I was thinking that for something to be logically considered a medicine it should necessarily aid in the healing from or prevention of an illness or at least be intended to.

There are disorders related to menstruation, like endometriosis, which can cause abnormally severe pain. Birth control is a method of treating endometriosis, and some women take the pill specifically for that reason. So birth control is a medicinal treatment for endometriosis.

PMS and PMDD are hormone imbalances that can be corrected with birth control. There is some evidence that birth control may even alleviate depression. So birth control is a medicinal treatment for mood disorders.

Birth control can also be taken to deal with acne, and some people take it specifically for that, too. So birth control is also a medicinal treatment for acne.

Not everybody takes birth control as a method of correcting disorders, but lots of people do. It has other effects besides suppressing menstruation and preventing pregnancy, and any deliberate use of those effects to correct medical conditions can be considered medicinal use by your own definition.

Watch how the affirmative side remains absent of thoughtful argument.

Being condescending is not a good way to kick off a debate.

Birth control helps girls with their monthly period. It makes the side effects, such as cramps, headaches, and being actually sick, disappear and it also makes the period shorter. I LOVE it.

Before I started taking birth control I would have to miss school the first day of my week long period because I'd be puking and have such terrible cramps I couldn't even get up. But since I started taking birth control the cramps are almost nonexistent, I never get sick anymore, and my period lasts three days every month.

I understand why a man wouldn't see these effects of birth control because they probably only think it prevents pregnancy, well for ladies, it does that and a lot more. It does heal us every month.
