Will the homeless with drug addiction go cold turkey during covid19?

First, I don't think most homeless are heavy users. It takes money to be a heavy drug user. I've known heavy drug users who went through like $10k in drugs in one year. That's more than some homeless people live on all year.

So I suspect the "hard core junkies trope" is somewhat overblown.

Second, they are having much more serious problems, like difficulty getting food:

It's quite ugly at the moment and I don't know what we can do about it.

There are pictures of homeless people still on the streets of San Francisco ..and they are ‘exempt’ from social distancing as per London Breed, the mayor of SF.

I don’t understand what that means? They are ‘on their own’ ..to do what? Die?

I was discussing this with my wife today. But we are assuming that the supply will stop, right? Will it really stop though?
