    researchers at Yale
    University. Researchers
    used brain-scanning
    technology to compare the
    nicotine receptors of 16
    smokers who had
    abstained for four days
    with scans from a group of
    16 nonsmokers. They
    found that the density of
    common nicotine receptors
    was higher among smokers
    during early abstinence,
    contributing to withdrawal
    symptoms. “Nicotine

    factor associated with
    relapse,” said lead author
