Popular Science: Which is the most dangerous of electronic cigarettes and traditional cigarettes?
At the 315 party in 2019, e-cigarettes were exposed. According to reports, e-cigarettes also release harmful substances, which endanger the health of smokers and passive smokers. Prolonged smoking of e-cigarettes can also cause dependence on nicotine. Some e-cigarette liquids have non-standard nicotine content labels, and some have excessive nicotine content. The smoke liquid contains formaldehyde, propylene glycol and glycerin.
So which one is the most harmful? Let's first look at the difference between e-cigarettes and traditional cigarettes
What they have in common: both contain nicotine. (E-cigarettes that do not contain nicotine are currently on the market)
The main ingredients in traditional tobacco: cut tobacco, tobacco flakes, flavors and fragrances, moisturizers, filters, cigarette paper.
Ingredients contained in electronic cigarettes: atomizers, functional devices (poles, boxes, etc.), e-liquid (PG/VG, flavors and fragrances, nicotine)
Compare the hazards from each component. Smoking cigarettes releases nicotine by burning shredded tobacco, and the human body absorbs nicotine.
Whether smoking or e-cigarettes, the goal is actually to obtain nicotine. When nicotine enters the body, it will be transported through the blood and can pass through the blood-brain barrier. It only takes an average of 7 seconds to reach the brain after inhalation. The half-life of nicotine in the human body is about 2 hours. The liver is the main organ that metabolizes nicotine, and the decomposing enzyme is Cytochrome P450.
In recent years, many domestic and foreign experts believe that the nicotine in cigarettes does not have much harm. The real carcinogens are tar and carbon monoxide. (Nicotine is not only found in tobacco leaves, but also in the fruits of many solanaceous plants. For example, tomatoes, medlar and other plants contain nicotine, and these vegetables and medicinal materials are recognized as healthy foods that are beneficial to the human body. .)
The shredded tobacco in traditional tobacco is tobacco products. At present, the main types of cigarettes sold in my country are flue-cured tobacco. According to the "Statistics of Tobacco Planting Resources Modified Tobacco Leaves 1998-2004" published by China Tobacco Group, the average content of chemical components in flue-cured tobacco are: total sugar 23.8%, reducing sugar 19.63%, total nitrogen 2.00%, nicotine 1.99%, protein 10.32%, Schmuck value 2.45%, total sugar/nicotine 14.21%, total nitrogen/nicotine 1.15%. Tobacco also contains trace amounts of radioactive substance polonium-210.
The main harmful substances to the human body are substances produced by combustion. The burning of cigarettes can produce more than 7000 kinds of chemical components, of which more than 250 kinds of toxic and harmful substances, such as: tar (carcinogen and carcinogen), benzopyrene (highly active indirect carcinogen), heavy metals (Cd, Cr, As , Pb, etc.), gas pollutants (carbon monoxide, acrolein, hydrocyanic acid, nitrogen monoxide, nitrogen dioxide, acetone, sulfide, ammonia, phenol, acetaldehyde, etc.)
E-cigarettes only contain a certain amount of nicotine. The nicotine in e-cigarettes belongs to free nicotine or nicotine salt, which is essentially different from the nicotine in traditional burning tobacco. To be precise, the chirality of nicotine is different. The nature is different but the harm is the same, but the nicotine in e-cigarettes has a low transfer rate and a high metabolic rate. According to the standards of other countries (FDA as an example), the nicotine content in e-cigarettes has a safe range. Currently, vitavp products meet the safety standards!
Except for nicotine, glycerol, propylene glycol, flavors and fragrances all use food-grade additives. But the aerosol of electronic cigarettes is not completely harmless. They contain some tiny particles that may cause cancer, and they may also contain some heavy metals, volatile compounds. Some studies also show that e-cigarettes increase the risk of heart disease and cancer
According to a study in the Journal of the American Medical Association (JAMA), e-cigarettes have 98% less harm to the human body than cigarettes.
In February 2018, the American Cancer Society (ACS) also issued a position statement: Although the long-term effects of e-cigarette use are not clear enough, it can be estimated that it is less harmful than ordinary cigarettes. The association clearly encourages people to try to use electronic cigarettes instead of traditional cigarettes. The association also recommends that clinicians recommend e-cigarettes to smokers to replace traditional cigarettes. Of course, e-cigarettes are only a transitional state, and quitting smoking should always be the first choice
In November 2018, the US Centers for Disease Control and Prevention (CDC) also revealed its attitude to the public. It recommends that people who are already addicted to cigarettes switch to e-cigarettes and try to quit smoking. But it also reminds that e-cigarettes are not harmless. Teenagers, pregnant women, and people who do not smoke should not try because it is less harmful than cigarettes.
In 2015, the Public Health Agency of England (PHE) released a 113-page report that analyzed the various risks of e-cigarettes in detail. The report concluded: e-cigarettes are 95% safer than smoking. Policies should encourage smokers to use e-cigarettes. As a key tobacco control strategy to reduce the harm caused by smoking.
After weighing the pros and cons of public institutions in the United Kingdom and the United States, they all tend to believe that e-cigarettes are better than cigarettes for smokers.
To sum up: e-cigarettes are not completely harmless, but smaller than cigarettes
