Harmful effects of smoking cigarettes

It is evident that cigarette smoking is a health hazard. The health burden of smoking is at its large due to well-established increases in the risk of serious chronic disorders, including coronary artery disease and stroke, chronic lung disease, and many cancers. Smoking can lead to a variety of ongoing complications in the body, as well as long-term severe effects on your body systems. Smoking can increase your risk of a variety of problems over several years; some of the bodily effects are immediate. Some of the harmful effects of smoking are the following:


Central nervous system:


Nicotine causes severe effects on the Central Nervous System and harms it severely. Nicotine reaches your brain in a few seconds and makes you feel more energized for a while. But as that effect wears off, you feel fatigued, tired, and crave more. Continuous physical withdrawal from nicotine can lessen your cognitive functioning and make you feel irritated and depressed. Withdrawal can also cause headaches and sleep problems. Cigarettes act as a central nervous system stimulant, affecting the neurotransmitters serotonin, dopamine, norepinephrine, acetylcholine, GABA, and others.


Cardiovascular Disease:


Several studies have suggested that cigarette smokers have a lower case fatality after myocardial infarction than non-smokers with a reduction in fatality of 40% or greater in some reports.

Tobacco and health explanations for this association have been advanced, including differences between smokers and non-smokers in the types of arterial lesions that precipitate infarction, the beneficial effects of the smoking cessation enforced by a hospital admission, and confounding by other prognostic factors.


The last possibility is almost certainly part of the effect that there are strong associations between smoking and substantial prognostic factors have been demonstrated. Smoking ranks among the top causes of cardiovascular disease, including coronary heart disease, ischemic stroke, peripheral artery disease. Smoking also raises blood pressure, weakens blood vessel walls, and increases blood clots. Together, this raises your risk of stroke.


Lung Cancer:


Smoking causes significant changes in your lungs and airways. Some chronic changes happen slowly and can last a lifetime like emphysema. When you smoke, the cells that produce mucus in your lungs and airways grow in size and number. As a result, the amount of mucus increases and thickens. Your lungs cannot effectively clean out this excess mucus. So, the mucus stays in your airways, and makes you cough. This extra mucus is also lead to infection. Smoking causes your lungs to age faster and hinders their natural defense mechanisms from protecting you against infection. Smoking inflames and irritates the lungs. Smoking also can destroy and harm your lungs and lung tissue. This decreases the number of air spaces and blood vessels in the lungs, though there is less airflow and resulting in less oxygen to critical parts of your body and ultimately causes death.




Cigarette smoking can be very damaging to your circulation system. Because the tar and nicotine in cigarettes contain harmful chemicals. Your bloodstream is infected by them when you smoke. When these poisons enter your blood:

●       Your blood becomes thicker, and there are clots in it.

●       Your blood pressure and heart rate increase, causing your heart to work harder

●       Your arteries become thinner, which reduces the amount of blood carrying oxygen as it circulates to your organs.

Together, these changes to your body when you smoke increase the chance of your arteries narrowing and clots forming, which can cause a heart attack or stroke.


Digestive System


Smokers also have higher rates of pancreatic cancer. Even people who smoke but don’t inhale face an increased risk of mouth cancer called passive smoking.

Smoking also affects on insulin, making it more likely that you’ll develop insulin resistance. That puts you at increased risk of type 2 diabetes and its complications, which tend to develop at a faster rate than in people who don’t smoke.

Smoking contributes to many common disorders of the digestive system, such as heartburn and peptic ulcers, and some liver diseases. Smoking increases the risk of Crohn’s disease, colon polyps, and pancreatitis, and it may increase the risk of gallstones.

Smoking affect skin horribly!

Smoking reduces the amount of oxygen that gets to your skin. If you smoke, your skin ages more quickly and looks grey and dull. The toxins in your body also cause many problems regarding many skin diseases.

Smoking prematurely ages your skin by between 10 and 20 years, and makes facial wrinkling, particularly around the eyes and mouth. Smoking even gives you a sallow, yellow-grey complexion, and hollow cheeks, which can cause you to look horrible.


Respiratory system also affect largely:


Withdrawal from tobacco products can cause temporary congestion and respiratory discomfort as your lungs and airways begin to heal. Increased mucus production right after quitting smoking is a positive sign that your respiratory system is recovering.

Children whose parents smoke are more prone to coughing, wheezing, and asthma attacks than children whose parents don’t. They also tend to have higher rates of pneumonia and bronchitis.


Reproduction and fertility:

Smoking can cause damage to blood vessels that supply blood to the penis. It can also damage sperm, reduced sperm count, and cause testicular cancer.

For women, smoking can reduce fertility. One study found that smokers were over three times more likely than non-smokers to have taken more than one year to conceive. The study estimated that the fertility of smoking women was 72% that of non-smokers.

Smoking also increases your risk of severe cervical cancer. People who smoke are less able to get rid of the HPV infection from the body, which can develop into cancer.

Smoking while you are pregnant can lead to miscarriage, premature birth, stillbirth, and illness, and it increases the risk of cot death by at least 25%.


Stomach is most affected by smoking:


Smokers have an increased chance of getting stomach cancer or ulcers. Smoking can weaken the muscle that controls the lower end of your oesophagus and permit acid from the stomach to travel in the wrong direction back up your gullet; this process is also known as reflux.

Smoking is a significant risk factor for developing kidney cancer, and the more you smoke, the greater the risk.


 For example, smoke 10 cigarettes a day, you are one and a half times more likely to develop kidney cancer compared with a non-smoker. This is increased to twice as likely if you smoke 20 or more cigarettes a day.


Mouth and throat:

Smoking causes unattractive problems such as bad breath and stained yellow teeth, and can also cause gum disease and damage your sense of taste.

The most serious damage smoking causes in your mouth and throat is an increased risk of cancer in your lips, tongue, throat, voice box, and gullet. More than 93% of oropharyngeal cancers are caused by smoking.

Once you've been smoke-free for 20 years, your risk of head and neck cancer is reduced to that of a non-smoker
