Hell’s Bells! Nicotine is damn poisonous. The LD50 is about 10 mg/kg. (The smaller the number, the less it takes to kill you.)

Hell’s Bells! Nicotine is damn poisonous. The LD50 is about 10 mg/kg. (The smaller the number, the less it takes to kill you.)

This is a complete myth. A good overview is at this site: The Great Nicotine Myth

Relevant snippets:

In October 2013, Prof Mayer of Graz demolished the myth: he showed that there is no evidence at all for the assumption that nicotine is highly toxic; and in fact the LD50 should be around 10 to 20 times greater than the current figure ...

His work shows that:

Evidence for the validity of the current LD50 simply does not exist

The method used to arrive at the LD50 is based on a guess made more than a hundred years ago

There is no evidence whatsoever that a dose equivalent to the current LD50 has ever killed anyone

There is overwhelming evidence that doses of multiple times the LD50 have been survived

Suicide by ingestion of 1,500mg of nicotine is known to have failed, the only result being abdominal pain and vomiting

There is strong evidence that the lethal dose is 4mg plasma nicotine, and this equates to a 500mg - 1,000mg dose

Bottom line, nicotine is not nearly as toxic as people claim it be.
