Oh yeah, for sure, no doubt - if there was any funding available for such programmes. All the research on this points pretty conclusively towards prioritising getting unhoused people into stable accomodation first and foremost, it’s impossible to recover from PTSD living on the streets for example, and we would also need a robust public health focused approach to drugs, e.g. decriminalizing drugs and treating them as a health issue rather than a criminal one. That, plus funding the NHS appropriately, esp. mental health, would work miracles and change so many people’s lives.

But instead the bastards running the show would rather loot the public purse for all it’s worth to line their pockets before getting a cushy 6 figure job as a lobbyist.
