I think you are being unclear here. I took your remark on abstinence to be a reference to abstinence only sex education, as I think most readers did. If you are asking how we can help teens with a nicotine addiction to break it then there are a variety of ways that have been shown to work in helping someone break addiction, so schools, parents, and healthcare providers can support those.
I don't see how the article disagrees with what I just said. I really think you are being unclear here in what you are trying to say. Are you asking specifically what should schools due to assist nicotine users to quit, or something else?
