re: To what extent is society morally obligated to save heroin addicts?

It’s a medical professional’s job to save lives, so at the point that they become involved, there are no options unless the ODing idiot is wearing a DNR tag.

If you want personal accountability to take the upper hand, start voting to legalize all drugs instead of having the government shield people from themselves.

Edit: Regarding the feelings of the loved ones of the ODing idiot, those feelings are apparently not reciprocated by the person who put too much escape drug in their body.
