There are several reasons. First, medical researchers have shown that secondhand smoke, that is, the smoke from other people's cigarettes, causes cancer and other health problems. Third, I'm slightly allergic to smoke; therefore, my nose stuffs up when I smell tobacco smoke. If the smoke were car exhaust or burning trash, we would put out the fire and open the windows to get rid of the smoke. Second, it stinks. The smoke drifts away from the smoker and fills the room. However, the right of people to breathe pure air must always be put before the right of smokers to pollute that air. Whenever I smell strong tobacco smoke when lI'm in an enclosed space such as a room, train, or aircraft, I begin to get angry. Even if l am not sitting close to the smoker, my hair and clothes pick up the smell. Aml saying that all smoking should be banned? Of course not. Smokers have a right to smoke.
