Would it?1. I'm all for making clean needles harder to access if anything it would at least reduce drug use which was the idea of the proposal in the first place....
A lack of free, clean needles is unlikely to stop drug use in first time users. If you can manage to obtain the drugs, obtaining a clean needle shouldn't be overly difficult. Not to mention that if you're taking drugs, it's doubtful you're one to care for consequences much, otherwise you wouldn't need the needle in the first place. Truly, I'll be damned if someone can show me a case saying "I was going to take drugs, but I had no needle, and could never find one, so I never took drugs in my life."
An addicted brain craves the drug, rational thought about a lack of clean needles can easily get pushed aside. I wouldn't count on the lack of clean needles stopping people, otherwise we would have zero drug use in areas without a needle exchange program. Perhaps stories of "my mate died from an infection" help somewhat towards the cause, yes, but that's slightly unethical, letting people put themselves in harms way so they get made an example of in the community.
