Use of a two-drug combination now make up over half of all abortions in the United States, according to the Guttmacher Institute, an abortion research organization. About 350,000 Google searches using those terms or "abortion pill" were conducted during the week of May 1 to 8, according to the authors of the new research letter. That first week in May is when the Supreme Court's decision that would overturn Roe v. Wade was leaked and widely reported.
