Rohypnol, a potent sedative-hypnotic drug prescribed extensively throughout the world, is illicit in the United States. Recently, this drug has gained popularity among United States youths as a cheap means of intoxication and subsequently has become the focus of numerous criminal investigations.

Presented here is a brief overview of Rohypnol's contemporary appearance in the United States.
