I admit to being an ex smoker, so I have limited sympathy for those who
claim they cannot quite. While I used to enjoy the smell of cigarettes
I have to wonder if there is not something they add to tobacco to make
smell particularly bad. As more and more places are going smoke free I
see people standing outside their homes to smoke, and people in cars
tend to hold the butts out the window. They obviously know that the
smoke stinks, but they keep doing it.
