Big vape news for big vape-men: The U.S. Department of Transportation has banned airline passengers from packing e-cigarettes and other battery-powered vaping implements—I don’t know? E-blunts?—in their checked baggage.

According to the U.S. Centers for Disease Control and Prevention, America's teens loooove e-cigs. They are trying them at a rapidly increasing rate and reporting that yeah, vaping is chill. CDC figures released today show that over 250,000 youths tried e-cigs last year, which is triple the number of kids who tried them in 2011.
