Wikipedia: Flunitrazepam
Flunitrazepam, also known as Rohypnol among other names, is an intermediate acting benzodiazepine used in some countries to treat severe insomnia and in fewer, early in anesthesia.
 
Just as with other hypnotics, flunitrazepam should be strictly used only on a short-term basis or by those with chronic insomnia on an occasional basis. Flunitrazepam has been referred to as a date rape drug even though its incidence is very rare in reported rape cases. Along with GHB, MDMA and ketamine, Rohypnol is considered to be a club drug, due to its recreational use by dancers at raves, nightclubs and electronic dance music festivals.
