Even studies of the air in vape shops have shown that levels of toxicants are below occupational exposure limits. Those concerned with “thirdhand nicotine”—the unabsorbed nicotine that lands on floors and furniture—might make a case for not vaping around kids or pets who might lick the surfaces. According to a 2016 University of California-San Francisco study, 93.8 percent of the inhaled nicotine is retained by the user, and is not part of the exhaled vapor.
Who is most at risk?
Cutting out nicotine altogether will minimize the risk of nicotine-related side effects for you and others. Secondhand vape aerosol affects everyone, but certain groups may have a higher risk for negative health effects. “There [are] also aerosol products in e-cigarettes that could affect the respiratory function, and that may lead to worsened heart failure as well,” she said.

Can secondhand vape exposure be harmful?
E-cigs heat e-liquid with a small metal coil housed in an atomizer, and the heat turns the e-juice into the vapor you see. E-cigarette vapor doesn’t have any carbon monoxide or tar, and the particles in the aerosol are liquid rather than solid. Dangerous chemicals and metals are found in vapor, but only in tiny quantities. The levels of toxicants are minute compared to those found in smoke, which means the dangers of secondhand vaping are less significant.
flavorings such as diacetyl, a chemical linked to a serious lung disease

Not all views expressed in American Heart Association News stories reflect the official position of the American Heart Association. Boakye said people should minimize their exposure to vaping, ideally by leaving the area. And she urged people who vape to quit, noting that more funding is needed for vaping cessation programs.
Even if a vape liquid is advertised as being nicotine-free, it might still contain chemicals called nitrosamines, which are known to cause cancer. This is important because some flavourings, like diacetyl, which can be used to give a butter-like flavour to food, seem harmless when you eat them but can cause serious lung problems if inhaled. This is a chemical linked with popcorn lung, which has been seen in workers exposed to high levels of diacetyl in food factories. As a result, major popcorn manufacturers have removed diacetyl from their products.
If you encounter people vaping inside a house, all of the secondhand vapor you see comes out of the mouths of the vapers in the room. There is no side stream “vape smoke” like there is side stream tobacco smoke from cigarettes—no constant emission of vapor pouring from the device when it's not being used. And by the time the vaper exhales, the vapor contains much less of all the substances that were in the inhaled vapor, because most of it is absorbed by the user's mouth, throat and lungs. There simply aren't enough of the already-scarce toxicants left over to make secondhand vapor a concern.
Prevalence of wheeze, bronchitic symptoms and shortness of breath ranged from 12.3% to 14.9%, 19.4% to 26.0% and 16.5% to 18.1%, respectively, during the study period. Stronger associations were observed when analysis was restricted to participants who were neither smokers nor vapers. There were no associations with wheezing after adjustment for confounders. Exposure to outdoor PM2.5 is a well-established risk factor for respiratory and cardiovascular diseases (14). In most cases, the reported indoor PM2.5 levels during e-cig use are above 150 μg/m3, which are similar to those produced by t-cigs.
In secondhand vape, scientists smell risk
Schematic process from electronic cigarette emissions, to secondhand exposures, and to potential health effects. An electronic cigarette (e-cig) is a battery-powered nicotine delivery system widely used as an alternative to tobacco cigarettes (t-cigs). Since 2011, the global e-cig market has grown rapidly and is projected to reach $48.9 billion by 2025, more than 70% of the market being in North America and Europe (2). The number of e-cig users has also increased markedly, especially among adolescents, despite the US Food and Drug Administration (FDA)’s prohibition of sales to persons under the age of 18 (136).

While these compounds are released via the vapor and can build up on surfaces, they cannot enter other people's bodies or harm them (according to the previously mentioned study). The Food and Drug Administration (FDA) has approved propylene glycol in some products but it should be noted it has not approved the vaporized form of propylene glycol. Vaping creates chemical changes in the mouth that destroy good bacteria and allow bad bacteria to grow, increasing the likelihood of cavities, gum disease and cellular changes that can lead to cancer. Both are unsafe and harmful to your health, says Patrick Aguilar, MD, a pulmonary disease/critical care specialist with Endeavor Health. More research needs to be done in order to understand the side effects of nicotine-free vaping. Studies suggest that nicotine-free vaping can irritate the respiratory system, cause cell death, trigger inflammation, and harm blood vessels.
More than one in 10 Dallas ISD students sent to alternative schools as of Feb. 1 were removed from their home campuses because of e-cigarettes. The percentages are more striking in districts such as Duncanville and Mesquite, where around 40% of alternative school placements were for vaping. Chen said this study’s results add to the need to increase public awareness of the dangers involved in vaping and e-cigarettes. The vapor that is produced by an e-cigarette is almost completely composed of water.
This is called secondhand vaping, and there isn't a lot of published research yet on how inhaling this aerosol affects the body, especially among adolescents. According to the American Cancer Society, secondhand vape exposure may be harmful because people may breathe in substances such as nicotine and toxic chemicals within the vapor. This is because people can inhale the fine particles in vape aerosol, which may have health risks. For someone who already has a lung condition, exposure to secondhand vape aerosol can trigger symptoms and asthma attacks, and worsen the condition. “E-cigarettes contribute to inflammation and increase levels of lipids in the blood. These lead to atherosclerosis, a risk factor for many cardiovascular diseases including heart failure,” Bene-Alhasan added.
