Alcohol and Drug Facilitated Sexual Assault

Drug and alcohol-facilitated sexual assault is a deeply troubling and distressing issue that has significant implications for individuals and society. LeBeau Forensic Toxicology Consulting provides expert services to improve the investigation of these crimes.

What is Drug and Alcohol Facilitated Sexual Assault?

This form of assault occurs when drugs or alcohol are used to incapacitate or manipulate someone, making them more vulnerable to sexual exploitation and abuse. It is a violation of consent and personal autonomy, leading to long-lasting physical, emotional, and psychological trauma for victims.

The use of drugs and alcohol to facilitate sexual assault is often referred to as “date rape” or “drug-facilitated sexual assault.” Perpetrators may slip drugs into someone’s drink without their knowledge or exploit a person’s impaired judgment and diminished physical capabilities due to intoxication.

Common Substances in Drug and Alcohol Facilitated Sexual Assault

Substances commonly used include benzodiazepines, GHB (gamma-hydroxybutyric acid), and ketamine.  These drugs can cause drowsiness, memory loss, and confusion; effects that make it easier for assailants to take advantage of victims who may not be able to resist or remember the assault.

There are numerous challenges in the investigations of drug and alcohol-facilitated sexual assault, but they can be overcome with an understanding of the pharmacological effects of the drugs that are often used, as well as the toxicological testing that is performed.
