The term 'Tobacco User' can be summarized as a SMOKER, which is a person who inhales and exhales the smoke of burning tobacco products. Smoking has been around for centuries, with evidence of its use dating back to 5000 BC. It is a popular form of recreational drug use, and is often used to relieve stress or boredom. Tobacco users are at risk of developing serious health problems, such as lung cancer, heart disease, and stroke.
