Rohypnol users often describe its effects as “paralyzing.” The effects start twenty to thirty minutes after taking the drug, peak within two hours and may persist for eight or even twelve hours. A person can be so incapacitated (made unable to act) they collapse. They lie on the floor, eyes open, able to observe events but completely unable to move. Afterwards, memory is impaired and they cannot recall any of what happened.
The person experiences loss of muscle control, confusion, drowsiness and amnesia.
