I should have check these numbers.... I got them from a
thread around
Fatal Dose of Nicotine?. I think there was a debate around these numbers but I didn't read the entire posts. My bad... Lets see " the lower limit causing fatal outcomes is 500–1000 mg of ingested nicotine, corresponding to 6.5–13 mg/kg orally. An accidental ingestion of only 6 mg may be lethal to children." That's pretty high for adults ~1/2 to 1L of 100mg/ml of nicotine.
It seems that there is still controversies on that topic. "A 2015 report on e-cigarettes by
Public Health England noted an "unconfirmed newspaper report of a fatal poisoning of a two-year old child" and two published case reports of children of similar age who had recovered after ingesting e-liquid and vomiting. They also noted case reports of suicides by nicotine. Where adults drank liquid containing up to 1,500 mg of nicotine they recovered (helped by vomiting), but an ingestion apparently of about 10,000 mg was fatal, as was an injection. They commented that "Serious nicotine poisoning seems normally prevented by the fact that relatively low doses of nicotine cause nausea and vomiting, which stops users from further intake"."
