This study plans to investigate whether using electronic cigarettes (e-cigarettes) or skin patches containing nicotine affects switching from smoking conventional combustible (burning) cigarettes.
This is an observational, crossover study that will be examine use behaviors, chemical exposures, and biological effects of SREC compared to TC use in subjects confined to a research ward setting.
Using a 2x2 randomized factorial design, we will conduct a statewide field trial in Missouri to compare the relative and combined effects of these two strategies for augmenting an existing, evidence-based tobacco quitline program. Among 2000 low-income smokers, half will receive standard Missouri quitline services and half will receive new Specialized Quitline services targeted to this group. In each of these groups, half also will receive calls from a trained navigator to help them address unmet Basic Needs and the accompanying psychological distress that act as barriers to smoking cessation.
The primary purpose of the current study is to test the effect of providing users of automated web-based smoking cessation interventions with the option of negotiating and re-negotiating the quit date.
The purpose of the trial is to test the adjunctive effect of adding a lapse management system to a best practices web- and mobile smoking cessation program.
Electronic cigarettes are battery-powered vaporizers which have a similar feel to tobacco smoking. They do not produce cigarette smoke but rather an aerosol, which is frequently referred to as vapor. E-cigarettes are marketed as less harmful alternatives to smoking. Use and awareness of these devices has grown exponentially in recent years, with millions of people currently using them. The benefits and risks of electronic cigarette use are uncertain. There is no research on the acute oral effects of electronic cigarette in the scientific literature and no hungarian epidemiological survey has been performed in this topic. Regulation of electronic cigarettes varies across countries in the European Union, ranging from no regulation to banning them entirely. The investigators research could help to integrate the regulation of this device in Hungary and in the EU as well. The measurement of acute oral effects of e-cigarette and a hungarian epidemiological survey would be novel in this topic.
This study aims to pilot a method of collecting the post-discharge follow-up data required by the Joint Commission Tobacco Measure Set, using text messages sent to and received from patients' cellular-telephones. It also aims to assess whether specially designed relapse prevention text messages designed to encourage abstinence from smoking, can increase the proportion of smokers who remain abstinent during the first month after discharge from hospital.
This study will examine the effects of combining Varenicline (VRN) and N-acetylcysteine (NAC) on neural circuitry function and treating nicotine addiction. Healthy adult nicotine dependent cigarette smokers interested in quitting (n=110) will be randomized to one of four PBO-controlled conditions for 4 weeks: 1) VRN+NAC, 2) VRN+PBO, 3) NAC+PBO or 4) PBO+PBO. Following 1 week of medication, participants will be contingently reinforced for 3 days of smoking abstinence and be scanned using functional magnetic resonance imaging (fMRI) techniques, while nicotine deprived during a resting state and a cue-reactivity (CR) task. Participants will be followed over the next 3 weeks of treatment and clinical variables will be assessed.
This study is evaluating the feasibility and short term smoking cessation outcomes of an automated smoking cessation intervention delivered via mobile phone text messaging as an adjunct to Varenicline in a primary care setting.
