Canada is a strangely different animal than the United States. We have a big booming military-industrial, prison-industrial complex that we predicate the majority of our actions on feeding. Weed legalization, contrary to popular belief, is being pretty heavily contested in even "weed friendly" (but not legalized) states. Take New Hampshire. We have Vermont which has decriminalized, Maine which allows medical. We "on the books" allow medical marijuana but in practice there are no dispensaries and the biggest lobby group opposing it is the police associations. Not to mention a crushing heroin epidemic (that has nothing to do with weed), the public is surprisingly anti-weed/anti-drug legislation.
Part 2. Canada. Canadians have a sort of blind altruistic approach when considering their government. The concept that a state-run actor should be the distributor/main agent of "vices": weed, alcohol, tobacco, firearms is perfectly acceptable to the majority of Canadians. Here, in the United States, we see it for what it is: a big cartel. If weed were ever legalized, as we've seen in the states that have legalized it, it is a tightly run sector of the government's income. In New Hampshire, for instance, the state runs all liquor and gambling. Private sector has little to no say in how those affairs are run. Weed would, invariably, be just another stage venue for our state government to take control of. If the Federal government ever got in on the racket, they'd demand a BIG slice of the pie from states.
Part 3. Weed is great. There's almost no downside. But to have one's name placed upon a database or registry (which the US government has a very bad track record of keeping discrete), not have weed prices vary depending upon market conditions, and have those systems ironed out into a factory line weed-money assembly is both a cruel, ironic joke for the very idea of personal liberty and freedom. Which I know -- Canadians don't really care about either -- but in the United States we still have some semblance of it.
TL;DR -- I don't think the weed market is going to save anything.
