The morning-after pill is quite different from an abortion that people mix up a lot. The morning-after pill or plan B prevents pregnancy rather than terminating it. The pill will save society money due to the reduction of abortions. A great advantage of the pill is that it can reduce a woman's ability to become pregnant to 2% if she has a 30%-40% chance of becoming pregnant after having unprotected sex. The morning-after pill has simple instructions and is easy to access over-the-counter if you're 18.
