Spiking can affect anyone, between May 2022 and April 2023, UK police recorded 6,732 reports, with 957 involving needle spiking (GOV.UK). While women are often more frequently reported as victims, all genders are affected. A 2022 YouGov poll indicated that 10% of women and 5% of men reported having been spiked at some point in their life.
Alarmingly, 90% of drink spiking incidents go unreported, because people feel embarrassed, unsure, or fear nothing will be done (Drinkaware). This underreporting suggests that the actual number of affected individuals is likely higher.
Reporting an incident can be daunting, but it matters. Not only can it help you access support and answers, it also helps protect others and makes venues safer for everyone.
Drink spiking – substances added to alcoholic or non-alcoholic drinks.
Needle spiking – drugs injected with a hypodermic needle, usually in crowded spaces.
Other methods – including food, vapes, or cigarettes.
The substances used are often colourless, tasteless, and odourless, which makes them hard to detect in the moment.
While the responsibility always lies with the person committing the crime, there are steps you can take to reduce risk:
Keep an eye on your drink – watch it being made or poured, and never leave it unattended.
Look out for friends – go out together, check in, and don’t leave anyone alone if they feel unwell.
Trust your instincts – if something doesn’t feel right, move to a safer space or speak up.
Call 999 if you’re in immediate danger or need urgent medical attention. If you can’t speak, call 999 and press 55 to alert the operator.
NHS 111 offers 24/7 medical advice if you’re feeling unwell or unsure what to do next.

If more time has passed since the suspected incident, hair strand testing offers a non-invasive way to detect drugs or alcohol use. At Cansford Labs:
We only need a small hair sample, making it a discreet and gentle process.
We remove standard cut-off levels in spiking cases to detect even the smallest traces, unlike routine drug testing.
Timing matters – waiting a few weeks allows hair to grow enough to carry evidence.
Fast turnaround times mean you don’t have to wait long for the answers you need.
Hair strand testing can provide clarity even if the spiking happened days or weeks ago, and may help support reporting or peace of mind. However, there are a lot of different drugs that could be used to spike someone, and sadly a lot of these are not standard. We have an eighteen-panel spiking test to try to include a broad range of possible spiking substances, but there are still some that may elude the test. Therefore, receiving a ‘not detected’ result does not mean that an incident did not take place.
Spiking can leave you feeling powerless, but knowledge is empowering. If you think you’ve been spiked, getting advice and testing—even days or weeks later—can give you answers and help you take action. At Cansford Labs, we guide you through this process with care, providing fast, non-invasive hair strand testing and support every step of the way. You don’t have to face this alone.
By raising awareness, encouraging reporting, offering preventative tips, and providing fast, accurate testing, we aim to help make socialising safer for everyone.
