You must have heard the saying that a drop of nicotine can kill a horse. This sentence has caused many people to fear nicotine. Such exaggerated claims are often used in various quit-smoking advertisements to get smokers to quit cigarettes. Still, the actual harm caused by nicotine to the human body has little to do with it.
Nicotine exists in many substances in nature, such as tomatoes, eggplants, potatoes and many other vegetables that we are familiar with, which all contain more or less nicotine. You may be surprised that goji berries, the healthcare ingredient advertised by doctors, also includes a small amount of nicotine.
If the nicotine is injected, it is toxic enough to kill people. The nicotine from 15-20 cigarettes is extracted and injected into the vein. But I want to remind you that inhaling smoke containing nicotine and the effect of intravenous injection on the body are not the same.
Medicine has been advancing, and more and more data show that cigarettes are likely to bring severe physical diseases, such as lung cancer, emphysema and cardiovascular disease, mainly from cigarette tar. Still, the harm of nicotine to the human body cannot be compared with it. The British Department of Public Health has researched and released a report for this purpose. The report mentioned that tar-free e-cigarettes are at least 95% less harmful to the human body than cigarettes. Please pay attention to this exaggerated but accurate data. , What’s more, interesting is that the nicotine content in vaping is far less than that in cigarettes, and even e-cigarettes may not contain nicotine.
Some studies say nicotine has adverse effects on the cardiovascular system and affects our brain development. Am I deceived?
No, you’re not being lied to, that’s true, but you’ve probably overestimated its actual harm after seeing a lot of evil media hype. Nicotine is essentially a stimulant. When it enters the human body, it will stimulate peripheral vasoconstriction, resulting in a faster heartbeat, higher blood pressure and faster breathing and other physiological reactions, increasing the risk of cardiovascular diseases such as hypertension and stroke.
I’m not saying it’s harmless, but the truth is that any stimulant carries the same health risks, including the coffee you’re drinking right now. Coffee contains another common stimulant: caffeine.
Caffeine and nicotine have almost the same effect on the human cardiovascular system; they act on the central nervous system. But strangely, we don’t see any packaging labels suggesting health risks. How can this be explained? Is the business intentionally concealing it? Or, everyone agrees that low doses of caffeine do not cause health problems.
If some friends say they don’t like coffee, that’s fine. In addition to coffee, green tea also contains caffeine, even higher than coffee.
Nicotine affects adolescents’ brain development, especially in the brain’s language processing, memory and other functions, which can be found in relevant medical evidence. But caffeine can also affect brain development, so when banning teens from e-cigarettes, should they also be urged to drink less or no coffee?
At present, all the facts about the harm of nicotine are exaggerated. This is because of the public health campaign that began in the 1960s. At that time, to promote smoking cessation, various governments in the United States and Europe deliberately exaggerated the toxicity of nicotine and explained the harm out of context. If you pay attention to what the medical world says about nicotine, nicotine is used in treating Parkinson’s, Alzheimer’s, and attention deficit disorder, to name a few.
It is very irresponsible to say only toxicity without talking about the dose, but we still have to be careful about the possible health risks of nicotine; of course, if you are not addicted to smoking and have no plans to try e-cigarettes, that is the best thing.
