Quebec says 21\. Most provinces say 19\. Alberta says 18\. Same science on everybody's desk — three different answers. So what does the evidence actually support?

Our launch film, [Episode One](https://youtu.be/4CZTgBQrTag?ref=journal.weedwiki.ca), opens that file honestly instead of pretending to close it. The concerns about the developing brain are real and worth taking seriously — and so is the public-health argument that a legal age of 25 would simply hand the 18-to-24 market, the heaviest-using cohort in the country, back to the illicit market with zero quality control and zero ID checks. Every age line is a trade-off between neuroscience and reality; the provinces just drew it in three different places.

The deeper point of Episode One is the deal this desk offers: Canada legalized cannabis and never built the communications layer — so we are building it, in public, with the receipts showing. You rank the stories on [the board](https://weedwiki.ca/news.html?ref=journal.weedwiki.ca), and the best viewer takes get read on the next show. This question is Open File No. 1, and it stays open.

*News, not promotion. Nothing here is for sale, and nobody funds the verdict. 19+ (18+ AB, 21+ QC). Educational journalism under s.16 of the Cannabis Act.*
