That's another really good question.
I have to mention that the Portugal model has been evaluated. As with any political or scientific evaluation, there are limitations, so it's difficult to isolate causes and effects. However, we have, scientifically, a consensus that the model here has more benefits than the reverse.
We have to say the model is still a punishing model. Now it's better, but it's not reaching all drug users and heavy drug users. It mainly reaches cannabis users in big cities. It's not perfect. It's really complex to have policies that work.
We need to try something. Portugal did, and it's no catastrophe. It seems to be a step in the right direction.
