Is There a Genetic Link to Smoking Addiction

It has been announced recently, scientists have found proof of genetic link to smoking addiction. They said these genes variations have made some people more likely to get hooked to cigarettes and some smokers and former smokers more prone to lung cancer. This study was done on people of European descent only.

Half of all smokers will eventually die from lung cancer or other smoking related illness. Interestingly, men are more likely affected although the number of women with lung cancer is catching up. Smoking-related diseases worldwide kill about one in 10 adults, according to the World Health Organization.

Smoking and passive smoking greatly increases the risk of lung cancer, causing nine out of ten cases. 

The research shows that there are some smokers who are even more vulnerable to lung cancer because of their genetic profile. With some inheriting variants from both parents having a 70 to 80 percent higher risk compared to that of smokers without the genetic variants.

This could possibly lead to some kind of screening test and customized treatment for smokers trying to kick the habit but could have its fallback.
People who are found with these variants may find it harder to get health or life insurance.
And if this happens, what is this going to lead to? Additional insurance premium that you have to fork out because you are a smoker!

I guess genetics also point to gender and studies have indicated that women find it more difficult to quit because they are more likely to smoke due to emotional reasons; to manage moods and control weight while men are less emotional smokers.

However, statistically, studies have also shown that women are more likely to quit when they are pregnant than at any other point in their lives. Perhaps the responsibility of parenthood is sinking in. But of course, there are those that continue to smoke despite all the health warning about what smoking can do to their unborn child.

Young women smokers also have higher stroke risk compared to their non smoking peers. The study was done on women age 15 to 49 was published in Stroke: Journal of the American Heart Association.
Interestingly, stroke is more common in men than in women. However, more than half the total stroke deaths occur in women and at all ages, more women than men die of strokes.

You must be crying foul and unfair while riding this, why does a woman have higher smoking related risk? I guess it’s all in the genes.

Nevertheless, with all these talk about genetic link to smoking addiction, could it be the explanation that some people can quit whereas others fail?
Why some smoke without being addicted…

Well… don’t let this talk about genetic link to smoking addiction be an excuse why you fail to quit or why you are addicted. Cut out the BS! You haven’t try yet!
