My opinion is really mixed, despite the fact that the right to choose is something I strongly believe in.
On one hand, I think it will be great for women in small towns and in places where a 24-hour pharmacy isn't available. I've had women tell me about how they tried to get them, but weren't able to for whatever reason--from nurses being moralistic to hospitals simply not having it.
On the other, I know that women can abuse them. I have a friend who doesn't worry about having unprotected casual sex
because she can always get the morning-after pill, but she's sick as a dog after each time. I imagine that having it over-the-counter will make people like her be even less careful, but they're in the minority. My only health concern is that we simply don't know what those high-intensity doses do to our reproductive systems on the long-term.
