Electronic cigarettes are battery-powered devices that deliver nicotine, flavorings, (e.g. fruit, mint, and chocolate), and other chemicals via an inhaled aerosol. E-cigarettes are currently not regulated by the FDA. In many states, there are no restrictions on the sale of e-cigarettes to minors.
Electronic cigarette exposures involving young children are rapidly increasing. Such exposures tend to involve patients aged < 5 years and occur by ingestion of the nicotine-containing liquid. There is a potential for acute nicotine toxicity (nausea, vomiting, pallor, diaphoresis, tachycardia, hypertenstion initially). Respiratory muscle weakness with respiratory arrest is the most likely cause of death.
To date, the overwhelming majority of pediatric ingestions have not resulted in serious medical outcomes. The most commonly reported adverse events were nausea and vomiting.
However, in May of 2014, the first pediatric case of toxicity from ingestion of e-cigarette nicotine liquid was reported. A 10-month old ingested an unknown amount of e-liquid and developed vomiting, tachycardia, grunting respirations, and ataxia. The symptoms resolved by 6 hours after ingestion without specific treatment.
