The filter of choice: filtration method preference among injecting drug users

Injection drug use syringe filters (IDUSF) are designed to prevent several complications related to the injection of drugs. Due to their small pore size, their use can reduce the solution’s insoluble particle content and thus diminish the prevalence of phlebitis, talcosis…. Their low drug retention discourages from filter reuse and sharing and can thus prevent viral and microbial infections. In France, drug users have access to sterile cotton filters for 15 years and to an IDUSF (the Sterifilt®) for 5 years. This study was set up to explore the factors influencing filter preference amongst injecting drug users.
