The longer you are unhoused, the more that you are in a chronic state of danger. Opioids turn that stress response off for a moment and simultaneously make it harder to get out of the situation that caused the problem.
The Opioid addicts don't care about being seen in a way that the invisible homeless do.
The people whose mental health crises are exacerbated by being homeless are more likely to be visible because they have no reserves left. And Fentanyl is a good way to ignore that mental health crisis for a moment.
The drug addiction happens because of the trauma in a vast majority of cases. Poor decisions may compound, but trauma causes rational decisions that also have the negative consequences that compound.
And again, treatment doesn’t even work most of the time, especially if the patient is unwilling. We are just throwing away our money here when we could focus it on the non-addicted homeless instead, get them housed, and prevent them from getting addicted to drugs. Sober housing helps these people a lot, and could prevent the problem from getting worse, because once they start doing drugs, it’s pretty much over.

It certainly happens that people get addicted to opioids and then their lives fall apart as a result of addiction but it's important to consider how despair itself can lead to addiction.
"If your life had descended to a point where you had to go to the bathroom in an alley and use scrap paper to wipe, or were eating your lunch that you fetched from a trash can on the street in the rain, there's a good chance you would use opioids to numb the pain of that existence, too."
And once you start using some of the most powerfully addictive substances we know, it's not about "flaws of character" or anything else, now you've messed with brain chemistry, in some cases, permanently.
It is really sad that we have equated drug addiction with homelessness. We should really treat them as separate problems, since one is much easier to solve with social resources than the other.
