Are there any nicotine products besides regular cigarrettes and certain E cig juices that are kosher for Pesach. For example lozenge or gum?

ב"ה Shalom, In order to answer you, I actually took a walk to our local pharmacy to verify available products. The pharmacist could not find any nicotine products kosher for Pesach, so her suggestion was to use a nicotine patch. The patch would be ok, since if there is Chametz in it, it is not edible even for a dog, therefore one may benefit from it. (שו"ע תמב, ב; מ"ב י). All the best. Have a happy and Kosher Pessach
