I am one of those people who never touched a cigarette in his life. But trust me when I say that addictions come in many shapes and forms. So huge respect for you quitting and not falling back. Keep it up.
By the way do you have a tip to convince others from stopping to smoke? I don't want to annoy them but I still want the best for these people. I know you have to convince yourself. But maybe a bit help from outside wouldn't hurt?
