Similar applies to smoking. There are the 'obvious' cases in which

Which is supported by clear scientific evidence.

But there are probably far more cases in which smoking has had

For which there is no credible evidence whatsoever. I could make the claim
that "there are probably far more cases in which eating marmite sandwiches
has had consequences which contributed to demise" on that basis.
