The things you find noodling around the internet. It began by looking up the actress /strongwoman Hope Emerson—best known for lifting Spencer Tracy off the ground in court in the 1949 movie Adam's Rib—after I watched her exclaim what sounded to me like "Smokin' Oakum!" throughout Westward the Women (1952). Oakum are the short fibers of hemp; generally they are not smoked. (It's possible she was saying, "smoke and oakum.")
Emerson, who made her Broadway debut playing an Amazon woman in Lysistrata in 1930, was nominated for an Oscar for her role as a sadistic matron at a women's prison in Caged (1950), for which the author Virginia Kellogg served time in four American prisons under false charges, as research.
Caged and anti-marijuana propaganda films were parodied in the 1977 SCTV skit, "Broads Behind Bars," in which Catherine O'Hara and Eugene Levy of TV's "Schitt's Creek" smoke pot, leading to her imprisonment and defiant downfall "from just one small stick of the stuff." Emerson's role was handled by John Candy in drag in the skit, which a title card mockingly says was "produced in cooperation with the anti-marijuana league of North America."
