it is FDA approved and is actually sold in the U.S. as a generic called "Implanon"

The whole thing is a bullshit argument anyway. Libs def won't support anything mandatory and many conservatives don't want people to even know about birth control (witness abstinence only programs).
Even the conservative brain has trouble reconciling that sort of guided ignorance with the concept of mandatory birth control for welfare recipients.
"You remember all that birth control stuff we didn't teach you in high school, honey? Like last year? Of course not, because we didn't teach you that. We withheld the information, cuz, Values!, or sumpin'. That abortion you considered? Hey, we stopped that too. Now that you've been pumped, dumped, have a newborn & have applied for welfare, you're gonna have to get with the program, or else! We won't pay for any more babies!"
Compassionate Conservatives can praise Jesus for havin' it both ways, huh?
