Dr Who and the Daleks sweet cigarettes were 1964 tie-in food products manufactured by Cadet Sweets.
Despite the name, it was not a tie-in with the feature film Dr. Who and the Daleks, which was at the time still a year away, but rather with season 1 of Doctor Who. Also, they were not "sweet cigarettes" in the early 21st century sense of being a cigarette sweetened with flavouring. They were a completely non-tobacco product — a candy cigarette that was entirely consumable but shaped like a cigarette. Moreover, the box that was roughly the same dimensions as a British cigarette pack. It's unclear how the product may have tasted as, strangely, the first of the product's stated ingredients given on the rear of the pack was "Skaro" — the name of the Daleks' homeworld.
