I don't personally agree with such imposed restrictions on 'lifestyle choices' - whether achieved by 'bans', draconian taxation or whatever. What, given the realities, one might contemplate is denying people treatment at NHS cost for the consequences of poor 'lifestyle choices'. However, to attempt that would be to open a massive can of worms. For a start, establishing a causal relationship between those 'choices' and diseases would be next-to-impossible in individual cases - people with almost ideal 'lifestyles' can, and do, develop diabetes, heart disease, cancer etc. More to the point, where would one stop? Would NHS-funded treatment be denied to anyone who had chosen to participate in sports etc. etc. ... and, probably the biggest issue, would our society really accept a situation in which people were 'left to die' if they were being denied NHS treatment and couldn't afford any other?
