Kay Francis as Baroness Teri says "In the morning, a cocktail. In the afternoon, a man. In the evening, Veronal." Veronal is an old brand name of barbital pills, the first commercial barbiturate. It was prescribed as a sleep aid from 1903 until the 1950s.
During the robbery, William Powell as The Robber insists that the jewelry store owner, Mr. Hollander, smoke one of his (The Robber's) "cigarettes". Soon, Mr. Hollander is giggling and singing. When asked what he gave him, The Robber says "A harmless smoke. He'll awake in the morning fresh and happy with a marvelous appetite." The next day, the Police President refers to it as a "drugged" cigarette. It's obvious to the audience that the "cigarette" was marijuana (or marijuana-laced) even though it is never mentioned by name.
