GC/MS distinguishes drugs based on how simple they volatilize. Sorry to say, but some drugs of abuse, do not volatilize. On the other hand, LC/MS method could separate substances and initiates them into the mass spectrometer. No specimen sample pretreatment is required, removing one of the problem steps in the GC/MS method. The results are 99.9% accurate. Liquid chromatography is the proper "Gold Standard!"
