Q1: Why are there fewer and fewer big smoke players?

First of all, due to the impact of national policy, the online platform prohibits the sale of all e-cigarette-related items, due to operational difficulties, resulting in fewer and fewer brick-and-mortar stores, large smoke player attrition can not be replenished, and small cigarettes because the use of more convenient, simpler structure and more purchase channels, so the market has basically turned to the small cigarette market.

Q2: Can electronic cigarettes pass the airplane security checks in the end?

Not more than 100ml of vape oil and small e-cigarettes, the general security check is no problem, but only to bring the plane, not smoking, not more than the energy of 100wh (watt-hours) of lithium batteries can be carried, energy more than 100wh but not more than 16wh of lithium batteries need to be approved by the airline, and not more than two, energy more than 160wh of lithium batteries to prevent carry or mail. So we must look at the battery capacity of the big smoke e-cigarette we are carrying before we get on the plane, but if we encounter special events security upgrades, we may not be allowed to bring bottles of tobacco oil, but the small e-cigarettes currently on the market are basically able to carry.

 

Q3: electronic cigarettes why does smoking more throat will be dry?

The main component of cigarette oil is vegetable glycerin, glycerin has water absorption, high-temperature atomization will take away the moisture in the mouth, the natural tongue and throat will have a dry feeling, glycerin (VG) and propylene glycol (PG) are highly absorbent substances, each person’s oral saliva secretion capacity is different. PG and VG are healthy food additives, flavors and fragrances mainly provide a variety of flavors, and nicotine provides a sense of relief and throat hit.

 

Q4: Is there any harm in secondhand smoke from e-cigarettes?

E-cigarette smoke is mainly atomized by vegetable glycerin, which is basically harmless to humans, and e-cigarette smoke does not have tar carbon monoxide, and other major harmful substances of secondhand smoke. However, the different components of the cigarette and tobacco oil may contain trace or constant amounts of heavy metals, which are relatively active and can be oxidized to metal ions in an aerobic environment and at room temperature. Metal ions can be dissolved in the smoke oil, and with the smoke oil atomization, into the smoke aerosol thus being inhaled. And metal ion migration is often spoken of in electrochemistry and is an electrochemical phenomenon related to the solution and potential, the solution is conductors, and metal ion migration is very obvious. Simply put, the electronic cigarette oil body is originally insulated, but because of the presence of water molecules, in the energized conditions, metal ions will move from one pole to the other pole, constituting a metal or metal compound, this phenomenon also exists in the PCB circuit board. The heater wire, if oxidized to produce metal oxides, will also react chemically with some acids in the smoke oil, turning into organic metal compounds into the smoke oil and finally into the aerosol. This means that the metal in the smoke does not necessarily mean granular, but also includes heavy metal ions. In the country, there are many testing institutions that can do heavy metal testing, and the draft of the suspected national standard also provides for strict heavy metal emission standards, if because of an as yet unconfirmed pathological study of the electronic cigarette black hat, then it is likely to lead to the excessive interpretation of the mass media, which in turn will cause many people do not understand the electronic cigarette and panic.

 

Q5：Why does e-cigarette smoke trigger smoke alarms?

 Smoke alarms test the concentration of inhalable particles in the air, also known as PM2.5. When the concentration of PM2.5 in the air exceeds the standard, the smoke alarm will be triggered, and the smoke from e-cigarettes will trigger the smoke alarm even though it is not generated by combustion. At present, the U.S. TIF smoke sensor is to monitor the concentration of smoke to achieve fire prevention, smoke alarms usually use ion smoke sensing inside, ion smoke sensor is an advanced technology, stable and reliable work sensor, is widely used in a variety of fire alarm systems, performance is far superior to gas resistor type of fire alarms. Smoke sensors are used to detect the presence of smoke in the environment and the concentration of smoke, such as detecting smoke when a fire starts. The smoke probe encounters smoke or some specific gas, and its internal resistance changes, producing an analog value that can be controlled. Smoke sensors use the principle that the smoke sensitive element is affected by the concentration of smoke (mainly combustible particles) resistance value change to send the host the corresponding analog signal of smoke concentration; smoke sensors are mainly ion smoke sensors, photoelectric smoke sensors, and gas-sensitive smoke sensors; among them, ion detectors by the formation of uncharged particles after ionization charged particles (ions), so-called ion smoke detector, suitable for open fire detection; photoelectric smoke sensor detection cavity is set up with an optical sensor (emitting light source and photoelectric receiver), smoke into the detection cavity will block the light emission and scattering, the photoelectric receiver will receive the signal due to the scattering of light and change, followed by a change in the current signal; the gas-sensitive smoke sensor is a sensor to detect specific gases. It mainly includes semiconductor gas sensors, contact combustion gas sensors and electrochemical gas sensors, etc., of which the most used is the semiconductor gas sensor. Its applications are mainly: detection of carbon monoxide gas, detection of gas, detection of gas, detection of Freon (R11, R12), detection of ethanol in breath, detection of bad breath in the human mouth, etc.; it converts the type of gas and its information related to concentration into electrical signals, and according to the strength of these electrical signals, information related to the presence of the gas to be measured in the environment can be obtained, thus It can detect, monitor and alarm; it can also form automatic detection, control and alarm system with a computer through the interface circuit. U.S. TIF sensors are commonly used in home and factory gas leak devices, suitable for the detection of liquefied gas, butane, propane, methane, alcohol, hydrogen, smoke, etc.

Q6: Does smoking e-cigarettes in public places violate the relevant national regulations?

 On October 14, Shenzhen issued the first e-cigarette ticket on the mainland, and before that, the “Hangzhou Public Places Smoking Control Regulations” clearly included e-cigarettes in the control list. Many places introduced e-cigarette ban in Changsha, and public places smoking ban written in May this year began to implement the “Changsha City Civilized Behavior Promotion Regulations”. Although the regulations do not explicitly include e-cigarettes in the scope of control, in reality, in hospitals, subway stations, high-end office buildings, and other public places with strict tobacco control, e-cigarettes are also prohibited

Q7: Electronic cigarettes are electronic products or tobacco products?

At present, the state-issued clear regulations on the management of electronic cigarettes, although the electronic cigarette is an electronic product, but it is also one of the cigarette substitutes, to qualify the electronic cigarette, to wait for the introduction of a clear national policy before the definition.

Q8: Can e-cigarettes make people addicted?

Traditional paper cigarettes are addictive because they contain nicotine and tar, while e-cigarettes do not contain tar. In order to restore the feeling of paper cigarettes to the throat, e-cigarettes add a moderate amount of nicotine, which can produce a certain amount of addiction, but tar and carbon monoxide are the most deadly in paper cigarettes. The e-cigarette is a non-combustible electronic cigarette, which consists of a shell, mouthpiece, filter, flavor cartridge, light-emitting diode, power supply, and cap, which does not burn, contains only purified nicotine, does not contain tar, and does not contain the chemicals contained in ordinary cigarettes that cause respiratory and cardiovascular diseases.

 

Q9: Is the e-cigarette the culprit of the “popcorn” lung that appeared in the U.S. news?

Occlusive bronchitis (also known as popcorn lung), vitamin E acetate is the culprit of lung disease outbreaks, and all EVALI cases had vitamin E acetate in the lung fluid, one from multiple drug overdoses, one from fungal infections, and one from possible bacterial infections in the lungs. U.S. researchers tested lung fluid from 99 healthy people, including 18 e-cigarette users, and no one detected vitamin E acetate. In addition, they did not find vitamin E acetate in any of the nicotine-containing e-liquids they tested, so e-cigarettes were not the culprit in EVALI cases.

 

Q10: Is it an exaggeration or true that the UK news media reported that the switch from cigarettes to e-cigarettes helped improve heart health?

Professor Siegel in the UK said that there are very different causes of heart disease, including diet, alcohol abuse, and lifestyle habits, among others. However, Professor Siegel questioned the research project by Jacob George, Professor of Cardiovascular Medicine and Therapeutics at the University of Dundee, (by switching from cigarettes to e-cigarettes found that cardiovascular indexes improved by an average of 1.5 percentage points in one month, while combining the results of other studies that showed a 13% reduction in cardiovascular disease for every percentage point improvement in vascular function “) Because the study not only did not confirm that nebulization would raise cholesterol levels in the observed subjects but also did not clearly rank possible causes other than e-cigarettes, the switch from cigarettes to e-cigarettes helped improve heart health and is yet to be studied.

 

Q11: Do e-cigarettes contain formaldehyde?

Not all e-cigarettes produce formaldehyde in the process of use, but some of the player-grade devices that are revered by e-cigarette users can produce harmful substances such as formaldehyde. The principle of generating formaldehyde: 8 volatile carbonyl compounds generated by the cracking of propanetriol and propylene glycol, the main solvents in e-cigarettes are propanetriol and propylene glycol, at high temperatures, these two substances will produce a cracking reaction to generate formaldehyde, and most small cigarettes do not have enough heat to produce formaldehyde.
