“…Also, in daily smokers, the combination of PD and more intense nicotine withdrawal symptoms, compared to either individuals with PD with less withdrawal symptoms, smokers without PD or nonsmokers with PD, is also associated with greater subjective and physiological reactivity and slower recovery from a biological challenge (Leyro & Zvolensky, 2013, 2014; Zvolensky et al, 2004). Among individuals with PD, there is a significant association between vigilance to bodily sensations and health related concerns (Schmidt, Joiner Jr, Staab, & Williams, 2003; Starcevic et al, 2009), which may in part explain why smokers with PD are more sensitive to nicotine withdrawal symptoms (Jarvik et al, 2000; Shadel, Niaura, Brown, Hutchison, & Abrams, 2001). In smokers with PD, this hypervigilance may increase the expectation that their smoking is negatively affecting health.…”
