Acute adverse effects
As regards e-cigarettes potential harmful effects, consideration should be given to acute injuries. A fair amount of reports to poison centers concern children incidentally exposed to e-cig liquids through ingestion (70%), inhalation (15%), ocular (8.5%) and dermal contact (6%)140. Nicotine poisoning can result in tachycardia, dizziness and even seizures141. Ingestion of 0,1 mg/kg of nicotine-containing fluid can be fatal to a child7. Acute exposure to e-cigarettes seems associated with a worse prognosis compared with that of conventional tobacco142. As electronic devices, batteries could also explode provoking severe burns143.
