Smoking is more than a habit for many smokers. It's a nicotine addiction.
When you smoke, nicotine reaches the brain in about 10 to 20 seconds. This causes a chemical called dopamine to be released in the brain. Dopamine provides a feeling of pleasure.
Over time, smoking may become more than just a habit. It can become an addiction. And as with most addictions, when you take away the thing that you're addicted to, you may experience physical withdrawal symptoms. When you quit smoking, it's no different. You take away the nicotine, and that may cause your body to go through nicotine withdrawal symptoms.
