The tobacco epidemic is a major public health threat, as more than eight million people around the world are killed in a year, according to the World Health Organization.

Since cigarette smoking is the most common form of tobacco use across the globe, we have put together top 10 facts about smoking, and their answers!

Q. Why is smoking addictive?

Smoking is addictive primarily because of nicotine, a chemical found in tobacco. Nicotine stimulates the release of neurotransmitters such as dopamine in the brain, which creates pleasurable sensations and reinforces the behaviour. Over time, the brain becomes dependent on nicotine to release dopamine, leading to cravings and withdrawal symptoms when nicotine levels drop. This cycle of pleasure and withdrawal makes quitting difficult, explains pulmonologist Dr Rohan Aurangabadwalla.

Q. I smoke just a few cigarettes. Will the health risks be lower compared to those who smoke more?

While smoking fewer cigarettes is less harmful than smoking many, there is no safe level of smoking. Even a few cigarettes a day significantly increase the risk of cardiovascular diseases, lung cancer, respiratory issues, and other health problems. The risks are dose-dependent, meaning they increase with the number of cigarettes smoked, but even light smoking carries serious health risks.

Q. How soon will I start seeing improvements in health after quitting smoking?

When you quit smoking, your body starts to recover almost immediately. Here’s a detailed timeline of the health improvements you can expect:

• Within 8 to 12 hours: The level of carbon monoxide in your blood decreases, allowing oxygen levels to increase to normal.
• Within 24 hours: The risk of heart attack begins to decrease as your body starts to cleanse itself of carbon monoxide and other toxins from cigarettes.
• Within 48 hours: Nerve endings start to regenerate, and your sense of smell and taste begin to improve.
• Within 72 hours: Your bronchial tubes start to relax and open up, making breathing easier. Your lung capacity begins to increase.
• Within 1 to 3 weeks: Blood circulation improves significantly, making physical activity easier and reducing the risk of blood clotting. Lung function can increase by up to 30 percent, says the expert.
• Within 1 to 9 months: Coughing, sinus congestion, fatigue, and shortness of breath decrease as the cilia in your lungs (tiny hair-like structures that help clean the lungs) start to recover. The overall function of your lungs improves, reducing the frequency and severity of respiratory infections.
• Within 5 years: The risk of stroke, and mouth, and throat cancers reduces.
• Within 10 years: The risk of dying from lung cancer is about half that of someone who continues to smoke, says the expert. The risk of cancer of the larynx (voice box) and pancreas decreases significantly.

Q. I have been smoking for long. Is it too late to stop?

Regardless of age or smoking history, quitting can significantly improve your health, so it is never too late. Former smokers experience reduced risks of heart disease, stroke, lung disease, and various cancers compared to those who continue to smoke, says Dr Aurangabadwalla. The sooner you quit, the greater the benefits, but even quitting later in life can extend and improve the quality of your life.

Q. Will I gain weight if I stop smoking?

Some people do gain weight after quitting smoking. It may vary between 5 to 10 pounds or 2-5 kgs. This happens because nicotine suppresses appetite and increases metabolism.

However, not everyone gains weight, and the health benefits of quitting far outweigh the risks associated with a modest weight gain. Eating healthy and exercising every day can help manage weight gain.

• Reduced coughing, sinus congestion, fatigue, and shortness of breath.
