Bodies getting used to BC hormones?

[rockingsheep.livejournal.com]

Being a junior at a Catholic high school, I have to take a Christian morality class. Naturally, birth control gets brought into discussion a lot.
Today, my teacher (along with exaggerating terrible things about condoms) said that our bodies can get used to the hormones in birth control pills, and that they'll eventually stop working. My immediate response was, "That isn't true at all!" but I honestly haven't read about it anywhere.
I would love to be able to find an article proving this wrong and bring it to class to show my teacher. (Or an article saying this is true, and maybe I'll learn a thing or two.)

Do any of you have information about this? Has anybody even been told this before? I want to be armed with as much info as possible so kids don't get the wrong idea from our teacher.

That's so ridiculous. Using that same logic, one could assume that if a woman gets pregnant, she will also become immune to the hormones she is creating and would have a miscarriage.
