Cigarette smoking is the leading cause of preventable mortality in the United States, yet less than 10% of smokers making a serious quit attempt remain abstinent from cigarettes 1 year later, and outcomes from gold-standard behavioral interventions leave much room for improvement. As such, in the context of a Stage-I randomized controlled trial (RCT), this study will examine (1) treatment characteristics and delivery, treatment integrity, dropout, and acceptability, (2) smoking outcomes such as lapse, relapse, and abstinence measures, and (3) changes decision-making that result from a novel intervention informed by behavioral analysis and social cognition.
The primary purpose of our study is to conduct a pilot, practice-based intervention focused on increasing adherence to the 6As for youth ages 11 through 17 years. The 6As are: (1) "Anticipate" (future use), (2) "Ask" (about tobacco use), (3) "Advise" (advise the patient to quit using tobacco), (4) "Assess" (the patient's readiness to quit using tobacco), (5) "Assist" (by setting a quit date, providing materials on quitting tobacco, providing tobacco cessation medications, and referring the patient for additional services and/or counseling) , and (6) "Arrange" (by re-contacting the patient after their quit date and arranging a follow-up visit).
This study will determine whether or not patients who use a Nicotine Replacement Therapy (NRT) patch prior to their by-pass surgery are more likely to be smoke-free 6 months after their surgery and have fewer post-operative complications
A placebo-controlled trial to determine whether recent ex-smokers with COPD who successfully stop smoking after taking varenicline are less likely to relapse back to smoking if they continue using varenicline for a further 12 weeks
The investigators aim to examine the effect on smoking cessation rate by showing stroke patients who are active smokers images of their strokes.
A number of pharmacotherapies are available for smoking cessation in New Zealand including nicotine replacement therapy, bupropion, an antidepressant medication and varenicline. Of these, varenicline is the most effective, but also the most expensive. Varenicline acts like nicotine and stimulates nicotine receptors in the brain, but to a lesser extent, and simultaneously block nicotine binding to its receptors and thus reduces the rewarding effects of cigarette smoking. Cytisine (Tabex® and Desmoxan®) is a plant alkaloid and also acts in a similar way to varenicline but is significantly cheaper. It has been used for more than 50 years in some parts of eastern and central Europe as an aid to quit smoking, but is not approved for use in many countries such as New Zealand, Australia, the UK or the US. Randomised, placebo-controlled trials have shown that cytisine is more effective than placebo and nicotine replacement therapy (NRT)for smoking cessation. However there is a paucity of pre-clinical data on cytisine. In particular, there are limited data on the pharmacokinetic and the dose response characteristics of cytisine. Furthermore, the current dosing regimen recommended by the manufacturer is complex and has no clear basis in empirical research. Complexity of dosing has been shown to be a key factor in determining adherence. Therefore, a simpler regimen would likely maximise the effectiveness of treatment through improved adherence to the treatment regimen. The investigators therefore propose to undertake two studies to investigate the influence of dose, dosing frequency and dosing duration on the pharmacokinetics and tolerability of cytisine and cigarette craving in smokers.
Some individuals smoke with the perception that smoking helps control body weight. Smokers gain an average of as much as 10 pounds in the months following smoking abstinence, with heavier and more-dependent smokers gaining more weight. T The Mayo Clinic Nicotine Research Program will randomize 100 nondiabetic, overweight or obese adult smokers to active lorcaserin or placebo for 24 weeks; all of the subjects will receive open-label varenicline for 12 weeks. The purpose of this study is to assess the efficacy of a 24-week course of lorcaserin for decreasing weight gain after stopping smoking.
The purpose of this study was to compare the effectiveness of the high-intensity proactive service with the low-intensity reactive service at the Swedish National Tobacco Quitline (SNTQ). Our hypothesis was that the effectiveness is about 5% higher in proactive than in reactive service. The structured treatment protocol is a mixture of motivational interviewing (MI), cognitive behavior therapy, and pharmacological consultation.The standard process at the SNTQ is to offer the client a choice of callback (proactive service) or no callback (reactive service). In the present study clients were not offered a choice, but were randomized to proactive service on even dates and to reactive service on odd dates. Data are collected through postal questionnaires, one baseline and one follow-up after 12 months.
Cigarette smoking evokes major changes in the biology of the airway epithelium, the cell population that takes the brunt of the stress of cigarette smoke and the cell population central to the pathogenesis of chronic obstructive pulmonary disease (COPD) and lung cancer. The focus of this study is to identify the differences that two popular alternative nicotine delivery strategies, shisha and electronic cigarettes, have on the airway epithelium compared to cigarette smoking. We hypothesize that both alternative nicotine delivery strategies disorder airway epithelial biology, but in different ways than does cigarette smoking.
