Use of fentanyl test strips by people who inject drugs: Baseline findings from the South Atlantic Fentanyl Test Strip Study (SAFTSS)

Research published during the early fentanyl period exposed a growing concern of unwitting fentanyl exposure and a general willingness to use fentanyl test strips (FTS). A paucity of FTS studies over the last several years has restricted our ability to understand FTS use in the late fentanyl era. The South Atlantic FTS Study (SAFTSS) was established to investigate contemporaneous changes in FTS use and drug use behavior among a rural cohort of PWID.
