It is common knowledge the smoking is the leading cause of preventable death. Still, millions of Americans continue to do it, and I believe that they have every right. Without getting into arguments about environmental tobacco smoke or the legal tobacco age, are cigarette companies ethical? Until the 1960s, American smoked without hesitation. In 1964 the surgeon general published a report that smoking tobacco can lead to lung cancer, and the controversy began.
I don't think that cigarette smoking should ever become illegal. However, I do think it is fair for the country to ban the sale of tobacco products to those under the age of 18, because it is much more dangerous at a younger age. I think it is fair to say that everyone knows cigarettes are bad, but I support the warning labels on cigarettes. In my mind it is immoral to sell a product that is potentially harmful to a person without making the potential effects clear. In 1984, Congress passed the Comprehensive Smoking Education Act that required four different warning labels to be rotated on tobacco companies product.
Whether or not a person chooses to smoke is a personal choice and I think it'd be unconstitutional to take that away from them even if it's harmful to them. In my opinion, the moral thing to do is warn every customer.
