I have lived around smokers my entire life. I occasionally smoke cloves (on rare occasions) or hookah (also on rare occasions) but every smoker I have ever lived with that has pets does the same exact thing. They smoke OUTSIDE! It is simple! Just because someone smokes doesn't mean they shouldn't be allowed to have pets. It just means they need to make changes in the way they smoke as in only smoking outside, smoking out an open window, etc.
