Does an electronic cigarette with no nicotine classified me as a smoker?

Depends: It depends how you want to define "smoker." if you mean someone who takes nicotine into their body the answer is no. If you mean someone who has to put something in their mouth and go through the routine and ritual that smokers do, the answer is yes. Electronic cigarettes can be used as atransitional device to help you get over the habit of smoking. It is not usually a long term device.
