Improved syringe disposal practices associated with unsanctioned safe consumption site use: A cohort study of people who inject drugs in the United States

When people used this unsanctioned safe consumption site, they disposed of significantly fewer syringes in public places, including streets, sidewalks, parks, or parking lots, than people not using the site. This study helps allay concerns that implementing safe consumption sites in the US would lead to increases in improperly disposed syringes.
