"Injection site" normally refers to the place on the body where you inject a drug or medicinal drug.  Strange to read it used this way again and again by these agencies and organizations.  Couldn't they be injection centers?  Injection shelters?

Mixed feelings on the topic itself, obviously the point is mainly to help those not using, the folks in the neighborhoods where people don't feel safe or feel it is safe for their kids to be because there are drug users there.  It seems reasonable, since a second effect could be helping the users themselves, but there should be some kind of evaluation system automatically in place to make sure this goes the way the agencies predict it will.  I can potentially see users at the centers in *addition* to users in the neighborhoods.
