Drug testing is a moving target. As novel psychoactive substances (NPS) rapidly emerge as a new class of designer stimulants (DS), global use has reached an all-time high over the last decade. Supposedly ‘legal’ alternatives to internationally controlled drugs, these compounds are typically manufactured ‘underground’ in unregulated laboratories by teams that are a step ahead of regulators. By simply altering the concoction of chemicals, the drugs slide under permissible legal radars.

With NPS-related deaths on the rise, the time it takes to detect these metabolites in forensic samples is critical. Clearly, there is a greater need for new technologies and methodologies to detect new substances and take an appropriate course of action to save lives. 

I Don’t Know What I’m Looking for (But I’ll Know When I Have Found It)
Trying to look for that “unknown” in a complex biological sample can be harder than finding a disguised fugitive in Grand Central Station at rush hour! It seems like an impossible task. The fast-paced nature of the market combined with widespread availability of an increasing number of substances is frightening. In fact, at the dawn of the millennium, the UN Office on Drugs and Crime (UNODC) listed only a handful of NPS. By 2008 the number was up to 26. Now more than 560 NPS are currently being monitored by the European Monitoring Centre for Drugs and Drug Addiction, with 100 new agents identified in 2015 alone.

Traditional drug screening tends to take a two-prong approach:

  • Screening: Using methods like Immunoassay or ELISA, toxicologists would screen for classes of abused or prescribed drugs. The pitfall― NPS assays are not always readily available for all drugs of interest; which leads to a greater chance of false positive results.
  • Confirm: A targeted confirmation testing approach using either GC/MS or LC-MS/MS. These methods are usually targeted in nature; limiting the detection of all ‘new’ emerging compounds. In addition, both methods are time-consuming.

Where Unknown Compounds Can Hide, We Can Find
It seems that identifying the unknown in the evolving designer drug market, knowns are not that simple. Fret not! High-Resolution Accurate Mass Spectrometry (HRMS) innovation such as the SCIEX X500R QTOF system coupled with a detailed toxicology screening method for 664 forensic compounds can do the job.

The good news? There’s a concise and comprehensive way to screen for unknown substances in your forensic evidence. This technote shows how our HRMS system powered by SCIEX OS Software work together. Discover a single-injection method for screening 664 most up-to-date forensic compounds, with library searching to automate and confidently establish the identification of unknowns in an efficient, all-in-one workflow.
