Link between genes and smoking addiction

An Interesting Breakthrough

Researches have shown that there is a significant connection between smoking and genes. Namely, people who have these certain genes are more likely to become smokers. These genes tend to be connected with a person's nicotine receptors enabling him or her to become a passionate, even heavy smoker. What is more, for people with this gene, smoking usually comes at an early age and stays throughout their lives. They become smokers somewhere before the age of 17, increasing their cigarette capacity, evolving into an extremely unhealthy habit until they become a full grown adults. However, these same researches came to another interesting conclusion claiming that people who start smoking after the age of 17 have smaller chances of developing an addiction.

How Does This Happen?

As mentioned above, these genes influence the cell activity in our organism. Of course, this impacts those cells which are nicotine receptors. Thus, once nicotine gets to the organism of a person with this gene, his or her cells experience changes, sending different signals to the brain, triggering an addiction. Therefore, people who possess this gene are more likely to develop this kind of an addiction, and are far less likely to be able to stop it. Nevertheless, this genetic situation does not make one more prone to become a smoker. Rather, as long as this person does not start smoking, he or she will not develop an addiction. Later, if the person does start smoking, his or her proneness to various diseases connected with smoking is increased.

A Shocking Fact

During this research, which encompassed around 3000 people, there were children involved as well. Shockingly, there were many of them who started smoking before they reached the 8th grade, while, until the 10th grade there was a frighteningly large number of children indulging in this activity. Subsequently, these tests have shown that these young smokers, if they happen to have the gene in question, will surely become adult smokers as well, and will, most likely, never stop smoking. Until a way of bypassing this genetic phenomenon has been found, the best cure is not smoking at the first place. So, keep your children away from cigarettes by setting up a right example yourself. This addiction has already taken too many lives. Therefore, we should not simply ignore it further on. Instead, we should rise above the addictive poison and choose a healthy and long life instead.
