From the Fusion article: “The emergency contraceptive levonorgestrel—aka Plan B—was available in the United States for nearly 15 years before the idea that it wasn’t effective for women above a certain weight started getting attention.”
That should bother you, a lot. Neither the US government (which is currently controlled by people who want to own women) nor the manufacturer have done their jobs in making sure people know this, much less creating a better product.
If you or someone you know is a potential user of Plan B, please read and spread this information.
