Nicotine is very toxic if ingested in large doses. It is NOT a carcinogen.
Nicotine is not classified as a carcinogen.
The first fundamental rule of toxicology is that it's not the toxin, but the dose. Water and oxygen, like all chemicals, are toxic, even lethal, in the appropriate dose. The general consensus is that "40-60 mg (0.5-1.0 mg/kg) of nicotine CAN be a lethal dosage for adult humans" (taken in one dose orally). It is broken down fairly rapidly by the human body, having an elimination half life of 1-2 hours.
The pharmaceutical industry is researching the use of nicotine for pain relief, relief of anxiety and depression, improvement in concentration and performance in those with attention deficit hyperactivity disorders; relief of some of the symptoms of acute schizophrenia; relief of some of the symptoms of Tourette's syndrome; relief of some of the symptoms of Parkinson's disease; and relief of some of the symptoms of Alzheimer's disease.
Nicotinic pesticides are approved for organic farming.
