Other than the idea that creating fully effective airborne drugs isn't all that simple, especially for something so experimental -- I would like to think that the authority in the story, clearly tries to better provide for the demons, who are essentially 2nd-class-citizens, instead of making it their top priority to antagonize them and shut them down as forcefully as possible. Utilizing your citizens instead of killing them, makes much more sense to me, especially if the story already shows that's what's being done.
If the mother would've denied intervention from the government, however, it would've been fair game, yeah.
