blame your brain.
Scientists at the University of Massachusetts Medical School say there are specific areas
of the brain responsible for those nasty withdrawal symptoms: headaches, irritability and nausea.

as addictive as *** and ***. (Via Howcast)
Even after I had my heart surgery (FLASH) I still smoked after that. (FLASH) This is
after I had six bypass surgeries. (FLASH) It's difficult." (Via CDC)
Those University of Massachusetts researchers gave mice water laced with nicotine for more
than a month. They then analyzed how their brains formed addiction. (Via Voice of America)
What they observed was an area in the middle of the brain — called the interpeduncular
nucleus — harbored activity that stimulated withdrawal symptoms.
See — when a person smokes, nicotine travels pretty quickly to the brain. It attaches itself
to a receptor that releases a chemical called dopamine, which makes people feel good. (Via

The researchers say their study gives them hope that if they can learn how to basically
deactivate the neurons in that region of the brain, they could probably help more people
kick the habit. According to the CDC tobacco use causes more than 5 million deaths every
year.
