San Francisco Democratic Mayor London Breed recently proposed mandatory drug testing and treatment for those receiving welfare.

On Tuesday, Breed offered a plan to tackle the city’s homeless and substance abuse crisis. Breed’s initiative would require those suspected of substance abuse problems who want to receive funds through the County Adult Assistance Program to undergo mandatory drug testing and treatment programs. Those who refuse testing and treatment interventions would be ineligible to receive county-funded cash assistance.

The program currently provides housed residents up to $697 per month, and homeless residents are guaranteed $105 per month and a shelter bed, the New York Post reported.
