    Carcinogens cause cancer.
    CO has a higher affinity for haemoglobin than oxygen and so binds preferentially.
    Nicotine is an addictive substance. It is a stimulant and so increases blood pressure. It also causes people to be addicted to smoking which causes many health problems such as those above.

    From what I remember: cigarette smoke contains carcinogens that mutate the genes of abnormal cells. The cells start to divide uncontrollably to give cancerous growths or tumors. The Bronchi becomes blocked by cancerous growths. The symptoms; Coughing up blood, weight loss and shortness of breath.
