While this may seem counterintuitive for an organization devoted to weaning addicts off crack, the shelter hopes that by selling cheap, clean pipes it can reduce the spread of diseases like Hepatitis C and HIV. Homemade pipes are typically made inexpertly out of glass tubes and susceptible to breaks and splinters, both of which can cause wounds. The vending-machine pipes are brand new, made of tougher Pyrex glass, and cost only 25 Canadian cents (US$0.23), compared to the up to C$10 they normally costs addicts.

The “harm reduction” rationale behind giving crack users free or cheap pipes is similar to that behind giving heroin users free needles—something that Canada does quite a lot of. Vancouver is a more progressive city than most: It not only provides free needles for heroin addicts, but operates professionally supervised injection sites—the only ones in the country.
