Chapter 1: The Nature of E-Cigarettes

Using an e-cigarette can be likened to inhaling fog from a concert.

One common question arises: Are e-cigarettes significantly less harmful than conventional cigarettes? Many assume that since it doesn’t feel like traditional smoking, it must be safer. However, this assumption is misleading. What users inhale is not vapor; rather, it is an aerosol, akin to the mist produced at concerts, primarily composed of glycerol and propylene glycol. Thus, using an e-cigarette without nicotine might be comparable to breathing in concert fog. In this discussion, we aim to clarify the realities surrounding e-cigarettes, focusing on the chemical makeup of the liquids and their implications for human health.

The liquid used in e-cigarettes generally consists of a blend of propylene glycol and vegetable glycerin (glycerol). Occasionally, a minor amount of water is included, but typically, it is absent. So, what exactly are propylene glycol and glycerol? These substances are relatively non-toxic organic compounds; however, it’s essential to remember that toxicity is dose-dependent. Inhaling significant quantities could lead to potential health risks.

Moreover, nicotine and various flavorings may be incorporated. Nicotine is the addictive agent, influencing both brain function and overall health. Within the liquid, two nicotine forms can be found, each capped at a concentration of 20 mg per milliliter: pure nicotine and nicotine salts, such as nicotine benzoate or nicotine tartrate. Flavorings, derived from organic compounds, are added to enhance the taste.

Chapter 2: The Mechanism of E-Cigarettes

How do e-cigarettes function? Often referred to as vaping, it’s crucial to note that this process is distinct from traditional smoking. The e-cigarette operates without combustion, hence avoiding the generation of many harmful substances typically found in cigarette smoke. Instead, a coil heats up, drawing in air that vaporizes the liquid. It’s important to clarify that what is produced is not vapor but rather an aerosol. The visible cloud exhaled is composed of tiny liquid droplets suspended in the air, rather than gaseous propylene glycol and glycerol.

The coil’s heating mechanism is critical for aerosol formation, with the temperature influenced by factors such as liquid quantity and resistance levels. A prolonged inhalation can elevate the coil's temperature, increasing the risk of liquid degradation and the creation of potentially harmful compounds.

Regarding health effects, the absence of combustion makes vaping less risky than traditional smoking, yet it is not entirely without danger. Short-term issues like airway irritation, coughing, and breathing difficulties have been observed, alongside potential long-term risks, including the formation of harmful and carcinogenic substances.

Additionally, the nicotine present can lead to addiction and has adverse effects on health, such as increased blood pressure and risk of diabetes. Therefore, while vaping may pose fewer risks compared to conventional cigarettes, it is not without its dangers. Ongoing research will continue to shed light on the side effects associated with e-cigarettes.
