Nicotine poisoning describes the symptoms of the toxic effects of nicotine following ingestion, inhalation, or skin contact. Nicotine poisoning can potentially be deadly, though serious or fatal overdoses are rare.[1] Historically, most cases of nicotine poisoning have been the result of use of nicotine as an insecticide.[2][3] More recent cases of poisoning typically appear to be in the form of Green Tobacco Sickness, or due to unintended ingestion of tobacco or tobacco products or consumption of nicotine-containing plants.[4][5][6]
Standard textbooks, databases, and safety sheets consistently state that the lethal dose of nicotine for adults is 60 mg or less (30–60 mg), but there is overwhelming data indicating that more than 500 mg of oral nicotine is required to kill an adult.[7]
Children may become ill following ingestion of one cigarette;[8] ingestion of more than this may cause a child to become severely ill.[5][9] The nicotine in the e-liquid of an electronic cigarette can be hazardous to infants and children, through accidental ingestion or skin contact.[10] In some cases children have become poisoned by topical medicinal creams which contain nicotine.[11]
People who harvest or cultivate tobacco may experience Green Tobacco Sickness (GTS), a type of nicotine poisoning caused by skin contact with wet tobacco leaves. This occurs most commonly in young, inexperienced tobacco harvesters who do not consume tobacco.[4][12]
