If there might be other evidence, we’ll ask you to preserve it if you can.
Evidence can include something that the offender might have left behind at the scene that could help us prove what happened. For example, a glass or needle.
We understand that you may not be in a fit state to think of preserving evidence. It may help to ask a friend or a member of staff, if possible.
After you report a spiking incident, we may ask you to give us a urine or blood sample for a forensic test. This can establish whether someone may have spiked you.
Some drugs leave the body within 12 hours or much sooner. It's important to report spiking to us as soon as possible, so we can take a sample that could be used for testing.
But many other drugs stay in the body longer, so we might be able to test you up to seven days after the incident. Even after seven days, we might still be able to investigate and collect evidence.
If someone has spiked you with alcohol, there are other ways we can investigate what happened to you.
But although forensic testing can tell you and us whether someone has indeed spiked you, you're in control. If you don’t want to give us a blood or urine sample for forensic testing, that's fine. You can tell us what happened to you without testing and an investigation.
