mg to 50 mg per piece.
- CBD vape oil: 30% to 60% CBD.
- CBD topicals: 50 mg to 500 mg per container.
Marijuana-derived CBD products can carry more THC than hemp-derived ones. Read the THC line if you want to avoid a high.
How to read a potency label
- Find total THC. Some labs print THCA and THC apart. Total THC = THCA x 0.877 + THC.
- Check the serving size and the number of servings. A 100 mg chocolate bar cut into 10 pieces is 10 mg per piece.
- Look at CBD and minor cannabinoids such as CBG and CBN.
- Note the batch date and the lab name. Potency drops as flower ages and dries out.
Does higher THC mean a better high?
Not always. Terpenes, other cannabinoids, your tolerance, and your body chemistry all shape the experience. Many consumers say a 20% flower with a terpene profile they enjoy works better than a harsh 30% batch.
High THC also raises the odds of anxiety, racing heart, and short-term memory trouble. Low and slow dosing is the safer path.
Picking a potency that matches your tolerance
- New consumers: flower under 15% THC, or 2.5 mg of edible THC.
- Occasional use: 15% to 22% flower, 5 mg edibles, one or two puffs of a cart.
- Daily consumers: 22% to 30% flower, 10 mg edibles, dabs and distillate carts.
Tolerance builds with regular use. Take a break or drop to a lower dose when the same product stops working.
Cannabis potency chart FAQ
What is a normal THC percentage?
Most legal flower today tests between 18% and 25% THC. Concentrates run far higher, and edibles are measured in milligrams instead.
How much THC is a lot?
For a new consumer, anything above 5 mg of edible THC or 20% flower counts as a strong dose. Experienced users handle 10 mg edibles and 25% flower without trouble.
Can cannabis reach 100% THC?
No. Distillate tops out near 95% because some plant compounds and lipids remain. Flower cannot pass the mid-30s.
Do potency charts apply to hemp products?
Hemp follows the same logic with CBD as the main number. Federal law caps hemp at 0.3% THC on a dry weight basis.
