How Does Rohypnol Work?

Rohypnol is a powerful sedative that it is not legally available in the United States. The black market supply available in the U.S. often arrives in shipments smuggled from Europe and Latin America. Rohypnol is significantly stronger than the more common sedative Valium and can be used to quickly achieve a deep hypnotic state or to relieve severe insomnia.

It first became prevalent in the United States in the 1990s as a date rape drug. 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
  • Nausea
  • Weakened limbs
  • Amnesia
  • Slurred speech
  • Drowsiness
  • Unconsciousness


The overall effect of Rohypnol use is often a state of semi-unconsciousness or a coma. 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 and allow the drug to begin shutting down the victim’s senses and bodily coordination.

Rohypnol effect’s can last from 8 to 26 hours, during which time the user has little to no memory of what transpired while he was under its influence.

Negative Effects of Rohypnol

Although the user may begin taking Rohypnol for a legitimate reason, such as to help him sleep or calm his seizures, it can be easy to overdose on this drug. An overdose of Rohypnol can have many damaging effects, including the following:

  • Inhibited breathing and heart rate
  • Permanent memory loss
  • Seizures
  • Vomiting
  • Addiction

The effects of an overdose can worsen if the user has taken other drugs at the same time, such as alcohol or heroin. Once the user is addicted, any attempt to quit without professional help will often end in frustration and continued addiction.

The addict’s loved ones may begin to see some signs of Rohypnol addiction in his behavior, including the following:
  • Symptoms of drunkenness without bearing the smell of alcohol
  • Lethargy and altered temperament
  • Refusal to answer inquiries about recent activities
  • Unexplained absence from school or work
  • Sudden financial problems
  • Severe withdrawal symptoms

Rohypnol’s highly addictive nature and uncomfortable withdrawal symptoms often prevent the addict from discontinuing use on his own. Rohypnol withdrawal can result in a number of symptoms, including the following:

  • Extreme change in mood
  • Aggravated insomnia
  • Recurring headaches
  • Hallucinations
  • Anxiety
  • Uncontrollable trembling
  • Shock

Seeking professional Rohypnol addiction treatment is the most effective way for an addict to safely detox from the drug and find lasting recovery.
