Smoking of normal tobacco cigarettes cause severe health risks as they contain high level of nicotine and thousands of harmful chemicals. I was also smoking normal tobacco cigarettes, but now I used to smoke Electronic Cigarette due to various advantages. An Electronic Cigarette is a battery powered device that contains a cartridge, an atomizer and a solution of low nicotine level with some flavoring. Major advantage of electronic cigarette is that they do not harm and they smell good.
