Daily drug use may actually be the correct way for some people to maximize the integral of happiness over their lifetime. Especially for those at the bottom with limited prospects. I don't think most of HN can fathom what it's like to actually be completely useless. You're delusional if you think the homeless problem is a bunch of software engineers who tried heroin once, and left FAANG to get high every day.

> Should we require drug tests for homeless people to receive government help like SF CAAP payments?

This is a great idea. If you want society to invest in you, you have to take basic steps to be a worthy investment. But even this is predicated on the idea that what these drugs users are doing is wrong, and that they should instead do something that lets the rest of us reap the benefits of their productivity. Who are we to demand someone be more productive for our own benefit? We're right to want something in exchange for our investment, but there's no place to stand and say a drug user is wrong for not taking the deal.
