Plan B, the emergency contraceptive that has been the focus of court battles involving the Affordable Care Act, has been shown to work by causing an abortion according to the medical data reviewed in The Linacre Quarterly.

The drug is one covered by the birth control mandate in the Affordable Care Act.  Health and Human Services Administration officials claimed that the drug is not an abortifacient drug and should be covered by all businesses.

The Hobby Lobby case at the Supreme Court had the justices ruling those drugs did not need to be covered.  Now, there is scientific proof backing up the claims of Hobby Lobby and other businesses that the drugs produce abortions.

The most recent scientific and medical evidence proves that Plan B “quite often” causes an abortion if taken before ovulation which is how women do not get pregnant after taking the emergency contraceptive.

The Linacre Quarterly is the official journal of the Catholic Medical Association.

Judie Brown, president of American Life League, told the Christian Post she agreed with the article’s conclusions.

“Catholic bishops have been assured, by Plan B proponents, that the drug does not cause an abortion,” Brown said. “We now know this is not true. There is a grave risk that preborn human lives are being killed by Plan B, and Catholic hospitals need to immediately halt dispensing these drugs and review their policies.”
