Idiotic. The only diseases at risk of being transmitted by a 'substandard' crack pipe are the same ones these dipshits are exposed to in a thousand other ways ever day. Share them? OF COURSE they will share them, new or old, at least to the extent a cracksmoker feels like sharing his pipe to begin with. Sounds like the Vancouver government has been experimenting with crack itself.
This is like giving away free single-shot pistols, with ammo, to the first hundred callers on the suicide hotline.
