What do you know about Nicotine?

Nicotine is the main addictive ingredient of tobacco, nicotine is both a sedative and a stimulant.

Cigarette smoke contains over 4000 different compounds 

When somebody smokes a cigarette his body is exposed to nicotine.

Nicotine rapidly absorbed by the lungs and enters the bloodstream, then rapidly delivered to the brain and reaches the brain within 8 to 20 seconds (70% of the tar remains in the lungs) the individual experiences a “chock." This is partly caused by nicotine stimulating the adrenal glands, which results in the release of adrenaline.

This surge of adrenaline stimulates the body. There is an immediate release of glucose, as well as an increase in heart rate, breathing activity, and blood pressure.

Nicotine also makes the pancreas produce less insulin, causing a slight increase in blood sugar or glucose.

Indirectly, nicotine causes the release of dopamine in the pleasure and motivation areas of the brain. A similar effect occurs when people take heroin or cocaine. Dopamine is a brain chemical that affects emotions, movements, and sensations of pleasure and pain. If your brain dopamine levels rise, the feeling of contentment is higher.

Nutt et Al’s  expert panels rated nicotine (tobacco) as the third most addictive substance after Heroin and Cocaine.

In 2002 the WHO estimated and there were more than 1 billion smokers and it has been estimated that tobacco will kill more than eight million people annually by 2030.
