Is there any harm in e-cigarettes?

I just got a mini cig from e-cig.com and I really enjoy smoking it I'm just wondering if there is danger from smoking it too often? I have felt really light headed from smoking too much and I figure something about that can't be good or something about breathing in this vapor because it like normal cigarettes..

It is better in comparison of normal cigarettes and an effective way to quit smoking. It works more rapidly than gum and patches to quit smoking.
