How Nicotine in Cigarette works

Cigarette smoking is very much prevalent all over the world. Smoker not only spoils himself but also pollutes the environment. Now what is the content which makes a cigarette? The main ingredient is Nicotine (C10H14N2), which is a naturally occurring liquid alkaloid. A cigarette contains 8 to 20 mg of nicotine depending on the brand. 1 mg of nicotine is absorbed when a person smokes one cigarette.


How nicotine affects the human body?

Step 1: A person smokes cigarette

Step 2: Nicotine moves to the small blood vessels that line the skin, lungs and mucous membrane

Step 3: Then it travels via the blood stream and reaches brain

Step 4: It is delivered to the rest of the body


How does the brain reacts with nicotine?

When nicotine is inhaled it first travels to the lungs. The alveoli in the lungs provide ample access for nicotine and travels via the blood to reach brain. Once it reaches the brain it creates a good feeling which is experienced by smokers. It also causes irritability when the person quits. Thus the person becomes an addict to cigarette.


Effects of nicotine on the liver

Liver produces an enzyme for breaking down of nicotine so that it can be excreted in the urine. When a person smokes more the enzyme is produced to that extent due to over activity there is inflammation in and this may lead to cancer.


Other major effects

1. Nicotine increases the basal metabolic rate of an individual. So he/she burns more calories and thus reduces the weight of an individual.

2. Nicotine increases the level of LDL (low density lipoprotein) which is also called as bad cholesterol. Thus it damages the arteries lining the heart and may lead to stroke.

3. Nicotine releases adrenaline and this leads to rapid heart beat and increased blood pressure.

4. Nicotine blocks the release of insulin and this may lead to a condition called as hyperglycemia.

5. Nicotine damages the entire lungs and this may lead to lung cancer.
