“Roofies.” Sounds like a cartoon character or a piece of candy. However, nothing could be further from the truth about Roofies, also known as the drug Rohypnol. Rohypnol (Flunitrazepam) is a type of benzodiazepine, a class of drugs that depresses the central nervous system. You may have heard of Valium and Xanax. These are also benzodiazepines used as sedatives and antianxiety agents. Rohypnol was developed as a sleeping aid. It is also used in therapy settings to relax patients and to get them talking. Rohypnol is manufactured in Europe and Latin American and is sold in many countries around the world. However, it is illegal in the United States and Canada. The pills are round, white and smaller than aspirin.
