In the early episodes of the series, he is often seen smoking cigarettes. Following the 1964 Surgeon General's on smoking, cigarette commercials were banned from American television in 1971, and public awareness of the dangers of cigarette smoking increased dramatically during the 1970s. To cut down on his own habit, Kojak began using lollipops as a substitute. The lollipop made its debut in the Season 1 episode "Dark Sunday", broadcast on December 12, 1973; Kojak lights a cigarette as he begins questioning a witness, but thinks better of it and sticks a lollipop (specifically, a Tootsie Pop) in his mouth instead. Later in the episode, Kevin Dobson's character Crocker asks about the lollipop and Kojak replies, "I'm looking to close the generation gap." Although Kojak continued to smoke, as he was frequently seen lighting a cigarillo, the lollipop eventually became his identifying characteristic; in fact, when the series debuted a new opening montage in season five, Kojak is seen both lighting a cigarillo and popping a lollipop into his mouth.
