The latest, most comprehensive data on the scale of drink spiking in the UK will be presented to the public for the first time at Anglia Ruskin University (ARU) on Saturday, 21 March as part of the Cambridge Festival , organised by the University of Cambridge.
Safe Sips: Navigating Drink Spiking is a free event in which members of ARU's Spiking Research Team will explain what drink spiking is, outline its effects on survivors and share the latest national findings.
Since 2021, forensic science academics at ARU have partnered with the UK's leading alcohol charity Drinkaware to track the prevalence of drink spiking through national surveys, undertaken by YouGov.
The most recent survey , carried out in summer 2025 and involving 7,256 UK adults, found that approximately 2% of adults reported being a victim of drink spiking in the previous 12 months. When extrapolated across the UK population, this equates to nearly one million people.
However, fewer than one in four (23%) of those who experienced drink spiking contacted the police. The most common reasons given for not reporting were not believing action would be taken by the police (39%) and not clearly remembering what had happened (38%).
Women were more likely to experience spiking, accounting for 58% of cases. The most frequently reported locations were bars (41%), social events (26%) and nightclubs (25%), with the highest number of incidents reported by adults aged 25-34.
Drink spiking involves adding a substance to someone's drink without their knowledge. Substances may include illegal or pharmaceutical drugs, or alcohol, and incidents are most commonly associated with sexual assault, physical assault, theft and "pranks". Giving someone stronger alcohol than they asked for, for example a double shot rather than a single, would also be classed as drink spiking.
As well as investigating the scale of drinking spiking in the UK, the ARU Spiking Research Team carry out extensive research into the types of samples that can be tested following suspected spiking and the detection kits and protective products that are marketed to the public.
The Cambridge Festival event will be led by Dr Lata Gautam, an expert in forensic and analytical chemistry, whose research focuses on drug analysis, the detection of drugs in spiked drinks and drug-facilitated sexual assaults.
Dr Gautam , Associate Professor in Forensic Science at ARU, said: "Drink spiking has increased in the public's consciousness in recent years, but our latest findings show that far too many cases still go unreported. With more than three quarters of victims not coming forward, it's vital that we raise awareness about the importance of contacting the police and seeking support.
"At the same time, there remain significant challenges in identifying the different substances used in spiking. This talk will share our latest research into analysing drink residues, as well as our evaluations of drink testing kits and other anti-spiking products that are being sold to the public."
Annabelle Bonus, Director of Research, Strategy and Impact at Drinkaware, said: "Drink spiking is a serious crime that can happen to anyone, anywhere. With our survey suggesting that more than a million people are affected each year, it is vital that victims feel confident reporting it to the police.
