More than 20% of sexual assaults in a sample of 882 victims were drug-facilitated sexual assaults, found a new study published in CMAJ.
Victims of drug-facilitated sexual assault were more likely than others to present to a large urban centre and to be employed, and to have consumed over-the-counter medications, street drugs, and alcohol before the assault.
Few studies have systematically measured the occurrence of drug-facilitated sexual assault and little is known about the victim profile, although this type of assault appears to have increased over the past 10 years.
The study, a collaboration between researchers from Women's College Research Institute in Toronto and the Ontario Network of Sexual Assault/Domestic Violence Treatment Centres, looked at data from 7 of these hospital-based centres. These centres served both rural and urban populations 24 hours, 7 days a week.
According to the self-reported data, 30% of victims had taken prescription drugs or over-the-counter medications (26%) and street drugs (27%) in the previous 72 hours before the assault. Almost 90% had consumed alcohol immediately before. "These types of substances have pharmacologic properties that can alter states of consciousness and lower inhibitions, especially when used simultaneously with alcohol and in their own right may be used to spike drinks," write Dr. Janice Du Mont and coauthors. "As such, victims could have unwittingly ingested a "date rape drug,"" although the combination of alcohol and drugs could also result in incapacitation.
The largest age group represented was 20-24 years (36%) followed by 16-19 years (23%).
