I should add to this. By specifying two x-variables, controlling for
whether or not they smoke, you need to think about which two (continuous)
x-variables you wish to scatterplot against each other and whether or not
that relationship will differ substantially between smokers and
non-smokers. Some quick and easy correlation runs will help here,
obviously.

I hope all that helps.
