Nineteen participants had smoked previously with low smoking pack years (median 1.7 years).
Nineteen (29%) participants had previously smoked, however with relatively low smoking pack years of 1.7 (IQR 0.5 - 5).
In general, the study population was highly educated (80.7% had attended at least some college) and reported low smoking rates (60.2% had never smoked).
In New York, despite our strong smoke-free air laws and historically low smoking rates, more than 25,000 people still die from tobacco-caused disease annually while another 2,500 deaths are attributable to secondhand smoke exposure.

And the group of firefighters who were not exposed had a lower rate than the general population, which the researchers said may be a result of their overall physical fitness and low smoking rates.
To this end, they must be aware of the problem and have, as a group, a low smoking prevalence.
