--> This is a substudy of the main ESTxENDS trial (NCT03589989). Olfactory function outcomes should be considered secondary outcomes of the main smoking cessation outcome formulated in NCT03589989. Up to one in five people have suffered loss or impairment of their sense of smell, limiting their available information about the environment, including possible hazards (e.g. gas or smoke). An impaired sense of smell is strongly associated with smoking, but its prevalence in smokers has yet to be established. Since only a few prospective cohort studies among smokers have compared change in olfactory function in smokers, it is not known how much or how fast smoking may impair olfactory function. Some studies describe improvement in olfactory function among quitters, supporting anecdotal evidence from ex-smokers who say they regained their sense of smell over time. As far as the investigators know, no randomized controlled trial has tested the effects of a smoking cessation intervention on olfactory function. A reliable and validated olfactory function test is the Burghart Sniffin' Sticks 16-item Identification-test, which is quick and easy to administer. 16 familiar odours will be presented to the participants, each for 3-4 seconds. After each odour the participant is asked to select the correct answer from 4 possible answers. With increasing popularity of e-cigarettes, their effect on the olfactory function also needs to be assessed. It is known, that e-cigarettes produce toxic compounds such as carbonyl and aldehydes, what could impair the sense of smell - especially if the liquid-level is too low or the temperature on the coil is too hot. This is the source of a phenomenon called "dry-hit", which is said to leave a burnt taste or smell to be recognized by users. However, it is unclear if e-cigarettes users with an olfactory dysfunction can adequately recognize a "dry-hit". Therefore, the goal is to investigate the effects of smoking cessation and use of ENDS on olfactory function and the recognition of a "dry-hit" from a test e-cigarette. For the main ESTxENDS trial (NCT03589989), cigarette smokers motivated to quit smoking cigarettes will be included. Participants in the intervention group will receive an ENDS and nicotine-containing e-liquids, which they will be allowed to use ad libitum. Additionally, they will receive smoking cessation counseling. Participants in the control group will receive smoking cessation counseling only. All participants will be followed over a 24-month period. The primary objective is to assess changes in olfactory function from baseline to 6 months post target quit date (TQD) in cigarette smokers randomized to the intervention group compared to the control group.
The study team will conduct a feasibility, acceptability, and preliminary efficacy trial comparing Learn to Quit-HIV (n=30) to an app based on U.S. Clinical Practice Guidelines only (NCI QuitGuide; n=30) among HIV-positive smokers. Both apps will be integrated with NRT and ongoing HIV clinical care.
The objectives are: i. To evaluate Smoke-free Teens' change in knowledge on smoking hazards, attitudes towards smoking, tobacco control and smoking cessation, and practices for promoting smoking prevention and cessation, ii. To evaluate the process and quality of smoke-free programmes organized by the Smoke-free Teens in their schools/community, and iii. To measure the number of people reached in the smoke-free programmes organized by the Smoke-free Teens.
Tobacco control is a Public Health priority. Tobacco is directly responsible for 75,000 deaths per year in France. Without help, less than 5% of smokers are still abstinent within 12 months of quitting. The use of nicotine substitutes only increases the chances of success in smoking cessation by 2 to 3%. Brain imaging research shows that the dorsolateral prefrontal cortex (DLPFC) is involved in tobacco addiction. Disorders induced in the CPFDL cause an irrepressible desire to smoke (craving) and explain a large part of the relapse at the time of smoking cessation. Transcranial magnetic stimulation (TMS) could be promising in smoking cessation. This technique allows direct stimulation of the DLPFC via a magnetic coil, so as to reduce the cortical activity of the DLPFC, and thus reduce tobacco craving. A first randomized controlled study was conducted at the Dijon University Hospital in Dijon in smokers who were heavily addicted and who had failed with the usual withdrawal strategies. In this study, it was found that the combination of nicotine substitutes (to reduce the physical symptoms of withdrawal) with 10 sessions of TCS (to reduce craving) made it possible to maintain abstinence from tobacco during the first 2 weeks of withdrawal (% abstinence = 88.8% active TCS group vs. 50% placebo TCS group; p=0.027). However, in this study, the therapeutic effect of the nicotine-TCS combination was not prolonged once the stimuli stopped. At 6 and 12 weeks from the start of withdrawal, abstinence rates in the active SMT and placebo SMT groups were no longer significantly different. It is therefore proposed to renew the protocol by adding maintenance brain stimulation to the initial protocol. Used in the treatment of depression, the maintenance brain stimuli could increase the chances of smoking cessation.
This placebo-controlled Phase 3 study is being conducted at sites within the United States to evaluate 3 mg cytisinicline TID for treatment duration of 42 days/6 weeks as well as repeating that duration for a total of 84 days/12 weeks treatment.
The current pilot study will assess the feasibility and acceptability of a novel mHealth app designed for people who are ambivalent about quitting smoking. Results will be used to refine the intervention and plan for a future randomized effectiveness trial.
The Quit and Stay Quit Monday model is an innovative smoking cessation approach that guides smokers' behavior without requiring additional resources. The investigator will conduct a randomized control trial evaluating the effectiveness of this model as compared to usual smoking cessation care in a population of smokers with a mental health condition.
The investigators tested the feasibility of a culturally and linguistically sensitive smoking cessation program with combined counseling and pharmacological components for Chinese smokers in New York City; identified factors and techniques that enhance the administration and appropriateness of the intervention program; and examined the effectiveness of this program on quit attempts, quit rates, and overall smoking reduction.
To establish a dose-effect curve for nicotine's abuse potential as a function of nicotine dose and delivery rate. Pulsed IV nicotine administration will be used as it closely matches nicotine delivery by inhaled tobacco use.
