This is a TV ad from 1949 that made me laugh. Especially where they ask, “What cigarette do you smoke, Doctor?”

In 2000, only 3% of doctors surveyed said they smoked cigarettes, 4% said they smoked cigars, 1% said they smoked a pipe, and 92% said they do not smoke at all.

General surgeons are the biggest smokers in our survey. More than 6 percent smoke cigarettes, while another 6 percent smoke either cigars or pipes. The highest cigar use was among ob/gyns—7 percent. Pediatricians and internists smoke the least.

Only 23% of the general public smoke cigarettes, according to the same survey.
