Gas chromatography can show you what chemicals are in a pure sample that you put into it, it can't be used to test if people are on any type of drugs.

Was hoping someone with medical background would clarify. Are you that person, EnlightenedBrit?

If you submit a urine sample for GC/MS you need a library of compounds to screen against. In other words, you need to be already looking for it. Most standard drug tests screen for maybe a dozen drugs at most
