Preston Curve adjusted for tobacco users

In the U.S, or U.S. and Canada only;

I know it isn't hard science (maybe not science at all), but has anyone removed all
smokers (or maybe tobacco users) fom the data and recalculated the Preston Curve?

Where would I find those adjusted studies, summated?

Or if you already know what's the general take from them?

Thanks,

I think that's interesting to know.
Let's see if anyone else can provide this.
