"Pg. 10: Yeah, Juul and the like really are hurting children. Grades 2 & 3 Obesity are increasing too. Both are not good."

I read the charts a little differently - overall tobacco product usage has gone down quite significantly, with cigarettes and cigars driving the majority of that. I think it's a safe assumption to make that at least some of that drop is due to the switch to e-cigarettes like Juul. Obviously "how much" of that drop is due to the increase in e-cigarettes vs. the natural decline of smoking is in question, but I would not draw a conclusion that e-cigarettes are hurting children.
