People barely smoke anymore. What is it, like 5% of people with a college degree smoke and 5% of people under the age of 30 smoke?
Smokers these days are mostly composed of uneducated, poor, older people. Not to say that is good, but uneducated poor people do a lot of stuff that is killing them. Given the massive decline overall in this generation, I think smoking is going to be much lower on the list of lifestyle risks for uneducated poor people. Obesity is arguably a bigger concern I would say.
I don't remember the last time I saw someone in their 20s legit smoking a cigarette that wasn't at a party or something.
