What is Smoking?
– Smoking involves inhaling tobacco smoke, which contains over 7,000 harmful chemicals, including nicotine, tar, and carbon monoxide.
– Nicotine is the addictive substance in cigarettes, making it hard for people to quit smoking even when they are aware of the risks.
– Smoking can damage nearly every organ in the body, leading to disease and reduced quality of life.
Symptoms of Smoking Addiction
– Frequent cravings for cigarettes, especially in situations like stress, after meals, or with coffee.
– Difficulty stopping smoking even when trying to quit.
– Irritability, anxiety, or difficulty concentrating when attempting to quit.
– Physical symptoms like coughing, shortness of breath, and frequent respiratory infections.
Causes and Risk Factors for Smoking
– Nicotine Addiction: Smoking is highly addictive due to nicotine, a chemical that stimulates the brain’s reward system.

Screening and Diagnostic Tests for Smoking-Related Conditions
– Lung Function Test (Spirometry): Measures how well your lungs work to detect conditions like COPD.
– Chest X-Ray or CT Scan: Detects lung damage or lung cancer caused by smoking.
– Carbon Monoxide Breath Test: Measures the amount of carbon monoxide in your breath, which increases with smoking.
– Blood Tests: Can measure the levels of nicotine or its byproducts, cotinine, to assess smoking levels.
– Cardiovascular Screening: Tests for high blood pressure, cholesterol levels, and heart disease due to smoking.

Treatment Options for Smoking Cessation
Behavioral Therapy
– Individual or group counseling helps people develop coping strategies to handle cravings and withdrawal symptoms.
– Cognitive-behavioral therapy (CBT) focuses on changing thoughts and behaviors associated with smoking.
Nicotine Replacement Therapy (NRT)
