I am using nicotine mouth pouches for a healthier way of getting nicotine. There is no tobacco in them, just nicotine. They are like a small tea bag you put between your gum and lip and the nicotine is absorbed through the gum over a period of about 2 hours. Then the bag is discarded. My question is are there kashrut concerns .
Thank you for your question.
If there are flavorings, etc, in the ingredients then it the source of the flavorings etc. would have to be verified, because you are sucking and eating the flavors.
