Before that, some scientists renamed nicotine and said that nicotine is not a true carcinogen. It is enough to subvert the three views! Recently, a Harvard University study has subverted three more views, which is even more surprising!
Because, in the past hundred years, nicotine has been closely linked with "death" and "cancer", and it is said to be "the main harmful component of cigarettes." With the continuous advancement of science, we learned through clinical research that tar is the culprit of cancer, and carbon monoxide is the most harmful! Nicotine is not only found in tobacco leaves, but also in the fruits of many solanaceous plants. For example, tomatoes, gardenia and other plants contain nicotine, which is recognized as a healthy food for the human body. .
Since then, although some nicotine has been changed, nicotine is still considered to be addictive or dependent (one of the most difficult drug addiction). Public health officials are convinced that nicotine is addictive and has established regulations consistent with cigarettes to limit e-liquid

This is considered an addiction graph

However, a recent Harvard University study has broken this statement! Studies have shown that previous perceptions of nicotine addiction are not correct. Therefore, scientists do not agree with the opinions and practices of these health officials.
As early as July 2016, Harvard scientists published a study related to the so-called nicotine addiction, just as the US Food and Drug Administration announced relevant regulations.
The study found that the real cause of tobacco addiction is not nicotine but a chemical additive called pyrazine, which is used to improve the aroma of smoke produced by combustible cigarettes.

Pyrazine chemical formula
Different pyrazines produce different aromas, such as nutty, chocolate, etc., and most pyrazines are harmful to public health.
As for how pyrazines make cigarettes more addictive, scientists claim that it was because Big Tobacco Company was affected by a lot of negative news in the 1990s, which was the era of Clinton’s tobacco "sin tax." In order to reduce the harmfulness of combustible tobacco, Big Tobacco began to introduce low-tar cigarettes.
However, these low-tar cigarettes lack the rich flavor of traditional cigarettes until Big Tobacco found that pyrazine can significantly improve the taste of cigarettes. The study found that it is these pyrazines that make smokers addicted to nicotine instead of what everyone always thinks!

Compared to nicotine, pyrazine can increase the attractiveness of tobacco products and make it more difficult for smokers to withdraw.
Fortunately, as the first choice for the replacement of e-liquid does not contain this harmful chemical additives, as the British Royal College of Physicians concluded that e-liquid are more than 95% safer and healthier than cigarettes.
