I see various posters and signs and advertisements all over the place here regarding drugs (and even “drags”), and almost every single one seems to have something about it that portrays the idea of promoting, as opposed to opposing, drugs.
The natural phrasing seems to be, “No, don’t do that. Do this.” And so, we have the natural adjustment in my brain of, “No! Drug!” to, “No, don’t do that! Do drugs!” or, “No, don’t do that! Drug!” (And then, is it meaning yourself or others?)
I know that I am silly. This in no way changes that I am using legitimate logic here, and these posters are kind of hilarious. 😛
