Are electric cigarettes bad for you?

It would be unusual for an e cigarette to cause vomiting, however, different people have different chemical sensitivities or Allergies, so it would certainly be possible. However, any person who can smoke a regular, tobacco cigarette without vomiting would be able to inhale nicotine from an e cigarette without vomiting. And if you don't smoke tobacco, there really is no need to use e cigarettes either. The e cigarette is just a device to help people to overcome cigarette addiction. If you just inhale nicotine, that is a lot safer than inhaling smoke, with the tar, carbon monoxide, and other toxins that it contains in addition to nicotine.
