They want people to be addicted and controllable. Making it a "disease" takes away personal accountability and agency. You aren't weak, you are sick. Yeah, that will get people to change.

We need to go back to making drugs and other degenerate behavior taboo and socially stigmatizing so people are less likely to go down those paths. Stop coddling people and make them grow a thick skin again.
