Supervised injection sites

I have always supported supervised injection sites.We don't want to encourage people to start using drugs but if they already are addicted we need to reduce the chance for harm to occur.I think it would be great if they had treatment and social services in the same place as the article says they do in Europe.If we can get some of these people in the door ,we might be able to do something to help them instead of just throwing them in jail and ignoring the underlying problems.i hope the conservative government will come to See this.
