How to read and understand a cannabis product label

On this page

This page describes the health and safety information found on legal cannabis product labels. It's important to know how to read and understand cannabis product labels to reduce harm when using cannabis.

Terms on a cannabis product label

Cannabis contains hundreds of chemical substances. Over 100 of these are cannabinoids. Cannabinoids are responsible for the effects of cannabis. THC and CBD are the 2 cannabinoids that are the most common in cannabis.

THC

Delta-9-tetrahydrocannabinol (THC) is the main cannabinoid responsible for the intoxication (feeling high) that cannabis users experience as well as other effects typically associated with cannabis use (for example, dry mouth, red eyes, increased heart rate).

CBD

Unlike THC, Cannabidiol (CBD) doesn't produce a high or result in intoxication. However, it can still have other types of effects on the body and brain.

Information on a cannabis product label

Cannabis product packages vary in size and shape, but they all must follow the same labelling requirements. This includes having French and English on all labels. Below are a few examples of product packages.

This section goes over how to find important information to reduce harm when using cannabis.

  • 1. Standardized cannabis symbol

    Example of standard cannabis symbol on packaging for cannabis edible

    This symbol is required on the front of cannabis products that contain more than 10 micrograms per gram of THC.

  • 2. Product brand name and brand element

    Example of logo and brand name on packaging of cannabis edible

    The label needs to have the brand name of the product.

    It can also have a small brand element, such as a logo.

  • 3. Excise stamp

    Example of an excise stamp on an edible cannabis product package and the excise stamps of all provinces and territories

    The excise stamp tells you that the product came from a Health Canada licence holder. However, certain low-THC cannabis products (under 10 micrograms per gram) or prescription cannabis products don't need excise stamps. Each province and territory has a different coloured cannabis excise stamp.

  • 4. THC and CBD amount

    The front of a label must display the total quantity or concentration of THC (Total THC) and CBD (Total CBD) contained in the product.

    It can be presented in different ways. For example:

    • Amount by weight: If a 30-gram package of dried cannabis says "Total THC 180 mg/g", that means that the entire package contains 5,400 mg of THC (180 mg multiplied by 30 g)
    • Amount by unit: If a package of 4 pieces of edible cannabis says "Total THC per unit 2.5 mg", it means that the entire package contains 10 mg of THC (2.5 mg multiplied by 4 pieces)
    • Total amount: If a package of edible cannabis says "Total THC 10 mg", that means that the entire package contains 10 mg of THC
    • By activation: If an oral spray says, "Total THC per activation 8 mg", it means that 8 mg of THC will be dispensed per spray

  • 5. Health warning message

    Example of other required information on edible cannabis packaging

    Using cannabis can put your health at risk. As such, all cannabis products must have a health warning message in a yellow box on the front of a product label. Health warning messages include important information about the effects and risks of cannabis. In early 2025, Health Canada updated its list of messages, which were informed by the latest scientific evidence on the risks of using cannabis, public opinion research with diverse Canadians on message impact, and a peer-review process by international scientific experts.

  • 6. Other required information

    Other required information

    G. Intended use

    Some types of cannabis products have a specific intended use that needs to appear on the label (dried cannabis versus a cannabis topical).

    List of ingredients are required on the product label of:

    • edible cannabis must list food allergens, the presence of gluten and added sulphites
    • cannabis extracts must list food allergens
