What Are E-Cigs Made Of?
E-cigarettes typically consist of three main components: a battery, an atomizer, and a cartridge filled with e-liquid. This liquid usually contains nicotine, flavorings, and other chemicals. While the absence of combustion in e-cigs seems beneficial compared to smoking, it is the heating of these e-liquids that can lead to the production of harmful substances.
The Science Behind E-Cig Vapor
When the e-liquid is heated, it undergoes a chemical reaction that can produce aldehydes, a group of chemicals that include formaldehyde. Formaldehyde is a known carcinogen, and its presence within e-cig vapor raises concerns about long-term exposure and associated health risks.
Additional studies have shown that certain flavorings used in e-cigarettes can break down into potentially harmful substances. For instance, the breakdown of flavoring agents like diacetyl and acetyl propionyl can lead to serious lung conditions, such as popcorn lung, a disease linked to breathing difficulties and lung damage.
Health Impacts and Misconceptions
Although e-cigarettes are often marketed as a healthier alternative to smoking, there is growing evidence to suggest otherwise. Many users of e-cigs are unaware of the dangers posed by the chemicals generated during vaping. The misconception that e-cigarettes are harmless is partly due to the marketing strategies employed by companies, which emphasize the product as free of the many additives found in traditional cigarettes.

Long-term inhalation of e-cig vapor can lead to lung irritation, cardiovascular problems, and, as research continues to unfold, possibly increased cancer risk.
Moreover, nicotine, often present in e-liquid, is highly addictive and poses a range of health issues, including but not limited to increased blood pressure and heart rate.
