Recommendation 165
165
Accepted
Significant shift towards undetected New Psychoactive Substances (NPS) in prisons.
Conclusion
We are deeply concerned by the significant shift towards the use of New Psychoactive Substances (NPS), most notably synthetic cannabinoids and synthetic opioids. Their popularity is due to their affordability, accessibility and their potency. In turning to these drugs, prisoners are able to “cheat the system” as current drug testing systems fail to detect them. Therefore, it is also difficult to determine precisely the number of prisoners using these dangerous substances. (Conclusion, Paragraph 32)

Accept We review our drug testing processes on an ongoing basis to ensure they effectively monitor the constantly changing chemical composition of psychoactive substances. As the Committee recognises in their report, the scale of the challenge and the pace of change is high. There is a high volume of new psychoactive substances (NPS) observed in the EU market, with over 1,000 being monitored by the EU Drugs Agency at the end of 2024, including more than 270 synthetic cannabinoids. To respond to this, we regularly review drug testing panels across all testing modalities and draw on data from multiple sources, including our own testing results, quarterly prevalence studies by our testing supplier, and wider intelligence from cross-government partners and international agencies. These insights help us to identify the most likely emergent substances in prison drug markets and prioritise adding them to our testing capabilities. They also inform our contractual drug panel review meetings with our supplier every six months, where decisions are made on a case-by-case basis, considering cost, supplier capability, and evidence of prevalence. As a result of this established process, we have expanded our panels to include the most common synthetic cannabinoids and introduced testing for synthetic opioids such as fentanyl and nitazenes. Drug detection is a key research and development priority for HMPPS, and our efforts, working with wider partners, will focus on identifying and testing future solutions that provide frontline staff with reliable, indicative testing results in near-real time. Our long-term aim is to find new detection methods that show increased resilience to future drug threats and are easy to use for frontline staff.
