If you've been on every patch, chewed every gum, tried out hypnosis, watched the cancerous lung slideshow put together by your health teacher, and still can't seem to quit smoking, a recent study may provide a reason why. Your ability to quit smoking could be determined by your genes. Thanks, mom.
A recent study published in Translational Psychiatry has established a link between quitting smoking and DNA among caucasians. Researchers looked at 22 studies taking into account 11 ,075 subjects in and found the DRD2/ANKK1 gene showed certain variants can cause a person to be more or less likely to give up smoking. Basically, people with the A2/A2 genotype are more likely to quit smoking, while those who carry A1/A1 or A1/A2 are less likely to quit.
But again, the connection could only be firmly established in caucasians, which means for a whole lot of the world there was not a strong connection. Still, "It's in my DNA" is fun to say and a good way to rationalize your mid-dinner smoke breaks during the next holiday get-together. Just make sure to take deep breaths between words, since, well, smoking's bad for you.
