Birth Control Pills as Drugs?

Via feministing, a teenager in Virginia was suspended for taking her birth control pills at school. The school's authorities are claiming it's a case of worrying about liability, but I can't help but wonder if they would have made the same choice had she been caught taking anti-depressants or ADD medicine. Especially when I read this:

During two weeks of watching television game shows and trying to keep up with homework online, the Fairfax teen, an honor student and lettered athlete, had time to study the handbook closely. If she had been caught high on LSD, heroin or another illegal drug, she found, she would have been suspended for five days. Taking her prescribed birth-control pill on campus drew the same punishment as bringing a gun to school would have.

What do you think? A case of misdirected overly-cautious administrators? Or did they target birth control directly?
