Is vaping a ecig without nicotine healthy or safe for your body or is it just as bad as a cigarette?

Don't know: What is in the vapor. If it is only water and there is a way to be sure it is not contaminated, it is not likely to be harmful.

Both have risks.: As of 11 SEP 2019 The Centers for Disease Control and Prevention reported 6 deaths & > 450 possible cases of severe lung injury in 33 states & 1 jurisdiction related to vaping. The mechanism of injury is poorly understood at this time. Don't recommend vaping.
