I believe that smoking should not be banned, not because I'm a smoker, but because of the lesson that America has learned due to Prohibition in the 1920s. Prohibition was when the U.S. government passed the 18th amendment: the banning of alcohol consumption, manufacturing, and sell. Soon later, tons of people started to smuggle alcohol for the men to drink and made a lot of money. Wondering what was so good about alcohol, women and children joined the bandwagon.
It's kind of like, the more laws there are, the more people would want to break them. And alcohol and smoking are like money to some people; they can't live without them. If there was ever a law created to ban sneezing, coughing, or anything like that, people would still do it anyway; they can't help it.
