I like the scene with Tomlin's teenage son, when she's stressing about getting a promotion at her job from her sexist boss.
He says, "Mom, you've got to relax. I'm gonna roll you a joint."
She replies, "Josh, you know how I feel about that. Besides your grandmother would pitch a fit if she even hears you mention the word marijuana."
Josh: "She doesn't understand moderation. You're the one who keeps saying harm springs from excess. I'm talking about one joint."
Tomlin's character takes the joint, and proffers it to her colleagues played by Fonda and Parton, telling them, "We could have ourselves an old fashioned ladies' pot party." Fonda's an innocent, recent divorcée who pronounces it "really good pot" after the gigglefest that follows.
It's a scene that harkens back to Easy Rider (1969) in which her brother Peter turns on the innocent Jack Nicholson. It took women a little longer to get there, but we did. The ladies bond over the experience, and soon concoct a way to get what they want in the workplace. In a later scene Fonda announces to her ex-husband that she smokes marijuana as part of her awakening.
As an extra treat, the film features VIP Sterling Hayden as the company CEO who sweeps in to finally give the dastardly boss (Dabney Coleman) what he deserves.
Decades later, the movie was just about the only example a recent New York Magazine article could find of women smoking pot together on film, in a world where only "every once in a while you’ll get a Meet the Fockers–style mockable hippie-mom type."
9-5 was written and directed by Colin Higgins, who also wrote Harold and Maude (1971), in which an 80-year-old woman turns a young man onto pot (and life).
