i do not have any idea how to solve housed people turning to drugs/alcohol to try and solve internal emotional pain...maybe more & more education.
A nice pair of contrasting data points here is WA and West Virginia. Drug usage and addiction, as well as mental health problems, in West Virginia far outstrips Washington - see https://www.kff.org/statedata/mental-health-and-substance-us... However homelessness in Washington is far, far worse than in West Virginia. West Virginia had almost the lowest rate of homelessness in the country.
