Question

Nicotine is a small molecule produced by the tobacco plant Nicotiana tabacum. Nicotine is produced by the plant to discourage herbivores. In low doses, such as those experienced by tobacco users, it is a stimulant that leads to mild euphoria. In high doses, it acts as a potent neurotoxin. In these high doses, it has been used as an insecticide.
