I'm nodding because I'm in complete agreement.
Like fentanyl, these drugs are not very difficult to synthesize. Even if you could somehow snap your fingers and make our borders impermeable, somebody would make it here. You would see more labs in Calgary than you currently have, because the market is there. It goes back to the whole issue of drug use just being an element of human behaviour.
I think the way to tackle this is not through trying to tackle the supply side. It's trying to tackle the demand side. If you can help the people who are currently using it, most of whom are wanting help, you're going to tackle the supply indirectly.
