Yup. Just like any new market/product. A pile of people rush in, a pile fail, and the rest consolidate into a few well established players and dominate the market.

In a previous career, I was involved in salmon aquaculture in the Bay of Fundy. When I first got in, along with dozens of other companies, we were getting $8.50/lb at the farm. Five years later, we were struggling to get $2.50/lb, which wasn't enough to cover production costs. Thirty years later, there's basically one company dominating in the area. Profitability is still dodgy.

StatsCan has been doing a fair amount of surveying on cannabis in general. They found that 69% (nice) of users buy from legal storefronts or legal websites. Another 25% was home-grown, or from friends/family. The remaining 6% was from dealers or illegal shops/websites.
