In the past twenty years electronics have come a long way, from portable game consoles to mini laptop computers. Virtually everything now has to do with at least one piece of electronics either in manufacturing or the item itself. Cigarettes are the newest to take part in becoming just another gadget.

    E-cigarette, short for electronic cigarette, is a reusable electronic nicotine delivery device. This can be used in buildings, don't apply to "no smoking" laws, have three to four ingredients, saver then cigarettes, no ash, no butts and extremely lower cost than traditional cigarettes. Most resemble a real cigarette, while some look like writing pens. They consist of three main parts: a battery, an atomizer and a cartridge.

    The battery is rechargeable and allows the atomizer to work. The batteries are concealed in what looks to be the paper portion of a traditional cigarette. The atomizer is the part that makes the electronic cigarette perform like a real one. When the user takes a "drag" or inhales the air that passes through the atomizer heats up the nicotine liquid. Finally, the cartridge which contains the nicotine liquid. These are small, around an inch long, plastic and hollow. Inside each cartridge is an even smaller capsule with a foil seal. Once the seal is broke the liquid is then able to be inhaled as a vapor. Each cartridge contains enough nicotine to be the equivalent to 1 pack of cigarettes.

    What makes e-cigarettes so appealing? They are fairly low cost with the first kit being the most expensive. Kits can run from $40.00 up to $100.00 and include at least one of each, a battery, atomizer, charger and cartridge. Packs of refill cartridges （packs come in 5 or 10 per pack） can cost between $5.00 and $15.00 depending on the store. Overall a smoker can spend around $75.00 on the first order an receive enough cartridges to be equal 1 carton of traditional cigarettes and depending on the brand the smoker is use to that can and usually is the same amount they would pay for a carton.

    Once the start up kit is purchased a user that smokes a pack a day （we will assume their cigarettes cost $6.50 a pack） will spend around $200 a month. If that same smoker was to use an e-cigarette and purchase refills （assuming they spend $15.00 per 10-pack） the total savings would be around $155.00 per month.

    在过去的20年，从掌上游戏机到小巧的笔记本电脑，电子产品已经取得了长足的发展。事实上，现在，无论是制造业或电子产业自身，几乎所有的物件上都至少有一个电子元器件。最新加入进来的又一电子小玩意是香烟。

    E-烟（电子香烟的缩写）是一种可重复使用的电子尼古丁释放器。可以在建筑物内使用，不必担心触犯"禁止吸烟"的法律规定，这种烟里面有3-4种成分，有助于减少卷烟，还没有烟灰、烟头儿，最主要的是比传统的香烟便宜。（与真正的香烟相比）电子烟几乎可以以假乱真，也有些外观形状像写字的笔。电子香烟主要由三部分组成：电池，雾化器和药管。

    装上可充电电池，（尼古丁）雾化器就能工作。电池隐藏的位置相当于传统卷烟的烟体部分。雾化器就是令电子香烟味道像真烟的那个部分。当吸烟者"抽"或吸烟时，吸到的是通过雾化器加热的尼古丁液体的气体。总之，药管里面装的是尼古丁的液体。药管很小，是一个大约1英寸长、中空的塑料管。每个药管里面可装下一个更小的金属箔密封胶囊。密封胶囊一旦打开，里面的液体就会变成气体被吸入。每个药管所含的尼古丁足以抵得上1包香烟所含的量。

    是什么使得电子香烟受到（烟民的）如此青睐？除了第一次购买那套装置花钱最多之外，吸烟的成本相当低廉。电子香烟雾化器价格从40 -100 美元不等，基本配置包括一节电池，雾化器，充电器和药管。在不同的商店，药管里面的尼古丁胶囊（通常是5包装或10包装）的售价在5-15美元之间。总的来说，吸烟者第一次得花75美元来买足够的药管，相当于一条传统香烟的量，价格高低取决于吸烟者喜欢品牌，一般来说就是等同于一条香烟的价钱。

    吸烟者一旦成瘾，一天吸一包（假定每包香烟6.5美元）,一个月的花费约是200美元。如果吸烟者使用这种电子烟，买替换的烟管（假定10包装的15美元）,每个月将节省约155美元。
