Maybe it is because smoking directly effects the people around you?
A. I don't smoke.
B. People smoking outdoors many dozens of meters away from others has zero effect on non-smokers.
I mean, think about it, man. It generally takes hard-core smokers many decades to develop their cancers. That's 30-40 years of sucking that shit directly into their lungs, maybe 10 drags/cigarette times 20-40 cigs daily. Even if we go with the lower figure (which I think is about typical for most addicted smokers), that's 73,000 times a year a typical smoker sucks the shit directly into his/her lungs. Over 30 years, that's almost 2.2 million direct from cig filter to lung draws.
I've lost the figures I used to have on-hand, but that's about the equivalent of a non-smoker sitting a meter away from such a smoker, non-stop, for sixty years before the non-smoker exhibited even one-ONE HUNDREDTH the lung damage the smoker sustained.
My figures might be wrong -- my memory isn't what it used to be

-- but it doesn't take much imagination or logic to put two and two together. To be sure, second-hand smoke is harmful ... but it takes MASSIVE exposure, and over many years at that, to make a measurable difference. People these days talk about walking within 10m of someone smoking will make them have coughing fits, stinky clothes and all manner of other outright horseshit.
I freely admit I'm glad to live when I do, but where were all of these second-hand cancers and whiners during the obnoxious smoking and drinking excess of the early to mid-60s? (Yeah, I've watched Mad Men

)
Again, my point isn't to defend the quarter or fifth of the population that smokes cigarettes; rather, I have the foresight to recognize that, once they are sufficiently demonized, the liberal "good-doers" among us will shift their focus onto, among other things,s "grossly obese" bodybuilders who carry 10% bodyfat or less.
Fellas, get over your hatred for people smoking cigarettes. Most of our hottest actresses are HUGE smokers. Charlize Theron, Eva Longoria, Olivia Wilde, Kate Winslet, Vera Farmiga, Virginie Ledoyen, Eva Green, Evan Rachel Wood, Britney Spears, Lindsay Lohan, Kate Beckinsale, Kat Heigl, and even sweet-as-pie Anne Hathaway -- all of them are on-record for either regretting quitting and/or absolutely LOVING smoking cigarettes.
Gross? Perhaps to some, but I don't give a fuck. If Beckinsale, Heigl or Hathaway wanted to make time with me, I'd light their every fucking cigarette by striking a match off my dick
