Ethanol in biological fluids: headspace GC measurement.

abstract：:This manuscript reviews data available in the scientific literature relative to drug testing for the five mandated drug classes and circumstances other than abuse of the drug itself that could result in a positive test. For marijuana, passive inhalation, unknowing oral ingestion, and the use of Marinol are discussed. ...
