Yup the secret addictive agent is nicotine. They had an article about the addictiveness of the stuff in McClean's I believe. Apparently companies that manufacture food can add limited amounts of addictive drugs like nicotine to thier food. Now I know why I was still satisfied with a coffee and no smokes when I first quit smoking. Gimme an extra large 4 and 4 and I'm one happy camper!
