Genes impact on ability to quit smoking


(CNN)--Having trouble quitting smoking?

Well, researchers say that may be another thing you can blame on your parents.

A new study finds nicotine addiction may be genetic.

Researchers at the University of Colorado at Boulder looked at the smoking patterns of nearly 600 pairs of twins.

More than 360 were identical twins.

Researchers found 65 percent of identical twins quit within a two-year period of each other.

Only 55 percent of fraternal twins did the same.

Researchers say the findings suggest a genetic component at play since identical twins share the same D-N-A.
