There are realistic and practical ways in which the policy of denying healthcare to smokers could be carried out. Smoking is a habit that has clear and demonstrable physical effects, which often correlate with the regularity and longevity of the habit; doctors are trained to recognize such symptoms and do not need patient confirmation. Furthermore, if the bill made it quite clear that healthcare was to be denied to present smokers, the hypothetical presented by the opposition is easily negated. The goal of such a bill would to be to ensure that both smokers gave up the habit and non-smokers did not take up the habit. In this case, the man taking up smoking is in the wrong and is acting contrary to the law. He would have little room for complaint.
