I have been working in the medical field for a few years and I was very surprised to find the number of nurses and other healthcare workers that smoke. I found this statistic on a few different websites that I found interesting.
"the number of registered nurses who smoked dropped from 11 percent in 2007 to 7 percent in 2011, the study found. That's an overall decrease of 36 percent, and nearly three times higher than the 13 percent decline in smoking among the general population during the same period."
