“…Much of this work documents that low DT increases risk of very early lapse behavior, including within the first several hours or days of abstinence (e.g., Abrantes et al, 2008; Brown et al, 2002; Kahler et al, 2013). Associations of low DT to faster relapse latency generally extend across various measures, including breath holding duration (Brown et al, 2002; Brown et al, 2009; Hajek, 1991; Hajek, Belcher, & Stapleton, 1987; c.f., Steinberg et al, 2012), persistence on a CO 2 challenge (Brown et al, 2002; Brown et al, 2009), and persistence on psychologically stressful and frustrating tasks (Brandon et al, 2003; Brown et al, 2009; Brown et al, 2002; Cameron et al, 2013). They have also been documented in several populations, including a mixed sample of smokers with and without schizophrenia who were provided cessation counseling and pharmacotherapy (Steinberg et al, 2012).…”
