Praise be to Allaah.
The things that do not break the fast include things that enter the body through absorption via the skin, such as creams, lotions and skin patches used to administer medicinal or chemical materials such as these patches which are used to treat the disease of smoking. Fear Allaah with regard to your body and do not cause it harm through this habit of smoking which is haraam (forbidden) according to shareeah. The Prophet (peace and blessings of Allaah be upon him) said: and verily, your body has a right over you. We ask Allaah to help you to give up this filthy habit and to protect us and you from all evil. May Allaah bless our Prophet Muhammad and grant him peace. And Allaah knows best.
