In Australia, as in many other countries, smoking tobacco is often considered the single most important preventable cause of chronic illness and preventable death. Smoking is a major risk factor for various chronic diseases, including heart disease, lung cancer, chronic obstructive pulmonary disease (COPD), and many others. Therefore, efforts to reduce smoking rates and promote smoking cessation are critical for improving public health and preventing chronic illnesses and premature deaths. Hope this helps you have a good day
