Drug-Assisted Sexual Assault

There is increasing public concern about ‘drink-spiking’, with a perception that the chance of becoming a victim of rape or sexual assault after being unknowingly drugged is growing.

The Government is committed to tackling this problem, but we must do so in a measured and balanced way. It is important that any action is based on sound information, which defines not only the true nature of the crime itself, but also the extent of its prevalence. It is important not to perpetuate the circulation of myths and inaccuracies that may cause unwarranted fear or concern, while encouraging both men and women to take sensible precautions. As far as the evidence suggests, the commonest form of drug rape is facilitated by alcohol.

The very nature of this abhorrent crime makes evidence gathering and prosecutions extremely difficult. Rape is generally a crime that is under-reported to the police, and the disablement and confusion that is experienced by victims of drug rape can make reporting an incident even harder.

Advice on Preventing Drug-Assisted Sexual Assault

Nature of the problem

Findings from the 2001 BCS Inter-Personal Violence Module showed that in 5% of rape cases (using the 1994 definition) since age 16, victims said that they were drugged in some way; and in 15% that it was done when they were incapable of consent due to alcohol.

Unfortunately the list of substances that may be used in such cases is literally endless, with any substance which may have a sedative effect being a possible candidate.

There are at least nine drug groups and 14 specific substances that have been identified by various sources that can or have been used in cases of drug assisted sexual assault. This includes both controlled and uncontrolled drugs.

While drugs like Rohypnol and GHB (Gammahydroxybutyrate) have received wide publicity, they are rarely found in samples. From casework experience over recent years, only a small number of cases (1-2 per cent) contain unexplained sedative drugs and when unexplained drugs have been detected, they have been a mixture of controlled and medicinal drugs. It is often difficult to determine whether the drugs detected were actually taken knowingly or administered covertly.

Added to this is the fact that the effects of most sedative (both licit and illicit) drugs are dramatically increased when combined with alcohol.

The Government outlawed the drug Gammahydroxybutyrate (GHB), in July 2003. GHB became controlled under the Misuse of Drugs Act 1971, after the Advisory Council on the Misuse of Drugs (ACMD) recognised that it was being widely misused and had harmful effects.

This year, it is predicted that the Forensic Science Service (FSS) will receive 600 suspected drug facilitated rape cases. The FSS has also pointed out that in most samples sent for analysis, the findings are of a high level of alcohol rather than drugs.

However, we are acutely aware that these results are not a real representation of the problem. Unless samples are taken quickly, the traces of some drugs will have left the system by the time a forensic analysis is undertaken.

Action Underway

Operation Matisse: It is in recognition of these limitations that the police this year launched Operation Matisse. This six-month study involves the Metropolitan Police Service, Greater Manchester, Northumbria, Lancashire, West Midlands, Leicestershire and Derbyshire police forces. In these areas, a thorough forensic analysis will be carried out on all complaints of sexual assault specifically where the allegation involves drugs or alcohol being used to carry out the assault, allowing us to understand the extent of the problem and to establish some scientific data. It is the first co-ordinated study to look at drug-assisted sexual assault, and will provide valuable information on which effective action can be based.

Legislative action: The Sexual Offences Act has strengthened legislation on drug rape. The Act came into force on 1 May 2004 and makes it an offence to administer a stupefying substance with the intent of overpowering the victim to engage him or her in sexual activity, either with the offender, or with another person.

This offence carries a maximum penalty of 10 years imprisonment and can be charged whether or not a substantive sex offence takes place. Where a sexual offence follows the administration of a substance, this may be charged separately.

This offence replaces the offence of ‘administering drugs to a woman to obtain or facilitate intercourse’ which had a lower maximum penalty of 2 years. The new offence is gender neutral and drawn more widely, relating to all sexual activity, not just intercourse.

Awareness campaign on drug rape

The Home Office Drugs Prevention Advisory Service (DPAS) supported a drug rape awareness campaign called Spiked! The campaign was funded through Drugscope’s Millennium Awards scheme (funded by the Millennium Commission with the support of the Mentor FoundationUK and DPAS, and the Regional Screen Agency for the East of England). It was launched at the end of September 2003 in key United Kingdom (UK) and university cinemas and ran until November 2003. The infomercial aimed to increase awareness of the dangers of drug rape and make people aware of how they can protect themselves.

Action on rape

The Home Office published the Rape Action Plan in July 2002 (drawn up in collaboration with the police, Crown Prosecution Service (CPS) and court service) to improve the investigation and prosecution of rape cases. Although it does not relate specifically to drug rape, there are a number of measures we are introducing that include:
Launching an evidence kit to be used by first response police officers, to improve evidence collection

  • Reviewing victim examination facilities
  • Improved training for prosecutors and police officers
  • Rape Action Plan Report
