It's a really good question. People have written about this.
One of the popular models—and the group from Quebec, I think, is very much in favour of this—is something that is found in a number of European countries where they have small co-ops. These are user-run co-ops that pay their staff salaries, but there is no motive to expand membership in any way, no motive to get the current members to use more of the product, and these are key ways of preventing this from becoming a problem.
I think people are familiar with co-ops. There are a lot of people in communities who will join a co-op to get vegetables and so forth. It's really an extension of that very simple concept.
The important thing I think it brings is.... All you want to do is simply serve the existing market and not expand it. What we know from decades of research around alcohol and tobacco is that the more you promote a drug through advertising, the more it's used, and the easier you make access, the more it's used. That's how you expand a market. The problem here is that as the market expands, so does the number of people who have related problems. That's why market expansion is important.
The only other point I'll make very quickly is that, again, we have had a very difficult time internationally, not just here in Canada, of regulating our legal drug industries in a way that they achieve that balance of industry revenue and protection of public health. It's much more difficult than most people think.
