Why it is Difficult for People to Quit Smoking


quit smokingA new study published in the Biological Psychiatry journal 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 those who had never smoked, who have no medical or psychiatric illness. 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. Cortex of people who smoke thinned in the left middle of the orbitofrontal. In people who smoke more frequently, according to the study, the depletion of cortical networks will be quite clear.

This findings shows that with the thinning of the cortex, the risk of becoming a drug addict rise, they will become more 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, , according to the Times Of India.

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.
