78% of purchases from legal sources

What the researchers found

Among 2,686 Canadian cannabis consumers, 78% of purchases came from legal sources. Legal dried flower cost 23.8% more than illegal, vapes 18.7% more, and hash 38.4% more. Legal capsules were 28.4% cheaper. No significant price differences for edibles, drinks, concentrates, drops, or tinctures.

Why it matters

Price competition between legal and illegal markets is central to legalization's success. This data shows meaningful progress in Canada, with most purchases now from legal sources and price gaps narrowing.

The numbers in context

2,686 respondents. 78% from legal sources. Legal premiums: dried flower +23.8%, vapes +18.7%, hash +38.4%. Legal discount: capsules -28.4%.

How the study worked

National surveys in 2022-2023 among Canadians aged 16-65 as part of the International Cannabis Policy Study. 2,686 respondents reported price, quantity, and source for nine product types.

What this study cannot tell us

Self-reported prices and sources. Cross-sectional. No quality comparison between markets. Quantity discounts complicate comparisons.

How to read the evidence

Moderate: large national survey with product-level data, but self-reported prices.

When this study was published

Published in 2025, with data from 2022-2023.

The bigger picture

Canada's experience offers lessons for other countries. The 78% legal market share suggests the regulated market has largely succeeded, though persistent premiums for dried flower indicate room for further competition.

Questions still open

  • Will legal market share continue to grow?
  • What role does product quality play beyond price?
  • Are quantity discounts in illegal markets a barrier to full legal transition?

Common questions

Is legal cannabis more expensive than illegal?
In Canada, legal dried flower costs about 24% more and vapes about 19% more. However, legal capsules are cheaper, and several product types show no significant price difference.
Has Canadian legalization reduced the illegal market?
About 78% of purchases came from legal sources five years after legalization, suggesting substantial displacement of the illegal market.
