China Tobacco fights back: debunking the myth that one e-cigarette equals ten cigarettes

What were the results after the mice smoked aerosol smoke for 90 days?

No significant toxicity to ratsSexual effect!!!

It has always been rumored that "smoking one e-cigarette is equivalent to smoking ten cigarettes", which is simply alarmist.

First-class carcinogens, betel nut, tobacco, wine, and salted fish, are always eaten by humans

But I am very afraid of e-cigarettes.

Cigarettes have existed for hundreds of years, and there have been many results on how many harmful substances there are and how harmful they will be to the human body.

#p#Pagination Title #e#In the past two years, research on e-cigarettes has gradually increased

The China Tobacco national team began to scale up the big move and conduct special research.

Recently, Xiao Wang, the five-leaf god, Lami, discovered two e-cigarette papers about Zhongyan

Specialized in research on [Toxicity of E-cigarette Tobacco Oil]

conclusion"No significant toxic effects on rats"。

#p#Pagination Title #e#1. Ask mice to draw large doses of propylene glycol and glycerol for three months

1. Rats were allowed to pump propylene glycol for 90 days

2. Rats were given glycerol for 90 days

So what are propylene glycol and glycerol?

Tobacco liquid is mainly composed of four components, namely propylene glycol (PG), glycerol (also known as glycerol, VG), essence and nicotine.

#p#Pagination Title #e#Propylene glycol and glycerol together usually account for more than 80% of the smoke liquid, and some can reach 90%. The remaining 10% to 20% can be distributed to other ingredients such as essence, nicotine, and alcohol. Respect science and facts.

The main ingredient of the well-known caisel is also glycerol。In other words, if you don't dislike Kaisai dew and don't care about the taste, you can also try it on a tobacco rod.

Propylene glycol (PG) is a by-product of petroleum that is colorless, odorless, sparse, and slightly viscous. PG is a good flavor carrier and can absorb more flavors in solution. It is also called a "fragrance carrier" by many people in the industry. This is also the reason why some high-PG cigarette liquids have stronger flavors and stronger aromas. The PG ratio can also affect the feeling of throat strike.

#p#Pagination Title #e#In fact, PG is very common in life. "GB 2760-2014 National Food Safety Standards for the Use of Food Additives" stipulates that propylene glycol is used in raw and wet flour products.(such as noodles, dumpling skins, wonton skins, and steamed wheat skins) The maximum usage requirement is 1.5 g/kg, and the maximum usage requirement in pastry production is 3.0 g/kg; in terms of oral drugs, the threshold dose for daily PG intake by adults can be as high as 25 mg/kg/day; in terms of daily cosmetics, according to the 1993 American Cosmetic Ingredient Review (CIR) report, it was concluded that PG concentrations up to 50% can be safely used in cosmetic products.

However, oral intake of excessive doses of PG may also cause cardiovascular and renal failure, central nervous system abnormalities, acid-base abnormalities and hyperosmolar symptoms. Transdermal exposure to excessive PG may also cause skin allergies. Exposure to other special routes such as intravenous injection of PG may also cause adverse reactions.

Glycerine (also known as glycerin, or VG for short), which is commonly called "Vegetable Glycerin" in Chinese, is a natural chemical extracted from vegetable oil. Vegetarians can also safely use the ratio of VG means high viscosity. Using a high VG liquid means you will consume more tobacco oil when you smoke steam cigarettes. Therefore, VG is also called the "fog maker". The ratio of VG also affects the smoothness of the smoke inlet.

Glycerol is a colorless, transparent, odorless, and sweet viscous liquid. Due to its moisturizing, plasticizing, seasoning, thickening, and anti-corrosion effects, it is widely used in tobacco, cosmetics, coatings, textiles, food and medicine. In traditional cigarette products, 1% to 5% glycerol is usually used as a moisturizer and a surfactant for tobacco flavors and fragrances.

#p#Pagination Title #e#The experimental conclusion of propylene glycol is that the NOEL value of PG inhaled in rats for 90 days is 100 mg/kg, and long-term inhalation of lower doses of PG has no significant toxic effect.

The experimental conclusion of glycerol was that rats inhaled glycerol through the nose for 90 days and did not produce significant toxic effects on rats at an exposure dose of 750 mg/kg.

Common e-cigarette cartridges on the market generally cost 2ml/capsule.

In the propylene glycol experiment,low dose groupIt's equivalent to letting mice smoke 50 cigarette bombs for 90 days. One cigarette bomb for two days. The mid-dose group actually smoked 250 cigarettes, and the high-dose group smoked 750 cigarettes.

In other words, 120 mice smoked 375 cigarettes, 50 cigarettes, and 5 cigarettes respectively over 90 days. Then we used the highest dose of data to tell us that high doses of inhaled glycerol had no significant toxic effects on rats!# p#pagination title #e#

For the sake of human health, the little mouse crazily tried to smoke e-cigarettes brought us this set of data. Please remember:

The main components of e-cigarette liquid, propylene glycol and glycerol, will not have toxic effects on the human body if long-term use of higher doses!

Finally, let us thank the little mouse and our country for its rigorous experiments!
