What are Second and Third-hand Smoke and Vaping Aerosols


Although vaping is much better and safer than smoking, both have their own different outputs. Smoking generates second and third-hand smoke, whereas vaping produces vaping aerosols. These all three affect in one way or another but are harmful and noxious for human health.

Second-hand and third-hand smoke is created by tobacco products, especially cigarettes. When cigarettes are being ignited or smoked they make these dangerous smokes. On the other side, vaping aerosols are produced by heating a liquid that usually contains nicotine, present in the flavours, and other chemicals. Both vape devices, Puff bars and re-usable vapes bring out these smokes.

You might or not be familiar with these terms, to clarify you these all are to be discussed in this blog. First, it’s important to consider that these all result from heating or burning harmful substances, including nicotine. In spite of this fact, one of these is way less detrimental and very much safer than others. So which one did you guess? No, absolutely not. To know, keep reading and dive into a bit of detail, given below.

Defining Second-hand Smoke:

Do you smoke cigarettes? Whether you do or do not, you must have an idea that smoking generates toxic smoke that is deleterious to health. Right, it is a fact that it does not only cause life-threatening damage to the smokers but also to non-smokers surrounding the smokers. The smoke that is the cause is no other smoke that is known as second-hand smoke.

Generally, secondhand smoke is smoke from burning tobacco products, like cigarettes, cigars, hookahs, or pipes. Secondhand smoke also is smoke that has been exhaled, or breathed out, by the person smoking. It is not caused by any of the vapes, whether the disposable vapes like Elf bar 600 and Elf bar lost mary reusable ones.

Types of Second-hand Smoke

There are two types of second-hand smoke. Number one is the sidestream smoke and the other is mainstream smoke. The sidestream refers to smoke from the lighted end of a cigarette, pipe, or cigar, or other tobacco burning product such as hookah. The direct smoke from the tobacco burning in a cigarette is more injurious than the mainstream smoke.

The mainstream smoke is the smoke exhaled by smokers. It is the smoke breathed out by the person who is smoking, which can be inhaled by others. Both types of second-hand smoke is absent in vapes, including disposable vapes as well as reusable vapes.

Defining Third-hand Smoke:

Third-hand smoke as the name suggests is the third way the smoke emits from tobacco burning products, such as cigarettes, cigars, or hookah. Simply third-hand smoke is the second-hand smoke that sticks on the surfaces of objects, ages over time and gets more toxic as time passes.  Third-hand smoke is usually as poisonous as first-hand smoke (the smoke that is inhaled by the smoker).

Since it is produced through smoldering tobacco and directly released from the cigarette, it has the same harmful effects as first-hand smoke. The third-hand smoke clings to the objects, including clothes, furniture, walls, and other surfaces around, it stays for long periods of time even after the smoking has stopped.

Effects of Second and Third-hand Smoke:

As described above, both are extremely noxious for human health. Since these smokes generate from lighting up cigarettes or other tobacco-related products, these produce dangerous chemicals. The chemical comprises heavy forms of nicotine, carbon monoxide, hydrogen cyanide, formaldehyde, ammonia, arsenic, benzene, and thousands of other chemicals which are life-threatening and cause cancers.

These cause numerous health problems in people, counting cancer, heart disease, stroke, lung diseases, diabetes, and numerous other life-risking diseases. Furthermore these trigger health issues for infants and children, including more frequent and severe asthma attacks, respiratory infections, ear infections, and sudden infant death syndrome. Unlike the vaping aerosols, disposable vapes are less contagious and damaging.

Defining Vaping Aerosols:

The vaping aerosols are produced by heating the e-liquid used in a vape device. Both vapes devices, disposable vapes as well as reusable vapes create vaping aerosols. Vaping aerosols are generated when the e-liquid comes in contact with a coil heated to a specific temperature within a chamber, which is thought to cause pyrolysis of the e-liquid and could also lead to decomposition of other liquid ingredients.

The e-liquid that is heated in the vape device tank contains Propylene Glycol (PG), Vegetable Glycerine (VG), glycerin, nicotine, flavours, aroma transporters, and other substances. This is way less baleful than second-hand or third-hand smoke. In fact, this is safer than any form of smoke as this excludes countless harmful chemicals that smokes possesses.


If you at the threshold of making a decision whether you should be smoking or vaping or you are considering replacing smoke cigarettes with vaping disposable vapes, it is very crucial that you do analysis of the outcomes of both. You must consider the effects of smoking and vaping, which are mentioned above.

Smoking results in generating smoke, second-hand and third-hand which are adversely dangerous. While vaping outcomes in vaping aerosols which are less damaging due to many factors, mentioning one of which is that it doesn’t contain tobacco and other numerous lethal chemicals. Therefore choosing vapes is wiser decision and it is highly recommended to switch to disposable vapes.
