Rohypnol produces sedative-hypnotic effects including muscle relaxation and amnesia; it can also produce dependence. Rohypnol is not approved for use in the United States and its importation is banned. Illicit use of Rohypnol began in Europe in the 1970s and started appearing in the United States in the early 1990s, where it became known as "rophies," "roofies," "roach," "rope," and the "date rape" drug.
Another very similar drug is clonazepam, marketed in the U.S. as Klonopin and in Mexico as Rivotril. It is sometimes abused to enhance the effects of heroin and other opiates.
