At long last my son has come clean and admitted he's smoked for about 2 years. I was sure he was but he kept denying it, so it was really hard to help him. He now wants to stop and I want to help him. I've never been a smoker so don't know how it feels to have nicotine withdrawal. I'd love some advice please. Patches? Chewing gum? How does it all work and how can I best help him? He doesn't want to vape. Thank you in advance.
