An electronic cigarette is a battery powered vaporizer. It feels similar to tobacco smoking. Unlike cigarette smoke electronic cigarettes produce an aerosol which is known as vapor. Generally e-cigarette has a heating element which atomizes a liquid solution which is called e-liquid. An electronic liquid is a mixture of glycerin, nicotine, propylene glycol and flavoring. An electronic cigarette is much safer than tobacco cigarette in terms of tobacco use minimization. The main reason behind using an electronic cigarette is to quit smoking cigarettes and to cut down their smoking habit.
Due to limited evidence the risk and benefit of an electronic cigarette are uncertain. As an electronic cigarette contains less toxic substances than traditional cigarettes, it is safer than traditional cigarettes. The serious effect of an electronic cigarette is mouth inflammation, throat inflammation, cough, nausea and vomiting.
The earliest electronic cigarette was made by Herbert A. Gilbert which he named it as smokeless non-tobacco cigarette. It contained moist paper and flavored air heated nicotine solution for cigarette like taste but it was never commercialized. After that a Chinese pharmacist named Hon Lik invented the electronic cigarette. Later on in 2003 he made a cigarette using piezoelectric ultrasound emitting element which used to vaporize the pressurized jet of liquid which contained nicotine diluted in propylene glycol solution. The cigarette made used to produce smoke like vapor which can be inhaled. It provided a vehicle for nicotine delivery into bloodstream through lungs. After that various design of the electronic cigarettes were introduced and were commercialized.
As time passes many electronic cigarettes were continued to evolve from first generation to third generation. In 2006 “cartomizer’ , a mechanism which is used to integrate the heating coil into liquid chamber was invented by British entrepreneurs named Umer and Tariq Sheikh. Later on in 2007 a new device named “cigalike” was launched in the UK in Gamucci brand, which is now adopted by majority. Now the international tobacco company have recognized the potential of new market and are actively involving in the production and marketing of the electronic cigarette.
Generally electronic cigarettes are of cylindrical shape with wide array. There are three types of electronic cigarettes namely; cigalikes, which looks similar to cigarettes, eGos, which is bigger than cigalikes and mods, which is assembled from basic parts of existing product.
An electronic cigarette has four generations i.e first generation, second generation, third generation and fourth generation (future).
First generation: The first generation of e-cigarettes is called “cigalikes” because it looks like tobacco cigarettes. This generation e-cigarette can be designed as a single unit which contains coil, battery and filling saturated with an electronic juice in a single tube. And can be disposed after the battery is charge less or the liquid has depleted.
Second generation: The second generation e-cigarettes are larger than first generation e-cigarettes. It looked less like tobacco cigarettes. They contained larger non removable batteries which can be charged with a USB charger.
Third generation: Third generation of this E-cig includes 2 modes viz mechanical and variable voltage device in the battery section of the box. They are generally made up of wood, aluminum, steel or brass. Hardware can be modified to increase flavor according to the user needs. The fourth generation is coming to the market very soon and is going to be in the digital format.
People nowadays are addicted to the bad habits very easily and thus cigarettes addiction is not new too . So, for a solution of this serious problem E-cigs were made and this has helped people cope up with the demand of having cigarettes and plus it does not affect the held in that adverse way as compared to the E-cigs. E-cigs though contain nicotine and are highly addictive and thus it can help for stopping the habit but not completely remove since it provides nicotine in adequate dosages. It is not recommended for heart patients and might harm the arteries as per the survey.
E-cigarettes are although safer than the cigarettes but its not that these don’t harm. As said by Drummoned “E-Cigarettes are less harmful than cigarettes not unharmful”. Much information about this has not been known and we are studying about its long term effects and exposure in the society.
