Why Do Some Smokers Appear Healthier Than Others?
Researchers say genetics might be why deadly smoking-related diseases affect some people more than others.By Matt Moreno | September 28, 2015
The dangers of smoking cigarettes are well-documented, but why some people can smoke and stay healthy has remained somewhat of a medical mystery.
Now, a study out of the U.K. involving 50,000 participants indicates that's all thanks to genetics.
The study, funded by the Medical Research Council, found that many people who were able to ward off chronic obstructive pulmonary disease, or COPD, had a genetic mutation that strengthens the lungs and lessens the effects of smoking.
