Smoking is a habit that has been present for centuries. It has been associated with social status, relaxation and coolness. However, the drawbacks of smoking are widely known as it poses a wide range of health issues. According to the World Health Organization (WHO), smoking kills more than 8 million people annually worldwide, making it the leading cause of preventable deaths. It is responsible for lung cancer, chronic respiratory diseases, and cardiovascular disorders.
Smoking causes lung cancer, which happens after carcinogenic substances in tobacco smoke damage the DNA in the lung tissue. The cancer cells then duplicate and generate a tumor. Symptoms of lung cancer include a persistent cough, shortness of breath, and unexplainable weight loss. Early diagnosis can increase the chance of successful treatment.
Smokers are at a higher risk of chronic respiratory diseases like chronic obstructive pulmonary disease (COPD), emphysema, and chronic bronchitis. These diseases impact the lungs’ function, breathing, and gas exchange ability. Individuals with these conditions often struggle with coughing, wheezing, constant fatigue, and recurring respiratory infections.
Moreover, smoking damage the cardiovascular system leading to heart attacks and stroke. Nicotine increases blood pressure and narrows the arteries, leading to a decreased oxygen supply to the heart and brain. This strain increases the likelihood of a heart attack or stroke.
In conclusion, smoking is a debilitating habit that leads to numerous health issues. Although it is challenging to overcome the addiction to smoking, it is possible with a combination of willpower and various nicotine replacement therapies, such as gums and patches. Smoking cessation will not only improve personal health but also lead to a better quality of life and prevent the spread of secondhand smoke. The slogan for the WHO campaign against smoking says it best, “Quit smoking, save lives.” So, let’s break the habit before the habit breaks us.
