A Brief History of E-Cigarettes
Electronic cigarettes, also known as e-cigarettes, were first developed in the early 2000s by a Chinese pharmacist named Hon Lik. Since then, they have gained popularity across the globe due to their potential as a less harmful alternative to traditional cigarettes.
The Rising Popularity of E-Cigarettes
E-cigarettes have become increasingly popular over the past decade, especially among younger generations. They are marketed as a safer alternative to traditional cigarettes and as a tool to help smokers quit.
II. Understanding E-Cigarettes
Definition of E-Cigarettes
E-cigarettes are battery-powered devices that heat a liquid solution, known as e-liquid, into an aerosol that the user inhales. Unlike traditional cigarettes, e-cigarettes do not burn tobacco, but instead, they vaporize the e-liquid which often contains nicotine.
Different Types of E-Cigarettes
There are several types of e-cigarettes, including disposable e-cigarettes, pod systems, and mods. Disposable e-cigarettes are single-use devices that are discarded after the e-liquid is depleted. Pod systems are rechargeable and use replaceable pods filled with e-liquid. Mods are customizable, offering users more options in terms of battery power and e-liquid capacity.
Anatomy of an E-Cigarette
E-cigarettes have four primary components: the battery, atomizer, e-liquid tank, and mouthpiece.
- Battery: The battery powers the device. Its capacity can vary, affecting how long the e-cigarette can be used before needing a recharge.
- Atomizer: This is the heating element that warms up the e-liquid and turns it into vapor.
- E-Liquid Tank: The tank stores the e-liquid and feeds it to the atomizer.
- Mouthpiece: This is the part that the user inhales through.
III. The Science Behind E-Cigarettes
The Role of the Battery
The battery is one of the most crucial parts of an e-cigarette. It provides the power needed to heat the atomizer that vaporizes the e-liquid.
When the user inhales or presses a button, the battery sends electricity to the atomizer, which heats the e-liquid to create a vapor that can be inhaled.
The Transformation of E-Liquid to Vapor
The heat from the atomizer transforms the e-liquid into a vapor. This vapor contains tiny droplets of the e-liquid, which the user inhales.
Inhaling and Exhaling the Vapor
The user inhales the vapor through the mouthpiece, and it is absorbed into the bloodstream through the lungs. The user then exhales the remaining vapor.
IV. The E-Liquid
Components of E-Liquid
E-liquid, also known as vape juice, typically contains propylene glycol or vegetable glycerin, nicotine, and flavorings. However, nicotine-free versions are also available.
Variety of Flavors
E-liquids come in a wide variety of flavors, from tobacco and menthol to fruit and dessert flavors. This variety is one of the reasons for the popularity of e-cigarettes.
Nicotine Content Variation
E-liquids can contain different levels of nicotine, allowing users to choose their nicotine intake. Some e-liquids do not contain any nicotine at all.
CBD and THC E-Liquids
In addition to nicotine, some e-liquids contain cannabinoids like CBD or THC. These products are often used for medicinal
In a study, researchers found that blood from participants who used e-cigarettes or smoked caused a significantly greater decrease in nitric oxide production by the blood vessel cells than the blood from nonusers. Blood from e-cigarette users also caused more permeability in the blood vessel cells than the blood from both those who smoked cigarettes and nonusers. These factors can contribute to the impairment of blood vessel function in people who use e-cigarettes1.
Furthermore, it appears that the damage to blood vessels is not caused by a specific component of cigarette smoke or e-cigarette vapor, but rather by airway irritation that triggers biological signals leading to blood vessel damage, possibly through an inflammatory process. This makes it difficult to pinpoint any one ingredient in e-cigarettes that is responsible for blood vessel damage, and the researchers recommend avoiding these products altogether1.
