According to a European study published in the journal Biological Psychiatry , smokers suffer a thinning of the orbitofrontal cortex . Specifically, experiments show that the more cigarettes a person smokes per day and the longer they have been a smoker, the thinner their cerebral cortex is in this region. The thinning of the cerebral cortex has been linked to aging and reduced intelligence .
In addition, according to Simone Kühn, a researcher at the "Charite" Faculty of Medicine of the University of Humboldt (Germany) and co-author of the study, since the orbitofrontal cortex has been related to impulse control, reward, and intake of decisions , your weight loss can increase the risk of addiction. Consequently, smoking would have a cumulative effect on the brain that makes it increasingly difficult for chronic smokers to quit.
