Democratic California Gov. Jerry Brown vetoed a bill that would have allowed San Francisco to open what could have been the nation’s first supervised drug injection sites. “Fundamentally, I do not believe that enabling illegal drug use in government sponsored injection centers – with no corresponding requirement that the user undergo treatment – will reduce drug addiction,” Brown wrote in his veto message. The veto drew sharp criticism from proponents, who argue that providing clean, monitored space for drug users to use illicit drugs would reduce overdose deaths. “I am shocked that the Governor turned his back on the science and the experts and instead used outdated drug war ideology to justify his veto,” said Laura Thomas of the Drug Policy Alliance.
