Electronic Cigarettes

Have you guys ever heard of electronic cigarettes, or e-cigarettes?  I must really be out of the loop because I had no idea these existed.  They come in flavors even! 

I'm not a smoker anymore.  I tried it when I was 15 years old for the first time and thought I was cool but didn't care for the taste (cigarette burps - gross).  Then I started when I was 23 for a couple years.  I stopped when my nephew made me feel really guilty about it and never smoked since.  Kids are good for that.  Our kids stopped my husband's cigar smoking he used to enjoy occasionally (on our front porch because I don't allow cigars or cigarettes in the house - don't even own an ashtray).  They asked him to stop and he did. 

I just had no clue that there were actually electronic cigarettes!
