Well, if that one woman was shown as "cool" i think it would be a problem. But look at her. She is some old woman, with a terrible voice, she could care less about anything that is happening. All of those bad qualities, and then they add her smoking a cigarette. I think if anything, it's showing smoking in a bad light.
Now if Milo, or Kida were smoking rare drugs only found in Atlantis or something, that would be bad.
