We need to acknowledge that San Francisco has spent billions over decades on homelessness programs, yet the crisis persists, leaving us to ask: Is this truly the best we can do? Are we investing efficiently, or are we simply maintaining a broken system?
For meth, crack, etc there are effectively no pharmacological interventions available. And many (most?) of the street homeless have dual addictions to a stimulant and an opioid, so even if they did manage to switch from fentanyl to buprenorphine they would almost certainly be extremely unstable with their stimulant addiction.
Obviously there are psychological interventions and peer support groups, but these require quite a lot of stability to stick to and get to, which I think is extremely difficult for someone in a very chaotic addiction cycle.
To me, it seems some of the billions that cities spent on social services for homeless should be diverted (or in addition to) to pharmacological research. There is so little funding available for this - I read Prof David Nutt was doing an interesting PET study for kappa opioid response in addiction but ran out of funding. The funding requirements were low-medium hundreds of thousands of dollars and couldn't find it to continue the research.
The current status quo seems a bit like trying to treat TB without antibiotics. The treatment back then was basically similar to current 'rehab' programs - send them to a quiet place and give them care and help. Obviously not a bad thing to do; but once you had antibiotics the prognosis improved by many orders of magnitude almost overnight (and a lot less costly to provide).
Isn't that still treating a symptom, rather than the core problem? If homelessness is caused by drug addiction, what causes drug addiction? Underlying mental health? Lack of opportunity? Government welfare dependence?
