So I read this new study from Hopkins that says we're getting some metal in vapor. Not news to me I just always thought it wasn't more metal than is in cigarettes and the metal is a small part of what makes a cig bad. Still, I was reading the press release and it doesn't really make sense to me. The text said there are 15 micrograms of lead in vapor per KILOGRAM (median). I'm assuming that a kilogram of vapor is about a Kilo of juice. So if e juice and water are comparable in weight (are they?) that would be per liter of vaped e juice. By comparison there are two micrograms of lead in a cigarette. Am I interpreting this correctly or am I living in a dreamworld?
