Nothing good happens to the people around you when you smoke cigarettes. You run a big risk of offending a nonsmoker who can help or hurt your career. Even smokers dislike the smoke and ashes and butts and dirty ashtrays and smell of smokers.
In addition to all the well-known, well-published arguments against smoking, there are other specific business reasons not do so. Smoking wastes time. Smoking is a self-centered interest. To get ahead in business you have to think of others, their needs and wants, not yours. Smoking interferes.
Cigarette smokers are, or appear to be, controlled. Winners in business are in control.
Smoking cigars is OK . . . if you are alone or with friends. Smoking an expensive cigar in the purview of a corporate chieftain is a mistake. The corporate chieftain is a mistake. The corporate chieftain will see you as a pompous, as self-important, as having or spending too much money. If the boss gives you a celebration cigar, save it. You probably haven’t yet earned the right to smoke a victory cigar.
~ Jeffrey J. Fox, How to Become CEO (1998)
