An international collaborative of nine professional organizations that promote respiratory health published a position statement on the health risks of electronic cigarettes in 2014. The statement outlined existing scientific data and advised caution until more information about the safety of the product is available. Various organizations, such as CSP Magazine and Newsweek, have taken the lead on addressing concerns about the e-cigarette.
The aerosols released from the electronic cigarette may damage airway epithelial cells in vitro and in animal models, suggesting a risk of long-term cancers. The inhalation of these aerosols has also been associated with increased pulmonary inflammation and decreased lung function. Chronic obstructive pulmonary disease has also been associated with electronic cigarette use, and studies in humans have linked prolonged exposure to these aerosols to chronic respiratory symptoms.
In addition to the relx e-cigarette device, the liquid used and user behavior affect the amount of nicotine emissions. Hence, researchers may need to use a combination of survey items to obtain detailed information about e-cigarette use and e-cigarette toxicant exposure. The exact survey items depend on the study population and the purpose. In some cases, novel approaches may be adopted to increase the quality of data collected. For example, they may incorporate user-uploaded videos and images.
An electronic cigarette contains nicotine and other chemicals as aerosols. These chemicals are known as contaminants. In some cases, the e-liquids may contain traces of other potentially toxic substances. They also contain flavorings that may be harmful for humans. A typical e-cigarette contains a battery, an atomizer, and a mouthpiece.
The composition of the e-liquid can also affect the amount of particulate matter emitted. One study found that e-liquids with 100% VG (vegetable oil) produce aerosol particles that are less than 0.1 micrometers in diameter. These aerosol particles could cause damage to the lungs if inhaled.
The e-cigarette’s composition affects particle size and concentration of nicotine in the aerosol. When e-cigarettes contain 50% PG and 50% VG, the distribution of nicotine particles remained consistent in both studies. However, when the VG content is higher, e-cigarette particles tended to accumulate at lower concentrations in the alveolar region. However, these differences are not meaningful when it comes to the potential absorption of drugs.
The use of electronic cigarettes has been increasing rapidly among young people in several countries. The United States National Youth Tobacco Survey found that nearly half of high school students and 500 000 middle school students used the product in 2015. In Oregon, it was the most common introductory tobacco product among students. Advertising and product design have played an important role in the rise of electronic cigarettes among young people.
The use of nicotine has long been associated with addiction, but vaping has a number of other risks. Research indicates that nicotine may affect the reward system in the brain, making drugs like cocaine more appealing. It is also known to alter the areas of the brain responsible for attention and learning, increasing the risk of mood disorders and impulse control problems. There are several states that have passed laws restricting the use of electronic cigarettes for minors.

How Toxicants From Electronic Cigarettes Affect Respiratory Health
