Scientists have found that while male smokers showed a greater number of nicotine receptors in their brains compared to non-smokers, the situation was different for women in whom even non-smokers have as many receivers as smokers.
Usually, when an individual uses tobacco, the number of nicotine receptors in the brain increases. These receivers pick up the nicotine, which reinforces the habit of smoking and tobacco addiction.
“When calculating the number of receivers by gender of the smoker, there is a big difference,” said one of the authors of this study, Kelly Cosgrove.
These discoveries are crucial, since most people who want to quit are using therapies nicotine replacement (gum, transdermal patches). However, it seems that women would be more efficient to use different techniques like behavioral therapy, relaxation exercises or medications without nicotine.
To reach these conclusions, the researchers performed a brain scanner 52 men and 58 women, half of whom were smokers. Radioactive material has to make visible the nicotine receptors.
The results of this work were published in the journal Archives of General Psychiatry.
