Who ever the hell is saying this is stupid and shit is retarded. Its for people that are going to quit. My dad and step mom had one. It works, it has nicotine in it, for the idiots, that's the stuff ur addicted to. It makes the liquid nicotine a vapor and that's what you're "smoking" It does taste like a cigarette (parents told me). and it doesn't make any smoke. All you have to buy is nicotine cartridges that you put in the e-cigarette, and once in a while charge the battery. Its much cheaper than real cigarettes.
