Filter by:This prospective study assesses the pulmonary and cardiovascular effets of vaping in adult electronic cigarette users with biannual visits and a 5-year follow-up.
To evaluate the level of proinflammatory cytokines in individual vaping electronic cigarette in gingivitis patients. Can vaping affects the proinflammatory cytokines level in diseased individuals? Group I: cigarette smoker with gingivitis. Group II: electronic cigarette smoker with gingivitis. Group III: non-smoker with gingivitis. participants will be asked to perform oral hygiene instructions. measurement of inflammatory biomarkers MMP8 and MMP9 base line and after intervention will be done.
The goal of this clinical trial is to test the effects of social media use on e-cigarette use in young adults who use e-cigarettes. The main questions it aims to answer are: - Does reducing social media use change young adults' e-cigarette use? - Does reducing social media use change things such as young adults' mental health and what they see on social media? Participants will complete surveys and submit screenshots showing how much time they spend on social media. Researchers will compare young adults who reduce their social media use to young adults who use social media as usual, to see if their e-cigarette use differs.
Many people smoke cigarettes and use e-cigarettes, and have a hard time stopping. Nicotine replacement therapy medications, such as nicotine patches and lozenges, have been shown to help people quit e-cigarette use. The purpose of the present study is to see how well nicotine patches and lozenges help people quit both smoking and vaping, and to determine if higher doses of the medication work best.
Smoking is prevalent in Pakistan, and a large proportion of the adult population smokes cigarettes or uses other forms of tobacco. Smoking cessation programmes are not well established, and the few centres that offer cessation, only provide basic support without stop-smoking medicines or other aids that can help people quit. Internationally approved stop-smoking treatments like nicotine replacement therapy (NRT) are available in larger cities, but they are very expensive. This makes it difficult for the general population to use NRT to aid in their desire to quit smoking. In the past few years, the use of electronic cigarettes (EC) has increased manifold. These devices are freely available and are offered in a wide variety of types and flavours. EC are also cheaper compared to NRT, which makes them affordable for most smokers. EC are not considered smoking cessation tools and are not used or recommended by cessation services. This study wants to compare EC with NRT to see which treatment is more successful in helping people quit smoking. The premise is that EC are more effective than NRT. The study also wants to determine the cost of using EC compared to that of NRT, when used for quitting smoking. The study will have a total of 438 participants who will be assigned randomly (by chance) to two groups: NRT and EC. 219 participants will be provided with NRT, and 219 with EC. The participants will be adult smokers presenting at designated smoking cessation centres who are seeking help in quitting smoking. The main focus of the study is to see if EC are more successful than NRT in helping people quit smoking at the end of one year. This research will provide useful information on the effectiveness and safety of EC and help develop a smoking cessation policy tailored to the population of Pakistan.
The purpose of this study is to determine if abuse liability indices will be impacted by varying flavors and e-cigarette (ECIG) nicotine delivery capability (i.e., nicotine flux) among current combustible cigarette users. The investigators will compare abuse liability indices between three FDA-authorized ECIG products that vary in nicotine flux (but are all tobacco flavor) and own brand cigarettes. The investigators will also test the influence of ECIG flavor availability (tobacco vs. menthol) within three ECIG product classes.
This study assess the ways in which e-cigarette product characteristics, such as flavors and nicotine salts, impact user experience to inform potential regulations.
This study assess the ways in which e-cigarette product characteristics, such as marketing strategies, impact user experience to inform potential regulations.
This project will assess the ways in which e-cigarette product diversity impacts the user experience to inform potential regulations by identifying product characteristics that may: (1) put young adults at risk for tobacco product use; and (2) facilitate adult smokers switching to e-cigarettes. There are three primary objectives to the study: (1) Determine which dimensions of e-cigarette product diversity differentially affect product appeal in the overall population of tobacco product users as well as affect product appeal across young adult e-cigarette users and middle-age/older adult smokers; (2) Determine which dimensions of e-cigarette product diversity differentially affect product appeal in the overall population of tobacco product users as well as affect abuse liability in young adult e-cigarette users and the ability to resist smoking in adult smokers; (3) Determine the affect of product characteristics on e-cigarette nicotine delivery profile. For this substudy, adult smokers (N=200) will attend two laboratory session in which they will self-administer e-cigarette products varied according to within-subject e-cigarette factors (e.g., flavor, nicotine formulation) and smoke their own cigarettes.
The goal of this study is to conduct a pilot randomized waitlist-controlled trial to assess the feasibility, acceptability, and preliminary effects of substituting the NIDA standardized research e-cigarette (SREC) for combusted cigarettes in MOUD-TUD who are not ready to quit smoking. A waitlist controlled RCT using a mixed-methods sequential explanatory design will investigate the impact of SREC provision on: 1) tobacco use behavior (e.g., cigarettes per day [primary outcome], SREC use), 2) biomarkers (e.g., carbon monoxide, anabasine), 3) cigarette dependence and withdrawal, and 4) short-term health effects and tolerability (e.g., respiratory symptoms, substance use). In the proposed RCT, N=40 adults stable on MOUD with buprenorphine who report daily smoking recruited from MGH primary care practices will be randomly assigned to receive the SREC for 8 weeks, either immediately (iSREC), or after an 8-week delay (waitlist control [WLC]). They will be followed an additional 4 weeks after SREC provision ends (to 12 weeks in iSREC and 20 weeks in WLC).
