I live near Zurich, which in the Nineties had a lot of issues with public drug use. For example, all bathrooms in public places and major department stores had blue lights instead of normal lights because you can't see the veins in your arm so it's hard to shoot up. There was also a serious crime element as addicts were robbing people to get money to buy drugs. Now, you can get them for free at clinics. With their new policies, the addicts are no longer nearly as visible and the related crime seems to be practically gone. The blue lights in the bathrooms are gone, needle park is gone and it's generally a very nice city to live in.
