Smoking: Health Risks, Quitting Help, and Related Medications

When you smoke, you’re not just inhaling tobacco—you’re exposing your body to over 7,000 chemicals, many of them toxic or cancer-causing. Smoking, the act of inhaling and exhaling the smoke from burning tobacco, often through cigarettes, cigars, or pipes. Also known as tobacco use, it’s the leading preventable cause of death worldwide. It doesn’t just hurt your lungs—it tightens blood vessels, raises blood pressure, and weakens your immune system. Every puff increases your risk of heart disease, stroke, COPD, and at least 12 types of cancer. And it’s not just the smoker: secondhand smoke kills nearly 1.3 million people a year globally, according to the World Health Organization.

Quitting isn’t easy, but it’s the single best thing you can do for your health. Within 20 minutes of your last cigarette, your heart rate drops. After 12 hours, carbon monoxide levels in your blood return to normal. After one year, your risk of heart disease cuts in half. But cravings and withdrawal—headaches, irritability, trouble sleeping—are real. That’s why nicotine addiction, a physical and psychological dependence on nicotine, the main addictive substance in tobacco needs more than willpower. smoking cessation, the process of stopping tobacco use, often supported by medication, counseling, or behavioral therapy works best when you have the right tools. Medications like nicotine patches, gum, or prescription pills such as varenicline (Chantix) and bupropion (Zyban) help reduce cravings and withdrawal symptoms. Many people also benefit from combining these with support groups or counseling.

Smoking doesn’t just affect your lungs—it impacts your whole body. People with arthritis, heart conditions, or chronic pain often find their symptoms get worse because smoking reduces blood flow and slows healing. That’s why doctors often recommend quitting before starting certain treatments, like surgery or long-term pain management with NSAIDs like diclofenac.
