Tobacco is the most preventable cause of disease and death in Canada. Although the tobacco use rate has substantially gone down in the general population, significant differences exist between sub-populations in Canada, for example Ottawa's highly vulnerable homeless or at-risk for homelessness population has an almost 100% tobacco smoking rate relative to 9-18% in the rest of the Canadian general population. This stark inequity in tobacco use translates into devastating healthcare outcomes such as a disproportionate amount of cancer, stroke, heart disease and death. Canadians who are homeless or at-risk for homelessness die 25 years earlier than housed Canadians, mostly due to tobacco. In order to tackle this tobacco use related inequity - a novel approach is urgently needed. Despite commonly held dogma that People Who Use Drugs (PWUD) don't want to quit smoking, many studies have demonstrated that in fact they are very interested in quitting. Moreover, the investigators pragmatic peer-led community-based action approach used in their PROMPT project has demonstrated that tobacco dependence strategies can be implemented with great success in this population. The majority of PROMPT participants reduced or quit tobacco use, in addition to reducing or quitting all other drug use. Importantly, the investigators have demonstrated that it is possible to gain the trust and engagement of marginalized populations and that researchers can create a community space that is low-threshold, safe and non-judgmental. The investigators aim to compare two tobacco dependence management strategies in the homeless (or at-risk for homelessness) multi-drug use population in Ottawa and Toronto. They will use the same peer-led approach in PROMPT with community peer researchers with lived experience; with the hope that the cost-effective community based framework derived from this trial will serve as a template for interventions and treatments in community settings for chronic diseases such as obesity and diabetes.
Background: Smoking is a major public health problem in the U.S. Almost a half a million Americans die from it in a year. One thing that contributes to why people smoke is the marketing of cigarettes. Cigarette direct mail marketing usually targets young smokers of lower socioeconomic status. Researchers want to find out more about how this kind of marketing influences smoking behavior in young people from different socioeconomic levels. Objectives: To study the effects of cigarette direct mail marketing on beliefs, responses, and arousal. To study how these things may differ among young adult smokers of high and low socioeconomic status. Eligibility: Volunteer adults ages 18 to 29 who smoke. Design: Participants will have 1 visit. Participants will be asked questions about their health and recent smoking. A nurse will check their vital signs. Participants will have a simple eye exam. They will give blood and urine samples. Participants will be connected to equipment. This will collect data while they look at pictures. Then they will have a 10-minute break. A nurse will observe them during the break. Participants will have their breath analyzed. Participants will answer questions. The topics will include: Education Job Income Family history Tobacco use Exposure to pro-smoking and anti-smoking messages History of drug and alcohol use
Background: . Bipolar disorders and tobacco use disorder are top of the causes of disability and mortality worldwide Objective: The aim of this study was to evaluate N-acetyl-cysteine (NAC) as an adjunctive treatment in patients with bipolar .disorders and tobacco use disorder (TUD) , to determine whether NAC reduces alterations in biomarkers of inflammatory and oxidative stress Methods: This study will be conducted as a double-blind, randomized, placebo controlles add NAC or placebo for .bipolar disorders and tobacco use disorder at Londrina State University, Brazil.
RATIONALE: Diagnostic procedures, such as an urgent chest x-ray, may help in planning cancer treatment. It is not yet known whether standard medical care is more effective than an urgent x-ray in diagnosing lung cancer in smokers with chest symptoms who are older than 60 years. PURPOSE: This randomized clinical trial is studying standard medical care to see how well it works compared with an urgent chest x-ray in diagnosing lung cancer in smokers with chest symptoms who are older than 60 years.
This research project addresses the hypothesis that a neurocognitive profile characterized by impairment of response inhibition and sustained attention may be a risk factor for smoking initiation and nicotine dependence among young women. Nicotine has short- term, facilitating effects on attention and response inhibition. Therefore, individuals who are impaired on cognitive functions such as these and initiate cigarette smoking may be more likely to maintain the habit and develop nicotine dependence. The research protocol specifically tests whether administration of nicotine to non-abstinent, regular cigarette smokers improves cognitive function in those domains where the participants had previously been shown to manifest performance deficits
