Nicotine is a pow­er­foul 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.
