The Drugs Team at Public Health Scotland (PHS) compiles RADAR quarterly reports of drug-related indicators. The objective of this report is to monitor drug-related harms, service usage and toxicology data, in order to provide an early warning of emerging drug trends and identify actions to reduce and prevent drug harms and deaths.

January 2026 - Main points: Drug-related harms remained high between September and November 2025. Although naloxone administrations fell compared to the previous quarter, they were 22% higher than in the same period in 2024. Most harms involved multiple drugs, reflecting continued polysubstance use. Significant market changes were also observed: clonazolam was the most common street benzodiazepine, detections of nitazene-type opioids in deaths reached their highest level to date, and cocaine remained the most frequently reported drug across treatment and toxicology data.
