Q & A
What is the primary reason people find it difficult to quit smoking?
-Nicotine is the main reason why it's difficult to quit smoking due to its highly addictive nature.
What are the withdrawal symptoms experienced by people who try to quit smoking?
-People who try to quit smoking experience withdrawal symptoms because their bodies have become dependent on nicotine.

-There are around 7,000 compounds involved when a cigarette is smoked.
What is the role of tar in the context of smoking?
-Tar is the name given to the suspended particles in cigarettes, which contain carcinogens and can cause yellowing of teeth, nails, and lungs.
How does carbon monoxide affect the body when smoking?
-Carbon monoxide can bind to hemoglobin more easily than oxygen, replacing it in the blood and leading to a reduced oxygen supply to vital organs, which can be fatal.
What is the impact of carbon monoxide on physical activities that require a lot of oxygen?
-Carbon monoxide makes the blood thicker, reducing the oxygen supply to organs like the heart and brain during activities that require a lot of oxygen, potentially leading to death.
What is hydrogen cyanide and how does it affect the lungs?
-Hydrogen cyanide blocks the body's natural process of removing foreign substances from the respiratory tract, allowing harmful chemicals to accumulate and damage the lungs.
What are some of the harmful substances that can accumulate in the lungs due to hydrogen cyanide?
-Harmful substances like hydrocarbons, nitrous oxide, organic acids, and others can accumulate in the lungs due to hydrogen cyanide.
Does smoking have any potential benefits according to the script?
-A study mentioned in the script states that smoking may reduce the risk of ulcerative colitis, a disease of the intestines.
What is the trade-off mentioned in the script regarding the potential benefit of smoking?
-While smoking may reduce the risk of ulcerative colitis, it increases the chances of developing Crohn's Disease, another intestinal disease.
What is the final call to action for viewers in the script?
-The script encourages viewers to share their opinions on whether to continue smoking, quit, or avoid starting in the comment section below.
Outlines
π¬ The Dangers of Smoking
This paragraph delves into the harmful effects of smoking on the human body. It starts by discussing nicotine's addictive nature and its role in making quitting difficult, leading to withdrawal symptoms. The paragraph then expands on the over 7,000 compounds in cigarettes, many of which are carcinogenic, highlighting the damage they can cause to various organs and overall health. The focus then shifts to tar, explaining its composition, its contribution to the yellowing of teeth and nails, and its ability to contaminate the lungs. The paragraph continues with carbon monoxide, detailing how it can fatally replace oxygen in the blood, leading to thickened blood and potentially fatal consequences during physical exertion. Hydrogen cyanide is also mentioned for its role in preventing the lungs from clearing foreign substances, allowing harmful chemicals to accumulate and damage the lungs. The paragraph concludes with a contrasting note on smoking's potential to reduce the risk of ulcerative colitis but increase the risk of Crohn's disease, prompting a discussion on whether the risks outweigh this single benefit.

Transcripts
We are all familiar with cigarettes
and how everyone says
that smoking is unhealthy.
But... actually,
how does smoking affect our bodies?
Let's start with the components.
First, nicotine.
A substance that is very addictive.
It's the main reason why it's difficult to quit smoking.
In fact, nicotine is why
people who try to quit experience withdrawal symptoms
and ultimately go back to smoking.
Besides nicotine,
there are around 7,000 compounds involved
when you light up a cigarette.
Some of these compounds will activate
and damage our bodies.
What's more,
there are more than 60 compounds
which are known to cause cancer.
From this, we can conclude that smoking
can damage many of our body's organs
and in general, cause declining health.
The next main component is tar.
This is the name given to the suspended particles in cigarettes.
These particles contain substances that can cause cancer,
also known as carcinogens.
Examples include metals such as
arsenic,
cadmium
and others.
The tar is sticky and brown in color.
So, have you ever wondered
why a smoker's teeth and nails can turn yellow?
Yep, it's because of tar.
Tar can also contaminate your lungs
and give it a similar yellow appearance too.
The next dangerous substance
is carbon monoxide.
In large quantities, this gas can be fatal
because it can replace the oxygen circulating in our blood.
How? Like this.
Our blood contains red blood cells.
And in the red blood cells there is hemoglobin.
For non-smokers,
oxygen binds to hemoglobin
which is then transported throughout the body.
However, carbon monoxide can also bind to hemoglobin,
and it does this more easily than oxygen.
So, carbon monoxide can easily replace oxygen.
You may be thinking,
"Well... so what?"
"What's the problem with oxygen being replaced by carbon monoxide?"
Actually... a lot of problems.
Carbon monoxide makes the blood thicker
and in activities such as running
that require a lot of oxygen supply,
important organs such as the heart, brain, and other organs
get very little oxygen and it can lead to death.
Another substance in cigarettes
is something called hydrogen cyanide.
Our lungs have tiny hairs called cilia
which help remove foreign substances
that have entered our respiratory tract.
Hydrogen cyanide blocks our bodies
from doing this process
and allows chemicals
such as hydrocarbons, nitrous oxide, organic acids
and other harmful substances in cigarettes,
to accumulate in our lungs and damage it.
Still, besides the fact that smoking damages the lungs,
heart,
blood vessels,
and even cause brain damage and strokes,
there is an interesting fact that not everyone knows.
A study states that smoking
reduces the risk of a disease called ulcerative colitis,
a disease of the intestines.
But, smoking also increases the chances of developing
Crohn's Disease.
A disease of the intestines too.
So, is being free from ulcerative colitis
worth the other risks?
Try getting your friends' opinions,
whether they are smokers or non-smokers,
by sharing this video with them.
Will you continue smoking or quit?
Are you thinking of picking up smoking?
Or staying far away from cigarettes?
Write your opinions in the comment section below.
Thank you and see you in the next video!
