A problem with modern medicine and government policy.
This all starts from the perfectly respectable desire to not have people die unnecessarily early. Along with hygiene, medicine and health and safety we all, in modern countries live longer, healtheir lives than our ancestors.
Unfortunately we have now moved from the 'small changes making massive differences' part of the curve to the 'incremental improvements' part of the curve where the accompanying consideration has to be 'quality of life'.
I have never smoked, rarely drink (just don't feel the desire usually) and have never taken any psycho-active substances but those are MY choices. What is the point spending an extra ten years on the planet if you spend a large part of that craving those bacon sarnies you can't have, or just wishing you could 'pop out for a drink with the lads'.
As others have said (better than me) living is risky. Perhaps the real problem is that people are not educated in assessing risk/reward especially in the context of unavoidable background risks.
On the other hand perhaps the real problem is the Daily Mail and its ilk.
