What is ketamine, the drug at the center of the alleged rape at Cornell?

What the coverage shows

Most outlets frame the story around ketamine or a legal gap in the Cornell 7 case: The Independent and The Washington Post both explain what ketamine is, while Vox centers the “loophole” and Reuters focuses on lawmakers seeking changes to rape law. National Review stands apart from the rest, using the case to argue about sexual liberation and a “moral wilderness,” a framing not shared by the other outlets.
