There are many articles on the facts on smoking illnesses and death but this, from our NHS that spends £11 billion per year tackling the effects, is good enough:
https://www.nhs.uk/common-health-questions/lifestyle/what-are-the-health-risks-of-smoking/

And there is no article that can prove a link between smoking and many of those ailments. And that was my point, its unproven. I never said smoking didn't cause cancer and blood clotting, I just said nobody has yet been able to prove it.
There is circumstantial evidence in the form of a correlation between risks of some diseases and smoking, but I have just found a correlation between obesity and watching Love Island. Yet I doubt watching trash TV causes obesity.
Speaking of obesity, the NHS website swears blind that being obese will cause diabetes, but keeps quiet that both types are hereditary. Yes, you are more likely to get type 2 if you are a fat slob (watching Love Island, according to my
correlation linked fact from above), but only if you have the faulty genes to start with. Unless the leaflets from the (NHS) diabetes clinic are lying, of course.
Everything needs a tag line now, to get through to the ear more dumbed down, stupid. Like "Speed Kills" banded about by the old bill/dvla/etc several years ago, but had to stop because it fell foul of ASA, after it was discovered that nobody had ever died of speed, only acceleration.
Anyway, it was, as said previously, a throw away comment, and there are far more important things to going on than arguing about a non-issue.
