Date Rape Drugs

Overview

Drugs that have been used in date rapes (sexual assaults) include flunitrazepam (Rohypnol) and gamma-hydroxybutyrate (GHB).

Gamma-hydroxybutyrate (GHB)

Gamma-hydroxybutyrate (GHB) is a central nervous system depressant. GHB is a clear, odourless liquid that looks like water and so can be added to a beverage without the person knowing it. It may also be used in the form of a white powder. GHB is also known as liquid ecstasy, G, or soap.

At low doses, the drug relaxes the person. The person feels intoxicated, has more energy, feels happy, and is talkative. Other effects include:

  • Feeling affectionate and playful.
  • Mild loss of inhibition.
  • Increased sensuality.
  • Enhanced sexual feelings.

GHB can cause side effects, such as headache, drowsiness, dizziness, and vomiting. It can lead to difficulty breathing, memory loss (amnesia), being conscious but unable to move, and loss of consciousness—especially when it is combined with alcohol or other drugs. GHB has been involved in overdoses, sexual assaults, and death.

This drug does not stay in a person's system very long and is not easily detected with drug screening tests (toxicology tests).

Flunitrazepam

Flunitrazepam (Rohypnol) is a central nervous system depressant. It is similar to diazepam (such as Valium) but about 10 times more potent. It is commonly called roofies. It is a tasteless, odourless tablet that can be crushed and dissolved in liquid. It has been used in sexual assaults, because it can be slipped into a person's drink without it being detected. One small tablet can produce effects for 8 to 12 hours.

Flunitrazepam is sometimes used to enhance the high of heroin or to ease the negative effects of a crack or cocaine binge. When flunitrazepam is mixed with alcohol, its effects may cause a person to become unconscious. It can produce a form of memory loss (amnesia) so that the person may not remember what happened while under the influence of the drug. Flunitrazepam may lead to death when mixed with alcohol or other depressant drugs.
