Rohypnol is a very powerful drug, 10 times more potent than Valium. It's commonly associated with date rape, and many victims of drug-facilitated sexual assault (DFSA) test positive for Rohypnol.

Drug-facilitated sexual assault, including rape, involves any drug that is an incapacitating agent. This means that when administered to another person, it incapacitates the person and renders them vulnerable. Sexual predators looking to decrease the resistance capability of their intended victims may add Rohypnol in powder or liquid form to the victim’s drink. The drug will begin shutting down the victim’s senses and bodily coordination.

In many cases, Rohypnol victims aren't even aware that an assault has taken place until their symptoms are recognized or their memory returns.

When poisoned with Rohypnol, an individual may experience:

  • Loss of muscle control
  • Confusion
  • Drowsiness
  • Amnesia
  • Blacking out

The effects are described as paralyzing and start 20 to 30 minutes after consuming the drug, peak within two hours, and may persist for eight to 12 hours. The overall effect of Rohypnol use is often a state of semi-unconsciousness or a coma. Rohypnol is especially dangerous when mixed with alcohol and can enhance the feeling of being drunk, with exaggerated nausea, dizziness, and impaired speech and movement.

Rohypnol typically passes out of the system in 24 hours. It's sold in Europe and Latin America as a sleeping pill, but it's illegal in the United States. The black market supply available in the U.S. often arrives in shipments smuggled from Europe and Latin America.

Manufactured by Hoffman-La Roche, Rohypnol is the brand name for Flunitrazepam, which is a small white tablet. Flunitrazepam is an intermediate-acting benzodiazepine. The tablet can be crushed or snorted in powder form so that the effects can be felt more quickly. The most popular street name is “roofies” but the drug also goes by La Roche, the forget pill, Rib, R2, and Roofenol on Rope.

Substances Tested by US Drug Test Centers

How can you get tested? Testing for Rohypnol (Flunitrazepam) is available with a hair test. In addition to Rohypnol, one of the most common date rape drugs, there are other available tests that include other commonly used date rape drugs. These additional tests include Ketamine, Gamma hydroxybutyrate/gamma hydroxybutyric acid, also called GHB, and a much more comprehensive test known as an Unknown hair test. 


In addition to being a common date rape drug, Ketamine is a well-known street drug. Ketamine is considered to be a dissociative anesthetic (other examples of this drug are PCP and DXM).

Gamma hydroxybutyrate/gamma hydroxybutyric acid (GHB)

GHB is known as a depressant that often causes euphoric hallucinations. GHB is also sometimes used to treat sleep disorders when available as a prescription. Even consumed in small doses, GHB can be fatally toxic.
