Temporal Dynamics of Smoking Urges
Background Understanding the relationship between different dimensions of nicotine cravings and smoking behavior is crucial for addressing nicotine dependence. This study examined how morning cravings and past-week cravings relate to nicotine intake, as measured by salivary cotinine, and the mediating role of cigarettes per day (CPD) and time to first cigarette (TTFC).Methods Data were obtained as part of the Pennsylvania Adult Smoking Study (PAS…
A Qualitative Exploration of Quitline Perceptions among African American and Hispanic or Latino Adults Who Smoke
Introduction Tobacco quitlines are efficacious, accessible, and cost-effective. While the prevalence of cigarette smoking remains higher among non-Hispanic White adults, the quit ratio has remained lower for African American (AA) and Hispanic or Latino (H/L) adults who smoke. The National Jewish Health Quitline (NJH QL) has sought to address whether current QL services provide effective and equitable tobacco cessation services. This study evaluat…
A Comparison of Mental Health Symptoms among Adults Who Vape Nicotine, Cannabis, or Both
OBJECTIVES: Dual use of combustible cannabis and nicotine is related to worse mental health symptoms (MHS); however, little is known about MHS among those who vape cannabis and nicotine. The current study aimed to determine if dual use of cannabis and nicotine vapes is associated with worse MHS compared to single use and to identify correlates of MHS for dual users. METHODS: = 492) who used nicotine or cannabis vapes in the past 30 days on stress…
Racial Differences in Nicotine Reduction
Introduction Tobacco regulatory policies are generally intended to apply to all segments of the population and to be equitable. Results from clinical trials on switching from commercial cigarettes to reduced nicotine cigarettes have included black populations but race-specific findings are not widely reported. Methods Data were pooled from two parallel randomized controlled trials of gradually reduced nicotine in cigarettes from 11.6 mg per cigar…
A Comparison of Vaping Behavior, Perceptions, and Dependence among Individuals Who Vape Nicotine, Cannabis, or Both
Background: Electronic delivery systems (e.g., vapes, e-cigarettes) are now popular modes of cannabis and nicotine administration that are often used by the same individuals; however, we still know little about dual nicotine and cannabis vaping. Materials & Methods: An online convenience sample of adult nicotine and/or cannabis vape users residing in the United States completed a 60 min survey on sociodemographic characteristics, cannabis and/or …
Tobacco Use Changes and Perceived Health Risks among Current Tobacco Users during the Covid-19 Pandemic
COVID-19 has become a global pandemic, with over 81 million cases worldwide. To assess changes in tobacco use as a result of the pandemic, we surveyed a convenience sample of current tobacco users between April and June 2020. The sample was taken from a tobacco user research registry ( n = 3396) from the Penn State College of Medicine in Hershey, Pennsylvania, USA. Participants who responded to the survey and were eligible for this study ( n = 29…
Characterizing nicotine exposure among a community sample of non-daily smokers in the United States
Our findings highlight the variability in nicotine exposure across days among non-daily smokers and point to the role of smoking context in nicotine exposure. The findings suggest the need to develop better assessment methods to determine health and dependence risk and personalized cessation interventions for this heterogeneous and growing group of smokers
Comparison between Gradual Reduced Nicotine Content and Usual Nicotine Content Groups on Subjective Cigarette Ratings in a Randomized Double-Blind Trial
In 2018, the United States Food and Drug Administration (FDA) issued an advanced notice of proposed rulemaking to reduce nicotine in tobacco products to produce a minimally addictive or nonaddictive effect, but there was a research gap in the subjective responses of reduced-nicotine-content cigarettes. We compared the responses of the modified cigarette evaluation questionnaire (mCEQ) and cigarette-liking scale (CLS) between the gradually reduced…
Socioeconomic differences in nicotine exposure and dependence in adult daily smokers
Among smokers, there was a relationship between lower SES and increased nicotine dependence, cigarettes per day and nicotine exposure, which varied by job type
Effect of Cigarette Rod Length on Smokers Switching to SPECTRUM Cigarettes
Objectives: Cigarettes vary in rod length but are generally thought of as a constant unit. In this study, we evaluated whether the rod length of participants' usual brand cigarettes affected their perceptions and smoking habits when switching to SPECTRUMs. Methods: Data were analyzed for 341 participants smoking their own brand cigarettes for one week and after switching to normal nicotine content (11.6 mg) SPECTRUMs for 2 weeks. Changes in perce…
Clinical trial recruitment of adult African American smokers from economically disadvantaged urban communities
This investigation evaluated the effectiveness and challenges of multiple recruitment methods, described as proactive, reactive, and combination methods, among adult African American smokers ( N = 527) from economically disadvantaged urban communities enrolled to test progressively reduced nicotine content investigational cigarettes. The study evaluated success using descriptive statistics to measure the volume of phone calls and percentage of el…
