What are e-cigarettes
An e-cigarette is a battery operated (disposable or rechargeable) device that contains nicotine. The nicotine is turned into a vapor in the e-cigarette and then inhaled. The vapor looks similar to smoke. E-cigarettes come in all sorts of sizes and sometimes have flavored nicotine cartridges. When you "vape" -- that's the term for puffing on an e-cigarette -- a heating element boils the e-liquid until it produces a vapor.
