“…Tobacco addiction and chronic pain are both highly prevalent and co-occurring disorders that have been hypothesized to operate in the manner of a positive feedback loop, resulting in greater pain and the maintenance of smoking behavior (Ditre, Brandon, Zale, & Meagher, 2011; Zale, Maisto, & Ditre, 2016). Rates of tobacco smoking among individuals in pain (28%–68%; Goesling, Brummett, & Hassett, 2012; Michna et al, 2004; Orhurhu, Pittelkow, & Hooten, 2015; Patterson et al, 2012) far exceed those observed in the general population (18%; CDC, 2014), and smokers with chronic pain (vs. no chronic pain) are nearly two times more likely to meet diagnostic criteria for nicotine dependence (Zvolensky, McMillan, Gonzalez, & Asmundson, 2009).…”
