There's no math I can imagine in which restricting access to clean needles could help stem an epidemic being spread by dirty needles.
Kelley, We are obviously comparing apples to oranges. Perhaps free needles MAY help prevent some junkies from getting HIV or one of the several types of hepatitis. I am more concerned with children, police and other innoccent victims of needle sticks. More needles = more contaminated needles lying around. Are you using Common Core math?
