Abstract

        The hypothesis is that if the smokers with a fast metabolism, then they will have a greater craving for cigarettes. Also this will be able to tell them if they are at risk of cancer because of smoking

          The dependent variable will be the compound or the caffeinated drink that the volunteers will digest.  The independent variable will be the volunteers who will have different phenotypes or metabolic profiles.

          Based on our test and the literature that we have read we came to our conclusion that our hypothesis was accepted.
