Heavy Drinking May Change DNA, Studies Report

Heavy drinking may change DNA, leading to increased craving for alcohol, reports a study out of Rutgers University.

Binge and heavy drinking may trigger a long-lasting genetic change, resulting in an even greater craving for alcohol, according to a Rutgers-led study in the journal Alcoholism: Clinical & Experimental Research.

“We found that people who drink heavily may be changing their DNA in a way that makes them crave alcohol even more,” said Distinguished Professor Dipak K.
