Why Should You Give Up Smoking?
We’ve all heard the warnings about smoking being bad for our health, but what exactly makes it so dangerous? The risks go far beyond what’s immediately visible, impacting nearly every organ in the body.
Understanding the harm caused by smoking is the first step in making a life-changing decision to quit.
What is a Cigarette Made Of?
A cigarette is made up of three primary components:
- The Filter: Often referred to as the “cigarette butt,” it is designed to reduce the number of toxins inhaled, but it doesn’t eliminate them.
- Rolling Paper: This thin paper holds the tobacco together.
- Tobacco Blend: Comprised of dried and processed tobacco leaves and stems, this is the substance that delivers nicotine and harmful chemicals. The primary plant used in tobacco production is Nicotiana tabacum.
What Happens When You Light a Cigarette?
Once lit, a cigarette releases over 7,000 chemicals in the form of small particles and gases. As the smoke passes through the filter, some of these particles are trapped, but the filter is not strong enough to remove all of them. One of the most notorious substances in cigarette smoke is tar, which is a sticky, brown substance that causes yellow stains on teeth, nails, and even vocal cords.
Cigarette Smoke and Your Lungs
The lower airway in our lungs is lined with cilia, tiny hair-like structures that help move debris and bacteria out. Cigarette smoke contains hydrogen cyanide, which paralyzes these cilia, allowing smoke to travel deeper into the lungs. The smoke carries cancer-causing chemicals like arsenic and benzopyrene, which coat the airways and increase the risk of lung cancer.
The smoke eventually reaches the alveoli, or air sacs of the lungs, where oxygen is exchanged for carbon dioxide. Unfortunately, cigarette smoke also contains carbon monoxide, a toxic gas that interferes with this exchange. It binds to hemoglobin in the blood, preventing it from carrying oxygen, and replacing it with carbon monoxide. This leaves body cells starved of oxygen, causing inflammation and narrowing of the airways, making it harder to breathe.
The Systemic Effects of Smoking
When the chemicals in cigarette smoke enter the bloodstream, they travel to various organs, spreading damage beyond the lungs.
- Blood Vessels: Oxidizing chemicals in smoke damage the blood vessels, leading to inflammation and the formation of fatty plaques. These plaques narrow blood vessels and can block critical ones that supply oxygen to the heart and brain, increasing the risk of heart attacks and strokes.
- Other Cancers: Metals like arsenic and radioactive substances like polonium travel through the bloodstream, increasing the risk of cancers in other organs, including the skin, liver, kidneys, and bladder.
Nicotine and Addiction
So, why do people continue smoking despite knowing the dangers? The answer lies in nicotine, the addictive substance in tobacco.
Within seven seconds of smoking a cigarette, nicotine-rich blood travels from the lungs to the brain, where it activates nicotinic acetylcholine receptors. This triggers the release of brain chemicals like dopamine, adrenaline, and serotonin, which create feelings of alertness and relaxation. This temporary “buzz” is what makes smoking so addictive.
However, nicotine only stays in the body for a few hours, and once it exits, cravings begin. Withdrawal symptoms can include restlessness, anxiety, and insomnia. Over time, the brain develops a tolerance to nicotine, meaning smokers need more of it to experience the same effects, creating a cycle of addiction.
The Rollercoaster of Smoking
Smoking exposes your brain and body to a continuous cycle of stimulation and withdrawal, making quitting even harder. In Australia, for example, smokers smoke an average of 93 cigarettes per week, which amounts to 4,836 cigarettes per year—an expense equivalent to buying four new iPhones.
The long-term effects of smoking include emphysema, wrinkling of the skin, loss of smell and taste, and even impotence. Tobacco is the only legal drug that kills its users when used as intended. In the U.S., over 95% of smokers started before the age of 21, highlighting the importance of preventing smoking in young people.
What’s the Good News?
The good news is that the number of smokers worldwide is decreasing. With the help of the internet and stronger tobacco control laws, quitting smoking has become more accessible than ever before. More and more young people are becoming informed about the dangers of smoking, which could lead to a future where smoking is no longer a societal norm.
If you’re currently smoking and thinking about quitting, you’re already halfway there. Making the decision to quit is the first and most important step.
