Simple: help them to find better, long term housing. Or, other forms of specialized housing.
Let's take the drug addiction example: homeless persons with drug problems can be best helped by first providing them with no-strings-attached, no-conditions housing to get them off the street and into the access of the care system, then once they're back on their feet again get them to addiction treatment and then into ordinary streetworker care. The point is, people in different conditions need different environments - and different care.
