Roseanne tries to quit smoking in "Stressed to Kill" and complains to Jackie how their entire generation was encouraged to smoke by nearly every character on TV:
Roseanne: It's true, Jackie. Lucy smoked, Desi smoked, Ward smoked, Make Room for Daddy smoked, Gomez and Morticia smoked, Maxwell Smart smoked, 99, the Chief, Hymie—and he was a robot, but he smoked. Patty smoked. Jackie: But Cathy didn't.
Roseanne: I know, but they made her into a huge nerd. Rob smoked, Laura smoked, Buddy, Sally, Jerry, Millie smoked. I don't know about Samantha, but both Darrins smoked.
