Denying healthcare to smokers is impractical  There are several reasons why limiting access to healthcare for smokers could prove impractical. Ultimately they surround the issue of how you define who is a smoker. One man might have chain smoked for 20 years but given up for a year, since a bill limiting access to healthcare for smokers was passed. Meanwhile, another might have been smoking cigarettes now and again just for the past year. Who would be prioritized if the two were on a waiting list for the same operation? If the law penalizes anyone who has ever smoked then it would not provide nearly as strong an incentive to stop smoking. But, if the law does not penalize anyone who has smoked, then choosing whom to punish would seem quite arbitrary. Furthermore, what is stopping people from simply lying about how much/whether they smoke? They might not show any obvious signs of being a smoker. Even if they do, they could claim to have given up, work around fumes or be a victim of passive smoking.
