Understanding THC

Read the label as a whole

THC is short for delta-9-tetrahydrocannabinol, a cannabinoid found in cannabis. It is the cannabinoid most associated with intoxication, which is why its amount and the way it is presented on a package matter.

Canadian labels commonly show THC content before and after activation. Total THC is an estimate of the THC available if the product is used as intended; the relationship is different across formats.

Potency varies by product category and package. A higher number does not automatically mean a better fit for an adult or a more useful product. For edibles, onset can be delayed. Keep products away from children and do not drive after using cannabis.

• THC is one cannabinoid, not a complete description of a product.
• Label language and units differ by format.
• Potency is not a quality ranking.
• Health questions belong with a qualified health professional.
