Understanding the science behind vaping is essential for those looking to grasp how e-shisha, or electronic Shisha, works. While it might seem like a simple process, vaping involves intricate mechanisms and chemistry. This knowledge empowers users to customize their vaping experience while appreciating the scientific foundation that makes it possible.
E-liquid and vaporization:
At the core of e-shisha is the e-liquid, a mixture of propylene glycol (PG), vegetable glycerin (VG), flavorings, and, optionally, nicotine. When you activate the device, an atomizer, often a coil of wire, heats the e-liquid. The high temperature turns the liquid into vapor. This process, called vaporization, is the fundamental science behind vaping.
Inhalation and exhalation:
As the e-liquid vaporizes, you inhale the resulting vapor. Unlike traditional smoking, e-shisha does not involve combustion. It produces a vapor cloud that contains tiny droplets of the e-liquid. This vapor is then inhaled, providing the sensation of smoking without the harmful byproducts of combustion.
Flavor and aroma:
The flavorings in e-liquids are essential for the vaping experience. These flavorings can be natural or artificial and are responsible for the wide variety of tastes available in the vaping world. The aroma and flavor are released as the vapor is inhaled, providing an enjoyable and customizable experience.
E-shisha devices often allow users to choose the nicotine strength of their e-liquids, ranging from nicotine-free to high concentrations. The nicotine in e-liquids is absorbed through the respiratory system, similar to traditional smoking. However, without combustion, e-shisha is considered a potentially less harmful way to consume nicotine.
E-shisha devices consist of several key components, including the atomizer (or coil), battery, tank (which holds the e-liquid), and a control unit. These components work in tandem to heat the e-liquid, vaporize it, and deliver the vapor to the user.
Chemistry of PG and VG:
Propylene glycol (PG) and vegetable glycerin (VG) are the two primary base liquids used in e-liquids. PG is thinner and provides a throat hit similar to traditional smoking, while VG is thicker and produces larger vapor clouds. Understanding the properties of these base liquids helps users choose e-liquids that match their preferences.
