Safer drug consumption services (SCS) are designated sites where people can use drugs under the the safety and supervision of trained personnel. Over 100 sites exist in 67 cities in eleven countries around the world. After 30 years of operations, SCS have demonstrated to prevent overdose, HIV and hepatitis C transmission, injection-related infection, and public disposal of syringes. SCS promote engagement and referrals to other support services, including housing placement and drug treatment. Contrary to popular belief, they do not increase drug use, crime, or bring drug use into communities. And they save millions of dollars a year.
