Are you a pregnant women, want to quit smoking and still find it difficult to stop smoking? If that is you, you are not alone. A new study has found the link between genes and smoking. The “addictive gene” explains why some women find it so difficult to stop smoking during pregnancy. According to the findings appearing in the journal of Human Molecular Genetics, the “addictive gene” in pregnant women is associated with a lower chance of quitting despite considerable social pressure to stop smoking. This gene is a specific genetic variant which is associated with the nicotine receptor. The study was carried on 2500 women who smoked before getting pregnant. The success rate was 28% in pregnant women with the gene compared to 31% in pregnant women without this gene. The researchers investigated whether the genetic variant that influences increased cigarette consumption also had a role to play as an extra hurdle to quitting smoking during pregnancy. The results of this study explain why some pregnant women find it so difficult to stop smoking. This finding is quite significant because it will pave way for further research on the treatments to help pregnant women who want to stop smoking but find it harder then other people who want to quit smoking.
