The nicotine contents of vegetables

Vegetable Nicotine in ng/g g per 1µg nicotine Cauliflower 16.8 59.5 Eggplant (Aubergine) 100.0 10 Potatoes 7.1 140 Green tomatoes 42.8 23.4 Ripe tomatoes 4.3 233.0 Pureed tomatoes 52.0 19.2

1µg of nicotine is the equivalent of sitting in a vaguely smoke filled room for three hours. Smoking a cigarette results in about 1mg absorbed nicotine. In other words, 100g of eggplant contains 0.01mg of nicotine, and 10kg of eggplant is equivalent to one cigarette. However, absorbtion rates from ingestion are low and nicotine is quickly metabolised, so the effect isn't nearly the same.
