What is Rohypnol?

Rohypnol is the trade name for the benzodiazepine, flunitrazepam. It is used in the short-term treatment of sleep disorders, producing sedative-hypnotic effects including muscle relaxation.

Rohypnol is sometimes referred to as the date rape drug. This is due to its use being implicated in sex crimes where a victim’s drink is spiked with the drug, making them very drowsy or knocking them out so they’re either unaware of or unable to prevent a sexual assault.

Rohypnol is a prescription only medicine and a class C drug under the Misuse of Drugs Act. Supply without authority is illegal and Class C penalties apply (maximum 14 years imprisonment and/or fine).
