There's a metric know an "Disability-adjusted life year", or DALY, that tries to quantify this: https://en.wikipedia.org/wiki/Disability-adjusted_life_year.

And your point about social alcohol is well taken. I have the luck of being a lightweight with drinking, so usually a glass of cider is enough for me, and with the right people it's always a good time. On the other hand, lots of people my age (young adults) tends to drink multiple pints of beer multiple times a week. They should at least be aware of the tradeoff they're making.
