Is it obligatory to continue giving charity to a woman who is a provider and whose husband spends most of his money on smoking and cafes, or is it sufficient to only give her payment for cleaning?

Do not stop giving charity to this woman as long as she is in need. The fact that her husband smokes does not preclude the permissibility of giving charity to her. She can be advised to keep the money for herself and her children and not to give it to her smoking husband. It is permissible to give charity to a smoker himself, unless the giver of charity is certain that he will use the money for smoking.
