 Exactly. And there are some unique risks associated with vaping that we don't have with conventional cigarettes. Now, while e-cigarettes don't have the tar from burning tobacco leaf that you get from cigarettes, e-cigarettes have flavors that are meant for ingestion, you know, that you'd swallow them and your stomach would absorb it. They're not meant to go into your lungs. We have virtually no science on what those flavors do to the lungs. E-cigarettes also contain heavy metals.
