ATLANTA — The federal government has cleared the path for consumers to buy the "morning-after" contraceptive pill without a prescription, but some Georgia politicians say they might fight to limit its distribution. The Food and Drug Administration on Thursday said women age 18 and older can buy the pill from pharmacies without first having to visit a doctor. Girls 17 and younger will still need a prescription. But that compromise — allowing pharmacy sales while excluding younger girls — failed to quell the debate over the pill, which critics say encourages promiscuity and poses other moral and practical problems. Previously available only by prescription, the pills will be sold only from behind the counter at pharmacies so the pharmacist can check photo identification, but not at convenience stores or gas stations.
