Compare this to ~5% of cancer related death attributable to alcohol use.
It's just not even an accurate comparison.
To be honest though? I am willing to bet that cost to healthcare system for alcohol related illness is outpacing that of smoking related illness. Cirrhosis of the liver is a very costly disease when it gets close to end stage.
but of course the vast majority of people that drink on saturday night do NOT end up in A&E.
What? Afaik alcohol is pretty well known to increase risks of several cancers in population. Individual response to alcohol is of course a much more complex topic with genetics affecting a large palette of physiological and neurological responses to alcohol. For populations - alcohol is a health risk. For individual - the narrative is far more nuanced (more risk for some than others etc).
