(Daily Finance) — For women who don’t have regular access to affordable birth control — or who find themselves in an emergency — the birth control black market is just a click away. On Craigslist in New York City, a two-month supply of Yaz birth control pills is available for $60. A year’s worth of Ortho-Cyclen can be found for $50 in Los Angeles. And emergency morning-after pills, such as the over-the-counter Plan B, are available for $15, a considerable markdown from the $48 prices in pharmacies. Such online listings demonstrate a continued need for affordable and easily accessed contraception, says Dr. Vanessa Cullins, vice president for medical affairs at Planned Parenthood Federation of America. “We need to look at alternative avenues to provide birth-control services and viable options to women having to come into an office to be seen for each and every pill-refill visit,” she says. “When women are pushed against a wall, they will take action on their own.” Dr. Cullins says that birth control pills and emergency contraception are very safe to use for nearly all women. Her primary safety concern for women who acquire their pills through back channels is the possibility the pills might have been tampered with or that the medication might have expired.
