Sherrie: Scientists now agree that nicotine in tobacco is addictive inasmuch as smokers who try to stop smoking suffer withdrawal symptoms. For this reason alone, tobacco should be treated the same way as other dangerous drugs. Governments worldwide have a duty to restrict the manufacture and sale of tobacco. Fran: By your own admission, "addictive" is broad enough to include other commonly consumed products, such as coffee and soft drinks containing caffeine. But of course the manufacture and sale of these products should not be restricted. The dialogue above lends the most support to the claim that Sherrie and Fran disagree with each other about which one of the following statements? ['The manufacture and sale of all drugs should be regulated by governments.', 'Coffee and soft drinks that contain caffeine should not be regulated by governments.', 'Scientists and governments have a duty to cooperate in regulating drugs to protect the public health.', 'Agreement by scientists that a substance is addictive justifies government restrictions on products containing that substance.']
