According to Ian Fleming’s books, James Bond was a heavy smoker, consuming 60-70 cigarettes a day. By my quick calculations, that means Bond smoked a new cigarette about every 15 minutes.
Bond was also loyal to a specific brand: Morland cigarettes. These were custom cigarettes created specifically for him by Morland & Co. of Grosvenor Street from a blend of Balkan and Turkish tobacco. They had three gold rings around the butt.
These were real cigarettes which one could buy, and which Fleming himself smoked. They were sold as the “James Bond Special No. 1”. However, you can’t buy them anymore since the company went out of business soon after Fleming’s death.
