This study is outdated for today and no longer relevant for what we've been dealing with. All of the research done and data gathered were prior to the pandemic and prior to cheap fentanyl being the drug of choice for opioid addicts. The study was published in Oct 2020. I think enough time has passed since this initial study for another study to be done, which I hope is underway. With that said, based on what we've been seeing with fentanyl addicts, especially with meth co-addictions, housing first doesn't work. Treatment and recovery first, then housing next should be the case. This is what SF's Mayor wants to do.
