What Do THC Percentages Mean?

THC is the primary compound in cannabis that produces intoxicating effects. The percentage tells you how much THC is present in the total weight or volume of your product. For example, the label on cannabis flower might read “18% THC,” which means 18% of the flower’s weight comes from THC. Some edibles or beverages also include a percentage, but you usually see the amount in milligrams per serving.

What these figures boil down to is potency. A higher THC percentage suggests a higher potential for strong effects, but these numbers aren’t the whole picture. How you feel will depend on how you consume your cannabis and your individual response.

How to Read THC Percentages Across Products

The numbers mean different things depending on what you’re buying:

  • Flower: Most cannabis flower falls somewhere between 15% and 25% THC, though some strains are lower or higher. Anything over 20% is potent for many people, but other compounds (such as terpenes and minor cannabinoids) can also play a role.
  • Edibles: Edibles are usually labeled by milligrams of THC, but sometimes you’ll see a percentage. Keep in mind that 5mg of THC in an edible can give a much stronger, longer-lasting effect than a puff on a joint because of how the body processes THC when eaten. Take your time and keep your intake low if you’re new to edibles.
  • Drinks: Like edibles, cannabis beverages often give their THC content in milligrams. They come in a range of THC strengths, from a 2-5mg low dose to 10-20mg in a high-dose drink. You may notice the effects more quickly with drinks than traditional edibles, and they also last longer than inhaled cannabis.
  • Concentrates: These are the most potent, with labels often showing 60-90% THC. Such high numbers are not for everyone, as the experience can be intense even in very small doses.

Do THC Percentages Matter When Choosing Cannabis?

It’s easy to assume a higher percentage equals a better or stronger experience, but that’s not always true. Here’s why:

  • Personal tolerance: If you’re new to cannabis, you’ll have a different response to 15% THC than someone who consumes it regularly.
  • Product type: Your consumption method matters, as a 10mg edible feels different from flower or a vaporizer.
  • Other compounds: The ingredients of a cannabis product can influence the THC’s potency, as terpenes, CBD, and other cannabinoids play important roles in the overall effect.
  • Desired outcome: Sometimes, a product with a lower THC percentage is the better fit for a relaxed or social experience.

Rather than focusing only on THC percentages, try to make your cannabis purchases with your comfort level in mind. Asking questions at the dispensary is always encouraged.
