I'm not sure this is entirely true - at least not in "high powered" occupations.

It's amazing, for example, how many doctors, lawyers, and professors smoke. Nicotine has a tremendous benefit to the nervous system and aids in concentration - much like caffeine.

In addition, the camaraderie among smokers is extremely beneficial to a career. When people go out together for a smoke-break, it gives them a chance to talk, interact, and network. And you might just be the mail-room clerk at your company, and find yourself offering the CEO a light.

Does smoking in excess have health risks? Sure. So does overeating, over-drinking, and driving too fast. Life's pleasures are best enjoyed in moderation.
