| | vape pen is an electronic device that simulates tobacco smoking. It consists of an atomizer, a power source such as a battery, and a container such as a cartridge or tank. Instead of smoke, the user inhales vapor. As such, using an e-cigarette is often called "vaping". The atomizer is a heating element that vaporizes a liquid solution called e-liquid, which quickly cools into an aerosol of tiny droplets, vapor and air. E-cigarettes are activated by taking a puff or pressing a button. Some look like traditional cigarettes,and most versions are reusable. The vapor is primarily composed of propylene glycol and/or glycerin, usually with nicotine and flavoring. Its exact composition varies, and depends on several things including user behavior. Vaping is likely significantly less harmful than smoking tobacco. The life expectancy of tobacco smokers is at least 10 years shorter than for nonsmokers. E-cigarette vapor contains fewer toxins, in lower amounts, than cigarette smoke. Nicotine is addictive, but by itself is not greatly harmful. For people trying to quit smoking with medical help, e-cigarettes have a higher quit rate than normal nicotine replacement therapy. For others, e-cigarettes do not raise quit rates. E-cigarettes have evolved over time, and the different designs are classified in generations. First-generation e-cigarettes, which tend to look like traditional cigarettes, are called "cigalikes". Second-generation devices are larger and look less like traditional cigarettes.Third-generation devices include 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.There are also THC Weed Empty Disposable Vape Pens mod devices that use protonated nicotine, rather than free-base nicotine found in earlier generations, providing higher nicotine yields through the production of aerosolized protonated nicotine.The mixture used in vapor products such as e-cigarettes is called e-liquid E-liquid formulations vary widely. A typical e-liquid comprises propylene glycol and glycerin, and flavorings, nicotine, and other additivesThe flavorings may be natural, artificial or organic.Over 80 chemicals such as formaldehyde and metallic nanoparticles have been found in the e-liquid. There are many e-liquid manufacturers and more than 15,000 flavors. In the US, under Food and Drug Administration rules, e-liquids must comply with manufacturing standards. Industry standards are published by the American E-liquid Manufacturing Standards Association . EU standards are in the EU Tobacco Products Directive. | | This page has been viewed 26 times. |
