Filter by:Waterpipe (WP) smoking has become one of the leading tobacco use methods among youth in Florida. The impact of this dramatic rise is amplified by the mounting evidence of WP addictive and harmful nature, as well as the lag of policy response to it. Evidence suggests WP use leads to nicotine addiction, and increases the risk of lung cancer, heart and respiratory disease and exposure to secondhand smoke. The spread of WP use among youth has been fueled by a misperception of reduced-harm compared to cigarettes. Health Warning Labels (HWLs) represent one of the most successful tobacco control strategies to communicate smoking- related risks, and studies have consistently shown that HWLs are associated with a decrease in smoking rates and smoking-related morbidity and mortality. Therefore, communicating WP risks to young people through HWLs has been identified as a priority by major health bodies in the US including the FDA. Using the Delphi method among international tobacco control experts, our team has developed a set of 12 WP HWLs corresponding to 4 health themes; health risks/addiction, harm to others, WP-specific harm, WP harm compared to cigarettes. Building on this work, and using a mixed- method approach incorporating qualitative and quantitative research, the investigators propose to: Aim 1: Adapt the 12 HWLs to young WP smokers in Florida using exploratory focus groups. Aim 2: Test in a clinical lab experiment the performance of the top 4 HWLs on the WP device compared to no-HWL/control on harm perception, intention to quit, and toxicant exposure (Carbon monoxide (CO), nicotine, oxidative stress). Aim 3: Use the knowledge obtained to advocate for the adoption of WP-HWLs policies and disseminate information about WP harmful effects to young people in Florida and nationally. Communicating WP risks through HWLs promises to reduce WP use and WP-related morbidly and mortality among young adults in Florida. This pioneering work will inform the FDA and public health advocates on the potential of WP-HWLs policies and provide a model for other states to respond to the WP epidemic.
The main objective of the study is to assess the effect of waterpipe smoking on periodontal health, which will be done using a well constructed validated questionnaire. Then a full periodontal examination and x-ray evaluation will be done for all of the participants.
Title: Acute effects of waterpipe smoking (WPS) on cognitive measures and cardiorespiratory parameters Objectives: To evaluate the acute effect of one cession of water pipe smoking on: 1. executive functions which evaluated by cognitive tests administered included the digit span subtest Wechsler Adult Intelligence Scale (WAIS)-version III hebrew battery, and the Paced Auditory Serial Addition Test (PASAT) 2. Cardiorespiratory parameters included vital signs, spirometry parameters and lung clearance index (LCI) value 3. serum carboxyhemoglobin, nicotine, and cytokines Design: Prospective study evaluating these parameters before and after 30 minutes of water pipe smoking (WPS). Sample size: 55 participants (35 study group, 20 control group) Participant selection: Adults subjects who regularly smoke water pipe. Intervention: Each subject will undergo evaluation including cognitive tests, Cardiorespiratory parameters, carboxy- hemoglobin levels, nicotine levels, serum cytokines levels. All measurements will be evaluated before and after one cession of 30 minutes water pipe smoking
This project addresses the need for evidence about the effect of flavoring manipulation on waterpipe smokers' satisfaction, dependence, harm perception, and toxicants exposure. Specifically, in this clinical study investigators will compare the effect on flavored and non-flavored waterpipe tobacco on smoking behavior, subjective experiences and toxicant exposure among waterpipe users. Findings from this study will help informing flavor-based product regulation by the FDA.
Waterpipe smoking is a tobacco use method in which smoke passes through a partially-filled water jar. Burning charcoal heats the waterpipe tobacco which produces the smoke that the user inhales. Waterpipe smoking was associated with increased risk for coronary heart and pulmonary diseases. This Waterpipe Study will inform the FDA on regulating waterpipe tobacco products and reduce the harm of it use. This study will be conducted at homes of hookah smokers, in natural settings, aimed to determine the effects of waterpipe smoking practices on physiological injury markers and biomarkers of toxicity of waterpipe tobacco smoking. The investigators will employ a repeated measures design. The investigators will recruit a sample of 50 adult male and female exclusive waterpipe smokers and a control sample of 25 male and female non-smokers via intercept interviews from San Diego County, California communities. Waterpipe smokers will smoke one waterpipe tobacco head (10g) of Starbuzz during 3 separate sessions with a 7-day washout period before each session, as follows: Session 1, Smoking waterpipe tobacco using 1 quick-light charcoal and room temperature water in the waterpipe jar, Session 2, Smoking waterpipe tobacco using 1 quick-light charcoal and adding ice cubes to the water in the waterpipe jar, and Session 3, Smoking waterpipe tobacco without charcoal using a charcoal-free electrically heated waterpipe head to heat the tobacco, and room temperature water in the waterpipe jar. The following data will be collected: a) Tobacco Use History, b) 4-week Tobacco Exposure Diary, c) Waterpipe Use Session Form, d) Carbon monoxide (CO) exposure: Micro+ Smokerlyzer® CO monitor will be used for exhaled CO pre and 2 minutes post each smoking session, e) Pulmonary function testing and measuring blood pressure, heart rate and respiratory rate, and f) 6 first morning urine samples: pre and post the 3 sessions to measure urinary cotinine, a metabolite of nicotine, 4-(methylnitrosamino)-1- (3-pyridyl)-1-butanol (NNAL) and NNAL-glucuronides (total NNAL), metabolites of the lung carcinogen 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone (NNK), 1-hydroxypyrene (1-HOP), a metabolite of the genotoxic carcinogen pyrene, and S-phenylmercapturic acid (SPMA), a metabolite of the human hematotoxicant and leukemogen benzene. The investigators will explore exposure levels to furan, a liver toxicant and carcinogen, among waterpipe smokers via measuring its urinary metabolite Furan-BDA-NAL.
The overall aim of the current study is to determine if flavorings contribute to the initiation and maintenance of waterpipe (WP) smoking and also influence how a WP is smoked, which has implications for both risk of dependence but also smokers' level of exposure to tobacco-related toxicants. A total of 94 current WP smokers (47 low dependent, 47 high dependent) will be recruited. Based on our team's previous studies we conservatively assume a 20% attrition rate; thus, we will need to recruit 94 participants to have 76 complete all four sessions. Consistent with other laboratory studies of waterpipe smoking, participants who meet the following eligibility criteria will be asked to take part in the study.
Waterpipe is a tool for smoking tobacco, which is thought to be less harmful than cigarette. Unfortunately, there aren't adequate studies about its harms to health that are threatening the young generation all over the world today. The objective of this study was to show the carbon monoxide (CO) levels in waterpipe smokers' breaths, whether can be used or not to reflect the changes of oxidative stress for this reason to predict harmful effects on the pulmonary functions.
Tobacco use kills more than 500,000 people in the United States each year. Although the use of cigarettes has declined, the use of other tobacco products has remained steady. Waterpipe smoking is a common form of tobacco smoking after cigarettes in the U.S. In fact, in 2007 the American Lung Association issued a policy alert to warn consumers about this first new tobacco trend of the 21st century (American Lung Association, 2007). Few studies have been conducted on waterpipe smoking to investigate its harmful effects. Furthermore, no known studies have evaluated treatments for smoking cessation in waterpipe smokers. This study aims to test the role of contingency management (CM) in promoting abstinence from waterpipe smoking for 5 weeks verified by salivary cotinine and to characterize self-reported nicotine withdrawal symptoms. Based on the alarming growth rate over a short period of time in waterpipe tobacco smoking, there is a critical need for clinical research to investigate treatment modalities targeting smoking cessation for waterpipe smokers. Given the evidence for the role of CM in promoting abstinence from many types of drug use, investigation of the utility of CM for waterpipe smoking cessation is important and timely. Although Nicotine Replacement Therapy is the mainstay treatment for treating nicotine dependence delivered through cigarettes, the intermittent use patterns that characterize waterpipe smoking suggest that CM may be more effective in promoting waterpipe smoking cessation. The evidence based knowledge generated in this study may assist in the translation of the treatment program into public health practice.
