Smokers pass on faulty DNA to future generations

Los Angeles: Women who smoke during pregnancy not only put their babies health at risk but also that of future generations, say researchers at the University of Southern California.

In a recent study, scientists found that smoking may permanently alter DNA, which is inherited by siblings. For example, they discovered that the grandchildren of smokers were more than twice as likely to suffer from asthma.The researchers studied 338 children who had developed asthma before the age of five.
