Health Canada recently updated its dried cannabis labelling legislation, so you may notice some changes on how THC and CBD information is displayed on cannabis product packaging.
Previously, labelling requirements outlined in the Cannabis Act stated that dried or fresh cannabis not packaged in discrete units must list THC and CBD content in percentages. The new labelling requirements state that dried or fresh cannabis not packaged in discrete units must now list THC and CBD contents in mg/g.
If you wish to convert from mg/g to a percentage, you can use the following formula:
mg/g ➗10 = %
As well, this chart can be used to reference potency between the two measurement scales:
Please keep in mind, the stated mg/g will be the same regardless of retail unit size (1g, 3.5g, 7g, etc.) as it is calculated by gram not total contents.
Any product that has the older labelling, with THC and CBD content listed in percentages, may still be sold. Licensed producers have one year to update their product packaging.
