Are vape pens with no tar, no nicotine, and no tobacco bad for you?

Seems safe: However, what you put into it can bring risks if that product is either illegal or toxic. So you might not risk cancer - but there are other things to avoid too. Take care!

There are 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.
