Guide to the Science of Vaping

Vaping is the modern method of inhaling and exhaling vapor originating from the vape juice from the process of heating. It uses an electronic vaping device equipped with a heating material which heats and evaporates the elements into vapor. The material used can either be e-liquid, herbs such as tobacco or any other element. Vaping has been considered to be safer and healthier compared to tobacco smoking as well as it exposes the user to reduced toxic chemicals. As it is combustion-free method, vaping technique, therefore, requires users to learn how to use the devices for the practice.

Components of Vaping Devices

Like many electronic gadgets, vaping devices also referred to as vaporizer, are available in different types, sizes, complexity, shapes, and performance. Some gadgets have a button to begin the vaporization while others require direct inhalation. Others are easy and quick to use while other devices demand some lessons due to their complex functionality for efficiency to users. Despite the design or features, vaporizers comprise of a battery, atomizer and a cartridge.


All electronic devices require a power supply which also includes vaping devices receiving their power from a battery for operation. The battery supplies the necessary power to the heating process which later vaporizes the vape juice for delivery of steam. The heating element also called the atomizer acquires the needed energy to vibrate the vaping material which therefore enhances the device performance.


The atomizer is the heating element which comprises of a coil and soft wick which heats the e-liquid to reach its boiling point hence releasing vapor. The wick absorbs the e-liquid which acts as a mechanism which regulates the amount of material being vaporized in the atomizer at a given time. The wick, therefore, ensures the amount of e-liquid burning at a given time determines the vapor released. Besides, the wick and coil can be controlled through acquiring a vaporizer with low resistance rate; thus the production of dependent steam at a given period.


The cartridge is the portion of the vaping device that holds the vape juice that can either be refilled or replaced. The e-liquid commonly used include propylene glycol, flavorings, and herb glycerin while currently exist various flavors such as tobacco, coffee, candy, and chocolate. Some e-liquids may have nicotine while others may not hence selecting the best vape juice is essential to ensure you get a perfect experience with the vaporizer.

Beginners are advised to acquire e-liquids from a reliable source as most products may include harmful substances. With multiple vaping devices and e-liquids already in the market today, it may become difficult for some individuals to determine the best quality to select from but always consider the habit, budget at hand and preferences. The components of the vaporizer may also be a factor when selecting the most desirable gadget that perfectly fits your requirements.

How the E-Cig Device Operates

The vaporizer heats and releases vapor from the e-liquid in the atomizer which is inhaled and exhaled by the user. An example of a vaporizer is the e-cig which is the most common rechargeable device in the market today. The e-cig comprises of different parts which include the aluminum body, a rechargeable lithium battery via USB, pressure sensor, pod or mouthpiece, atomizer, internal circuit board, and a color indicator.

E-Cig Atomizer

The e-cig atomizer comprises of the wick and coil which perform the heating and regulation of the vapor released. The atomizer uses the power from the lithium battery to excite the vape juice molecules which then vibrate and later break the bonds between them hence turning into vapor. The higher the substances in the vape juice, the higher the temperature for vaporization which is then passed to the pod or mouthpiece where the user can inhale. The range of temperature the e-cig can reach is between 392°F and 480°F across.

Ingredients in E-Liquids, Ratios, and Ohms

There exist hundreds of e-liquids in the market, but the most common include vegetable glycerin, nicotine, flavorings, and propylene glycol. The e-liquid used also depends on the resistance and the ratio between the two. Ohms is the unit of resistance hence responsible for determining the amount of heat resistance and the vapor generated from a specific vaping device. More so, vaping comprises of two methods, Mouth-to-Lung, and Direct Lung. Mouth-to-Lung involves inhaling to mouth then the lungs after a while and uses standard vaping of above 1.0 ohms and a 50/50 ratio. On the other hand, Direct Lung entails inhaling the vapor directly to the lungs and requires sub ohm vaping of below 1.0 ohms and a ratio of 70/30 or 80/20.
