In the 20th century, tobacco caused the death of 100 million people worldwide and it is estimated that it will be responsible for 1 billion deaths in the 21st century. Currently 8 million people die each year from smoking, 7 million are associated with active smoking, thus being the main risk factor for loss of disability-adjusted life years for men and the ninth most important risk factor for women. In previous studies it has been reported that approximately 21% (14%-30%) of subjects who have required hospitalization are active smokers, being higher in men than in women (28% vs 14%). The initiation of treatment for smoking cessation in this group of subjects has shown an effectiveness rate of up to 65% to maintain abstinence 6 to 12 months after discharge. The effectiveness has been analyzed in scenarios with only brief advice, in some others with the use of medications such as varenicline, bupropion and nicotine replacement therapy, however, the interventions have not been standardized for adequate analysis, which could contribute to the different results.
The goal of this clinical trial is to determine the effectiveness of the combination of n-acetylcysteine and motivational enhancement therapy on laboratory improvement in the form of changes in blood nicotine, radiological changes in the form of nerve connectivity on post-therapy frontostriatal fMRI examination and clinical changes in the form of abstinence, withdrawal symptoms and cravings in adult smoker.
Tobacco use remains the foremost cause of preventable deaths in the U.S. and worldwide. Advancing new smoking cessation therapies, including those targeting novel biological mechanisms, is a critical public health priority. Accumulating evidence from preclinical studies suggests that glucagon-like peptide-1 (GLP-1) receptor agonists reduce intake and/or reinstatement of addictive drugs, including nicotine. However, translational work is necessary to establish whether GLP-1 receptor agonists alter aspects of nicotine response and smoking behavior in smokers. Human laboratory studies play a pivotal role in drug development by providing a time- and cost-efficient means of validating preclinical findings, also providing an ideal platform for studying mechanisms of medication effects. This is an experimental investigation to examine the effects of an approved GLP-1 receptor agonist on nicotine intake and reinstatement. Dependent smokers will be enrolled in a double-blind, parallel-arm trial with laboratory endpoints. Laboratory procedures will include a validated procedure for measuring smoking lapse/reinstatement after overnight abstinence. This study will provide initial laboratory evidence for the potential efficacy of GLP-1 receptor agonists as adjunctive treatments for smoking cessation.
The aim of the study is to evaluate the effectiveness of long-term and short-term app-based self-guided psychological interventions to reduce craving and lapse risk in problematic behaviors (compulsive sex, pornography, overeating, gaming, gambling) and substance use (cannabis, nicotine). Participants are randomly assigned to either the intervention group or the control. Participants in the intervention group have access to short-term and long-term interventions, whereas those in the control group only have access to the weekly ecological momentary assessment reports. Participants in the intervention group are able to access the intervention materials 5 days after enrollment and receive weekly ecological momentary assessment reports. Those in the control group will be granted access to all intervention materials after five weeks following study enrollment. A questionnaire battery assessments is administered (1) at baseline in the first week following onboarding in; (2) after 5 weeks; (3) after six months. In addition, longitudinal data on several variables related to craving and lapse risk are collected daily using ecological momentary assessment
Electronic nicotine delivery systems (ENDS) heat and vaporize a nicotine-containing liquid to produce an aerosol that can deliver nicotine to the blood and the brain. ENDS use has increased rapidly in the last decade, especially among youth: over 20% of US high school students are current ENDS users, and there is evidence of nicotine dependence in this population. Federal legislation has been proposed that would restrict ENDS liquid nicotine concentration to make ENDS "significantly less addictive and appealing to youth." However, these and other efforts to curb addiction by limiting nicotine liquid concentration are unlikely to succeed because nicotine emissions from ENDS depend on multiple variables. To achieve the intended public health aims, regulations targeting addiction must focus on nicotine delivery, not nicotine concentration. While nicotine delivery cannot be regulated directly, the rate at which an ENDS emits nicotine, the "nicotine flux", can be regulated and, importantly, predicted based on a few device design and operating variables. However, to date there is no empirical evidence demonstrating the relationship between flux and delivery, nor between flux and the subjective effects that support nicotine dependence. Closing this gap is essential for providing an effective framework for regulating ENDS. At the American University of Beirut, the investigators will assess the relationship between nicotine flux, form, and subjective effects. Participants will use ENDS devices with varying nicotine fluxes and forms. Dependency measures, such as urge to smoke, craving, and abstinence, will be assessed. The outcome will indicate the degree to which nicotine flux/form influence subjective effects related to dependency, puffing intensity, and exposure to toxicants. In summary, this project will provide the empirical evidence needed for public health agencies to use nicotine flux as an encompassing and convenient construct to regulate nicotine delivery from ENDS.
The purpose of the present study is to examine the pharmacokinetics and pharmacodynamics of "tobacco-free" oral nicotine pouches, at various doses and flavors, in healthy adult smokers. The study will utilize a within-subjects, double-blind design. Upon enrollment, participants will complete 7 dosing conditions: tobacco-flavored pouch (low or high nicotine dose), mint/menthol-flavored pouch (low or high nicotine dose), and fruit-flavored pouch (low or high nicotine dose); participants will also complete a condition where the participants will smoke participants' preferred brand of cigarettes. In each experimental session, participants will complete 2 product-use bouts. In bout 1, the participants will use a single product (pouch or cigarette) for a fixed period under controlled conditions. In bout 2, participants will be given 2 hours to use participants' assigned product ad libitum.
Patients with schizophrenia spectrum disorder (SSD) will be exposed to active repetitive transcranial magnetic stimulation (rTMS) from F8 coil or active rTMS from H coil for smoking cessation. Smoking and brain functional connectivity changes will be assessed at baseline, different stages of rTMS and/or follow-ups.
A pragmatic, single blinded, randomized, controlled non-inferiority trial of Cytisine versus Nicotine Replacement Therapy for continuous abstinence is conducted in the government run primary health hospitals in Mongolia.
