Cigarette smoking by definition is “inhalation of the gases and hydrocarbon vapors generated by slowly burning tobacco in cigarettes”. Globally 80,000 to 100,000 kids start smoking every day. The World Health Organization (WHO) has compiled worldwide smoking statistics which are quite sobering:

  • About a third of the male adult global population smokes.
  • Smoking related-diseases kill one in 10 adults globally, or cause four million deaths. By 2030, if current trends continue, smoking will kill one in six people.

Study was conducted in a university of Pakistan to identify the prevalence of cigarette smoking among students. The result revealed that, 23% of students (31% male and 6% female) were classified as a current smoker which is a high percentage.  Results indicated that students in general are open towards cigarette smoking. Generally smoking is considered as an addiction derived from the environment. Many researches have shown that smoking behavior is influenced by both genetic and environmental factors. Many years of twin and adoption studies have demonstrated that heritability is at least 50% for both smoking initiation and smoking persistence.

A recent study has revealed that Smokers leave a chemical marker of their addiction in their DNA. Researchers found sites in the DNA that were chemically tagged as a result of smoking. The tags can be detected in lung tissue, and could be used to measure increased risk of cancers of the lung, breast and bowel.

But it can’t justify someone who says “I can’t quit smoking it’s in my genes”. Researchers have shown that one can stop smoking even if it is inherited as genetic factors do play a part in smoking behavior; this is only a small part. Environment, if structured in a way that it inhibits smoking, plays a part too. A belief is a very strong psychological incentive, and can be a strong influence on stop-smoking treatment. So while you smoke keep it in your mind that you are going to pass it on to your offspring.
