“…Indeed, epidemiological (Grant, Hasin, Chou, Stinson, & Dawson, 2004;Lasser, et al, 2000), community (Hayward, Killen, & Taylor, 1989) and clinical (Himle, Thyer, & Fischer, 1988;McCabe et al, 2004;Pohl, Yeragani, Balon, Lycaki, & McBride, 1992) studies have found that daily cigarette smoking is more common among those with anxiety and depressive psychopathology compared to those without such problems. Other studies have found that smoking, particularly at higher rates, increases the risk for developing and maintaining clinically significant anxiety and depressive symptoms (Breslau & Klein, 1999;Breslau, Novak, & Kessler, 2004;Goodwin, Lewinsohn, & Seeley, 2005;Isensee, Wittchen, Stein, Höfler, & Lieb, 2003;Johnson et al, 2000;Korhonen, et al, 2007;McLeish, Zvolensky, & Bucossi, 2007;Steuber & Banner, 2006). There is also evidence to suggest daily smokers experiencing high levels of anxiety and/or depressive symptoms tend to experience more severe withdrawal sensations (Breslau, Kilbey, & Andreski, 1992), resulting in more difficult and less successful quit attempts (Anda et al, 1999; Zvolensky, Gibson et al, in press).…”
