STUDY: Nicotine Measured From Toenail Clippings Predicts Risk Of Lung Cancer

Wouldn't it be easier just to ask whether a person smokes, how much, and for long?

This dubious research was done at the Univ of San Diego (see here for the media report).  I hope we taxpayers didn't fund it.

What could possibly have led these scientists to analyze toenails for nicotine?

One comment in the media article said that some of the men with the highest levels of nicotine in their toenails were non-smokers, and speculated that they were exposed to second-hand smoke.  Does that make sense?  That some people are nicotine magnets?

On the contrary, such a finding would make me question whether the measurement was accurate or meaningful.
