Animated World of DC Comics: Superman teaches about smoking (1977)

From The All New Super Friends Hour, though the graphics you'll see come from when it was reissued in the 80's:

Superman (Danny Dark) is on patrol when he sees a high school baseball player dragging on a cigarette during the game. I don't think that was actually allowed back then, and it certainly isn't today, but, as this short illustrates, smoking is like a PDD (Performance Diminishing Drug), if you get my drift.
