Well established ways of conduction medical studies that dont depend on doctor quirks. They can establish a mathematically significant correlation. Correlation doesnt establish causality.
Doctors tend to be actually heavy smokers, from my experience. I have talked about this with a couple of them and they say that it helps them facing the stress of their everyday duties - even though they are aware of the health risks.
In the U.S. at least, doctors smoke at a much lower rate than the general population. It might be that they stand-out more when smoking if you know that they are physicians.
a lot of them are borderline or full blown alcoholics too. this stems from the job they do - depressing, stressful, often under-appreciated. they know the effects of addictions too well, but at the end, they are still only human beings like rest of us...
