Tobacco use research is the study of the prevalence, patterns, health effects, and interventions related to the use of tobacco products, such as cigarettes, cigars, and smokeless tobacco. This area of research aims to understand the impact of tobacco use on individuals, populations, and society as a whole, and to develop strategies to prevent and reduce tobacco use and its associated health risks, including cancer, cardiovascular disease, and respiratory disease. This research is important for informing public health policies and interventions to promote smoking cessation and reduce the harm caused by tobacco use.
