Colorado regulators and prosecuting attorneys will not enforce a newly passed ban on so-called abortion-reversal treatment until rules governing the medication are written, they announced in a court filing Thursday. It could be several months — possibly stretching into early fall — before the Colorado Medical Board and the state boards of pharmacy and nursing finalize those rules. The law, SB23-190, states that a health care provider is subject to discipline if they engage in medication abortion reversal, unless those boards find it is a generally accepted standard of practice.
