GC-MS is the "gold standard" of drug detection

Drug detection is best achieved through implementing gas chromatography-mass spectrometry (GC-MS) methods, it has been suggested.

Ronald Bugaoan, medical director of High Point Treatment Center in Brockton, Massachusetts, said GC-MS techniques are the "gold standard" of chemical analysis, MedPage Today reports.

He added that they help ascertain the levels of certain molecules in substances such as urine, which he highlighted as having the longest window for drug detection.

According to Mr Bugaoan, residents who are on the state's health plan can request GC-MS testing for a price of $12 (£8.20).

Writing for MedPage Today, Kristina Fiore noted tests such as these are better for returning more precise results.

GC-MS has a sensitivity of 99 per cent, she explained, although it is slightly more expensive than other methods.

Separation technologies were recently used to investigate the components of tar bells showing up on the coast of Florida following the Deepwater Horizon oil spill.
