Are nicotine pouches placed between the lip and gum considered to break the fast during Ramadan, knowing that they help in quitting smoking and their juices are not swallowed?

Nicotine pouches, placed between the lip and gum, contain addictive nicotine. Medical studies and reports have warned of their health risks to the heart, immunity, and brain. They can cause dizziness, headaches, and nausea. There is no evidence of their effectiveness in helping people quit smoking. Therefore, if their harm is proven, they are forbidden. Their use is prohibited for a fasting person because they dissolve and some of their contents are swallowed after mixing with saliva. As for nicotine patches, their use is permissible and does not affect the fast.
