Nicotine is a potent neurotoxin alkaloid and is used in e-cigarette liquid. The LC/MS/MS method was linear over 0.01-1.0 mg/L (r2 = 0.992-0.995). Limit of detection and limit of quantitation were 0.001 mg/L (S/N = 3) and 0.003 (S/N = 10). ⋯ Only, high concentration of nicotine was detected in the gastric contents as well as the two pieces of evidence collected from the death scene. This fatal case resulted from oral ingestion of e-cigarette liquid. It is estimated that at least 714 mg of nicotine was orally ingested.
