Filter by:Cigarette smoking constitutes the greatest preventable cause of mortality and morbidity in the US. The most critical period for long term success of smoking cessation appears to be in the first 7 days after the quit date. A metaanalysis of 3 pharmacotherapy trials revealed that abstinence during the first 7 days was the strongest predictor of 6 month outcomes (n=1649; Odds ratio: 1.4, P <0.0001; Ashare et al. 2013). Prodigious relapse rates during this first week of smoking cessation are likely due to behavioral and neurobiological factors that contribute to high cue-associated craving and low executive control over smoking. The long term goal of the research is to develop evidence-based transcranial magnetic stimulation protocols to facilitate abstinence during this critical period.
The goal of this research is to understand the potential impact of two new FDA strategies to ensure the availability of safer Alternative Nicotine Delivery Systems (ANDS) and to reduce the nicotine content in combustible cigarettes to non-addictive levels. Specifically, this research will examine how well ANDS and very low nicotine cigarettes (VLNCs) can work alone or in combination with the current strategy of providing a safe source of nicotine via nicotine replacement medications to reduce use of combustible cigarettes, in real-world settings. The investigators will enroll 180 daily adult smokers who are not planning to quit smoking within the next 30 days into this mixed design study. Participants will be randomly assigned to one of three levels of the between-subjects factor: 1) VLNC cigarettes; 2) Juul e-cigarettes (with nicotine); or 3) no alternative product. Participants receiving an alternative product (VLNC or e-cigarettes) will be asked to use it for 4 weeks (Weeks 1 through 4). During Weeks 2 and 4 all participants will be asked to switch from their cigarettes to use only study products (i.e., Juul e-cigarettes, VLNCs, or no alternative product) and to use either an active nicotine or placebo patch (the within-subjects factor), provided in double-blind fashion and counterbalanced order. During Weeks 1 through 4, participants will use a smartphone to record, in the moment, each time they use their own cigarettes or any alternative product. For a random daily subset of use events, participants will complete additional questions about the internal and external context of their use (e.g., affect, any restrictions on smoking) and their response to use (e.g., withdrawal alleviation, taste, satisfaction). Using these data, the investigators will also examine the effects of these products on the rewarding value of smoking and possible mechanisms driving such behavior (e.g., withdrawal alleviation, satisfaction, taste). This research will provide critical information regarding the potential impact of providing cigarettes with non-addictive levels of nicotine and safe ANDS, with or without nicotine replacement, in real-world settings on smokers' use of their usual cigarettes and other outcomes. Information on the short-term effects of products that could be accessible in the future will provide data that could inform regulatory policy decisions regarding the public health impact of safe ANDS and non-addictive cigarettes.
Chronic Obstructive Pulmonary Disease (COPD) is caused primarily by smoking and smoking cessation is the first-line treatment for slowing disease progression. Despite this, nearly 50% of COPD patients continue to smoke following diagnosis. Smokers with COPD report high rates of co-occurring conditions - nicotine dependence, depression, and anxiety - which serve as barriers to quitting. The current study will pilot test a behavioral intervention designed to target the common psychological factors underlying these co-occurring conditions and foster smoking cessation among COPD patients.
Approximately 60 chronic smokers with bipolar disorder, schizophrenia or schizoaffective disorder who are motivated to try to quit smoking will be randomized to receive smoking cessation treatment with the FDA-approved medication, varenicline, delivered either a) at its standard dose and titration schedule (half of the participants) versus b) at a lower dose and slower titration schedule (the other half), for 12 weeks. All smokers will choose a target quit date sometime between 8 to 35 days after starting the medication. All participants will receive ten 30-minute sessions of a behavioral treatment called Acceptance and Commitment Therapy (ACT). Participants will be followed for an additional 12 weeks off study medication. The major endpoint is the feasibility of combining ACT with the different dosing strategies. Investigators will also conduct a blood test that measures the breakdown of nicotine in the body to explore whether that measure influences treatment response and side effects.
The primary objective of this study is to determine whether the application of transdermal nicotine patches in critically ill patients after major surgery with nicotine abstinence condition is associated with a lower incidence of delirium.
This study will examine the short-term cardiovascular (CV) effects of e-cigarette device power in a randomized, crossover clinical and behavioral pharmacology study of experienced adult e-cigarette users (N=21). The specific aim is to determine the impact of e-cigarette power on nicotine pharmacology, systemic exposure to toxic volatile organic compounds (VOCs), and short-term cardiovascular effects.
