Reporter Stephen Quinn talks about a program in Vancouver, Canada that provides clean needles and a safe injection site for heroin addicts. The idea is to prevent HIV, hepatitis and other blood-borne disease transmission. The program is controversial, and critics say it encourages drug use. He'll also talk about the politics surrounding the program. Quinn works for the CBC, the Canadian Broadcasting Corporation.
