I'm not entirely sure this is the right forum. The amount of lobbyists make it political enough anyway. Move it if necessary.

This is pretty big, and the ramifications could be very far reaching. And I know many people who would be all to glad to kick the habit.

small area of the brain nestled inside the cerebral cortex might explain why smoking is such a hard habit to break.
A new study of 69 smokers with brain injuries showed that those who had damage to the insula often quit smoking suddenly and effortlessly, suggesting that this particular area could be a target for future therapies to help smokers quit.
Naqvi and his colleagues found 69 additional patients with brain damage, all of whom had been smokers before the damage occurred. Nineteen of the participants had brain damage involving the insula, 13 of these had quit smoking, and 12 of them had done so quickly and easily.
While some of the other patients also quit smoking, those with damage to the insula were more likely to have quit immediately and without anguish.
The insula's function seems to be to take information from other parts of the body and translate that into feelings such as fear, disgust, anger and sadness, along with desires and cravings.
Although some imaging studies have shown that this region of the brain is activated by drug-related cues, "the insula has never really been examined closely for its role in addiction," Naqvi said.
So far, the thought is just a theory, but the finding may help smokers quit using, for example, sensory replacements for smoking such as cigarettes without nicotine.
And, depending on what other research turns up, focusing on the insula may help people give up other addictive behaviors as well, the researchers added.
