Signs and Symptoms of Rohypnol Addiction

By Becca Owens

Rohypnol is a drug most commonly known for its reputation as a date rape drug. It is classified as a benzodiazepine and is a central nervous system (CNS) depressant. Benzodiazepines have the effects of sedation and relaxation on users; however, Rohypnol is much more potent — seven to 10 times — than more common benzodiazepines like Valium.1 Although legal in other countries like Europe and Latin America, Rohypnol remains illegal within the United States.

The US Drug Enforcement Administration Office of Diversion Control classifies drugs within five schedules based on three main qualifiers, which are accepted medical use, likelihood of abuse and addictive qualities.2 Rohypnol is classified as a Schedule IV drug, along with other benzodiazepines, even though it has no legal uses in the US. However, because of its dangerous nature to be used as a victimization tool for assault, it carries the same potential penalties of Schedule I drugs like cocaine and heroin.

Abuse of Rohypnol

Along with the common effects of other benzodiazepines, Rohypnol also causes partial amnesia, making the user forget what happened while under the influence of the drug. Because of this side effect, Rohypnol is often used as a tool for assault so that an assailant’s victim is relaxed and unable to remember the events of the crime.

Rohypnol is most often produced in tablets that can dissolve quickly in liquid and are odorless and tasteless. Although once colorless, in 1997 the primary manufacturer of the drug changed the chemistry so that it will release a blue dye when dissolved; however, colorless tablets still exist through generic versions.3

In addition to its abuse as a date-rape drug, Rohypnol is often abused among cocaine and heroin users. When Rohypnol is taken with these drugs, it boosts the high and gives an intense feeling of intoxication.4 Rohypnol is usually taken orally — often with alcohol for intensification — but can also be crushed and snorted. Most users feel the effects within 15 to 20 minutes of ingesting the drug, and the effects of Rohypnol can last up to 12 hours.5

Tolerance and Addiction

When taken regularly, users can develop a tolerance to Rohypnol, meaning they must take more and more of the drug to feel the same effects as they did with lower and less frequent doses. This process of building tolerance also often leads to physical dependence in which the user must take the drug in order to feel normal. Continued use after a buildup of tolerance and dependence often gives way to addiction.

Addiction is a chronic disease in which changes in the brain cause an addicted person to compulsively continue to use drugs despite negative consequences. People who have become addicted often exhibit behaviors like losing interest in once-loved activities, asking for money to get more drugs, being unusually moody and changes in sleeping and eating habits.6

Along with the common signs of drug addiction, people who are under the influence of Rohypnol often show the following effects:

  • A slowed psychomotor performance
  • The loss of bodily control and/or function
  • Disinhibition
  • Acting drunk
  • Nausea
  • Dizziness
  • Confusion 7
