In an article in Bloomberg Businessweek, it was reported that women in Texas are able to purchase abortion pills on the black market. The pills, sold under the brand name Cytotec, requires a prescription and is prescribed by doctors to prevent stomach ulcers. The pill has also been shown to induce abortions.
Women in Texas purchase the pills near the Mexican border for $40. If the woman were to go to a legitimate family planning center, a pharmaceutical abortion would cost $550.
