Vapes are electronic cigarettes that mimic the smoking experience of tobacco cigarettes. They contain a battery, atomizer, and a container that vaporizes liquid nicotine. Users inhale the vapor to get the “cigarette” effect. Vape users are commonly known as “vapers.”

Flavoring chemicals

A number of flavoring chemicals in e-cigarettes are linked to a variety of health problems, including damage to the lungs. The most common is diacetyl, which is commonly combined with other chemicals to produce the flavor. The chemical can be toxic in high doses, and it can lead to respiratory problems if inhaled for extended periods. Other chemicals, such as acetoin, may also cause respiratory problems.

Many people do not realize that the flavoring chemicals in vape juice are potentially harmful. But scientists have discovered that these chemicals carry over to the vapor that people inhale. One professor of anesthesiology at Duke University has studied the effects of some of these chemicals, and concluded that they may irritate the lungs in the long run. This is especially concerning given that people are not even aware they are inhaling these substances.

Formaldehyde

Researchers have recently revealed that vapor products may be causing elevated levels of formaldehyde in the air. The researchers say the concentrations are higher than those produced by cigarettes. The findings, however, come with a caveat: they were only able to determine the amount of formaldehyde through air sampling tests, which were conducted at a vape shop at the request of the shop owner.

While formaldehyde in vapors is not an immediate health risk, there is evidence that it may be a factor in the development of certain types of cancer. In addition, some e-liquids contain synthetic compounds called diketones. These chemicals can cause a health hazard known as popcorn lung. Although diketones are not present in all e-liquids, many flavours contain them. They are the source of the buttery taste of some e-liquids. Despite the risks, many vapers prefer a diketone flavour.

Second-hand exposure to nicotine

In a recent study, researchers found that second-hand exposure to nicotine from vaping was associated with an increased risk of bronchitic symptoms and shortness of breath in young adults. The researchers analyzed data from the Southern California Children Health Study cohort, in which 2097 young adults completed annual surveys regarding respiratory symptoms. The researchers controlled for factors such as the participants’ age, smoking status, and tobacco use.

The researchers found that the prevalence of second-hand nicotine vape exposure increased from 11.7% to 15.6% among the study population, while the prevalence of secondhand smoking decreased from 26.6% to 20.4% of participants reported past 30-day usage of tobacco, e-cigarettes, or cannabis, but the differences were not statistically significant. The researchers also found an increase in the prevalence of primary vaping among the study participants.

Health effects of second-hand vapour

There are a number of health risks associated with second-hand vapour, including increased risk of still birth, low birth weight, and early death for the infant. These risks are more severe for pregnant women, and it is recommended that they quit smoking before becoming pregnant and abstain from vaping while pregnant. Furthermore, the chemicals inhaled by pregnant women can enter breast milk and affect the child in later stages.

The effects of second-hand vapour are not fully understood. There are a number of theories as to how it can affect the health of people around a smoker. A study by RTI International found that it may trigger an inflammatory process in the human respiratory system. In fact, mercury has been found in second-hand vapour, and the city of Calgary has proposed a ban on vapes public spaces.
