He’s a heavy smoker, going through 60-70 cigarettes a day
In the recent movies, the only thing Bond smokes are the bad guys, but in the Sean Connery era, he was seldom without his cigarette case.
The novels reveal that he has his cigarettes custom made by Morland of Grosvenor Street. He’s even got a specific blend of Balkan and Turkish tobacco, a gunmetal case that holds 50 of them, and a black oxidized Ronson lighter that he carries everywhere.
