What's more harmful, vape or cigarettes?

Of course, cigarettes, but we definitely do not recommend abusing vaping or using it for other purposes. If you have never smoked, then you do not need to start vaping

The most harmful thing in cigarettes is tar and combustion products. They are not in the vape, just as there is no combustion itself. And if you soar without nicotine, then there is none. Some harm can be dug up in glycine or fragrances, but such "chemistry" is now being shoved anywhere anyway.

Cigarettes. Vape liquids contain: glycerin 50-70% and propylene glycol 20-30%, and FOOD flavors. Okay, there may be an overdose of propylene glycol, BUT there is so little of it that for an overdose you need to soar for about 7-8 hours non-stop. Some liquids contain nicotine, it is the same as in cigarettes, only mg can be less. There are liquids and no nicotine. It will be more harmful to inhale the exhaust from the car than to vape the vape. But if they prove that Vape develops testicular cancer, then, of course, everyone will jump =) but not yet =)

In our country, no special research has been carried out.
Therefore, even the statements of various specialists are, in fact, only private opinion. No more.
I know of only one study on this topic in our country - the study of S.V. Tyutyunnikov from the Federal State Institution of Health of the Medical and Sanitary Unit of the Ministry of Internal Affairs in the Altai Territory.

In general, it says that: yes, electronic cigarettes are not harmless, but the harmful effects of their use are lower than from ordinary cigarettes. In addition, they allow you to replace the use of conventional ones without any problems.

As for the explosion of batteries: modern "electronics" usually have a lithium-ion battery in their filling. They work in the range from -40 to +50 degrees Celsius. And they do not have the property to explode, but only get very hot and flow. And then, only in case of curvature and inattention, or, in extreme cases, dementia of the user.
Just when using especially "powerful" devices, you should not turn off your own brain.

And most often the reason for damage to the battery and devices - it serves as a short circuit, due to the fact that it is quite simple to implement it on these things.

In Russia, using "electronics", it turns out, is no more dangerous than anywhere else in the world.

Cigarettes are more harmful to use. There is much more muck in the smoke than in steam, although there is muck there too. Cigarettes, on the other hand, don't explode, and this happens with vaporizer batteries. The risk of explosion increases when used in temperatures below 10 degrees Celsius and above 45 degrees Celsius. So vaping in Russia is more dangerous than in America.
