Filter by:This clinical trial explores the manipulation of e-cigarette (EC) nicotine to promote public health. Researchers are trying to understand and gather information about how the strength, form, and structure of nicotine in products play a significant role in their potential for addiction and how they might affect health risks. The information gained from this study may allow researchers to understand how these aspects of nicotine influence the potential for addiction, how people puff on ECs, how the body processes nicotine, and any potential harmful effects it might have on health. Exploring these specific characteristics of nicotine may also determine if an EC product standard could help identify optimal nicotine levels for users.
This clinical trial evaluates the characteristics of oral nicotine pouches (ONPs) to determine if they are a comparable substitute to cigarette or smokeless tobacco (ST) products. ONPs contain nicotine but no tobacco and are used primarily by adult tobacco uses in the United States (US). ONPs are recognized by the Food and Drug Administration as having lower risk than combustible cigarettes and are approved as a modified risk tobacco product. While ONPs have lower toxic risk than other tobacco products, acute and longer term harm related to their use has not been studied. Information gathered from this study may identify product characteristics of ONPs that improve successful switching from high-risk cigarettes or ST to lower risk ONPs.
This clinical trial tests the effects of tobacco cut and nicotine form on the abuse liability in participants who use moist snuff (smokeless tobacco [SLT]). Two features of moist snuff that are key targets of manipulation from the tobacco industry and drivers of its addiction potential are length of tobacco cut (long versus fine) and nicotine form (low versus high levels of nicotine in the free-base form). Finer tobacco cuts and higher levels of free-base nicotine (FBN) result in faster, greater nicotine delivery. Researchers want to gain information on how certain characteristics of moist snuff affect how long people use it, how it delivers nicotine, or how much people like it. This clinical trial may provide justifications for local, state, or federal regulations aimed at reducing the appeal and addictiveness of moist snuff.
This trial refines and evaluates how cultural targeting influences the effectiveness of anti-tobacco messages among lesbian, gay, bisexual, and transgender (LGBT) young adults at risk for the use of more than one tobacco product (polytobacco use). Polytobacco use is associated with nicotine dependence and tobacco use into adulthood, and is disproportionately high among LGBT young adults. This trial seeks to determine how cultural targeting can be applied to communicate polytobacco use risk to at-risk LGBT young adults.
This clinical trial tests the effect of tobacco flavor and liquid composition on the way a person puffs on a vape (topography). In general, tobacco products are designed with sensory factors in mind, such as flavor, to increase the appeal. Flavors and the composition of nicotine, either made in a lab (synthetic) or from tobacco, may create positive sensory effects, such as look, feel and taste, and influence smoking behavior and willingness to try different types of cigarettes. Understanding how nicotine vaping products are used is important in assessing individual and population level health risks. Vape flavors and synthetic nicotine may be related to harmful effects on health from vaping and may impact the appeal, risk beliefs and vaping topography.
This clinical trial examines the impact of nicotine patches on preventing cancer in rural and Appalachia Ohio residents. Nicotine pouches are new smokeless tobacco products that are marketed as substitutes for smokeless tobacco and are gaining in popularity. There is little research on how nicotine pouches will be adopted by residents of Ohio Appalachia and rural Ohio. This study may help researchers better understand the appeal and potential impact of nicotine pouches on public health.
This clinical trial tests how well providing education improves screening for lung cancer in patients with a history of smoking. Screenings may help doctors find lung cancer sooner when it may be easier to treat. Education and counseling may be an effective method to help providers and patients learn about lung cancer screening. Providing education and decision counseling to providers and patients may increase lung cancer screening.
This clinical trial evaluates how the content of waterpipe (WP) tobacco affects the appeal, puffing behavior, and toxicity of WP tobacco smoking. The data from the proposed study will provide direct links between WP tobacco's primary additives (sugars and humectants), CO and nicotine biomarkers, smoker preferences, perceptions of harm and puffing behaviors, and the subsequent range of toxicant exposures associated with these additives and behaviors. Study outcomes include waterpipe puffing behaviors, exhaled carbon monoxide levels, nicotine uptake, spirometry, sensory perceptions, smoking appeal, and risk perception. Waterpipe tobacco smoking is often the first combustible tobacco product tried by adolescents and young adults, possibly due to the widespread availability of heavily sweetened waterpipe tobacco and the perception that waterpipe smoking is a safer alternative to cigarette smoking. However, waterpipe tobacco smoking is associated with lung disease, carbon monoxide poisoning, and precursor conditions for oral and other cancers in adolescents and young adults. There is currently little data available on how the primary additives (by weight) in waterpipe tobacco affect puffing behaviors, toxicant exposures, pulmonary function and appeal. This clinical trial uses established waterpipe tobacco smokers, four investigational tobacco products with precisely manipulated levels of humectants and natural sugars in a single-blind, crossover (repeated measures) study design to determine how waterpipe tobacco additives effect human puffing behavior, nicotine uptake, flavor perceptions, lung function, and biomarkers of exposure.
This phase II trial tests whether oral iloprost works in preventing lung cancer (chemoprevention) in former smokers. Oral iloprost has previously been shown to reduce abnormal lung cells in former smokers, suggesting a clinically significant impact on lung cancer risk. The use of oral iloprost may help keep cancer from forming and reduce abnormal cells in the lung in order to lower the risk of developing lung cancer in former smokers.
This trial refines and evaluates anti-tobacco messages among lesbian, gay, bisexual, and transgender (LGBT) young adults at risk for the use of more than one tobacco product (polytobacco use). Polytobacco use is associated with nicotine dependence and tobacco use into adulthood, and is disproportionately high among LGBT young adults. This trial seeks to determine effective communication of polytobacco use risk to at-risk LGBT young adults.
