How Does Rohypnol Work?

Treatment for Three Decades and Counting

If you or a loved one is experiencing addiction, we’re here to help.

Rohypnol is a powerful sedative that acts as a central nervous system depressant. Rohypnol is significantly stronger than other common sedatives such as Valium. In most cases, Rohypnol is used in the short-term treatment of insomnia, as a pre-medication in surgical procedures and for inducing anesthesia.1

Rohypnol became prevalent in the United States in the 1990s when it was used as a date rape drug. This drug can be used in a variety of ways illegally such as crushing the pills and snorting the powder, sprinkling it on marijuana and smoking it, dissolving it in a drink or even injecting it.2

Rohypnol can also release growth hormones that enlarge the user’s muscles, which may make it popular among those looking for a quick physique boost.

Rohypnol can cause a number of immediate physical effects, including the following:

  • Intoxication
  • Loss of balance
  • Headache
  • Muscle relaxation or loss of muscle control
  • Difficulty with motor movements
  • Drunk feeling
  • Problems talking
  • Nausea
  • Can’t remember what happened while drugged
  • Loss of consciousness
  • Confusion3

Rohypnol often leaves individuals in a state of semi-unconsciousness or a coma. In some cases, sexual predators may add Rohypnol in powder or liquid form to the victim’s drink. When the drug is added to alcohol it slows the victim’s senses and bodily coordination. The effects of Rohypnol can last from eight to 26 hours, during which time the user has little to no memory of what transpired while he was under the influence of the drug.
