Many states aside from Texas have adopted laws that have restricted access to abortion. In 23 other states, abortion clinics must become certified as surgical centers. And in 10 other states, doctors who perform abortions are required to have admitting privileges at local hospitals. That has led to the closure of so many clinics that women have begun performing their own abortions. Many of these women are using a drug called misoprostol, which was originally developed to treat ulcers.
