Well, you're damaging your lungs, that's for sure. And I've read that weed can hurt your fertility, too. (I know you're probably not thinking about kids at 18, but trust me, down the road you might hate yourself if you find out that you can't give little ones to the woman of your dreams.)
As to the metabolism thing, I don't know. but you're probably better off quitting, or at least severely cutting back.
