I don't think it worked. I was floored by how much smoking I saw on a recent trip to Europe, by young people of all. Scary slogans on the packs, no effect. Cigs are barely a thing in the states now, you are kind of a low caste pariah if you smoke, but I guess vaping and cannabis picked up the baton. I am an ex pack-a-day smoker myself, but quit about 10y ago. Don't crave cigs or the smell, but do crave nicotine.
