Only tangentially related, but I am continually astonished by the absence of any sort of social norms surrounding cigarette butt disposal. I have (otherwise environmentally conscious!) friends who smoke, and I've personally witnessed them flick their cigarettes into gutters and on streets. As a serious question, without judgment: are there any smokers on HN who can explain the phenomenon?
From the article: In one focus group cited in industry documents, smokers said tossing their butts to the ground was “a natural extension of the defiant/rebellious smoking ritual.”
It comes from the same mindset as diesel truck owners rolling coal on cyclists and people in hybrid cars, and destruction of public property (park benches, trash cans and such).
Some people either just don't give a shit about other people, or are actively antagonistic.
