You know, Why People Difficult to Stop Smoking?

A new study published in the journal Biological Psychiatry found that the habit of smoking can reduce the thickness of the human brain.

Researchers compared the thickness of the cortex on volunteers, both smokers and who had never smoked, who have no medical or psychiatric illness, was quoted by the Times Of India. The cortex is the area of the brain that is responsible for many important functions, including language, information processing, and memory.

The result is stunning. People who smoke thinned cortex in the left middle orbitofrontal. People who smoke more frequently, according to the study, depletion of cortical networks will be increasingly obvious.

These findings show, with thinning of the cortex, then the risk of becoming a drug addict rose, even she will increasingly become heavy smokers.

"Because of the thinning, it will be associated with impulse control, reward processing and decision making. This might explain how someone can become addicted to nicotine," said Simone Kuhn, one of the researchers.

Kuhn added, "In further studies, we plan to explore the rehabilitative effects of quitting smoking on the brain."
"The current findings indicate that smoking may have a cumulative effect on the brain," said John Krystal, MD, Editor of Biological Psychiatry at Yale University, who revealed this finding also highlights the importance of targeting young smokers to stop smoking.
