“…Of these studies, nine studies found significant associations between PTSD diagnosis and nicotine dependence. In particular, six found higher levels of nicotine dependence among individuals with PTSD compared to those without PTSD (Mitchell, Van Voorhees, Dennis, et al, 2012;Vrana et al, 2013;Vrana, Calhoun, Dennis, Kirby, & Beckham, 2015) or any other psychiatric condition (Baggett et al, 2016;Beckham, Calhoun, Dennis, Wilson, & Dedert, 2013;Wilson, Dedert, Dennis, et al, 2014), and three found that diagnosis of PTSD was associated with increased risk for nicotine dependence (Cougle et al, 2010;Greenberg et al, 2012;Roberts, Chikovani, Makhashvili, Patel, & McKee, 2013). It should be noted that the proportion of individuals with other psychiatric conditions in these studies was extremely low (≤6%).…”

“…The lowest rate of PTSD among current users of tobacco products was found in a study involving cigarette smokers from the general population (3.0%) (Zvolensky et al, 2014) whereas the highest rate of PTSD among current users of tobacco products was reported in a study of homeless cigarette smokers (66.3%) (Baggett et al, 2016). Results are graphically displayed in Other studies explored rates of current or history of PTSD among current or former users of tobacco products.…”

“…Twenty-nine studies reported the prevalence of prior or current PTSD among current or lifetime users of tobacco products (Alexander, Ali, McDevitt-Murphy, et al, 2017;Baggett, Campbell, Chang, Magid, & Rigotti, 2016;Farris, 2015;Farris, 2016;Farris, Vujanovic, Hogan, Schmidt, & Zvolensky, 2014;Farris, Zvolensky, Beckham, Vujanovic, & Schmidt, 2014;Flanagan, Hakes, McClure, et al, 2016;Garey, Cheema, Otal, et al, 2016;Greenberg, Ameringer, Trujillo, et al, 2012;Hermes et al, 2012;Hruska, Bernier, Kenner, et al, 2014;Jessup, Dibble, & Cooper, 2012;Lawrence et al, 2009;Lombardero et al, 2014;Lopez, Konrath, & Seng, 2011;Lopez & Seng, 2014;Mahaffey, Gonzalez, Farris, et al, 2016;Mathew et al, 2015;McClernon, Calhoun, Hertzberg, et al, 2013;Roberts et al, 2015;Sawchuk et al, 2012;Sawchuk, Roy-Byrne, Noonan, et al, 2016;Van der Velden et al, 2007;Weber, Boggero, Carlson, et al, 2016;Young-Wolff et al, 2014;Zvolensky, 2014;Zvolensky, Farris, Schmidt, & Smits, 2014;Zvolensky, Vujanovic, Miller, et al, 2007). Of these studies, twenty-five explored rates of PTSD among cigarette smokers, two among smokeless tobacco users (Hermes et al, 2012;Sawchuk et al, 2012), and the other two among users of other combustible tobacco products (Roberts et al, 2015;Van der Velden et al, 2007).…”

“…Eleven studies found PTSD was not associated with heavier use of tobacco products (Baggett et al, 2016;Baschnagel et al, 2008;Beaudoin, 2011;Beckham et al, 2007;Cook et al, 2017;Farris, 2015;Marshall et al, 2008;Marshall et al, 2009;Mitchell et al, 2012;Ritter, McCauley, Amstadter, et al, 2011;Wilson et al, 2014). Of those studies, ten found that individuals with PTSD do not smoke a higher number of cigarettes than those without this condition, and one study reported that a diagnosis of PTSD was not associated with cigarettes smoked per day.…”

Posttraumatic stress disorder (PTSD) and tobacco use are prevalent conditions that co-occur at striking rates in the US. Previous reviews examined prevalence and factors associated with cigarette smoking among individuals with PTSD but have not been summarized since 2007. Moreover, none explored rates and factors associated with the use of other tobacco products. This study aimed to systematically review the most recent literature examining the comorbidity of PTSD and tobacco use to provide prevalence rates, as well as summarize the literature exploring other factors associated with tobacco use among individuals with PTSD. Studies were identified using a systematic search of keywords related to tobacco use and PTSD within the following databases: PubMed, PsycINFO, Web of Knowledge, CINAHL, PsycARTICLES, and Cochrane Clinical Trials Library. The studies included in this review (N = 66) showed that the prevalence of current use of tobacco products in individuals with PTSD was 24.0% and the rate of PTSD among users of tobacco products was 20.2%. Additionally, results demonstrated that individuals with PTSD present with high levels of nicotine dependence and heavy use of tobacco products, as well as underscore the importance of negative emotional states as a contributing factor to tobacco use among individuals with PTSD. It is imperative that future studies continue monitoring tobacco use among individuals with PTSD while also assessing factors identified as having a prominent role in tobacco use among individuals with PTSD. These findings also demonstrate the need for more innovative approaches to reduce the pervasive tobacco use among individuals with PTSD.

“…From April to July 2014, we used time-location sampling [ 21 – 24 ] to conduct an in-person survey of homeless adult smokers at 5 high-volume BHCHP clinical sites. Our sampling design and survey procedures are described in-depth elsewhere [ 25 , 26 ]. Participants were required to be proficient in English, ≥18 years old, current cigarette smokers, and currently homeless.…”

BackgroundThree-quarters of homeless people smoke cigarettes. Competing priorities for shelter, food, and other subsistence needs may be one explanation for low smoking cessation rates in this population. We analyzed data from two samples of homeless smokers to examine the associations between subsistence difficulties and 1) smoking cessation readiness, confidence, and barriers in a cross-sectional study, and 2) smoking abstinence during follow-up in a longitudinal study.MethodsWe conducted a survey of homeless smokers (N = 306) in 4/2014–7/2014 and a pilot randomized controlled trial (RCT) for homeless smokers (N = 75) in 10/2015–6/2016 at Boston Health Care for the Homeless Program. In both studies, subsistence difficulties were characterized as none, low, or high based on responses to a 5-item scale assessing the frequency of past-month difficulty finding shelter, food, clothing, a place to wash, and a place to go to the bathroom. Among survey participants, we used linear regression to assess the associations between subsistence difficulty level and readiness to quit, confidence to quit, and a composite measure of perceived barriers to quitting. Among RCT participants, we used repeated-measures logistic regression to examine the association between baseline subsistence difficulty level and carbon monoxide-defined brief smoking abstinence assessed 14 times over 8 weeks of follow-up. Analyses adjusted for demographic characteristics, substance use, mental illness, and nicotine dependence.ResultsSubsistence difficulties were common in both study samples. Among survey participants, greater subsistence difficulties were associated with more perceived barriers to quitting (p < 0.001) but not with cessation readiness or confidence. A dose-response relationship was observed for most barriers, particularly psychosocial barriers. Among RCT participants, greater baseline subsistence difficulties predicted less smoking abstinence during follow-up in a dose-response fashion. In adjusted analyses, individuals with the highest level of subsistence difficulty had one-third the odds of being abstinent during follow-up compared to those without subsistence difficulties (OR 0.33, 95% CI 0.11–0.93) despite making a similar number of quit attempts.ConclusionsHomeless smokers with greater subsistence difficulties perceive more barriers to quitting and are less likely to do so despite similar readiness, confidence, and attempts. Future studies should assess whether addressing subsistence difficulties improves cessation outcomes in this population.Trial registrationClinicalTrials.gov: NCT02565381.
