An electric cigarette [notes is an electronic device that mimics tobacco cigarette smoking. It includes an atomizer, a source of power such as a battery, and a container such as a cartridge or tank. Rather of cigarette smoke, the user inhales vapor, so utilizing an e-cigarette is called "vaping". The atomizer is a heating element that atomizes a liquid service called e-liquid.  E-cigarettes are triggered by taking a puff or pushing a button. Some look like traditional cigarettes. A lot of variations are reusable.
E-cigarettes produce an aerosol, typically called vapor, made from particulate matter. The vapor typically includes propylene glycol, glycerin, nicotine, tastes, and traces of toxicants, carcinogens,  heavy metals, and metal nanoparticles. Its exact composition differs, and depends on a number of aspects consisting of user behavior.
The health impacts of electronic cigarettes are unidentified,  however they are likely less damaging than smoking tobacco.

First-generation e-cigarettes tend to look like conventional cigarettes, though there is some variation in size, therefore are called "cigalikes". Second-generation devices are larger general and look less like conventional cigarettes. Third-generation gadgets consist of mechanical mods and variable voltage devices.  The fourth-generation includes Sub ohm tanks (meaning that they have electrical resistance of less than 1 Ohm) and temperature control devices. The voltage for first-generation e-cigarettes is about and second-generation e-cigarettes can be adjusted from 3 V to 6 V, while more recent devices can increase to 8 V. There are likewise pod mod gadgets that use protonated nicotine, rather than free-base nicotine found in earlier generations, offering greater nicotine yields through the production of aerosolized protonated nicotine.
E-liquid is the mix used in vapor products such as e-cigarettes. It usually consists of propylene glycol, glycerin, nicotine, flavorings, ingredients, and pollutants. E-liquid formulas differ extensively. A normal e-liquid makes up propylene glycol and glycerin (95%), and flavorings, nicotine, and other additives (5%). Some e-liquids lack propylene glycol,  nicotine, or flavors.The flavorings might be natural, synthetic, or organic.Over 80 chemicals such as formaldehyde and metallic nanoparticles have been found in the e-liquid. There are numerous e-liquid makers, and more than 15,000 tastes. 
In the US, under Food and Drug Administration (FDA) rules, e-liquids should adhere to producing standards.Industry requirements are released by the American E-liquid Production Standards Association (AEMSA). EU requirements remain in the EU Tobacco Products Regulation.
Many users start with a non reusable e-cigarette resembling a tobacco cigarette.   They often progress to later-generation devices and may change their gadgets to supply more vapor.Experienced users often choose rechargeable e-cigarettes.  Females choose non reusable e-cigarettes, and young people pay more attention to modifiability. Modifiability increases the chance of starting vaping among youths.
Most vapers utilize a refillable tank system, permitting them to blend their own liquid offering control over taste and strength.Experienced vapers rank customizability as the most important factor to consider in picking a device. Users ranked nicotine strength as an important aspect for selecting among numerous e-cigarettes, though such choice more info could differ by cigarette smoking status, e-cigarette use history, and gender.Non-smokers and unskilled e-cigarettes users tended to choose no nicotine or low nicotine e-cigarettes while smokers and knowledgeable e-cigarettes users favored medium and high nicotine e-cigarettes.
