I happen to think that the puppet masters are into drugs for at least 2 big reasons . . .
the money . . . partially to fund their plush bunkers and the purported deeply buried tube trains between them. . . .
and
to identify more ‘useless eaters’ to exterminate to get the population down to 200 million that the critters have convinced them is necessary to save the human race and the planet.
Add “control” to that and you are pretty much spot on.
