Tobacco smoke is contaminated with more than 7,000 toxic substances such as tar, arsenic, nicotine and cyanide. Over 60 of these chemicals are carcinogenic ingredients. What is lesser known is that tobacco also contains radioactive materials; polonium-210 and lead-210, which can accumulate in the lungs of the smokers for decades, leading to lung cancer [2]. Tobacco smoke can cause many other types of cancer including cancers of the mouth, larynx (voice box), pharynx (throat), oesophagus (swallowing tube), stomach, pancreas, kidney, bladder, cervix, colon/rectum and myeloid leukaemia [2]. In addition, it increases the risk of premature death, pulmonary and respiratory disorders such as chronic bronchitis, coronary heart disease, and stroke and even carries profound health risks to an unborn child.

The majority of us believe that taking Vitamin C will help us build a strong immune system. But if you smoke, you are likely to need more of this important vitamin to fight the harmful effects of smoking.
