In 1991, 1992, and 1993, legislators in more than a dozen states introduced measures that, had they passed, would have coerced women to use Norplant. Some of these bills would have offered financial incentives to women on welfare to induce them to use Norplant. Other legislation would have required women receiving public assistance either to use Norplant or lose their benefits. Some bills would have forced women convicted of child abuse or drug use during pregnancy to have Norplant implanted.
