The cells that produce mucus in your lungs increase when you smoke. As a result, the amount of mucus increases. But when you smoke, your lungs are not effective enough to clear the excess mucus. Therefore, the mucus remains in the airways, blocking them and causing constant coughing.
The extra mucus makes you susceptible to infection, and smoking interferes with the natural defense mechanisms that can protect you from infection.

When smoking tobacco, large amounts of nicotine enter the lungs and are quickly absorbed into the bloodstream. In fact, inhalation is the fastest way for a drug to reach the brain. Nicotine from a dirty cigarette reaches the brain just 7 seconds after inhalation.
Smokers have many more nicotinic receptors than non-smokers. When these receptors are filled with nicotine, they “fire” and cause the feelings you have when you smoke. When the receptors are low, you don’t feel well and the urge to smoke increases. When you stop smoking, many nicotinic receptors disappear, but the remaining ones have “memory” and can be activated by signals.
When you smoke, large amounts of nicotine are quickly released from your lungs into the bloodstream. The heart then immediately pumps it to your brain and the rest of your body. The reason smoking is so addictive is because of the high concentration of nicotine that is released so quickly.
