Project-Based Housing First for Chronically Homeless Individuals With Alcohol Problems: Within-Subjects Analyses of 2-Year Alcohol Trajectories by Susan E. Collins et al describing how providing housing to people with alcohol addiction problems, without requiring them to be abstinent of alcohol (as many welfare programs require) resulted in decreased alcohol use. This was an example of ensuring the addiction did not stigmatise the user and further lower their living standards and reinforce their alcohol use.
In the same issue, Michael Ong et al publish Estimates of Smoking-Related Property Costs in California Multiunit Housing in which they attempt (with a 22% response rate) to estimate the impact of smoking renters on property costs. They calculate that "implementing statewide complete smoke-free policies may save multiunit housing property owners $18 094 254 annually."
