If you haven't quit smoking yet... there's even more reason to do so... a recent study found that it can create long lasting effects to d-n-a... which may increase the risk of chronic disease.

Researchers at the National Institute of Environmental Health Sciences studied d-n-a samples from nearly 16-thousand adults.
They found smokers had changes in over seven-thousand genes linked to cancer, heart disease, and stroke.
The good news is most genes recovered within five years of quitting smoking... but some genetic changes remained... even 30 years after kicking the habit.

A new survey of three-thousand adults reveals many are uninformed about electronic cigarettes.
Most agreed that e-cigarettes should be banned in places where smoking is prohibited ... but one-third still allow them to be used inside their home.
And while most knew e-cigarette vapor contains nicotine, about half did not realize using the devices around children exposes them to toxins.
and that using them indoors deposits nicotine on surfaces.

And despite smoking rates dropping among kids and teens in recent years ... that doesn't mean they won't smoke in the future.
A recent study looked at smoking susceptibility among youth ... which is a lack of commitment by non-smokers not to light up.
Researchers found smoking susceptibility has remained steady among white kids and teens ... and has increased among the Hispanic youth population.

Experts say these trends are concerning... because young people with this attitude are more likely to experiment with tobacco products.
