Could vending machines be a viable way of providing injection drug users with sterile syringes that may prevent transmission of HIV and other bloodborne pathogens?
Yes, said French researchers who analyzed survey results from injection drug users who obtained sterile syringes from pharmacies, needle exchange programs, and vending machines in Marseilles. The syringe vending machines, introduced in Marseilles in 1996, are similar to coin-operated soda machines except they exchange used syringes for clean ones.
