You do not have to go to either criminalizing and throwing people in prison. I don't think you should do that for people who are using any drugs. I think they absolutely need treatment.

There's a very complex connection between crime and addiction, because a lot of people are committing crime to either fuel their drug habit, which they're going to do anyway, whether it's legal or not, or under the influence of drugs, which they're going to do more, if it's legal.
