What is an aerosol?
An aerosol is a mixture of solid and/or liquid particles suspended in a gas. Aerosol examples include morning fog, mist from a spray bottle, or smoke from an active volcano. The smoke from a cigarette and the vapor from a Reduced-Risk Product ( RRP )* are aerosols as well.
What is e-cigarette aerosol made of?
This aerosol is made up of tiny particles, some of which may contain toxic chemicals that are created when the e-liquid in e-cigarettes is heated. The aerosol may then be breathed deeply into the lungs –– along with the chemicals –– and exhaled.
What chemicals are in vape aerosol?
Also, toxic chemicals like formaldehyde, acetaldehyde, and ultrafine particles have been found in vape aerosol. These chemicals have big names, but what are they exactly?
What is the difference between smoke aerosol and vapor aerosol?
However, smoke aerosol and vapor aerosol have completely different characteristics Smoke aerosol is generated at high temperatures in complex thermal processes (“combustion”) and, as a result, contains a large number of constituents.
Is vaping aerosol or vapor?
Even though term 'vapor' is normally used, vape devices do not produce water vapor. Vaping produces an aerosol mist. Unlike water vapor, the aerosol mist includes ultra-fine particles that are breathed into the lungs.
Do Vapes produce aerosol?

How do Vapes create aerosol?
The aerosol of e-cigarettes is generated when the e-liquid comes in contact with a coil heated to a temperature of roughly 100–250 °C within a chamber, which is thought to cause pyrolysis of the e-liquid and could also lead to decomposition of other liquid ingredients.
Is smoke an aerosol?
An aerosol is a suspension of fine solid particles and/or liquid droplets in a gas (usually air). Cigarettes generate a smoke aerosol that is the result of the combustion (burning) of tobacco, and contains carbon-based solid particles. While smoke is an aerosol, not all aerosols are smoke.
Do Vapes have formaldehyde?
Formaldehyde is produced by thermal degradation in e-cigarettes. Dry puffs result from overheating and create an unpleasant taste that users avoid. In realistic conditions, formaldehyde in e-cigarettes is lower than cigarette smoke. High levels of formaldehyde are produced in unrealistic (dry puff) conditions.
Do e-cigarettes leave a residue?
Vaping does leave a residue on walls that can attract dirt, however any staining typically takes a long time to build up, and stains can be easily cleaned off using a wet cloth. If you want to minimise staining even further, try vaping near an open window, or in a room with plenty of ventilation.
Why is nicotine so bad?
But why is nicotine so bad? Nicotine is the addictive chemical in cigarettes and most vapes. Addictive chemicals trick your brain into thinking it’s getting something good. And teens can get hooked on nicotine more easily than adults. Plus, nicotine is as addictive as heroin, cocaine, and alcohol! Which means quitting (smoking OR vaping) is hard to do. For teens, it gets worse; nicotine can harm your brain development, which may affect comprehension, critical thinking, attention, learning, and mood. Plus, nicotine raises your blood pressure and increases your heartbeat.

This is a rodent-equivalent of a common clinical measure in humans in the brachial artery, the major blood vessel of the (upper) arm,” Springer said. “It is known that e-cigarettes can impair vascular function in humans. If any mist or aerosol that rats inhale has this adverse effect, it will likely happen in humans, too.”
Is vaping harmful?
Vaping, or the use of e-cigarettes, is often promoted as a less harmful alternative to smoking traditional cigarettes.
