Junkies will either shoot up at a safe drug consumption site next to a school, or they will do so alone, leaning against the schoolyard fence, and discarding their HBV infected needles all over the school yard, grassy areas and parking lots.

Denying them help does not make them go away magically. And I speak from experience, when I was a kid in school, junkies would hide behind our school to shoot up at night to not get caught, and it was up to the school administration to pick up the sharps and other paraphernalia.

I'd much rather they be given clean needles, a safe injection site, supervision, a sharps container and help to beat their addiction. Making them suffer just because you don't like them makes them become a problem for everyone.
