The manufacturers of NoSmoke claim that their product reduces smokers' cravings for cigarettes. However, in a recent study, smokers given the main ingredient in NoSmoke reported no decrease in cravings for cigarettes. Thus, since NoSmoke has only two ingredients, if similar results are found for the second ingredient, we can conclude that NoSmoke does not reduce smokers' cravings. The argument above is flawed in that it ['illicitly presumes that a claim must be false because the people making the claim are biased', "overlooks the possibility that NoSmoke helps people to quit smoking in ways other than by reducing smokers' cravings for cigarettes", 'illicitly presumes that a whole must lack a certain quality if all of its parts lack that quality', 'relies on a sample that is likely to be unrepresentative']
