the fact is that it bothers people. a courteous person would take steps to not let something as trivial as a cigarette be a deliberate offense to others. its pretty easy these days to stay away from it.
as for being stored, not any more or less so than most other contaminants in the air. liver function is key in this regard.
and as for your reaction to it, how do you know there is not a psychological component? or, in other words, how can there not be? there is in my thinking. my bias is that i love tobacco. always have. probably always will.
i think both of our biases are on the table. we must take personal responsibility for them.
