Filter by:The purpose of the study is to examine the effects of continuous theta burst stimulation (cTBS) on different forms of cognitive control in adults who smoke cigarettes, and to determine if the location where cTBS is delivered may help smokers reduce or quit smoking. Participation in the study will take 3-weeks over 4 visits, with a total time commitment of approximately 12 hours.
Characterize effects of relighting on smoke toxicant deliveries and subjective smoking measures. This will be a within-subject comparison in a single experimental group of 30 smokers who report engaging in relighting behaviors. We will assess smoking intensity for relit and non-relit (i.e., smoked continuously without relighting) cigarettes in the natural environment and will conduct in-clinic measurements of smoking topography and subjective responses for relit and non-relit cigarettes. Information on relighting patterns and smoking topography collected from each participant will be used to compare machine-measured smoke yields of key harmful constituents when their usual cigarettes are smoked with and without relighting. Hypothesis: Relit cigarettes will produce higher levels of toxicants than non-relit cigarettes.
Smoking can damage lung functions as a result of high carbon monoxide and low hemoglobin oxygen carrying capacity in the blood. Smoking between young people continues to increase, which can cause respiratory function problems and lung diseases at an early age. In the studies, it has been seen that smoking may reduce the oppression and exercise ability.
The goal of this project is to better understand the relationship between tobacco/nicotine and cannabis using behavioral economics during a tobacco/nicotine quit attempt. All participants will receive tobacco/nicotine cessation treatment (smoking and/or vaping treatment) for 12 weeks. To qualify, participants must be between the ages of 18-25 and use tobacco products (smoke cigarettes and/or vape nicotine) and use cannabis (in any form). Participants do not need to be interested in quitting cannabis/marijuana to qualify. This study is being conducted by the Medical University of South Carolina. All procedures are conducted remotely and there is no in-person visits are needed.
ABSTRACT Aim: Our study aimed to determine the approaches of our physicians to the smoking habits of their patients other than those with pulmonary diseases. Method: Patients examined in different outpatient clinics of our hospital will be asked 7 questions about the doctor's approach to smoking habits. 1) Do you have information about smoking cessation clinic? 2) Has your doctor asked if you smoke? 3) Did he suggest you stop using it? 4) Did he inform you about the relationship between smoking and your disease? 5) Did he provide information about smoking cessation outpatient clinic services? 6) Have you ever thought about quitting smoking after your doctor's briefing? 7) Did you quit smoking after your doctor's briefing?
PRECESTO is a randomized, double-blind, cross-over trial on 34 smokers who do not want to stop smoking and get high satisfaction from smoking. The primary objective is to assess efficacy of NFL-101 in reducing the positive reinforcing properties of cigarettes compared to placebo measured by the modified Cigarette Evaluation Questionnaire (mCEQ) "Smoking Satisfaction" (items 1, 2, and 12) subscale.
The study will recruit an anticipated 256 adults who currently smoke cigarettes and report a willingness to try switching to alternative, non-combustible products. Participants will be randomized to receive either e-cigarettes or nicotine pouches for a duration of 4 weeks and to 1 of 4 possible regulatory scenarios within products where flavor availability is either menthol and tobacco/unflavored available or tobacco/unflavored only available, and nicotine concentration is either higher (5% e-cig, 6mg pouch) or lower (2.4% e-cig, 3mg pouch). Participants will return for bi-weekly research visits (in person or remote videocall) to complete measures for study aims. Participants will complete a final follow-up at Week 6 to assess maintenance of cigarette reduction and willingness to continue using products once they are no longer provided. The investigators expect to observe which products and constituents lead to greater smoking reduction.
Anxiety sensitivity, reflecting the fear of bodily sensations, is a risk factor for the maintenance and relapse of smoking. This study is designed to address the question - is a smoking cessation intervention personalized to high anxiety sensitive smokers and adapted for implementation by the YMCA effective among racially/ethnically diverse samples?
Nicotine remains a major cause of health problems in the US and around the world. Insight into the behavioral changes induced by nicotine use may help advance the understanding of the mechanisms underlying the maintenance of nicotine addiction and thus the important factors involved in the quitting process. Pavlovian bias is a phenomenon that includes an approach tendency toward rewarding cues and an action withdrawal tendency in response to punishments. This phenomenon may be particularly relevant to nicotine users. The current study will use an experimental, within-subjects, repeated-measured design to investigate whether acute nicotine administration influences individual Pavlovian bias in nicotine users. By recruiting participants from the University of Southern California (USC) community and contacting participants of previous nicotine-related studies of the Addiction and Self-Control Laboratory at USC, the investigators will enroll forty adult nicotine users in the study. Participants will come to the lab twice after a 10-hour nicotine fast. At each lab visit, participants will undergo a vaping session prior to completing the study tasks. The content of the e-liquid in the vape will vary by nicotine content: the vape will either contain nicotine or not. Subsequent to vaping, participants will complete a version of the Go/No-Go task which will measure their individual levels of Pavlovian bias. The investigators will compare performance on the task across the two conditions within each participant: on- and off- nicotine, after controlling for nicotine withdrawal and nicotine tolerance. Based on past research on nicotine, the researchers anticipate that acute nicotine administration will be associated with higher levels of Pavlovian bias, compared to the off-nicotine condition. Specifically, two patterns are expected to arise: a higher likelihood of making a go-response in the "win reward" condition and a higher likelihood of making a no-go response in the "avoid losing" condition, regardless of whether it is a "go" or "no-go" trial. Participants will also complete a measure of their working memory capacity. The investigators will conduct exploratory analyses for the relationship between different nicotine conditions and working memory capacity.
In a crossover study, experienced electronic cigarette users will vape 3 different forms of nicotine: natural (derived from tobacco), synthetic, or a 50:50 mixture of both natural and synthetic. The investigators will compare nicotine metabolism, cardiovascular effects, patterns of self-administration, and participants' feelings of craving/withdrawal and enjoyment.
