In other words, what the CDC is saying is:

Sadly, the agency concluded that it is not sure that e-cigarettes are any safer than tobacco cigarettes. The FDA states: "Many consumers believe that e-cigarettes are "safe" tobacco products or are "safer" than cigarettes. FDA has not made such a determination and conclusive research is not available."

Dr. Glantz is simply wrong. There is abundant evidence which demonstrates that while vaping does cause some degree of respiratory irritation (and probably triggers a bit of inflammation), it is far safer than smoking and has far less of an effect on lung function.
