I use these even after I stopped smoking cigarettes.
I've been using these for about 2 years now. I've disclosed this to my doctors who've told me that it's harmless and quite normal. Please do not take this as medical advice and check with your own doctor. U prefer the cherry flavor because the cinninman flavor leaves stinging feeling on the the tip of my tongue but only after the several boxes. What I don't like is that dissolve into a white powdery like substance (tastesty) and when you talk or lick you lips it gets all over your lips and then dries they. You can't feel it's so it's easy to forget that's it's there. One of my doctors asked what it was and realized that everyone saw it and I looked ridiculous lol. I would recommend them.
