      Do you consider passive smoking is more dangerous than active smoking? Why?

    Answer:

                      Passive smoking can be equally dangerous because it exposes the persons to the same harmful effect of smoke. Passive or second hand smoking means being in the same room or place, where someone is smoking and getting exposed to smoke in the surrounding air. Once inhaled, the smoke can trigger release of mucus in the bronchioles that blocks the air ways. This induces coughing. But prolonged exposures can lead to bronchitis emphysema, respiratory tract infections and eventually lung cancer.
