The respiratory system works like an apparatus to handle and process the inhalation of oxygen and exhalation of water vapor and carbon dioxide. The addiction for tobacco is actually one related to the nicotine and tar content in the tobacco.

 The craving only gets more aggravated with indulgence and becomes very painful, emotionally and physically, when an attempt is made to give it up. Nevertheless, the damage caused by the habit has far-reaching effects and even after going through smoking cessation withdrawals, it takes the respiratory tract years to totally rehabilitate.
