I would like to ask about the patchs that are used for people who want to stop smoking. Are those ok to use during Ramdan or will they break the fast?
All perfect praise be to Allah, The Lord of the Worlds. I testify that there is none worthy of worship except Allah, and that Muhammad is His slave and Messenger.
Such patches are not among the nullifiers of fasting, since they are like the oil absorbed by the body.
The ruling of its use depends on the extent the harm this substance on the human body. In this regard the medical doctors should be consulted. If harm is confirmed, then using becomes forbidden.
Allah Knows best.
