I was thinking of things like sexcrime or thoughtcrime, though I don't think it is called a war in 1984. In a broader sense though, this sort of War on x is very Orwellian I think because it's directing the public to scapegoat segments of the population (drug users, muslims as potential terrorists) and blame them for their ills, and see themselves as perpetually at war with members of their own society, in the same way that in 1984 those guilty of vague, abstract crimes became the enemy and worthy of hate, simply by virtue of a government pronouncement.

War has become normalised and part of everyday life, with the implication that as we are at war special rules apply and the enemy, as designated by the government, deserves no mercy because we are engaged in an existential struggle.
