Yes. It does make it okay. Welfare should be given on no conditions. If they want to spend it on drugs and won’t be able to afford food because of it, that is their choice. Why should people who get assistance be told how to spend that money? Should they also be restricted from buying beer with that money? How about sugary sodas? How far are you willing to go to tell people how they should be allowed to spend the money given to them when that is not a requirement for anyone else’s money?
The system should also offer them assistance to break addictions regardless.
