The California State Senate on Tuesday passed Assembly Bill 186, which allows San Francisco, pursuant to a 3-year pilot program, to implement safe injection sites. 

The bill is authored by Assemblymember Susan Talamantes Eggman (D-Stockton) and co-authored by Senator Scott Wiener (D-San Francisco). 

AB 186 permits San Francisco to establish facilities where people can use controlled substances under the supervision of staff trained to treat and prevent drug overdose. 

Those trained staff members can also link people to drug treatment, housing, healthcare, and other services. 

Last year, the bill was passed by the Assembly, making it the first legislative body in the U.S. to pass such a bill, but was two votes shy in the Senate.

AB 186 now heads back to the Assembly for a concurrence vote. 

If the Assembly votes to concur, the bill will be sent to the Governor’s desk for his signature.
