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.

    在過去的20年，從掌上游戲機到小巧的筆記本電腦，電子產(chǎn)品已經(jīng)取得了長足的發(fā)展。事實上，現(xiàn)在，無論是制造業(yè)或電子產(chǎn)業(yè)自身，幾乎所有的物件上都至少有一個電子元器件。最新加入進來的又一電子小玩意是香煙。

    E-煙（電子香煙的縮寫）是一種可重復使用的電子尼古丁釋放器�？梢栽诮ㄖ�物內(nèi)使用，不必擔心觸犯"禁止吸煙"的法律規(guī)定，這種煙里面有3-4種成分，有助于減少卷煙，還沒有煙灰、煙頭兒，最主要的是比傳統(tǒng)的香煙便宜。（與真正的香煙相比）電子煙幾乎可以以假亂真，也有些外觀形狀像寫字的筆。電子香煙主要由三部分組成：電池，霧化器和藥管。

    裝上可充電電池，（尼古丁）霧化器就能工作。電池隱藏的位置相當于傳統(tǒng)卷煙的煙體部分。霧化器就是令電子香煙味道像真煙的那個部分。當吸煙者"抽"或吸煙時，吸到的是通過霧化器加熱的尼古丁液體的氣體。總之，藥管里面裝的是尼古丁的液體。藥管很小，是一個大約1英寸長、中空的塑料管。每個藥管里面可裝下一個更小的金屬箔密封膠囊。密封膠囊一旦打開，里面的液體就會變成氣體被吸入。每個藥管所含的尼古丁足以抵得上1包香煙所含的量。

    是什么使得電子香煙受到（煙民的）如此青睞？除了第一次購買那套裝置花錢最多之外，吸煙的成本相當?shù)土�。電子香煙霧化器價格從40 -100 美元不等，基本配置包括一節(jié)電池，霧化器，充電器和藥管。在不同的商店，藥管里面的尼古丁膠囊（通常是5包裝或10包裝）的售價在5-15美元之間�？偟膩碚f，吸煙者第一次得花75美元來買足夠的藥管，相當于一條傳統(tǒng)香煙的量，價格高低取決于吸煙者喜歡品牌，一般來說就是等同于一條香煙的價錢。

    吸煙者一旦成癮，一天吸一包（假定每包香煙6.5美元）,一個月的花費約是200美元。如果吸煙者使用這種電子煙，買替換的煙管（假定10包裝的15美元）,每個月將節(jié)省約155美元。
