Why can schools freely hand out birth control while suspending kids who take aspirin?

Maybe they feel that it would be better to keep a girl from getting pregnant and keep her from committing suicide (OD on aspirin) at the same time? Haha, just a thought. They may think of it as a risk issue - whether they give out birth control or not, kids will have sex. Might as well hand it out to keep them from getting STDs and from getting pregnant. Yet they won't hand out aspirin (and they'll suspend those with possession) because people can both get high and die if they take a lot of the medicine.
