Nicotine is a powerful neurotoxin to insects. Many plants other than tobacco contain it, however the concentration of nicotine in tobacco is exceptionally high. Even though some species have evolved the ability to feed on tobacco, it remains relatively easy to grow, being unpalatable to most species. In some places, tobacco became an invasive weed.
