The nation's largest group of pediatricians is urging its members to write prescriptions in advance to enable teenagers to have fast access to the so-called morning-after birth control pill. "Emergency contraception is an important backup method for all teenagers," says a policy statement issued by the American Academy of Pediatrics. "Advanced provision increases the likelihood that teenagers will use emergency contraception when needed, reduces the time to use and does not decrease condom or other contraceptive use."

The faster you take it, the more effective the "so-called morning-after" pill is. But better than pre-prescribing it to teenagers, how about making it available over-the-counter?
