Smoking is definately gross! And very harmful to animals and people! I really hate it when people bring their pets in and the poor things reek of smoke. We have a sheltie that comes in and always smells like smoke, I feel so bad for him. I think if I were an animal having to be exposed to that, I would run away. That nasty smoke also affects their organs. You can see the degeneration on x-rays. They are so helpless, they didn't ask to be surrounded by nasty smoke all day!
