Syringe disposal among people who inject drugs before and after the implementation of a syringe services program.

Introduction: Due to the increase in people who use opioids in the US, there has been a steady increase in injection drug use. Without access to safe syringe disposal locations, people who inject drugs (PWID) have few options other than improper disposal, including in public places. In 2016, Florida's first legal Syringe Services Program (SSP) was established in Miami.
