A growing number of spiking incidents are being reported in London, with perpetrators using substances such as spice-laced vapes and antihistamines to incapacitate victims, according to the Metropolitan Police. These incidents are increasingly occurring in domestic environments like house parties and student accommodations, rather than in bars or clubs. Police have noted a shift in the types of substances being used, moving away from traditional "date-rape" drugs like rohypnol and GHB to more commonly available over-the-counter medications and vape additives. These include synthetic cannabinoids like spice, THC (the main psychoactive component of cannabis), and high doses of antihistamines and travel sickness pills, which can cause drowsiness or confusion. Detecting and investigating these incidents is challenging, as the substances used are often metabolized quickly in the body, creating a narrow "forensic window" for testing. Spiking is frequently linked to theft, sexual assault, and other crimes, affecting both men and women. In the past year, over 2,700 spiking-related offences were reported to the Met, with a 20% increase from the previous year. However, only 131 of these cases led to formal charges, cautions, or summons. More than half of the victims were between the ages of 18 and 35, prompting police to urge university students to remain cautious, particularly during Freshers' Week, when social events are common. Detective Superintendent Dan Thompson, the Met’s lead on spiking incidents, emphasized that the tactics used by offenders are evolving, with a broader range of substances now being employed in private settings like homes and student accommodation. He stressed the importance of reporting incidents quickly—within the first 12 hours—to increase the chances of securing CCTV footage, collecting forensic evidence, and identifying witnesses. Police have also noted that criminal gangs are increasingly involved, using "spotters" and distraction tactics to approach vulnerable individuals. These suspects may befriend victims at parties or on nights out, gain access to their phones, and use them to steal money or personal information. Detective Superintendent Tony Reseigh, the Met’s lead on violence against women and girls, described these activities as "serious organised crime" and an "evolving threat." In the past year, Chinese PhD student Zhenhao Zou, 29, was sentenced to life in prison for drugging and raping 10 women in his London flat and in China. Police have warned that spiking incidents are occurring more frequently in student accommodation and flat parties. To raise awareness, universities across London are holding events during Freshers' Week, and students are encouraged to test their vapes for the presence of illicit substances using detection kits provided by the police.
