So I'm curious what effect this will have on prices. Because if pricing is anything like alcohol in Ontario then there will still be a lively black market and, if legalized, a personal-growing boom.
In Ontario alcohol can only be bought at two government run retail stores called LCBO and "The Beer Store" at much higher prices than the US and even Montreal. Unlike in some other provinces you can't walk into a grocery or corner store, you have to go to the predefined locations of the alcohol stores, which typically close at 9pm, making it harder to get alcohol. Especially if you don't drive.
I hope they don't make the same mistake with weed, because the market dynamics are different.
Quality would definitely be the main difference. Although I have friends that have made decent wine and beer themselves.
That plus the extend time weed has been on the black market made the information on how to grow it widely available to average consumers. No trade secrets there really.
wat? my friend, i fear you have overlooked modern homebrewing; world-class beer is being made in peoples' kitchens / basements / garages all over the place. :)
