Rohypnol is a brand name for Flunitrazepam, a powerful sedative in the benzodiazepine class of drugs.
Rohypnol has never been approved for use in the United States. However, it is legally prescribed for medical use in more than 50 foreign countries for the treatment of insomnia and as a pre-anesthetic.
Widely known as a date-rape drug, Rohypnol is abused more frequently for other reasons — to produce profound intoxication, boost the high of heroin, and modulate the effects of cocaine.
