What is Rohypnol? 

Rohypnol is a powerful benzodiazepine and acts as a central nervous system depressant. It has become widely known as the “date rape” because it has been used to sedate potential victims. In a medical setting, it has been used to treat insomnia and a precursor to anesthesia in some countries outside of the U.S.

How is it Used?

Rohypnol is commonly taken orally in tablet form but has also been used to sedate potential rape or sexual assault victims by dissolving the tablet in liquid. It has been known to be insufflated nasally.
