If you are going to share a needle with someone bleach will not kill hep c.
HYDROGEN PEROXIDE DOES. Please share this information with all your friends. It probably saved my life.
Do not risk this at all. Do not share needles, cookers or even the same water as someone else that's if they have put a used needle in it. You can get needles in most states at needle exchanges atleast i believe and pharmacies. Someone from the US could chime in on this. I am from Canada and i have never had a problem buying syringes at a pharmacy. I have never even been asked what i wanted them for.
So just don't share any gear at all.
