Alcohol misuse increases the risk of individuals either experiencing or perpetrating sexual violence.[15] Drug-facilitated sexual assault (DFSA) is a sexual assault carried out after the victim has become incapacitated due to having consumed alcohol or other drugs. Alcohol remains the most commonly used predator drug,[16] being readily available as well as legal, and is said to be used in the majority of sexual assaults.[11] Many assailants use alcohol because their victims often willingly imbibe it, and can be encouraged to drink enough to lose inhibitions or consciousness. Sex with an unconscious victim is considered rape in most if not all jurisdictions, and some assailants have committed "rapes of convenience" whereby they have assaulted a victim after he or she had become unconscious from drinking too much.[17]
