I thought nicotine was a contact insecticide. I didn't know it was
also systemic. But it does bio-degrade quite rapidly apparently, so it
would soon break down when watered onto the soil or even if tobacco
leaves or cigarette butts were composted.

I picked up about nicotine being systemic in plants on some web site but
I do not know if it's true. It is systemic as far as humans are
concerned, hence the nicotine patch.
