In the context of cities with permissive attitudes toward drugs, like San Francisco, many homeless people stay in encampments to use illegal substances more freely and easily than they can in the shelters. Many policy makers understand this. “I went out with a team twice to have conversations with people to get an understanding of what they’re dealing with,” said Mayor Breed in 2020. “It was absolutely insane. Most of the people did not take us up on the offer [of shelter and services].”
