Death of a worker occurred after ingestion of unknown amounts of Nicotiana glauca G leaves. The leaves were cooked after having been mistakenly considered to be spices of a type which grow in Thailand. After ingestion, two Thai workers collapsed, one with asystolia. Resuscitation efforts were successful only for one of the victims. A GC/MS method was used for the identification of anabasine as the main constituent in the leaves, food extract, blood, and the urine of the deceased. Lacking a standard, it was necessary to interpret the GC/MS spectrum to identify anabasine and establish its presence.
