I did some research for you...
Got Milk?
The RR for lung cancer from ETS [secondhand smoke ed.] exposure among never smokers is approximately 1.3 [Hackshaw et al., 1997].

Subjects reporting consumption of whole milk 3 or more times daily had a 2-fold increase in lung cancer risk compared to those who reported never drinking whole milk (RR = 2.14).

Secondhand smoke causes lung cancer in nonsmokers There is no safe level of exposure to secondhand smoke.

So what is the safe level of exposure to Milk?
Don’t get me started on any of this at this time of night!
