Rohypnol Effects

Rohypnol is sometimes used in sexual assault because it can incapacitate victims, earning it the name “date-rape drug.”

Rohypnol users often describe its effects as “paralyzing.” The effects begin 20 to 30 minutes after taking the drug and can last up to 12 hours. A person can be so weakened and disabled that they can lie on the floor, eyes open, able to observe events but completely unable to move. Afterwards, they may have no memory of what happened.

Rohypnol is illegal in the United States, but it is sold in Europe and Latin America as a sleeping pill.
