LAUSR

Objective Law is an important factor in the diffusion of syringe services programs (SSPs). This study measures the current status of, and 5-year change in, state laws governing SSP operations and possession of syringes by participants. Methods Legal researchers developed a cross-sectional data set measuring key features of state laws and regulations governing the possession and distribution of syringes across the 50 US states and the District of Columbia in effect on August 1, 2019. We compared these data with previously collected data on laws as of August 1, 2014. Results Thirty-nine states (including the District of Columbia) had laws in effect on August 1, 2019, that removed legal impediments to, explicitly authorized, and/or regulated SSPs. Thirty-three states had 1 or more laws consistent with legal possession of syringes by SSP participants under at least some circumstances. Changes from 2014 to 2019 included an increase of 14 states explicitly authorizing SSPs by law and an increase of 12 states with at least 1 provision reducing legal barriers to SSPs. Since 2014, the number of states explicitly authorizing SSPs nearly doubled, and the new states included many rural, southern, or midwestern states that had been identified as having poor access to SSPs, as well as states at high risk for HIV and hepatitis C virus outbreaks. Substantial legal barriers to SSP operation and participant syringe possession remained in >20% of US states. Conclusion Legal barriers to effective operation of SSPs have declined but continue to hinder the prevention and reduction of drug-related harm.
