All About Smoking Hazards
What happens when you smoke? Why is it difficult to give up smoking? During the process of smoking,a chemical compound called nicotine present in the smoke releases extra amounts of brain chemicals dopamine and norepinephrine which give you the sense of pleasure, fulfillment and satisfaction. These chemicals are produced naturally by your body through which you experience satisfaction from simple acts such as taking a cup of hot drink near the fire during extreme winter. But for a habitual smoker the body starts to depend on the nicotine to release the chemicals. Gradually the amount of nicotine requirement increases over a period of time.
