Summary:
Cigarette smoking and heavy alcohol use cause epigenetic changes to DNA that reflect accelerated biological aging in distinct, measurable ways, according to research. The researchers estimated biological age using a previously validated epigenetic "clock" , calculated the difference between biological age and chronological age, and assessed the relationship between tobacco and alcohol use and premature aging.
