Trends and challenges in the use of drugs as forensic evidence: A scientometric approach to map the current literature

The rapid increase in the production and distribution of illicit drugs has led to vast amounts of data being generated through research and other publications, making it difficult to effectively distill and analyze current and emerging trends. The present study used a scientometric approach to identify trends and challenges in the use of drugs as an evidence type in forensic science by examining reference lists available in the INTERPOL IFSMS reports and the citation database Scopus. It has been identified that “new psychoactive substances” is one of the most frequently used keywords by authors, highlighting the swift response by communities to characterize these emerging compounds. However, it was also noted that despite drugs being a global threat, only limited international collaboration was observed between research groups and the majority of the studies are from authors affiliated within the same country. Finally, an argument is made to encourage a more comprehensive approach in aggregating results on drugs for greater transparency and broader distribution of findings.
