Well, the obviously better analogy is drinking. Just as people in the U.S. once thought smoking was essential to the enjoyment of all kinds of human activity, so now do people think this way about alcohol, to enormous social detriment.

Interestingly, the anti-smoking crowd won by convincing the public that absolutely any amount of smoking is so harmful to yourself and (crucially!) everyone around you that consuming even the smallest amounts is unconscionable. That's obviously untrue, but it's a very successful narrative (so successful that I suspect most of you will bristle at the suggestion that it's not true).

This was crucial because it convinced people that: 1) no, moderation isn't acceptable; and 2) every bit of intake is harming somebody else.

A truthful campaign couldn't have made these two arguments and so wouldn't have been as successful.
