I managed to get a fake vaccine cert (QR code) last year to go on a fab sun holiday! :-) even had a mask exemption letter I made for the airline to go maskless :-)

I am talking about a general approach to encourage people to avoid harmful lifestyle choices by rewarding those who do and penalising those who don't. There will always be exceptions which demand common sense judgements.

Someone who is overweight would not be likely to be recommended to take up jogging at a level to produce a heart attack before being encouraged to lose weight via a sensible diet. Heart attacks are emergencies. Emergencies are always a priority.

Revenue from any harmful behaviour is not a reason to avoid trying to reduce that behaviour. Getting people fit and active would likely produce more anyway.

That the NHS is always under pressure is no reason to accept making that pressure worse when it can, and should, be avoided.

Won't work. Person A gave up smoking 15 years ago so gets treatment before Person B who gave it up 10 years ago and both after Person C who's never smoked.
Using this logic why should someone with seven kids get more child support than someone with two when it was their choice to have them.

Having lots of children does result in community support via child support payments and added pressure on the school system and is a personal choice.
If smokers pay into the NHS they're entitled to the same time constraints and treatment as everyone else.

More? No one is asking for more; just not less.

I wasn't aware that people have lots of kids to benefit society.

If they need extra treatment due to smoking related disease then it certainly is more.

People don’t have kids to benefit society anymore that they go to work themselves to do so. It’s just a fact that it does.
