TL;DR: Qualitative and quantitative analysis of methamphetamine and amphetamine in biologic materials was carried out by gas chromatography/mass spectrometry and blood was found to be the best material for estimation of the toxicity of the stimulant drug.
Abstract: Qualitative and quantitative analysis of methamphetamine and amphetamine in biologic materials was carried out by gas chromatography/mass spectrometry. A deuterium-labeled methamphetamine was employed as an internal standard with a detection limit of 50 pg and absolute stability and reproducibility. Blood was found to be the best material for estimation of the toxicity of the stimulant drug. It can be replaced by muscle which contains methamphetamine concentrations close to those of blood. The authors' classification of the toxic blood levels of methamphetamine from therapeutic to fatal doses was confirmed by additional data obtained from new case studies.
