at this point, I don’t think encouraging most adults to not smoke is a helpful thing.
I think that everyone who could easily quit, has already quit. Why in the world would anyone continue smoking these days? Not only are you endangering your health, but you’re also made into a social pariah, exiled to the doorways of buildings to partake in your habit.
those who still smoke are people with an overly strong addiction to smoking, and they require our compassion, support and, as Health and Yoshi and others said, professional help.
Young people are another story. They should be discouraged and perhaps even shamed into not smoking. I was fortunate that it only took two puffs of a cigarette when I was 18 years old to convince me that smoking was not for me, and I was never again tempted by it.
