I'm not sure if you've had a drug addict in your life at any point, and if not that is a blessing.
Drug addiction is a dark place and it's very common that the availability of free support programs is entirely rejected by the user, and the only hope at a normal life requires forceful intervention by family and friends.
The only way to solve drugs on the street is to look at the cities that have solved them and copy what works. And, at least with what I'm familiar with, arresting people tends to work and alternatives tend to not.
Oh yeah, 60 years of arresting people in the US for drug crimes has gone so well. Couldn't be better! Cities that decriminalized have better outcomes.
I hope people like you lose every election for the rest of time.

What I've read many times is that (essentially) the oppposite is widely accepted consensus: Arresting never works. The US tried the 'drug war' for decades and it was ineffective. Do you have evidence otherwise? It's also unjust to criminalize illness and medical problems for poor people (rich people get sympathy, rehab, and lots of second chances).
What does work is overdose prevention, including needle exhanges and safe injection sites, treating addition as the disease it is (which is how it's treated for rich people), and housing (people experiencing the great instability and stress of homelessness are much less likely to make other changes). Maybe some others I'm not thinking of, too.
You seem to be equating "homeless" with "drug addict". The article talks about taking away public benches because of homelessness.
There are different programs needed for drug addiction than for homelessness. Not everyone who's homeless has a drug problem, and not everyone with a drug problem is homeless.
