Alcohol or Other Drug-facilitated Sexual Assault

What is alcohol or other drug-facilitated sexual assault?

Alcohol or other drug-facilitated sexual assault (DFSA) can occur when alcohol or other drugs are used to compromise or incapacitate an individual. This may result in lowered inhibitions, reduced ability to resist, and inability to remember details of an assault.

Symptoms may include:

  • Nausea
  • Loss of bowel or bladder control
  • Feeling drunk after consuming little or no alcohol
  • Sudden dizziness
  • Disorientation
  • Blurred vision
  • Memory loss

Drug-facilitated sexual assault is a crime

It’s illegal to:

  • Drug another person without their knowledge or consent. U-M policy defines consent as “clear and unambiguous agreement expressed outwardly through mutually understandable words or actions to engage in sexual activity."
  • Have sex with someone who is unable to give consent because they are incapacitated intoxicated, drugged or unconscious.

What substances can be used to facilitate sexual assault?

Alcohol is the most commonly used drug for sexual assault.  Other drugs may include rohypnol, GHB, GBL, ketamine and MDMA.

If you think you were drugged and/or sexually assaulted:

First, get to a safe place. If you need a ride at night, see Late Night Transportation

Next, it’s recommended to get health care. Be sure to inform health care providers about suspected drugging so they can order appropriate tests. 

  • In an emergency, call 911 or go to the nearest hospital emergency department. See Emergency/After Hours

Reporting is your choice: It is an option to report to law enforcement and to participate in U-M’s internal review process (where it applies), but you don’t have to -- it’s your choice.  You can have an exam and treatment without reporting.

How to reduce risk:

The following suggestions may reduce the likelihood of experiencing sexual assault; however, it is important to remember that is never someone's fault for being sexually assaulted, regardless of whether they take these steps or not.

As stated by RAINN, “Many survivors have strong feelings of self-blame after drug-facilitated sexual assault. They may feel that their choice to drink or to use drugs put them in a dangerous situation that led to the assault. It’s important to remember that if a sexual assault occurs under these circumstances, it is still not your fault. When you choose to use drugs or alcohol, you are not choosing to be sexually assaulted. The blame for this crime falls ONLY on the perpetrator.”
