This year, Nature Communications published a disruptive study, the Shenzhen Institute of Advanced Technology of the Chinese Academy of Sciences found through experiments that ingesting low doses of nicotine can reverse aging and prolong life by 40%.
As a result, there are people everywhere on the Internet who advocate that "smoking is beneficial" and that they can even "smoke more and longer the longer".
But is that really the case?

Nicotine may extend life by 40%
Before we get into the nitty-gritty, let's take a look at the details of the experiment.
The study subjects of this experiment were mice, and by increasing the low dose (2 micrograms) of nicotine in drinking water, the NAMPT activity and NAD+ synthesis of male mice were improved, and glucose metabolism and cognitive function were further corrected, and the aging reversal was achieved.
What's more, this experiment is oral nicotine with water, which is not directly inhaled, but slowly absorbed by the stomach and intestines, and part of it is metabolized by the liver.
Finally, the nicotine content in the blood of the mice was 0.25 nanograms per milliliter.
And what is the amount of nicotine in the blood of the average smoker?
It is 10-50 nanograms per milliliter, and many old smoking guns can even exceed 500 nanograms per milliliter, which is more than 1,000 times different from the dose used in the experiment.
Therefore, experiments have found that very low doses and slow intake of nicotine do have a positive anti-aging effect on the body, but as soon as the dose of nicotine is high, it has negative neurotoxic effects.
Compared with the experimental dose, smokers inhale a high dose of nicotine, which is more toxic than the benefits.
Since then, even if the many positive effects of nicotine have been confirmed, it is still prioritized to make the right amount of medicine, rather than encouraging others to smoke.

—The Second—
Nicotine is not carcinogenic, but it is an accomplice in "killing" health
Nicotine is a colorless, oily substance that is the fastest addictive drug because a single cigarette can make a person addictive.
It metabolizes extremely quickly, it can metabolize 75% in an hour, and after smoking one, withdrawal symptoms will soon appear.
This withdrawal symptom does not manifest itself in physical pain, but in a mental emptiness, a feeling that something is missing.
The satisfaction of smoking is the result of the loss of emptiness.
Many people say that "a cigarette after a meal is a race against a living immortal".
Have you ever observed that non-smokers are a light-hearted and satisfying thing in themselves after eating.
A non-smoker can relax directly, whereas a smoker needs to relax through a cigarette.
That's when the dangers of cigarettes really come to light.
Because nicotine itself is not carcinogenic, tobacco mixtures contain more than 7,000 different chemicals.
Once burned, they are released in the form of small particles and gases.
Carcinogens such as tar, arsenic and benzopyrene can coat the lining of the airways and enter the lungs, significantly increasing the risk of lung cancer.
When you become addicted to smoking every day, these harmful substances will be absorbed into the bloodstream, and the damage to the body caused by cigarettes is no longer limited to the lungs -
Oxidizing chemicals react with the inner wall of blood vessels, resulting in inflammation and fatty plaques, inducing vascular infarction;
Metals such as arsenic enter the bloodstream and increase the risk of skin cancer, liver cancer, kidney cancer, etc.
Exaggerated propaganda abounds, but the harm of smoking is far from overstated.

—The Third—
Don't replace cigarettes with e-cigarettes
Objectively speaking, the health hazards of e-cigarettes are lower than those of cigarettes.
Because e-cigarettes are actually glycerin atomization, not combustion.
Therefore, the smoke spit out is actually glycerin, propylene glycol, flavors and other substances, and tar is less carcinogen.
But e-cigarettes have a particularly big problem - it greatly lowers the entry threshold for smoking.
Ordinary people will definitely feel stinky and choking when they smoke for the first time, just like the last sentence, and they will definitely not feel enjoyable.
Unless you are curious again and again, smoke a few times, and get poisoned with nicotine, it is difficult to actively continue to smoke.
But if your first experience is a fruit-flavored vape, then you will simply accept it.
I even think these flavors are very interesting, like small snacks.
As a result, the threshold of smoking suddenly changed from the need to jump over to a simple act that can be crossed with one step.
And to make e-cigarettes more harmless, many merchants package it like a snack.
But no matter how similar it is, it's not really food, but smoke that actually contains nicotine.
Once you become addicted, one day you will find that e-cigarettes are not exciting enough.
Well, that's when cigarettes come and give you a shock of tar and carbon monoxide, stimulating the guts and brain, and the need for a threshold is getting higher and higher.
From one or two sticks a day, to one pack a day later, and then became a "smoke fruit ability" in the new era.
Overcoming nicotine addiction is difficult, and the best thing to do is not to pick up the first cigarette and not hand one to someone else.
Not smoking, smoking, is our attitude towards tobacco.
