You'd probably need to frame it in some financial way. For example, allow health insurance companies to deny coverage to smokers, and disallow public health insurance (like Medi-Cal) from insuring smokers. Unfortunately, this would likely be a literal slippery slope back down to allowing health insurance companies to deny coverage based on pre-existing conditions.
