The electronic cigarette is a small device created to look like a regular cigarette and provide a realistic smoking experience. However, instead of being filled with tobacco, it features a battery, an atomizing device, and an inhaler. The battery is often rechargeable, and one charge lasts around two to three days depending on usage. The atomizing device is heated by the battery, turning the liquid nicotine into vapour. This vapour is then inhaled through the inhaler. The liquid nicotine is contained at one end of the inhaler. When it runs out, all one has to do is replace that section of the electronic cigarette with a fresh cartridge. Each cartridge holds the same amount of nicotine as 15 standard cigarettes. The many benefits of the electronic cigarette are almost too numerous to count. The primary benefit of the electronic cigarette is that it contains no harmful substances. There are no tar or toxic carcinogens. Cigarettes contain more than 4,000 harmful chemicals, including ammonia, acetone, formaldehyde, pesticides, lead, carbon monoxide, and arsenic. None of these chemicals are found in the electronic cigarette. For many smokers, smoking is a social activity that can be enjoyed with their friends. However, non-smokers don’t always enjoy being around their friends when they smoke because of the issues created through passive smoking. The electronic cigarette removes this issue completely. There are also monetary benefits to using an electronic cigarette. It has been estimated that a smoker who regularly smokes ten cigarettes a day can save up to ￡770 a year. For those who smoke up to 40 a day, that number grows to more than ￡3,200 a year. That is quite the substantial savings. Because it features no tobacco, the electronic cigarette is not subject to any tobacco tax. Smoking has been banned in a number of public areas due to concern over second-hand smoke. The electronic cigarette is not affected by this ban due to its lack of tobacco and other dangerous chemicals. The legality of the electronic cigarette is not at the moment in question and many pub owners are more than happy to allow their patrons to use this device. This allows users to get their nicotine craving in public areas where they otherwise would not be allowed to smoke. A number of different pubs and clubs have begun allowing the use of electronic cigarettes on their property. These locations offer a great way for smokers and non-smokers alike to socialize and enjoy a night out without smokers needing to step outside or non-smokers feeling ill.
