Roofies, ruffies, roofenal: it’s a drug with many names that has become famous for all the wrong reasons. Flunitrazepam is a powerful sedative marketed under the name Rohypnol, and although it’s a prescription drug in Europe, it is illegal in the United States. But that hasn’t stopped people from finding it and using it, and it’s how they’re using it that is so disturbing. It’s become widely known as the “date rape drug” due to cases where men have secretly put it in women’s drinks to put them in a semi-conscious state and take advantage of them. The problem has become so widespread that four students at the University of North Carolina decided to do something about it.
