We know smoking MT an be deadly and causes cancer, yet millions of people continue to light up because they just can’t kick the habit. A new study shows something in the brain may make it harder from some to stop. Michelle Leone has been smoking for 20 years She’s tried to quit before.
“I’ve tried to go cold turkey, I have tried the gum, the nicotine gum both without success.”
A new study finds genetics may make it more difficult for some people to stop smoking. Researchers at the University of Pennsylvania say that some smokers have more receptors in the brain associated with rewards and emotions .
“Some people are born with receptors in the brain for nicotine that are actually part of the pleasure reward system of the brain and that these receptors bind to nicotine differently,” says Dr. Edward Eden, Director of Pulmonary, Critical Care and Sleep Medicine, St. Luke’s-Roosevelt Hospital Center.
Scientists say that could make it harder for some smokers to quit.
Forty-seven million Americans smoke and nearly half of them try to quit each year. Researchers hope their findings will lead to new treatments to help smokers.
“We might one day be able to provide specific medications that will attach to specific receptors in the brain and block these receptors from activating,” says Dr. Eden.
For now, Leone is cutting back on the number of cigarettes she has every day.
“The next thing that I would like to conquer in my life is to quit smoking,” adds Leone.
She hopes with will power and discipline., she can put cigarettes out for good this time.
Smoking cigarettes kills more Americans than alcohol, car accidents, suicide, AIDS, homicide, and illegal drugs combined, according to the American Cancer Society.
