THC Potency

Potency refers to the amount of THC in a cannabis product. THC content is expressed in milligrams per gram (mg/g) or as a percentage of milligrams per gram of cannabis. For example, if a product is labelled 15% THC and 150 mg/g, it has 150 milligrams of THC per gram of cannabis. It is impossible to have dried flower cannabis with 100% THC, but cannabis extracts (which have been distilled) can have up to 90% THC. As a natural product, the THC content in a dried flower cannabis product may vary from product to product and between lots of the same strain.

All information on THC content for our listed products is provided by the federally licensed producers from which we purchase the product.

By law, THC content is indicated on the packaging of every cannabis product sold on Additionally, products with THC amounts over 17% and 20% are labelled as “strong” and “very strong,” respectively, to guide customers in product selection.

Choosing Products Based on THC Potency

The effects of THC will be different for everyone. When choosing a product, consider not only the THC potency potential, but also the method and amount of consumption along with personal factors such as your age, your sex, your health history and previous experience with cannabis. Consult with your physician if you have questions.

  • Consuming small amounts of THC can produce effects such as relaxation, heightened happiness, arousal and creativity, more sociability and energy, and an increased appetite
  • However, consuming large amounts of THC may produce overwhelming, unpleasant or harmful effects
  • Consider products with low THC potency and/or at least a 1:1 ratio of THC to CBD (cannabidiol) to help reduce the likelihood of unintended effects. Remember to consume it slowly and in small amounts.
  • Remember that even the same products can vary between lots of the same strain. Please check labels carefully to be sure of the actual THC content in the product you selected.
