In this undated photo provided by Tyrone Clifford, Clifford poses for a picture in San Francisco. California Gov. Gavin Newsom’s administration is supporting a plan that would pay people struggling with drug addiction to stay sober. Called contingency management, Newsom’s administration is asking the federal government permission to pay for the treatment through Medicaid. Clifford, who was addicted to meth, enrolled in a program run by the San Francisco Aids Foundation that has been running a small privately-funded contingency management program for years. Clifford completed the program without a positive test and used the money he received to buy a laptop computer so he could go back to school. (Tyrone Clifford via AP)
