Legal vs illegal cannabis: is it worth it?
Legal cannabis used to cost far more, so many people stuck with dealers. The price gap has nearly closed. How legal and illegal compare now.
For the first few years after legalization, legal cannabis carried a real premium, and plenty of people kept buying from a dealer to save money. That maths has changed. The price gap between legal and illegal cannabis has nearly closed, which makes the case for buying legal much stronger than it used to be.
How they compare
| Legal | Illegal | |
|---|---|---|
| Price | ~$5 to 6 a gram | Slightly cheaper (gap ~$1.49/g) |
| Testing | Lab-tested for pesticides, mould, and contaminants | Untested, unknown |
| Labelling | THC/CBD content, batch, often a COA | Guesswork |
| Age control | Sold only to legal-age adults | None |
| Recourse | An accountable, licensed store | None |
Price: the gap has nearly closed
This is the big change. The average price of legal dried flower is around $5 to $6 a gram, and the difference between legal and illegal has shrunk from about $3.59 a gram in 2019 to roughly $1.49. Legal cannabis is no longer the expensive option it once was. For more, see how much cannabis costs.
Safety: the real difference
Price aside, the biggest gap is what you actually know about the product. Legal cannabis is lab-tested for pesticides, mould, and other contaminants, and its potency is verified and printed on the label, often backed by a certificate of analysis. With illegal cannabis, you’re trusting a stranger. The potency is a guess, and there’s no testing standing behind it. That uncertainty is the strongest reason people switch.
Everything else
Legal stores sell only to adults of legal age, and if something’s wrong, there’s an accountable, licensed business behind it. The illegal market offers none of that, and buying from it keeps money flowing to organized crime. Legal purchases fund the regulated, taxed system instead.
The verdict
With the price difference now small and the safety, labelling, and accountability all on the legal side, buying legal is worth it for most people. If price is genuinely tight, choose value brands or buy in larger quantities at a legal store rather than going illegal. And if you’re not sure whether a shop is legitimate, learn to spot the grey market and check where to buy for your province’s official retailers.
