Rohypnol (flunitrazepam) is a tranquilizer similar in chemical composition to Valium but is 10 times more potent. One milligram can impair an individual for eight to twelve hours. It is most commonly known as the “date-rape” drug because it is odorless, tasteless and can be unknowingly slipped into a beverage. Victims who have been drugged often awaken disoriented and suffer from memory loss. The drug is taken or administered orally, smoked or snorted.

Rohypnol is physically and psychologically addictive, producing sedative effects that force the muscles to relax and slow the response time of the central nervous system. Combining rohypnol with alcohol and other drugs, especially ecstasy, intensifies its sedative and toxic effects and can lead to heart failure, coma and death.

Short-term use of rohypnol can lead to sleepiness, loss of coordination, dizziness, confusion and decreased blood pressure. Long-term abuse results in anxiety, panic attacks, social phobias and amnesia. Withdrawal symptoms include muscle pain, headache, hallucinations, seizures and cardiovascular collapse. These symptoms intensify three to five days after use of the drug is discontinued.

Rohypnol is a Schedule IV controlled substance in the United States and is accepted for limited medical use.
