So it's another nasty habit/addiction.  I know they're kids, but it's still surprising how stupid kids can be sometimes.

A few weeks ago, my daughter turned to the desk next to her to talk to the girl sitting there.  When the girl talked, smoke started coming out her mouth, like a fire-breathing dragon (actually steam, I know).  She saw my daughter's frightened look and showed her the vape thing tucked into her sleeve.
